What''s a good value for kWh/kWp? An overview of specific yield

The nominal power (kWp) is the power of the PV system under standardized conditions (solar irradiation of 1,000 watts per square meter at a temperature of 25 °C). This is measured in kWp (kilowatt peak). So here a 200Wp panel would produce 200Wh. The rated power is given so that solar panels can be compared.
