6kWp is the power plant size based on net metering, so
that the power demand of the user is satisfied as much
as possible. we derive the value of the solar radiation on a horizontal surface, which is estimated 1307kWh/m2. With the given tilt angle and orientation, a correction factor of 1.07. Assuming an efficiency of the plant components equal to 0.8, the expected power production per year results:
