Abstract

The dual-carbon target has made solar photovoltaic panels widely used. But the normal operation of photovoltaic panels under extreme weather conditions is still an important issue to be solved. For large-area photovoltaic arrays, the effect of photovoltaic panels under extreme wind weather, such as typhoon, is becoming more obvious. To solve the above dilemma, this paper established the numerical simulation model of photovoltaic panels under turbulence field, and studied the displacement of the solar panels when the wind speed is over 25m/s. The results have shown that when the flow rate is 25m/s, the maximum relative pressure of the solar panel is about 70Pa, which appears on the upper right and left of the solar panel. The maximum displacement caused by the wind also appears on the same point of the solar panel, which even reached 1mm in solid surface. After this the economic analysis has also been done for PV operation and maintenance. The machine replacement rate data dropped from 5.6% to 1.7% after added the reinforced facilities. The LCOE for PV also reduced. These results can provide an important reference for the planning of solar panels and the effective operation under extreme weather conditions like typhoon in the future.
