Instead of converting solar energy to electricity, solar ovens trap light particles, called photons, to generate heat. With the help of metal reflectors, which are positioned around the oven to maximize light input, photons pass through the oven’s transparent glass top and strike the interior of the insulated box.

What is the difference between a solar cooker and a solar oven?
