It’s not just Polar Bears at Risk & dying but Humans are dying too due to Climate Change.
The villages in Kenya can be transformed having Solar PV Off Grid & Mini-grid systems - smallest systems are 10W - two lights and one phone charger. Larger systems are possible upto 130W for 240 V sockets for running fridges and TV and other commercial activities. The clans in the Provinces and Districts could actually “Own the Sun;s Reources”. “Resouce Ownership” Concept in action....... each District could collectively receive revenues from the Feed-In-Tariff of Kenya for every KW generated from renewable energy schemes. One such scheme would be phase four of Kenyalight - 10MW Solar Farm for Ngong.
Village Solar PV Pods
Smallest systems are for lights per dwelling &,
other larger systems could be possible - one 240 v socket per village hut
and one central village water bore-hole standpipe powered by Solar PV pump.
Mini (& micro) grids can take several forms/configurations.
Solar PV can be integrated at multiple points and the energy this generates will feed into the micro grid network and be consumed or stored in any/all of the battery modules on that network.
Our technology can be applied to creating a local grid network that has a central conventional generating source (e.g. a diesel generator) that then feeds to multiple distribution points each of which might have a hybrid/battery storage unit through which a distribution branch is fed.
The generator can be called to support the system in the event that the stored energy is depleted.
PSECC-Kenya would like to provide Solar PV to a total of ten Village Pod Mini Off Grid systems for each of the old 48 Local Authorities In Kenya, totalling 480 Village Pod systems and 48 Solar PV School Pod systems and 48 Hospital Pods.
We propose to the government of Kenya installing one light per room of each heard or house, totaling four lights with just one 240v socket per house or hut.
Sunny Money hits record sales through its Student Lights campaign - 50,000 lights distributed and sold already.
Sunny Money, the commercial arm of the energy charity SolarAid, sold more than 50,000 solar lights in Tanzania in the first half of this year through its on-going Students Lights campaign.
Sunny Money, which sells a wide range of solar lights, expanded its distributorship to the Arusha and Kilimanjaro regions, after a highly successful sales a year in 2011 on Tanzania Mafia Island.
Demand has far exceeded our ability to supply, and several times we have had to stop campaigning to wait for more lights to be imported. Even so sales have been running at 150% of budget resulting in over 50,000 solar study lights benefiting students in these two regions alone, says Malcolm Wigmore, SunnyMoney Operations Director in Tanzania.
Through its Student Lights campaign, the company demonstrates the use and benefits of solar lanterns to school children who can then buy the lights and enjoy clean, safe and affordable solar lighting.
Felista Mlay who lives in Rombo, Kilimanjaro and whose daughter purchased a light S1 solar lantern during one of the school campaigns, explains the impact the light has had on their lives.
Since we bought the solar light I have no worries at all about my children and the security of our home. The light has reduced our costs especially for kerosene. I used to buy two litres of kerosene each week,she says. Also my daughter was always complaining about eye irritation which was affecting her revision; breathing was also difficult due to smoke. But now I never hear any complaints.
In coming months, Sunny Money will be rolling out more school-based solar lighting promotions in the Iringa and Morogoro regions of Tanzania, with plans to also expand its operations in Kenya, Malawi and Zambia.
Using a similar approach, the company rolled out the Students Lightsâ€ campaign in Kenya and sold more than 20,000 study lights within 10 weeks.
very encouraging to see that the solar market in this country has grown to be trusted. The Kenya team is really excited about these campaigns and are planning to roll out more in other areas,says Linda Wamune, the Kenya Operations Director, as the team plans to scale out its schools campaign.
Based on performance to date, SunnyMoney is confident of achieving sales in excess of 300,000 solar lights this year, says the Managing Director, John Keane.

A Solar Strategy for Africa: International Players Set To Expand Key Markets - PSECC provide mechanism for Solar PV
By Mark Hankins, Africa Solar Designs
Now that real progress has been made in growing global demand and production and lowering costs in developed countries, it is time to
think seriously about kick-starting real solar markets in Africa.
