technical field

The utility model relates to a water cooling system for photovoltaic power generation, in particular to a solar panel water cooling system.

Background technique

In the practical application of photovoltaic power generation system, its power generation performance is greatly affected by natural environmental conditions, and the operating temperature of the main component of the system—solar cell module—is one of the important factors affecting the performance of photovoltaic power generation system.

At present, silicon-based solar cells are mainly put into large-scale commercial applications. The influence of temperature on silicon solar cells is mainly reflected in the changes of parameters such as open-circuit voltage, short-circuit current, and peak power of solar cells with changes in temperature. Taking a single solar cell as an example, its open circuit voltage decreases with the increase of temperature, and the voltage temperature coefficient is -(210~212)mV/°C, that is, for every 1°C increase in temperature, the open circuit voltage of a single solar cell decreases by 210~ 212mV; the short-circuit current of the solar cell increases with the increase of temperature, and the peak power of the solar cell decreases with the increase of temperature (directly affects the efficiency), that is, the peak power loss rate of the solar cell is about 1.35% to 1.45%, for example: the output power of a silicon solar cell working at 20°C is 20% higher than that at 70°C.
