Accordingly, four rotary conductor tubes, each with diameter of 30 mm, length of 1200 mm, and thickness of 0.5 mm, are considered in the flat plate solar collector. Each such light tube rotates very slowly by using high-conductivity lubricants in contact sections between the tubes and the absorber plate.
In an area that produces an average level of solar energy, the amount of energy a flat plate solar collector generates equates to around one square foot panel generating one gallon of one day's hot water.

The flat plate collector is a box covered with glass or plastic and having a metal absorber plate at the bottom. Glass or coatings on absorption plates help passive solar hot water heater to better absorb and maintain heat. There are many different types of use of these solar collectors, but they are all built with the same basic premises in mind.
It is a special heat exchanger, in which the working substance exchanges heat with the long-distance sun.