There is a need for a shift in focus on solar markets in Africa away from donor and rural electrification projects to commercial and productive investments.
There is also a need for the international PV industry to aggressively invest in the development of solar markets and not to leave it up to aid and relief organisations.
This must be based on the need to move – today – towards grid-connected and urban markets. As part of this process there is a need to engage and educate
African governments about the current global status of the solar sector and help them build frameworks for industry growth.
Markets for small off-grid systems, those below 100 Wp, are important to kickstart solar industries, but they will be less important in the long term as demand for
them begins to fall.
It is also useful to have an idea of where marketing and development efforts will lead in the long term. 'Off-grid rural solar development' in Africa has dominated
discussion for so long that we seem to have lost the bigger picture. Where does the solar industry want to be in Africa in 10 years? Leaving aside the 'rural
electrification' impact, which is more attractive for a solar company: 20,000 solar home systems at 50 Wp or 500 systems of 2 kW each? Both will result in
1 MW of sales.
Kenya's so-called 'solar PV success story' is a good example of this. Its focus on small systems – to the exclusion of larger commercial or grid-connected systems –
and has resulted in an annual PV market of 1.5 MW that is low-tech, over-the-counter and dominated by small products. But the market is stagnating.
Continued efforts by aid groups to build sales in 'poverty markets' will likely increase the depth and accessibility of small scale lighting systems. However, this will
not build a market with a 20 MW/year solar demand of a scale that is interesting to larger PV supply companies. No matter their importance to the rural poor, LED
lanterns with 1 W modules fall into the realm of the fast moving goods providers from Asia, not solar PV companies.
If healthy markets that are multi-dimensional and sustainable are to develop, solar advocates must prepare the ground for the variety of viable niches that will be part
of a healthy long-term solar market. In addition to village electrification, this includes off-grid markets such as telecoms, tourism, business and pumping as well as
grid-tied and utility-scale markets.
Africa is not solely a poverty market and, in the long term, middle class and commercial groups will do far more to develop solar markets than procurement-driven
public sector projects or the efforts of humanitarian groups.
Every car salesperson knows that, when a customer enters a showroom looking for a luxury car there is probably no need to show the second-hand hatchbacks.
But, in Africa, the solar sales approach shows high-end customers bicycles, not limousines. Africa's most important buyers go for generator sets because they
see generators as being 'classy' and practical solutions - and generator dealers latch on to this. Solar agents do not recognise this market.
The Flawed 'Aid' Approach to African Development
The aid-dominated approach to PV in Africa has led many decision-makers in Africa to believe that solar is about helping poor people. Without detracting from the
hard work of solar NGOs, village solar electrification is relief work and should not be confused as being the foundations of a developing market. If building real markets for solar in Africa, and in doing so reducing carbon emissions, is the objective, NGO contracts to supply a thousand lanterns or government procurements for 100 schools are, at best, stepping stones, but they are not the long-term answer to stimulating wider demand and building solar futures.
Too many people think of Africa in terms of desperate unempowered off-grid rural poor people with no cash. Aside from a lot of sunshine, the continent's agricultural
sector is growing as are its mineral exports. In some areas, Africa is also seeing massive building projects, along with more frequent traffic jams as automobile sales
increase rapidly, and more and more power shortages as electricity companies struggle to meet spiralling demand. Where there is money – and power shortages -
there is a market for solar power.
The multi-megawatt PV project market is coming to Africa, but not yet. To deliver large-scale projects, a focus on intermediate-sized 50 kW to 200 kW installation
market segments is required.Developers, financiers, solar companies and governments want to push the envelope and open up new markets in Africa. But most are thinking big, and perhaps a
bit too big, for the present undeveloped state of the market. For example, a finance house developing PV project portfolios for African countries, while eager to hear
ideas for innovations in Africa, was unwilling to discuss projects below 1 MW.
