The solar photovoltaic system is a system for converting light energy into electric energy, which utilizes solar energy to generate electricity, and the large-scale solar photovoltaic system is generally installed in natural environments such as mountainous areas, deserts or gobi with rich solar energy resources so as to obtain larger electric energy output.
However, in natural environment, pollutants such as dust, wind sand and the like can be adhered to the surface of the solar cell sheet along with the accumulation of time, and the effective conversion of solar energy by the solar cell can be influenced.
In addition, the temperature of the solar cell gradually increases with the increase of solar radiation, and in a solar photovoltaic system, parameters such as open-circuit voltage, short-circuit current and peak power of the solar cell change with the change of temperature. The method comprises the following steps:
the open-circuit voltage of the single solar cell is reduced along with the rise of the temperature, the voltage temperature coefficient is- (2.0-2.2) mv/DEG C, namely, the open-circuit voltage of the single solar cell is reduced by 2.0-2.2 mv when the temperature rises by 1 ℃;
the short-circuit current of the solar cell slightly rises along with the rise of the temperature;
the peak power of the solar cell decreases (directly affects the efficiency) with the increase of the temperature, i.e. the loss rate of the peak power of the solar cell is about 0.35-0.45% for every 1 ℃ increase of the temperature, for example: the output power of the silicon solar cell working at 20 ℃ is 20% higher than that of the silicon solar cell working at 70 ℃.
Therefore, when the silicon solar cell works at an overhigh temperature, the open-circuit voltage is greatly reduced along with the rise of the temperature, and meanwhile, the serious deviation of a charging working point is caused, so that the system is easily damaged due to insufficient charging; the output power of the silicon solar cell is greatly reduced along with the rise of the temperature, so that the solar cell module cannot fully exert the maximum performance.
For the reasons mentioned above, in order to reduce the influence of the over-high temperature on the solar photovoltaic system, when people use the solar cell modules to form a solar energy square matrix (commonly called system design) in series-parallel connection, the number of the solar cell modules is increased properly according to different use environments to compensate the voltage loss and the power loss caused by the rise of the temperature, but the influence of the rise of the temperature on the system cannot be fundamentally solved by adopting the technical scheme.
