Earn exclusive solar credits in summer to reduce your electricity bill in winter

Our new electricity tariff for solar panel owners upgrading their PV system with a sonnenBatterie energy storage unit

We’re proud to have partnered with sonnen, a world leading manufacturer of battery storage and member of the Shell family. This partnership offers customers with solar panels a complete battery storage solution that helps to reduce their electricity bills.

If you have solar PV panels at home, or you’re planning to install them, using a home battery to store the clean electricity generated by your panels can help you to maximise the amount of renewable energy you use at home. 

To add to this, our new Solar Storage tariff can also help you reduce your electricity bills throughout the year, lower your household’s carbon footprint and contribute to driving the UK’s clean energy transition.

What is sonnenBatterie?

The sonnenBatterie is a German engineered, cutting edge and intelligent domestic battery storage system that can help you reduce your monthly electricity bills.

When you combine your solar panels with a sonnenBatterie, you can store the solar electricity that you don’t use during the day.

It’s then available to you in the evening or at night - so you’ll use less energy from the grid and save money on your electricity bill.

Our Solar Storage tariff

Do you already have solar panels installed at home? Install a sonnenBatterie and switch to our pilot Solar Storage tariff to earn solar credits in the summer when your solar panels could be generating more solar energy than you are able to consume. This will save you money on your electricity bills in winter.

Think of it as virtually storing your energy - what you don’t use in the summer, you’ll get to use in the winter*.