On a continent where the largest installed system is 250 kW (Kigali, Rwanda) a 1 MW minimum requirement is unreasonable as a starting target. Even though grid
parity is close in a number of countries, outside of South Africa the type of feed-in tariffs and incentives necessary for megawatt-scale projects are simply not feasible.
Resistance from utility sectors can make agreements problematic and risky for investors whereas smaller-sized projects may be able to fly under the radar and build
up experience as solar is assimilated into power sector planning. When experience is gained on one or two 50 kW projects in a country, these can be bundled by developers into financially attractive packages. But the first step is to gain experience.
There is a need for developers, perhaps with donor agency help, to think bigger than village scale, but a bit smaller than utility scale. Just 10 years ago 50 kW PV projects made industry headlines in Europe.
Grid connection is coming in Africa, perhaps faster than expected and definitely in different ways than expected. In the near future, urban PV markets will be as
important as rural markets.
In the mid-1990s, when the annual world production of PV was well below 100 MW, many ridiculed the idea of grid-connected solar anywhere in the world.
Off-grid rural solar electricity made much more sense. How could grid-connected solar prosper when off-grid markets were screaming to be satisfied in developing
countries all over the globe?
In every country in Africa the electricity sectors plan to eventually connect all economically active areas to a national grid system. Arguments and concerns can be
raised about how fast this will occur – or even whether it makes sense – but the fact is that politicians, planners and consumers are united in their desire for grid
electricity. Because virtually all solar in Africa today is off-grid, ministry planners often view solar as a second class option for remote locations where it is likely to
be too expensive to establish a grid connection and where there is little economic activity. It is time for those planning national strategies to look to solar –
and those developing solar marketing plans – to embrace on-grid solar and stop pretending that solar is exclusively for off-grid communities in Africa.
Some say that fragile African grids, with fluctuating voltages and frequent shutdowns, cannot accept PV power but the same thing was said about wind a few
years ago. Now there are multi-megawatt wind projects all over the continent. Surely, the opposite is true - grid connect solar systems can help stabilise grids and,
with small battery banks, can also help consumers weather power outages.
While there are definitely technical, financial and regulatory hurdles to be overcome there are also huge opportunities. From Lagos to Nairobi and from Addis to
Dakar, businesses, hotels, offices and households today buy and install hundreds of thousands of generator sets and battery-inverter systems to hedge against
brownouts. Because electricity can be unreliable in African cities people who require continuous power are willing to pay extra to ensure their supply and therefore
surely it makes sense to use this willingness to pay as a wedge to open new grid-connected PV markets.
Given the choice, a substantial proportion of the middle classes, NGOs and business consumers in Africa would purchase grid-connected systems. Educated
Africans will install solar for the same reasons that people in the North do – because it is clean and silent, reduces carbon footprints, is modern and aesthetically
Net-metering, not feed-in tariffs, will initially be key to developing grid-connected markets, just as they were in Germany and the US.
For medium- to large-scale renewables such as wind, hydro and biomass, specialised feed-in tariffs are important policy tools to stimulate investment. Even in
Africa (RSA, Kenya) feed-in tariffs are helping to get renewable power projects off the ground.
However, feed-in tariffs are less suited to PV than other renewable technologies for several reasons. First, there is much less economy of scale in PV; it does
not matter whether a PV installation is 10 kW or 1 MW – the costs are broadly the same. Secondly, because of this scale issue, thousands of dispersed PV
installations make as much sense as a single large plant. But right now PV is still more expensive than wind, hydro or biomass, so it is hard for governments to
justify PV as part of their 'least cost power plan'. However, there is no need to block private consumers who want to invest in Africa's nascent solar market.
Net metering is a low-cost policy tool that allows electric utilities to incentivise on-grid PV investment by private consumers. With it, consumers invest in a PV system.
