Frequently Asked Questions

1. How much do solar panels cost in the UK?

The cost varies depending on the system size, brand, and installation complexity. On average:

  • A 3-4 kW system costs between £5,000 – £8,000.
  • A 5-6 kW system costs between £8,000 – £12,000.
    Battery storage adds £3,000 – £6,000 but maximizes savings.

2. Do I need planning permission for solar panels?

Most residential solar panel installations do not require planning permission as they fall under Permitted Development Rights. However, listed buildings or properties in conservation areas may need approval.

3. How long do solar panels last?

Solar panels typically last 25-30 years with minimal degradation. Most manufacturers provide warranties for 20-25 years.

4. Can solar panels work during cloudy weather or at night?

Solar panels still generate electricity on cloudy days, but at a reduced efficiency (typically 10-25% of peak output). At night, solar panels do not generate power, but battery storage systems can store excess energy for later use.

5. What is the payback period for solar panels?

Most solar panel systems in the UK pay for themselves within 6-10 years through energy savings and Smart Export Guarantee (SEG) payments.

6. What is the Smart Export Guarantee (SEG)?

The SEG scheme allows homeowners to sell excess solar energy back to the grid, earning money on unused electricity. Rates vary by energy provider.

7. Do solar panels need maintenance?

Solar panels require minimal maintenance. Occasional cleaning and ensuring they are free from dust, debris, or snow will keep them operating efficiently. Regular inverter checks are also recommended.

8. Can I add battery storage to my solar system?

Yes! Battery storage systems allow you to store excess energy during the day and use it at night, maximizing savings and reducing reliance on the grid.

9. How do I know if my roof is suitable for solar panels?

Ideal roofs:
South-facing for maximum sunlight exposure.
East or West-facing can still generate significant power.
Minimal shading from trees or buildings.
Strong roof structure to support panel weight.

10. What happens if I move house after installing solar panels?

Solar panels increase property value and make homes more attractive to buyers. You can sell your home with the panels or, in some cases, transfer ownership of a solar lease.
