Q: How to ascertain the actual power of solar panel?
A: Judge based on the industry average level. Current industry average conversion efficiency of
solar panel ranges from 15% to 17%. And the surface solar energy is 1000W/m².
Here we can do the math:
Electrical energy converted from solar energy per square meter: 1000W/m²x15%=150W
Electrical energy converted from solar energy per square centimeter: 150W/10000=0.015W
How much electrical power can you get in 10cm²? 0.015W x10=0.15W
