# Photovoltaics - Calculate Power per Size

Converter for the power of one and multiple photovoltaic modules and for the power per area. At the first calculator **Module Power**, the power of one and multiple modules can be extrapolated. Just enter the number of modules (20 is preset) and one nominal power, the other nominal power will be calculated. At **Area**, length and width of e.g. one photovoltaic module can be entered, to calculate the area, which can be output as *Area 1* or *Area 2*. **Area Power** is calculated as power per area, here three values have to be entered to calculate the fourth value.

Example: if one module has a nominal power of 185 Wp, then a photovoltaic system of 32 modules has a nominal power of 5.92 kWp. At a length with a gap of 160 centimeters and a width with a gap of 83 centimeters, the required area of one module is 1.328 square meters. At 185 Wp per module, for a 10 kWp system, an area of almost 72 square meters is needed.
