The answer is simple, you can't cook. The reasons are as follows:
1. Solar energy is usually powered by tap water. Today, tap water is still unstable in various regions. wants to use a water purifier to purify, and you can see the problems
2. The principle of using solar energy is to use the heat of the sun to heat tap water, which itself requires a process, and the materials of solar water storage tanks and pipes , there are safety risks and toxicological uncertainties
3. Solar power is usually installed on the roof of a building or in a high location, with relatively long pipes in the middle. Such pipes have good temperature and humidity. It is a place where bacteria and viruses can breed.
Summary: The purpose of using solar energy for cooking is to saveize energy, but a full analysis is not worth it.
