A fully installed 10-panel solar system in the UK currently costs between £4,500 and £6,500. That covers everything: the panels themselves, an inverter, mounting hardware, all wiring and electrical work, and MCS certification.
One thing worth knowing upfront: residential solar installations are subject to 0% VAT in the UK. So the price you’re quoted is the price you pay. No surprises.
What Should Be in the Quote?
A properly quoted solar installation should cover panels, inverter (the device that converts solar electricity into usable AC power for your home), mounting rails and fixings, all DC and AC cabling, a generation meter, and the MCS installation certificate.
Most reputable installers also include scaffolding costs in their quote, along with notification to your Distribution Network Operator (DNO). Some include a monitoring app so you can track your generation in real time from your phone.
Be cautious of unusually low quotes. We see this more often than we’d like. If the price looks too good to be true, it usually is. Always ask for a written breakdown of what’s included and what’s not.
What Will You Actually Save?
Based on current electricity prices of around 24–28p per kWh, a 10-panel system generating 3,000–3,500 kWh per year could save you between £720 and £980 annually on your electricity bills.
On top of that, any surplus electricity you export to the grid earns you money through the Smart Export Guarantee (SEG). Export rates vary between energy suppliers, currently ranging from around 4p to 15p per kWh.
Combined savings from bill reduction and export payments typically total £700–£1,000 per year for a 10-panel household with average energy use. That’s real money.
How Long Before It Pays for Itself?
Based on a system cost of £5,500 and annual savings of £800, a typical payback period works out to around 6–7 years. Solar panels carry a 25-year performance warranty and have a lifespan of 30+ years. So you could be looking at 18–20 years of near-free electricity after the payback point.
That’s a strong return by any measure. And the savings only improve if energy prices continue to rise, as they have done over recent years. In my experience, energy bills don’t tend to go down.
What About Grants or Funding?
The ECO4 scheme offers fully funded solar and heating improvements for eligible homeowners, primarily those with lower incomes or on certain benefits. If you qualify, it’s worth exploring before paying for a system yourself.
For those who don’t qualify for grants, many installers offer finance options. You spread the cost over several years while the savings on your bills begin immediately.
The truth is, solar panels are a long-term investment rather than a short-term purchase. At today’s costs and energy prices, the financial case has never been stronger.
