Question

in solar still it can absorb both types of radiation​

Answer 1

Answer:

Sunlight energy that reaches the ground is around 4% ultraviolet, 43% visible light, and 53% infrared. Solar panels mostly convert visible light into electrical energy, and they also can make use of almost half the infrared energy. But solar panels only use a small portion of ultraviolet.

Answer 2

This chapter presents an overview of the solar still. The solar still can be effectively used to obtain sufficient quantities of good water from salt water in regions where the insulation of solar energy is high. A square foot of still area can produce approximately 1/2 to 3/4 lb of distilled water per day. The only disadvantage is the large amount of space needed. The solar still consists essentially of a plastic or glass roof tray to hold water, a galvanized steel gutter for collecting distilled water, and concrete or brick side and end walls. The size is dependent on the quantity of water required. The ideal orientation is facing the equator. The water to be distilled is run down in a slow steady stream at the high end and a small overflow at the low end carries away the remaining salts, preventing crystallization. In a hot, dry climate, the depth of water evaporated is about 1/8′′ per day; the depth of water in the tray should be between 1/2′′ and 1′′.
