Electricity flat rate thanks to integrated solar PV and home storage units

Bavarian storage manufacturer sonnen will offer a free power flat rate to consumers that install the company’s integrated solar PV and home storage systems, sonnen announced in a press release. The flat rates will be financed with revenues the company receives from offering its customers’ storage capacity in the balancing power market, where prices are higher than in the regular markets. Up until now, sonnen only received permission for the Swiss market, but will nonetheless offer the flat rate to German customers as well, writes pv magazine in an article. The home systems are connected to the grid and each other in a virtual power plant, thus being able to provide the size and reliability needed for balancing power. Customers produce about three quarters of the electricity they need themselves and receive the rest externally, writes pv magazine.