Instead of storing their PV power in a battery during the day, they store it on the grid by running their meter backwards and selling their output at a retail rate. In the
evenings they draw back the electricity that was generated during daylight hours, with the result that at the end of a month consumers could potentially have a
Unlike feed-in tariffs, net metering does not require massive grant support or additional levies on electricity consumers by cash-strapped African governments.
Net metering cannot be unscrupulously 'rigged' because there is no incentive – electricity bills are offset, and no cash changes hands. Net metering also allows
demand to develop naturally. Those who want solar PV and are willing to pay a premium for it will be rewarded. In short, those that want to buy and sell PV power
should be encouraged, not discouraged.
The Benefits of Solar
In Africa the versatility and practicality of solar energy solutions is as important as the cost/kWh.
Too often, electricity is judged on extremely narrow price grounds. Policy-makers, from both government and donor sides, look at the cost/kWh of solar and
automatically disqualify it from discussions in national planning. African energy departments, and the donor agencies that support them, apparently dismiss
solar out of hand because of its high costs. The mentality, it seems, is that Europe should busy itself with developing the PV as Africa cannot afford to do so.
But at the same time, in countries as divergent as Kenya, Rwanda, Senegal and Burkina Faso, petroleum-based generation is sacrosanct when it comes to
investments in power supply. Thermal generation units are purchased to meet 'emergency' peak demands because petroleum flexibly supplies power when it is
Even though solar PV is an expensive investment it can be an extremely reliable and predictable component source of an overall electricity profile during periods
when electricity is needed.
It is especially valuable during cloudless periods when dams dry up and grid managers must scramble to get thermal units on line, and nothing seems surer than the
fact that as petrol prices will invariably rise the costs of developing and installing relevant and efficient PV solutions will fall.
PV can be deployed in a decentralised manner where it is needed and where space is available. Financing can also be decentralised. The same customers
who buy their own generator and battery back-up sets may consider investing in solar as an alternative to brownouts.
But perhaps most importantly it is necessary to pay the high up-front prices of solar today to build the experiences and capacities that will be needed tomorrow.
Solar did not happen in Germany and California overnight; it took decades of work to get the skills, supply lines, finance and consumer awareness in place.
Governments cannot wave magic wands and make these things happen, at which point solar suddenly becomes 'cost-effective'.
Before achieving 200 MW of installed capacity, a first target of 1 MW has to be reached.
The Role of Industry
Over the past two decades, as solar markets have grown at double digit rates in the North, the job of building up solar markets in Africa has been left to NGOs
aid agencies such as the UN, the World Bank and the Global Environment Facility.
Few African governments have championed PV, and most of the companies that did have offices in Africa have left. This needs to change. As stand alone generator
and petroleum-based power suppliers already know, Africa is a steadily growing market – and a profitable one at that.
Donor agencies have relegated PV to off-grid markets and, moreover, they have left the administration of PV projects to slow-moving government agencies.
Few major solar players want to bid on World Bank-supported government tenders that can take years to develop and which can be expensive.
Thomas Edison and Henry Ford had it right. When they developed their electrical lighting and automobile products, they aggressively took them to the moneyed
classes in large American cities and their companies were successful. With more solar resources than anywhere else in the world, with steadily growing economies,
and with massive shortages of power, the markets in Africa are ripe. But Africa needs solar entrepreneurs that can convince the buyers and it needs the type of
aggressive green investment that took place in the 1990s in Europe.
Solar industries need to work together to build viable markets in Africa and should instead leave the World Bank and the UN to focus on the off-grid poor.
Aid efforts should focus on helping to steer solar policy in the right direction, and tying grant and subsidy support to the achievement of targets. This will require the
active long-term engagement of governments, the private sector, civil society, and the international solar industry.
The global boom in solar – and the accompanying fall in PV prices – has occurred because a handful of countries realised that it would take strong policy initiatives
to get PV markets to a size that would bring solar prices to back down to earth. Bold politicians bet on solar and we are now beginning to see the fruits of those measures.
