Typically, the power of solar energy per square meter on earth is around 1,000 watts. The conversion efficiency of light energy is different depending on different materials.
Gallium arsenide cells in solar panels are currently the most efficient. most efficient and has the highest conversion efficiency. Greater than 37%
The power of one square meter is 370 watts, or 0.37 kilowatt-hour (degree) in one hour. Eight o'clock is less than 3 degrees. /p>
Ordinary commercial solar cells 13 -22%
The power of one square meter is 130-220 watts, and the power of one hour is 0.13-0.22 kilowatt hours (degree eight). hours is about 1-1.5 degrees
