Photovoltaics - Power and Energy

Calculator for the conversion of the peak power of a photovoltaic plant and the produced energy per year. The peak power has the unit Wp, watt-peak. This is the maximum power at ideal conditions. The unit for the energy per year is Wh, watt hours. The yield factor, amongst others, depends on sunshine duration and the angle to the sun.
Here can be calculated, how much energy can be expected with a plant of a certain size or, from measured values, what the yield factor of an existing plant is. Please choose the units and enter two values, the third will be calculated.

Peak power:
Energy per year:
Yield factor:

1 kW = 1000 W, 1 MW = 1000 kW, 1 GW = 1000 MW, W = watt, kW = kilowatt, MW = megawatt, GW = gigawatt

Example: a power plant with 6 kWp, producing 5700 kWh per year, has a yield factor of 950.
