Direct marketing of solar power
According to the Renewable Energy Sources Act (EEG), PV systems from 100 kWp are required to sell surplus power directly and cannot simply feed it into the grid for a fixed feed-in tariff. You could bypass this by planning a system that is just below the threshold - but you would miss out on potential added income that you could generate through direct selling ( > Direct selling).
