Do I need permission to install a battery?

In most cases, no permission is required if the battery is AC coupled and does not interfere with the existing system, but you should check your agreement.

Will adding a battery affect my Feed-in Tariff?

No, if the battery is installed correctly as an AC-coupled system, your Feed-in Tariff payments should not be affected.

Can I modify my existing solar inverter?

No, the inverter is part of the system owned by A Shade Greener and must not be modified.

Can I Add a Battery to an A Shade Greener Solar System?

Q: Can I add a battery to an A Shade Greener solar system?

Yes, you can add a battery, but it must be AC coupled and must not interfere with the existing solar system, as it is still owned by a third party.

Yes — you can add a battery to an A Shade Greener solar system, but it must be AC coupled and must not interfere with the existing system.

If your solar panels were installed under A Shade Greener’s free solar scheme, you’re not alone in wondering what your options are—especially now the company has gone bust.

This guide explains exactly what you can and can’t do.

Who Owns My A Shade Greener Solar Panels?

Most A Shade Greener systems were installed under a rent-a-roof agreement, meaning:

The solar panels are not owned by the homeowner
Ownership usually sits with administrators or third-party investors
They receive the Feed-in Tariff (FiT) payments

👉 This means you cannot legally modify the solar system itself.

Can I Add a Battery to My Solar Panels?

✅ Yes — but only if it is AC coupled

You can install a battery as long as it does not connect directly to the solar system.

What is an AC-Coupled Battery?

An AC-coupled battery system:

Connects to your home’s electricity supply (consumer unit)
Stores excess solar energy after it’s been converted to AC
Operates independently of the existing solar inverter

This ensures the original system remains untouched.

Why AC Coupling Is Essential

Installing an AC-coupled battery:

✔ Keeps you compliant with your original agreement
✔ Avoids interference with A Shade Greener equipment
✔ Protects Feed-in Tariff arrangements
✔ Allows safe energy storage upgrades

What You Cannot Do

To avoid legal or technical issues, do not:

❌ Install a DC-coupled battery system
❌ Replace or modify the solar inverter
❌ Tap directly into solar panel wiring
❌ Alter any part of the owned system

Benefits of Adding a Battery

Even with these restrictions, battery storage still offers:

🔋 Use your solar energy at night
💷 Reduce your electricity bills
⚡ Increase energy independence
🌍 Make better use of renewable energy
