How Much Do Solar Panels Cost in the UK in 2026?

Considering solar panels for your home? The price depends on your roof, electricity use, equipment and whether you want battery storage. This guide explains what goes into a UK solar quotation and what homeowners in Dorset and Hampshire should look for.

How much do solar panels cost in 2026?

As a broad planning guide, a straightforward domestic solar-only installation can cost several thousand pounds, while a solar-and-battery package commonly costs more. There is no single reliable price for every property: panel count, inverter size, battery capacity, roof access, scaffolding and electrical work all affect the final quote. Rather than rely on a generic online figure, ask for a site-specific design and a fully itemised quotation.

What affects the installation price?

The biggest factors are the number and output of panels, roof type and condition, access requirements, scaffolding, inverter specification, cable routes and any electrical upgrades. A bungalow with a simple roof may have different installation costs from a three-storey house or a property with multiple roof faces.

Should you add a home battery?

A battery stores some of the electricity generated during the day for use later. It can be particularly useful if your household uses more electricity in the evenings. The right capacity depends on your daily consumption, solar generation, tariff and budget. Battery storage adds to the initial cost, so compare the expected benefit against that extra investment.

How much could you save?

Savings depend on how much solar electricity you use yourself, your import and export tariff, seasonal generation and household consumption. A trustworthy proposal should explain its assumptions rather than promise a fixed payback period. Your actual results may differ from estimates.

Are solar panels subject to VAT?

Qualifying installations of solar panels and certain energy-saving materials in UK residential properties can benefit from a zero rate of VAT under current rules. Eligibility and the treatment of individual works should be confirmed for your particular installation.

What should a solar quote include?

Ask for the panel and inverter models, battery specification if applicable, proposed roof layout, installation and access costs, electrical protection, any required network notification or approval, warranties, certification and an explanation of estimated generation. Check the installer's current accreditation and what it covers.
