Many homeowners in North London already have solar panels, but with rising energy use (EVs, home offices, heating), they often ask: “Can I add more panels to my existing system?”
The good news is — in most cases, yes. But there are a few important things to consider.
⚡ Check Your Inverter Size
Your inverter has a maximum capacity. For example:
- A 3kW inverter may already be maxed out.
- A 5kW inverter might have space for a few extra panels.
If it’s too small, you may need to upgrade your inverter to add more panels.
🔋 Adding Battery Storage
If you didn’t install a battery with your original system, now’s the perfect time. A battery lets you:
- Store more daytime energy
- Use solar power in the evenings
- Cut reliance on the grid by up to 85%
🛠 MCS Certification & DNO Approval
To expand your system, you’ll need:
- MCS-certified installers (like Keenan Solar)
- Approval from the DNO (Distribution Network Operator) if adding more capacity
This ensures your system remains compliant and eligible for Smart Export Guarantee (SEG) payments.
📊 Example – Finchley, North London
- Original System: 10 panels (2.8kW) installed in 2017
- Upgrade: +6 panels (2.6kW) + 10kWh battery
- Result: Annual bill reduced from £1,600 → £750, with grid reliance down to 20%
