Battery Storage

Why Invest in Battery Storage ?

Solar panels generate clean electricity during the day – but without a battery, much of this power goes unused. A battery storage system captures that surplus energy and makes it available when you need it most, whether that’s in the evening, overnight, or during a power cut.

With a smart solar battery, you can:

Cut Your Energy Bills

Reduce reliance on expensive grid electricity.

Increase Self-Consumption

Use up to 90% of the power your solar panels produce.

Stay Powered During Outages

Enjoy backup power when the grid goes down.

Make the Most of Smart Export Guarantee (SEG)

Earn money by exporting excess energy back to the grid.

Reduce Your Carbon Footprint

Store clean, renewable energy instead of relying on fossil fuels.

Earn Money by Exporting Extra Solar Energy

With a battery storage system, you can make the most of your solar energy – and even get paid for what you don’t use. Thanks to the Smart Export Guarantee (SEG), UK homeowners and businesses can sell surplus electricity back to the grid.

How it works

Your solar panels generate clean energy.

Any excess is stored in your battery for later use.

If your battery is full, additional energy is exported to the National Grid.

Your energy supplier pays you for each unit exported under the SEG tariff.

Benefits of SEG with Battery Storage

Reduce payback time on your solar + battery system.

Generate an additional income stream from your renewable energy.

Support the UK’s transition to a cleaner, greener grid.

With start solar, our experts help you choose the right battery setup and ensure your system is fully compliant to take advantage of SEG.
