Watt peak​

Each type of solar panel has a certain capacity that the solar panel can generate solar energy. A panel with an output of 480 wP we generate about 384 kWh per year. Due to various circumstances, a solar panel does not always work optimally and the sun does not always shine optimally. For this reason, there is a factor for calculating the effective output of a panel. A system of 10 solar panels does not generate 4800 kWh per year, but 3480 kWh per year. On top of this, a very hot sun does not automatically mean better generation. Even if the sun does not shine on a cloudy day, a solar panel generates energy.
