Add Battery Storage to Your Feed-in Tariff Solar

If your solar panels were installed under the UK Feed-in Tariff, you can add battery storage — when it’s done correctly.
Mr Solar specialises in FiT-safe battery upgrades that protect your income and maximise your solar use.

The Problem

Many homeowners on the Feed-in Tariff:                                                                                                 

• Export valuable solar energy for very little return

• Buy expensive electricity back in the evening

• Are told adding a battery will cancel their FiTs payments

That fear stops thousands of people upgrading — unnecessarily.

The Truth About Batteries & Feed-in Tariffs

✔ Ofgem allows battery storage to be added to Feed-in Tariff systems
✔ Your FiT payments remain unchanged
✔ The system must be designed so only solar generation is measured

When installed correctly, battery storage:

• Stores your excess solar

• Reduces grid imports

• Keeps your Feed-in Tariff fully intact

Why Experience Matters                             

Most installers today:

• Focus on new solar installs

• Don’t understand FiT-era metering

• Risk invalidating your tariff through poor design

Mr Solar specialises in older systems.
We design battery upgrades that work with your existing FiT installation — not against it.
