The ideal addition to your Cool or Cosy solar system and sonnenBatterie.
sonnenFlat is an energy tariff for sonnenBatterie owners. Your solar system and sonnenBatterie will cover a large portion of your energy consumption but not all. SonnenFlat provides a guaranteed amount of energy and in return some of the energy you store will be used to assist in stabilising the electricity grid. This ongoing contract allows you to opt out at any time with no exit fee.
