Abstract
Description
Technical field:
[0001] The invention relates to a solar energy application technology, in particular to a secondary reflection hemispherical surface daylighting solar water heating power generation device which utilizes the principle of concentrating light on a rotating paraboloid to receive solar energy. receiving efficiency. Background technique:
[0002] Solar energy is a kind of clean energy, inexhaustible and inexhaustible, and will not cause environmental pollution. Nowadays, whether in coastal cities or inland cities, solar energy products are increasingly entering people's field of vision. Solar street lights, solar lawn lights, solar garden lights, solar corridor lights, bus station lights, traffic lights, etc., all kinds of solar water heaters have also approached thousands of households. However, most of these solar products do not have the function of concentrating light, resulting in low utilization of solar energy. If the light intensity on the surface of th...
