Why is it successful?
The cooking time is fast, like traditional stovetops. High temperatures (120–230 °C) allow for food to be fried, grilled, and boiled. There is no need of collecting or buying fuelwood. With its safe design, the cooker can be used over many years. The cost is low compared to the expense one would otherwise spend on firewood and/or charcoal as cooking fuel over time.

Successful financial model
Several organisations have provided seed funding for Solar Connect Association (SCA) to promote, produce and market different types of solar cookers since 1994, which resulted to a market expansion. SCA produces different models of solar cookers, but the parabolic cooker is traded from China. SCA’s fulltime employees are mostly women and include village women marketers who are trusted in their communities. They raise awareness through demonstrations and help SCA to generate revenue from sales that covers all expenses, which is reinvested to grow the business.