Because of a lack of disposable income and difficulties, perceived or real, in doing business, Africa has been largely side-stepped in solar energy development
Slapping donated modules onto the roofs of rural clinics is an easy way to leave the impression that something is being done in Africa. Of course it is easier to target
support for schools, clinics and village electrification, but until policy frameworks are in place to build sustainable solar energy industries, much international solar aid
support is being wasted on projects in remote locations with no infrastructure and little cash. Sustainable local solar businesses are simply not being created.
As is the case with coal and nuclear industries in the North, there are entrenched interests in many African countries that do not necessarily embrace solar.
Numerous ruling elites manage profitable petroleum and large power project cartels and they could be expected to block decentralised solar and grid-connected
projects. International solar industries and development aid networks that are seeking to build solar markets need to be aware of these interests and find ways to
help civil society empower itself with solar.
As power prices in Africa rise, grid expansion stalls and as grid power availability is constrained, consumers and communities increasingly have to take electricity
production into their own hands. In the long term, this is a good thing, and having a portion of electricity coming from decentralised solar sources is healthy for any grid.
Just as political systems in Africa have evolved to reflect the needs of educated voters, power sectors must change too to allow new segments of the population to
profit from and participate in electricity production. This is the promising future of solar in Africa.
Mark Hankins has worked in the African solar energy sector for 25 years. He manages Africa Solar Designs, a Nairobi-based solar solutions provider that is
currently developing on- and off-grid PV projects. He recently authored 'Stand Alone Solar Electric Systems' published by Earthscan Publishers.

on fishing and its trade with nearby villages. The need of ice, which so many of us take for granted, is a matter of survival for the inhabitants of Monte Trigo.
They need it for preserving the fish, hence the constant and frequent five-hour boat trip (each way) to São Vicente, the nearest main island, for ice purchase.
It is a process far from efficient, wasting precious time that could be used in other activities.
Let there be light
It was to respond to this need that local entities came together to develop an off-grid solar energy project. It was financed under the ACP-EU Energy Facility
programme and lead by local private water company “Aguas de Porta Preta” (APP), in consortium with the local Municipality (“Câmara Municipal de Porto Novo”,
CMPN) and other entities.
The facility installed in Monte Trigo is a Multi-user Solar micro-Grid (MSG) based on a photovoltaic generator, a storage battery, an electricity monitoring, control
and power conversion equipment and an LV distribution grid. The 27.3 kWp PV generator is mounted on a wooden pergola that provides shade to the village’s
schoolyard and therefore added value to the community. Power from the PV power plant is delivered through an 800-metre aerial distribution line to the 60 final
end-users, among them a school, a church, a kindergarten, a health centre, a satellite DVB TV system, three general stores and 22 streetlights.
Challenges and added-value of controlling energy demand
Some of the major challenges of a rural electrification project that uses renewable energy generation are related to the users’ understanding of the technology,
the electricity service, and operation and maintenance activities.
Generally speaking, concepts such as the sustainable and rational use of solar energy, and the implications of the different charging levels of the batteries, are
not easily understood or introduced into the end-users’ daily habits. To address this, the concept of Energy Daily Allowance (EDA) was established in the Monte
The EDA makes the demand control more intelligent and flexible by introducing the concept that the energy available to each user is caped at an agreed maximum.
This ensures that the plant operates within its rated design and there will be no blackouts or unforeseen increases in operating costs. Also, higher back-up diesel fuel
consumption and components like batteries and inverters operate within their specified range, to increase efficiency and lifetime. This limit is, nevertheless, flexible
according to the plant’s condition and on very sunny days users are encouraged to make use of the surplus generation at no extra cost.
In the initial phase of the project, the designers of the facility system interviewed users to access their energy needs and their willingness to pay the 24-hour service.
