What Do You Know About Solar Panels?

(1) light - heat - electricity conversion method through the use of solar radiation heat generated by electricity, usually by the solar collector will be absorbed by the heat into the refrigerant, and then drive the turbine power generation. The previous process is the light - heat change process; the latter process is the heat - electricity change process, and the usual thermal power generation. Solar thermal power generation defects are low power and high cost, it is estimated that it is less than the usual fire Power station 5 to 10 times a 1000MW solar thermal power plant needs to invest 20 to 25 billion US dollars, even 1kW of the investment of 2,000 to 2,500 US dollars. Therefore, at that time only small-scale application to the occasion, and large-scale use in the economy is very cost-effective, can not compete with the usual thermal power plant or nuclear power plant.

(2) light - electricity direct change method The method is to use the photoelectric effect, the solar radiation can be directly converted into electricity, light - electricity to change the base equipment is the solar cell. Solar cells are a device that converts solar energy directly into electrical energy due to the photovoltaic effect. It is a semiconductor photodiode. When the sun shines on the photodiode, the photodiode will convert the solar energy into electrical energy. The When many batteries in series or in parallel can become a contrasting large output power of the solar cell array.
