How Much Does a Solar Panel Cost?
With over 1.5 million UK households now generating their own electricity, solar panels have become a mainstream home upgrade. But how much does a system actually cost? This guide breaks down the price of the panels, the inverter, batteries, installation and ongoing upkeep so you know exactly what to expect.
What a Typical System Costs
A typical 4kW, 10-panel system, well suited to a mid-sized home, costs somewhere between £4,000 and £12,000. The wide range reflects the choices you make on panel quality, whether you add battery storage, and the specifics of your property and installation.
Breaking Down the Hardware
The panels themselves account for roughly £2,500 to £3,500 of the cost. The inverter, which converts the energy your panels generate into usable electricity, adds another £500 to £1,000. Optional battery storage, which lets you store power for later use, ranges from £3,000 to £6,000.
Installation Costs
Installation is a separate line item on top of the hardware. Liverpool Heating can install a 4kW system for around £1,000 to £1,500, carried out by MCS and NAPIT certified engineers.
Maintenance and Insurance
Because solar panels have no moving parts, running costs are low, at around £100 to £200 per year. An annual clean is recommended to keep the panels in pristine condition and working efficiently. Cover is typically included within a standard home insurance policy, though specialist coverage may be needed if yours does not include it.
Savings and Earning From Your Panels
Over time the panels pay for themselves through reduced reliance on the national grid. On top of the savings, the Smart Export Guarantee (SEG) means that once you sign up to an SEG tariff you receive payments for any electricity you export back to the grid.
Grants and Environmental Benefits
Government support is available through the ECO4 and Home Upgrade Grant schemes, subject to specific eligibility criteria. Beyond the financial case, switching to solar significantly reduces your household's carbon footprint. Liverpool Heating holds MCS and NAPIT certifications and is a member of the Renewable Energy Consumer Code (RECC).
