Frequently Asked Questions

What is the typical lifespan of a solar panel?

Most modern solar panels last between 25 and 30 years, with many continuing to generate electricity beyond that period, though at reduced efficiency.

Do solar panels need regular cleaning or servicing?

Solar panels are generally low-maintenance, but occasional cleaning and checks for shading or debris help maintain performance. An annual inspection is recommended.

What are the best solar panels for UK residential use?

Panels from brands like Trina Solar, DAS Solar, and Tongwei Solar are highly regarded for UK residential use due to their efficiency, build quality, and MCS certification.

Is it worth adding a battery to a solar system?

Yes. Adding a battery allows excess solar energy to be stored for later use, helping reduce energy bills and reliance on the grid—especially beneficial with time-of-use tariffs.

How much is the UK government grant for solar panels?

Initiatives can help reduce the cost of solar panels, including the ECO4 scheme for low-income households until March 2026, local group-buying programmes like Solar Together, and regional support such as Warm Homes (especially Northern Ireland and parts of Scotland). Homeowners also benefit from the Smart Export Guarantee (SEG), which pays for surplus electricity exported to the grid, and a 0% VAT rate on solar installations valid until March 2027.

Do solar panel installations require planning permission?

Most residential solar installations do not require planning permission if they meet permitted development rules. Restrictions may apply in conservation areas or on listed buildings.

Do I Need a DNO Application for Solar Panels?

Yes, in most cases, it will be necessary to notify your local Distribution Network Operator (DNO) when installing solar panels that connect to the electricity grid.

What is the 20% rule in solar installations?

The 20% rule refers to a guideline in some local authorities where solar panels should not exceed 20% of the roof area to remain within permitted development. Check with the local planning office.