This ensured that the community felt involved, as each family chose to contract the EDA monthly fee that better fit them. It also allowed technicians to understand in
detail what would be the best technical solution for the village.
Trama TecnoAmbiental, one of the companies behind this project, has used the EDA concept in other rural electrification projects in different cultures and parts of the
world and it has been well accepted because it responds to users’ needs accurately, guides them through the management of energy use, and also establishes a
fixed monthly energy budget.
The implementation is done through a special type of meter (called an electricity dispenser) that permanently shows the user the available energy allowance and
includes a signal to encourage or refrain consumption, always according to the plant’s condition.
The EDA is a vital design feature, as it is the element from which the PV generator (and then all the other major system components) is sized. So it is essential to
determine in a detailed and accurate way each user’s energy demand. It also estimates any future increase, according to the community’s specific social and

electricity service. Practical demonstrations were also performed, directly involving the users, who responded enthusiastically.
Importance of strong partnerships
As with any successful rural electrification project, Monte Trigo involved many partners from different parts of the world working together. In isolated communities
such as this one, the quality of the different components of the system gains new importance, so it is essential to involve the right (and experienced) companies for
each job. In this case, the project involved mainly three companies: Trama TecnoAmbiental, ATERSA and Studer Innotec.
From the first days of operation, the local authorities showed their satisfaction with the new 24-hour electricity service, as demonstrated by the visit of the President
of the Republic of Cape Verde (Dr. Jorge Carlos Fonseca) and of the European Union Ambassador in Cape Verde (Mr. Josep Coll) shortly after the project was
commissioned (see pictures 6 and 7).

Rema village in northern Ethiopia, home to the country's largest solar project
By Tsigue Shiferaw
Two years after the installation of a solar power project funded by international aid groups, villagers in northern Ethiopia say the sun's energy has turned their lives around.
Rema, 150 miles north of the capital Addis Ababa, is home to Ethiopia's largest solar project.
Here, every house in the village has electricity powered by solar lighting systems.
This is unique in Ethiopia - 80% of the population live in rural areas where only 1% of the population have access to electricity.
Lighting up the countryside has long been a challenge for African governments. Unlike houses in urban areas, villages in rural areas are often difficult to connect to the national electricity grid.
Solar power has been touted by some as the long-term solution to Africa's energy needs.
Domestic solar panels can provide cheap, clean and reliable electricity.
Light for homework
The village roofs are dotted with solar panels. One panel gives them about four lamps. The energy can also be used for radios and tape recorders.
Solar power has had a significant impact on the lives of people living here.
Elfenesh Tefera, 40, enjoys solar energy at home with her 50-year-old farmer husband Aseged Hailemariam.
"Our kids can do their homework at night now, because there is light. They are very happy," says Ms Tefera.
"We've had solar energy for over a year now. We're very happy because we're saving money. Altogether we have eight children, and for our kids at school the solar energy is great."
Her husband adds: "We're taking care of the panels so that we don't have to spend money replacing them."
A local bar has increased its turnover because of solar energy. With lamps running on solar energy, people stay in the bar after darkness falls.
Cold beer is in high demand in Rema - the bar's solar-powered fridge has made it available.
Hirut Kebede, a 25-year old bar worker, says solar panels have changed her life.
"I don't have to struggle with smoke [from the gas lamps] any more. Before we used gas lamps, we had to keep bottles cold by putting them in the sand," she said.
"Now we have more customers and compared to before I sell a lot more than I used to."
Samson Tsegaye, the country director of the Solar Energy Foundation in Ethiopia, says there are currently 300 requests for new solar home systems in Rema.
There are currently 2,100 solar home systems in the village.
Because of its solar power, Rema has become attractive to people from other areas. Paraffin for lamps is often hard to find in rural areas. As a result, newcomers are settling in and building new houses in the village.
A solar technician training school has been set up in Rema where students from technical schools are trained to manage solar energy.
