E.ON has announced it is offering its customers the chance to store their own solar power, without having to install batteries.
The energy supplier will allow households to store unlimited amounts of self-generated electricity on virtual accounts after feeding the energy back to the company.
This means they can save up an electricity credit balance for the winter during favourable conditions and then withdraw this power at a later date when it is most needed.
E.ON says the system means customers can save the purchase and installation costs of a physical storage device and don’t have to worry about maintenance.
It will initially be offering the product in Germany and Italy.
E.ON Board Member Karsten Wildberger said: “With the E.ON SolarCloud, we enable our customers to create their own personal energy world, freely and completely independent.
“The cloud solution also opens up new possibilities for owners of heat pumps or electric cars.”
