How big can a pv plant be?

When the question arises “How big can a pv plant be built”, the answer in this case is just: The sky is the limit!  A module surface of 6-8 m² corresponds a performance of a plant of 1 kWp (kilowatt=peak= excellent performance), which produces electricity as  south focus and module decline between 800 kWh and about 1.000 kWh per year. Who wants to install his/her own pv plant on the rooftop for long-term production of electricity, can calculate that. The average power usage per year in a household of four persons amounts to environ 3.500 kWh.

This electricity requirement can be covered with a plant of 4,5 kWp (environ 30 – 35 m²). In this case, it is to be considered that the electricity requirement is all year constant but the production in the winter months is clearly smaller compared with the summer months.
