If you installed solar panels under the Feed-in Tariff (FIT) scheme, you’re already enjoying the benefits of generating your own renewable energy while receiving payments for the electricity you produce. But what if you want to add more solar panels to your home? Can you still benefit from FIT payments? And what other options do you have?
At Sunlit Solar, we specialise in helping Somerset homeowners expand their solar capacity the right way, ensuring compliance with FIT agreements while maximising long-term energy savings.
What is the Feed-in Tariff (FIT) Scheme?
The Feed-in Tariff (FIT) scheme was a UK government initiative designed to encourage renewable energy adoption by offering financial incentives to homeowners who installed solar photovoltaic (PV) systems. Although the scheme is now closed to new applicants, those who signed up before its closure continue to receive:
✅ Generation Payments – Paid per unit of electricity produced, even if used on-site.
✅ Export Payments – Paid for surplus electricity sent to the grid, typically estimated at 50% of total generation unless an export meter is installed.
But how does adding extra solar panels impact your existing FIT payments?
Can I Add More Solar Panels to My Existing FIT System?
The short answer: Yes, but the new panels will not qualify for FIT payments.
Here’s what you need to know before expanding your system:
Option 1: Metering the New System Separately
🔹 The additional panels are treated as a new system, separate from your existing FIT agreement.
🔹 Your original solar installation continues to receive FIT payments as usual.
🔹 The new system can qualify for the Smart Export Guarantee (SEG), a modern scheme where energy suppliers pay you for exported electricity.
🔹 A new inverter may be required.
Option 2: Combining the New Panels with Your Existing System
🔹 Your FIT payments remain based on the original system’s capacity.
🔹 Any extra energy generated beyond the original capacity will not qualify for FIT payments.
🔹 You must inform your FIT licensee about the system expansion.
What About Export Payments?
Many FIT participants receive deemed export payments, meaning they are paid as if they export 50% of the electricity generated, regardless of actual usage.
If you increase your solar capacity:
✔️ Your FIT export payments will stay the same unless you install an export meter.
✔️ Any additional exported energy could qualify for the Smart Export Guarantee (SEG).
What is the Smart Export Guarantee (SEG)?
Since the FIT scheme closed to new applicants, the Smart Export Guarantee (SEG) has become the alternative for earning money from solar energy exports.
🔹 Available for new solar installations or additional capacity added to existing systems.
🔹 Payments vary by supplier, so comparing SEG tariffs is crucial.
🔹 Requires an export meter to track actual surplus electricity.
Steps to Take if You Want to Expand Your Solar System
If you’re a Somerset homeowner considering adding more solar panels, follow these steps to ensure compliance and maximise your financial benefits:
✅ Notify Your FIT Licensee – Inform them of any system changes.
✅ Install a Separate Meter – This helps track the new system’s exports and qualify for SEG payments.
✅ Compare SEG Tariffs – Find the best rates for selling excess electricity to the grid.
✅ Choose High-Quality Equipment – Ensure new panels and inverters are compatible with your existing system.
