Dusseldorf When Herbert Hellmann built four photovoltaic systems in Bavarian Swabia in 2016, there was one thing he didn’t want: the fixed feed-in tariff that the Renewable Energy Sources Act (EEG) guarantees for 20 years. Instead, he registered his systems with a total output of 59 kilowatts for direct marketing.
The producer has to sell the electricity fed into the public grid on the market – the grid operator does not automatically buy it. Nevertheless, a solar power producer can count on a minimum yield. This corresponds to the feed-in tariff plus a management premium of 0.4 cents per kilowatt hour to finance the marketing effort.
If the market value for solar power is below the minimum revenue in a month, the grid operator pays the difference, known as the market premium. “That was a commercial decision,” says Herbert Hellmann. “Should the electricity be worth more, I would earn more.”
