What is a watt peak?
Watt peak is used to calculate the power of solar panels. The number of Wp indicates how much energy the solar panels can generate. The higher the number of Wp, the better the solar panels' output. These are internationally established standards. For example, you'll generate less energy in the Michigan than in the south New Mexico.
