As we know, calculation formula of electricity power generated by PV power station is: annual electricity power generated by PV power station in theory = annual average solar radiant energy * panel total area * light-electricity conversion efficiency, actual annual electricity power generated = annual electricity power generated * actual light-electricity conversion efficiency.
However, the amount of real electricity power generated by PV power station is less because of various reasons. Here is a list of ten major factors affecting solar power generation.
1. The total solar radiant energy
2. Angle of inclination of PV array
3. The efficiency of PV components
4. Assembling loss
5. Temperature characteristic
6. Loss cause by dust
7. MPPT
8. The efficiency of controller and inverter
9. The generation capacity of inverter in weak light
10. Circuit loss
