after that the solar power plant is just for profit. but i don't calculate profit if i calculate the costs.
if you calculate the profit you calculate ((20MWh*160€)+(20MWh*30€))/40=95€ (thats because the EEG law pay 20 years 160€ and after that 30€)
now we know germany pay by law 95€ now we calculate the profit 95€-32€= 63€
solar power plant owner makes 63€ profit on solar power by LAW!
