The characteristics of swimming pool heating system: swimming pool is a large-scale water system, the energy consumption of swimming pool mainly comes from pool water heat exchange and hot water for shower. It is characterized by a large volume of water, ranging from tens to hundreds of tons, but the required heating temperature of the water body is low. Hot water can be recycled without discharging, as long as the temperature drops a few degrees Celsius daily. As the water is large, it is necessary to install enough solar panels to install solar collectors. We also need to consider a series of factors, such as beauty, site structure, load bearing, wind resistance and so on.

A solar cell is a device that responds to light and converts light energy into electricity. There are many kinds of materials that can produce photovoltaic effect, such as monocrystalline silicon, polycrystalline silicon, amorphous silicon, gallium arsenide, selenium, indium and copper. Their power generation principles are basically the same. Now we take crystalline silicon as an example to describe the process of optical power generation. P type crystalline silicon can obtain N type silicon by doping phosphorus and form P-N junction.
