Solar Cooking

Since the people with the most need for a solar cooker often have the least money, special arrangements, such as microcredit must be made to allow these people to purchase a solar cooker in a way that works for them.

Revolving Credit[]

Sun Ovens International (SOI)[]

Unfortunately, making a solar appliance women will use for the majority of their cooking involves cost. Haiti is the poorest country in the Western Hemisphere, with 80% of the population living under the poverty line and 54% in abject poverty. SOI’s research indicated that regardless of the cost of a solar cooker, the majority of Haitians could not afford to purchase one. To address this issue, a revolving loan fund was established to enable women to obtain a Sun Oven and pay for it over time using money otherwise spent to buy charcoal.

An average family spends $2.30 (U.S.) per week to purchase charcoal. A Sun Oven can be used for 70% of their cooking and will save an average of $1.61 a week in charcoal expenditures. Weekly payments are set at $ .97 (60% of the savings); the remaining $ .64 per week creates an incentive to solar cook and takes money that literally was going up in smoke, distributing it through the local economy.

Initially, the challenge of implementing this system was that women in Haiti live very much one day at a time and even though they saved a high percentage of their income by using a Global Sun Oven, they rarely had a long enough view to understand that they were saving money. To overcome this problem, cardboard solar panel cookers were introduced. Women received 3 days of training centered around the construction of a cardboard solar panel cooker, the principals and concepts of solar cooking, and the frailty of the Haitian environment. The training occurs over lunchtime, and the first two days, Haitian foods are cooked in Sun Ovens and served for lunch. On the third day, a solar potluck is held. Each student prepares food in their own cardboard cooker and shares it with fellow trainees.

As part of the training, participants receive a log allowing them to document the use of their cardboard cooker and the amount of money they saved by not using charcoal. Participants who use their solar panel cooker on sunny days, for 90 days or longer, can use their log as a down payment on a Sun Oven. The Sun Ovens cook food much faster and can be used to cook the evening meals. After 90 days of documenting the use of the cardboard cooker, women have a much better understanding of the financial benefits of cooking with the sun and are eager to agree to a payment plan to obtain a Sun Oven.[1]

Solar Connect Association[]

The Solar Connect Association (SCA) employs a revolving Fund: Clients can buy on credit and SCA uses the revolving fund to pay itself. The client refunds the debt to the revolving fund. Women marketers are critical because they offer surety on behalf of the client as they are often known to each other and live in same locations. From 2012 to 2017 SCA had only two people default on the solar cooker loan. They considered that a donation. In principle, however, SCA has moved away from solar cooker donations because it is not sustainable in business terms. But subsidies do work.


Solar Circle reports: We've tried selling solar ovens at many different price points, all heavily subsidized, but were having very limited success. Now, our ovens disappear into homes as soon as they are built. Why? Instead of selling the ovens, we recruit communities into barter programs - they perform community service in return for an oven. The community chooses the project and the recipient, so they are happy to participate. They have built more than a dozen homes for old, blind, widowed, and ill people. They've dug latrines, provided care for people with HIV/AIDS and helped orphans. The ovens have become very popular currency!
