Solar energy photovoltaic system is the system that a kind of a kind of light energy source of utilizing solar energy to generate electricity changes into electric energy, the large solar photovoltaic system generally all is mounted in the relatively abundanter natural environments such as mountain area, desert or Gobi desert of solar energy resources, so that obtain bigger electric energy output.

But in natural environment, along with the accumulation of time, pollutants such as dust, dust storm can stick the surface of applying at solar cell piece, can influence the effective conversion of solar cell to solar energy.

In addition, the temperature of solar battery sheet is along with the increase meeting of solar radiation raises gradually, and in solar energy photovoltaic system, parameters such as the open circuit voltage of solar cell, short circuit current, peak power change with variation of temperature.Specifically:

The open circuit voltage of monomer solar cell reduces with the rising of temperature, and its voltage temperature coefficient is-(2.0~2.2) mv/ ℃ 1 ℃ of the i.e. every rising of temperature, monomer solar cell open circuit voltage reduction by 2.0~2.2mv;

The solar cell short circuit current has rising by a small margin with the rising of temperature;

The peak power of solar cell reduces (directly having influence on efficient) with the rising of temperature, it is 1 ℃ of the every rising of temperature, the peak power loss late of solar cell for example is about 0.35~0.45%.: be operated in 20 ℃ silicon solar cell, its power output is than being operated in 70 ℃ high by 20%.

Therefore, silicon solar cell be operated in excessive temperature the time, open circuit voltage declines to a great extent with the rising of temperature, the serious skew of the working point that causes simultaneously charging easily makes system's undercharge and damages; The power output of silicon solar cell also declines to a great extent with the rising of temperature, causes solar module can not give full play to maximum performance.

Owing to above-mentioned reason, in order to reduce the too high influence of temperature for solar energy photovoltaic system, people are when utilizing the solar module connection in series-parallel to form solar battery (being commonly called as system design), often according to the difference of environment for use, suitably increase solar module quantity, the loss of voltage and power loss so that compensation is caused by the rising of temperature still, adopt this technical scheme can't solve temperature at all and raise to the influence of system.
