For the past 20 years, the Solar Electric Light Fund has worked to deliver solar power to rural villages in Africa, Asia, and Latin America by facilitating a new generation of “whole village” solar electrification projects.  In many of the countries in which SELF works, there is no other organization undertaking a similar, independent role in providing power to villages without existing resources. Our belief is that energy is a human right, and that without energy, community development becomes virtually impossible.

Working with government, industry and non-governmental organization partners, SELF has built a record of successful solar electricity projects in more than 20 countries, including Benin, Bhutan, Brazil, Burundi, China, India, Indonesia, Lesotho, Navajo Nation, Nepal, Nigeria, Sri Lanka, Rwanda, Solomon Islands, South Africa, Tanzania, Uganda and Vietnam.  Specifically, we have conceived and implemented projects serving the most pressing needs of the communities we are working with. With the needs of the community in mind, we see an obvious pattern emerging across the different projects we have undertaken. 

For now, let’s call this SELF’s Solar Integrated Development Maturity Model, our 5-level framework for understanding how energy poverty can be tackled at the local level, sustainably, one village at a time. The table below outlines our model:



Solar energy powers purification pumps and filters delivering clean water to communities

Solar energy powers water pumps which enable drip irrigation for critical crops

Solar energy powers health clinics allowing use of key equipment, lighting, & vaccine refrigeration.

Solar energy powers schools to enable computers and Internet access 

Solar energy powers local entrepreneurial and community activities

Level One: Water

Without access to clean drinking water, the standard of living in rural communities is always in “crisis” mode. Having a reliable water supply is the first priority of any village and this is especially true in the semi-desert of Nigeria’s Jigawa State where there are few rivers or other sources of water on the surface of the land. Typical methods of getting water range from open wells with rope and bucket, to hand pumps, to government supplied diesel-powered pumps that work only until they break down or until villagers run out of money to buy the expensive diesel fuel.

The powerful solar-powered pumps supplied with this project are designed to run maintenance free for eight to ten years or more and are currently supplying the villages with clean, fresh water from deep wells. Because the wells are tied into a village distribution system with numerous taps, the time that families used to spend getting water has been reduced as well. More >>

In India, SELF was involved in an emergency water purification project for Tsunami survivors.  This solar-driven project also proves that at the most basic level, solar power can be harnessed to provide clean water for people without basic utilities.

Level Two: Food

Food security is a critical issue in terms of stability and socio-economic development across the developing world. In November 2007, SELF partnered with Association pour le Developpement conomique Social et Culturel de Kalalé (ADESCA) to launch a remarkable pilot project, installing an innovative solar-powered drip irrigation system to pump water for food crops. SELF engineers developed a 2.1kW solar electric power supply that provides 100% of the energy for the pumps. SELF secured seed funding for the project by emerging as a winner in the 2006 Global Development Marketplace competition, sponsored by the World Bank.

Level Three: Health
Since 2006, SELF has been working in concert with Partners In Health (PIH) to provide solar power to their hospitals in Rwanda, Lesotho, and most recently, in Haiti.

In response to the devastating earthquake that struck Port-au-Prince on January 12, 2010, SELF is accelerating its commitment to power health clinics in Haiti with Partners In Health (PIH).  We have already provided solar electricity to the clinic in Boucan Carré, Hince, and Cerca La Source, and will now speed the process of solar electrifying all 10 PIH sites in Haiti.

Level Four: Education
In 2000, SELF began a project to bring solar electricity to Myeka High School, in the Valley of a Thousand Hills, a poor, backwater region in KwaZulu, South Africa. Within the first year, the school was equipped with an overhead projector, two television sets, a VCR, a photocopier, a copy printer, and 20 computers marking the beginning of a new school experience for these youngsters. The enthusiasm in the school has been contagious throughout the teachers, students, and community. Teaching has become interactive using videos, TV programs, and overhead projectors to augment the learning experience. Students can now spend their time discussing topics and reading texts instead of hand-copying notes off the chalkboard. After receiving solar electricity at Myeka High School, not only did enrollment soar by 40%, but pass rates (the percentage of seniors who graduate with a diploma) jumped from 55% to 69%.

Then, in 2008 the Solar Electric Light Fund solar-electrified three schools in the Eastern Cape Province, the birthplace of Nelson Mandela. Funded through the generosity of the Kellogg Foundation and the JP Morgan Chase Foundation, with laptops provided by Dell Computers, two thousand students and their families now have access to reliable lighting, new computer labs and wireless Internet.

Level Five: Enterprise
In Nigeria’s Jigawa State, the power of economic transformation is captured in this footage from the CNN archives:

The solar-powered micro-enterprise buildings are the project centerpieces in each village. Each center provides electricity to 6 very small businesses that would otherwise not have access to electricity. The shared PV system, much less expensive than individual systems for each shop, allow tailors to move up from manual sewing machines to electric; barbers, from manual clippers to electric, and similar improvements in productivity for other types of businesses.

This project has introduced home lighting systems to each village. Compared to the kerosene lights that they replace, solar lighting offers a better light without the inherent fumes and fire danger of the old lamps. System users report that it is now easier for children to do their studies and home businesses are thriving under the better lighting conditions. And of course, families appreciate going about their normal activities with good lighting. With about 20 systems in each village, we have created demand and a great deal of interest in home systems. Our local partner will be able to continue electrifying houses using a micro-credit scheme where the payments for each system will be used to purchase additional systems for more homes.

