Is my roof suitable for a solar electric system?

Photovoltaic systems can be installed in all locations with sufficient solar radiation. Accordingly, many roof areas can be used. The ideal conditions for in Central Europe, e. g. Germany, are an inclination of 30 ° and south orientation without shading. A horizontal deviation to the southwest / southeast or slopes between 25° and 60° reduce the energy yield slightly. Stronger shading through trees or neighboring houses should be avoided. In order to achieve the highest possible self-consumption rates, depending on the consumption patterns, east and west orientations may also make sense, as here the production maximum is generated before and in the afternoon.
