CW Electrical CW Electrical
For pre-2015 FiT solar homes

You’re giving
half your solar
away for free.

Your Feed-in Tariff pays you for deemed export, a fixed 50%, whether you export it or not. So the sunshine your home doesn’t use right now just spills onto the grid, earning you nothing. A battery keeps it. And your FiT payments don’t change by a single penny.

Your Feed-in Tariff doesn’t change. At all.

FiT pays you for 50% deemed export , a fixed amount based on what you generate, regardless of what you actually send to the grid. Use more at home and you still get paid the same.

The bit everyone worries about

Adding a battery won’t reduce your Feed-in Tariff.

This is the question we get most, and the answer is the best part. Because your export is deemed (estimated at a flat 50% of generation), Ofgem pays you the same regardless of what actually leaves your house. Self-consume more, export less, your cheque stays identical.

There’s a simple notification to your FiT licensee when a battery is added. We handle that paperwork for you, so nothing about your existing agreement is put at risk.
