Solar cookers are cheap, simple, and easy to maintain. By harnessing the abundant power of the sun, solar cookers provide a measure of independence to those who use them.

There are three basic types of solar cookers – box cookers, which cook at moderate to high temperatures and can accommodate multiple pots; curved concentrator cookers, which cook at high temperatures, making them ideal for large-scale cooking; and panel cookers, which incorporate elements of box and parabolic cookers, making them simple and relatively inexpensive to buy or produce.