There are currently 33 solar energy technicians who have been trained at the school in Rema, all working in different parts of Ethiopia.
"People are sometimes suspicious of energy coming from the sun," says Mr Tsegaye.
"Some say that it is the devil's work. It was difficult for them to understand at the beginning. But when they have light in their homes, they are really happy.
"They are 24-hour light users, and that is better than the big cities in this country."
The core technology is really just smart metering. You can meter each consumer in real-time every hour. You allow for pre-payment. You can allow for
time-of-day pricing. You can optimize the storage needed for demand and supply management. Ironically, everything we are doing in Shared Solar is
what the developed world wants to do. It is a smart grid with real time measurement and control.
Modi said there were two keys to the success of Shared Solar. Pay-as-you-go amounts as little as 50 cents give poor people flexibility in purchases. And the
metering technology has helped keep costs low. Modi said he’s developing Shared Solar systems for parts of Haiti and other countries. Modi said:
We hope that Shared Solar is one additional tool in the tool kit to bring electricity to the poor and to the 1.4 billion who do not currently have electricity.

An off-grid micro-solar solution to lighting africa
Wednesday, 16 January 2013 12:00:00
Half a billion people in rural Africa live ‘off grid’ with no access to electricity. Yet hand held solar products are proving to be the epicentre of a solar revolution that
will provide power to the millions currently dependent on dangerous, toxic and expensive kerosene lamps. At SolarAid we are driving forward a new sustainable
solar light market in East Africa through our social enterprise SunnyMoney.
Solar energy is nothing new. The first PV-powered satellite was launched in 1958 and solar in industry began to take-off in the 1970s. However, it’s only recently
that this technology has reached the developing world - despite the fact that Africa is one of the sunniest places on earth! The construction of huge energy farms in
the deserts of Egypt, Tunisia and Morocco are examples of how renewable energy supplies are beginning to provide power on scale.
But the biggest energy crisis in Africa is that 85% of the population don’t have access to electricity. The majority of the population live rurally and far from the nearest
electricity pylon, so for these people, solar farms that feed into a national electricity grid are meaningless. As a result, schools, clinics and businesses across the
continent are reliant on kerosene, an expensive fuel that burns, damages health and emits 260 tonnes of carbon dioxide into the air each year. So how do we get
safe, clean, cheap energy to the 70% of the African population that live rurally? At SolarAid we believe that off grid micro-solar products provide the perfect solution.
Micro-solar – or pico-solar - lights are compact all-in-one systems with a battery that can be charged throughout the day and power LED bulbs to provide light at
night. They are portable and range from hand-held products to larger systems that power strip lights and charge mobile phones. But the key is that they are all
off-grid, and offer a turn-key solution – no specialist installation, no specialist knowledge to use. They can be taken home, used in schools, shops, clinics or
whilst on the move. So long as the sun shines by day they are reliable at night, providing power to the millions of people who were previously disadvantaged by
their distance from the national grid.
We’re thrilled to be exhibiting at EcoBuild this year and will be creating our very own dark sensory stand, so that visitors can experience the pitch darkness of a
rural African village at night. To see by smoky kerosene, and then see the brilliant light that comes – for free - from these incredible micro-solar lights! We’ll also
be telling visitors how we’re getting this new technology into the hands of the people who need them most – those living furthest from the grid. With over 250,000
lights sold so far, SunnyMoney is proving the market potential for off grid energy solutions in Africa.
The energy crisis in the world’s sunniest continent causes huge barriers to infrastructural development and the alleviation of poverty. But micro-solar presents an
exciting opportunity to revolutionise the way we think about energy and to realise the potential for renewable solutions in the developing world. We’ve made it our
pop over for a chat – and a taste of Africa - at Ecobuild 2013.

