Shell Energy has launched a new Solar Storage tariff as part of its partnership with German battery storage system manufacturer sonnen.

Customers with solar panels installed on their homes will be able to earn solar credits in the summer, when they are generating excess power that can be exported to the grid. These credits can then be used come winter to save money on bills.

In the UK, a home will typically use about 30% of the electricity produced by their solar panels, but by combining it with a sonnenBatterie this can grow to 75% of their annual energy produced. Adding Shell’s new tariff increases this even further the company stated.

The battery will help customers store energy during the day, which they can then use in the evening and overnight to reduce their carbon footprint and their bills on a day to day basis. The Shell Solar Storage tariff then brings the same benefits over the course of the year, the company claims, allowing consumers to save up to £150 (US$188.36).

It was initially launched as a pilot by Shell Energy, with a limited number of customers trialling the system after the company had consulted with customers and found that some were concerned about the seasonal performance of solar panels.

The tariff would be suitable for 825,000 homes in the UK that already have solar panels or are considering installing them, and therefore offers huge potential to support mass solar and battery installation, Shell said.
