The current application scope of solar energy is nothing but thermal energy and electrical energy
Thermal energy includes water engineering hot and heating engineering
Electric energy is so-called photovoltaic energy. electricity generation, and the solar cooker you mentioned belongs to thermal energy. In terms of engineering, solar cookers are still very impractical at present. You have to follow the movement of the sun to ensure that its reflection is focused on the stove. The altitude angle of the sun is different in spring, summer, autumn and winter, and it also needs to be adjusted back and forth. It's very laborious. Our company made a solar cooker like this but I couldn't sell it so I ended up making it. to get rid of. But you can still produce solar biogas. In the north, the rate of use of biogas is lowble in winter. It is possible to use solar hot water to pour into the biogas digester to accelerate the biogas reaction in winter.
