If 1000 modules with a rated power of 300W are installed in the photovoltaic power station, the total rated power is Pr=1000 × 0.3kW=300kW The average annual solar radiation (H) can be obtained through meteorological data, measured in kWh/ ㎡. For example, the average annual solar radiation in a certain area is 1500 kWh/㎡.
6.6.1 The prediction of the power generation of a photovoltaic power station should be based on the solar energy resources of the site, and various factors such as the design of the photovoltaic power station system, the layout of the photovoltaic array, and environmental conditions should be considered before calculation and determination.
Assuming the parameters of a certain photovoltaic power station are as follows: Rated power of photovoltaic system (Pr}): 300 kW Annual average solar radiation (H): 1500 kWh/ ㎡ Performance ratio (PR): 0.8 The annual power generation (E) is: E=300kW×1500kWh/m²×0.8 =360,000kWh 2. Actual measurement method
To estimate the power generation of a photovoltaic power station simply, you can use the annual solar utilization peak hours to calculate the station's power output. Annual peak solar utilization hours is a measure of the average number of hours of solar energy available in a region during a year. That is, the peak solar time.