One of the project villages, Wawan-rafi, has a lake nearby that is used to irrigate cash crops during the rainy season. However, many of the poorest farmers are limited in their growing ability by only being able to water their fields using a hollowed-out gourd – a slow and labor intensive process. For these farmers, we developed a cattle or person pulled cart with fold-out unbreakable solar modules powering an efficient pump that can be moved from field to field. More efficient irrigation will enable farmers to produce and sell more to provide greater income for their families.

The only source of income for most village women is the production and sale of peanut oil. Traditionally, small amounts of oil are made in a process taking great amounts of time and strenuous labor. In Wawan-rafi, we have incorporated a solar-powered oil expeller that will save time and labor while earning more income for women.

The way forward for SELF is based on this 5-level solar integrated development maturity model. We view total village development as a unified whole, combining the various needs - at every level - with our capability to deliver scalable, sustainable development projects to serve the entire community.

I've just returned from Benin, West Africa where I had a chance to see firsthand the remarkable transformation that has taken place in the villages of Dunkassa and Bessassi since the launching, less than two years ago, of SELF’s solar irrigation project in Kalalé District -- a poor, dry region in the northern part of the country.

Kalalé District consists of 44 villages (~100,000 people), none of which are connected to Benin’s electric power grid.

There is precious little rainfall during the six-month dry season that runs from November through April each year.  During this period, the land of Kalalé is parched and its people are hungry. Malnutrition is widespread, as evidenced by the many children walking around with distended bellies - a telltale sign of kwashiorkor, a condition caused largely by a lack of protein and micronutrients.

Our involvement in Benin began some three and a half years ago when I was first contacted by Dr. Mamoudou Setamou, a native of Kalalé who had received a Ph.D. in agricultural entomology from the University of Hanover in Germany.  Mamoudou, now a Professor at Texas A&M University, had just returned from a home visit to Benin, where he had participated in a meeting of Kalale’s district council to explore alternative options for electrifying Kalalé’s villages since the national grid was not likely to reach this remote part of Benin anytime in the foreseeable future.

Intuiting that solar represented a way forward for his people, Mamoudou turned to SELF for help.  After a series of discussions, it became clear that Kalalé District, with its 44 unelectrified villages, offered a great opportunity for SELF to scale its work beyond the scope of a single village to encompass an entire region.  After all, with much of Africa still without access to modern energy services, it was time to think and act boldly.

Over the next few months, we put together a plan to generate solar electricity for a wide range of end-uses—including schools, health clinics, water pumping systems, street lighting, and wireless Internet access—in each of the 44 villages that comprise Kalalé District.

In terms of priority, however, an on-the-ground needs assessment revealed that the first concern among the local communities was food security: to find a way to overcome the endemic lack of water and agricultural produce that condemns the people of Kalalé to an endless cycle of poverty and poor health, especially during the 6-month dry season.

To address this problem, we approached Professor Dov Pasternak, a leading drip irrigation expert who, for the past eight years, has been working for the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT).  While at ICRISAT, Pasternak developed what he refers to as the “Africa Market Garden” – a simple but highly effective method of using drip irrigation to grow high-value fruits and vegetables on small plots of arid land in the Sahel region of Africa.

Prior to working with SELF, Pasternak had relied upon diesel generators to power the water pumps used in his drip irrigation systems.  Needless to say, we felt that solar represented a more viable alternative, economically and environmentally.  Dov agreed to try it our way, and now with the successful launch of the first solar-powered drip irrigation systems in Benin, he has become a solar convert.  (In a white paper SELF recently put together, it is shown that the payback period for solar pumping – as compared with diesel – can be less than two years, and that's at today's diesel prices which are going up, and solar prices which are going down.)

My recent trip to Kalalé was the first time I had visited the project since its launching in November 2007.  I was accompanied by a French film crew that is going to feature SELF in an upcoming segment of "Earth from Above", a National Geographic–like program hosted by well-known French photographer Yann Arthus-Bertrand.


It was great to return to Benin and spend time with the people of Dunkassa and Bessassi, the two pilot villages where solar drip irrigation systems have been installed.  I immediately noticed a difference in the women, who have filled out since our last encounter.  Not only are the women better fed, but so are their families and the rest of the villagers who now have year-round access to a steady supply of highly nutritious fruits and vegetables.

What’s more, the women are earning an extra $7.50 per week from the sale of fresh produce at the local market.  I was there on market day, and was delighted to see the women march off proudly into town with their baskets filled to the brim with leafy green vegetables.

So not only has nutrition improved in Dunkassa and Bessassi, but income levels also have risen — income which will help pay for school fees, medical treatment, and overall economic development.  Indeed, the women are already starting to think about other types of income-generating schemes that can be launched in the villages.  It appears their entrepreneurial spirit has been kindled!

Phase II of this project in Benin, scheduled for launch next year, will involve the “whole-village” electrification of Dunkassa and Bessassi, whereby solar electric systems will generate power for the school, health clinic, homes, street lighting, community center, and a WiFi network in each of the pilot villages.  We’re also planning to install additional solar pumps that will provide fresh drinking water to the residents of Dunkassa and Bessassi.

While much remains to be done, we’ve gotten off to a promising start in Benin.  The tandem use of solar energy and drip irrigation can be replicated in many other parts of sub-Saharan Africa that are poor in water resources but rich in sunlight. 

What’s particularly exciting is the fact that in this one project we now have a sustainable model that is simultaneously combating climate change, improving food security, supplying clean water, alleviating poverty, and empowering women.