A very important concept for kenya to consider
As Kenya develop Solar PV it is important that this development is truly Sustainable. The “Resource Ownership” concept could enable long term Sustainable Energy for the Country and not just exploited by quick buck companies. - a concept developed by Alan.J.Brewer MSc. over 18 years of PSECC’s work - a concept whereby a Province or District can receive extra funding from Renewable Energy generation by owning such things as Solar Farms & Wind turbines. The revenue will come from the Feed-In-Tariff (FIT) paid per KW generated $millions.. GOVERNMENT OWN THE RESOURCES WITHIN YOUR BOUNDARY, PSECC-KENYA can assist in raising all funding required for such development as Solar Farms and Wind Turbines to be owned by the Government. After Kenyalught Trial and phase one, two and three then Any costs associated with a Solar Farm or Wind Turbines are paid back from the FIT so there is no requirement for funding or cash outlay from Governments - PSECC supply Energy Savings & Resource Ownership loans..

A shiny silver robot zips along a track at a county jail in Dublin, California, and stops beside a set of solar panels propped up by a giant arm. The robot latches onto the base of the arm and turns it slowly, tilting the face of the panels like flowers to the sun. By angling the solar panels just so, the robot helps the panels catch more rays and produce more energy.
This robot, about the size of a microwave oven, is the brainchild of QBotix, a three-year-old company based in Silicon Valley that unveiled its creation last year. While tilting solar panels to track the sun's movement isn't a new concept, QBotix has come up with a novel approach that makes use of advances in robotics technology made over the past two decades. If the idea proves successful, it could lead to cheaper renewable energy and more efficient use of land for big solar installations.
Such innovations are important if solar electricity is to achieve costs comparable to power generated by fossil fuels such as coal and natural gas. And in a time when many solar plants are being built or planned for remote desert regions, where sunlight and broad swaths of undeveloped land are abundant, robotics offer a way to minimize the need for on-site workers to clean, repair and monitor solar panels and tracking equipment.
Construction of a large-scale solar power plant today typically requires armies of workers to dig ditches, pour concrete, remove trees, weld beams, and distribute materials, among other tasks. Once a project gets up and running, plant operators usually employ people to clean the panels using a hose and giant squeegee, or heavy machinery equipped with a mechanical arm for spraying and wiping. Other workers are needed to repair or replace problematic panels and parts, and solar plant operators sometimes hire pilots to fly over their arrays and snap infrared images to spot cracks, short-circuits, and other malfunctions that cause a panel to heat up. Tilting solar panels to track the sun is accomplished, if at all, by means of hundreds of costly motors and tons of steel.
QBotix's design, deployed at five pilot sites in California, Arizona and Japan, sends robots zipping along an elevated monorail constructed alongside rows of solar panels. Each battery-powered bot is programmed to adjust more than one thousand panels in a carefully choreographed sequence, tilting each panel in its assigned flock by 10 degrees every 40 minutes to keep pace with the sun’s arc. When its battery charge runs low, the robot maneuvers itself to a charging point atop the monorail, and plugs in.
"You want to produce as much as energy from the solar panels as possible because that energy is your revenue," says Wasiq Bokhari, founder and CEO of QBotix. Utilities are often willing to pay a premium for renewable power delivered during times of high demand, such as the mid-afternoon, in large part because of ambitious renewable energy mandates by state or local governments. These efforts to reduce carbon emissions have fueled a boom in solar plant development, particularly in western states such as California, where utilities must increase the amount of renewable electricity in their supplies to 33 percent by 2020.
In a conventional solar farm, panels in the Northern Hemisphere are permanently positioned to face south (in the Southern Angle, north-facing panels capture more sun). But with this design, known as “fixed-tilt,” panels face the sun directly for only a few hours each day.
To squeeze more electricity out of each panel, large solar project developers in recent years have begun adding a system of motors, sensors, and other gear to the steel structure that props up each solar panel. This system, called a tracker, helps to increase energy output by automatically rotating panels to keep them oriented to the sun’s rays.
