How do homemade solar ovens work?
A solar oven works by catching sunlight using a reflector and reflecting it onto a black surface (we’ve used a black sheet of paper). The black surface transforms the light into heat and the upturned glass bowl traps the heat inside. It heats up just like your car does on a hot summer day.
Do solar ovens work on cloudy days?
On a partly cloudy day the SUN OVEN® can cook when the majority of solar cookers cannot. (There only needs to be enough sun to cast a shadow to use a SUN OVEN® while full sunlight is required for the others.) Most solar cookers do not get hot enough to bake bread, but if they can, full sun is required.
What shapes do solar cookers make?
Parabolic solar cookers use a parabolic-shaped reflector to direct sunlight to a small area in order to generate heat for cooking.
What is the best shape for a solar cooker?
The parabolic style tends to be more effective, reaching higher temperatures and faster cook times, but is expensive and requires frequent adjustments. The panel style cooker can be very cheap and easy to build, but often are not as effective as the other models.
What are disadvantages of solar cooker?

What does plastic wrap do in a solar oven?
The foil reflects the ray, and bounces it into the opening of the box. Once it has gone through the plastic wrap, it heats up the air that is trapped inside. The black paper absorbs the heat at the bottom of the oven, and the plastic wrap helps the heat stay inside the box to cook the food.
