How Much Do Solar Panels Cost in the UK 2026

Short answer: A complete, fully-installed solar and battery system for a typical UK home costs around £8,000–£10,000 in 2026. At Evergreen Power UK, our flagship package is £7,995 fully installed – that’s ten 465W black panels (4.65 kWp), two 5.12 kWh batteries (10.24 kWh of storage), a hybrid inverter, all paperwork and full warranties. No “from” pricing, no surprises.

Below we break down exactly what drives the cost, what you should expect to be included, and the savings that follow

What goes into the price of a solar system?

When you see a solar quote, you’re paying for far more than panels on a roof. A proper installation includes

• The panels themselves: – wattage, brand and finish (all-black panels cost a little more but look far smarter).
• The inverter: – converts DC to usable AC. A *hybrid* inverter (which manages a battery too) costs more than a basic string inverter but future-proofs your system
• Battery storage: – (optional but increasingly standard) – usually the single biggest line item
• Mounting, cabling, electrical equipment, scaffolding and labour
• Certification and paperwork: – MCS certification, DNO/G99 grid notification, and the documentation you need to claim Smart Export Guarantee payments.
• Warranties: – on panels, inverter, battery and workmanship

Solar Panel Prices in the UK: 2026 ballpark

For panels alone (no battery), here’s what a fully installed system typically costs

System size	Suits	Indicative installed cost
3.5 kWp (~8–9 panels)	Smaller home, lower usage	£5,000 – £6,500
4.5 kWp (~10–12 panels)	Average 3-bed home	£6,000 – £8,000
6 kWp (~14–16 panels)	Larger home / higher usage	£8,000 – £10,500

Add a battery, and you’re typically looking at £3,500–£8,000 on top, depending on capacity, which is why an all-in package often represents better value than buying the parts separately

Our flagship package: what £7,995 actually gets you

We believe in transparent pricing, so here’s exactly what’s in our most popular system:

Evergreen Power UK £7,995, fully installed

• 10 × 465W black panels (4.65 kWp) — sleek, all-black, high-output
• 2 × 5.12 kWh batteries (10.24 kWh total storage)
• Hybrid inverter — battery-ready and smart-tariff compatible
• Full installation by our own in house engineers
• All paperwork handled — including DNO/G99 grid notification
• Full warranties on panels, inverter, battery and workmanship

This is a genuine whole-home package: enough generation to cover much of an average family’s annual electricity, plus over 10 kWh of storage to use that energy after dark or to load up on cheap off-peak power overnight

What will a system like this save you?

Savings come from two places: the grid electricity you no longer buy, and the Smart Export Guarantee (SEG) payments for surplus you export

For an average home, a 4.65 kWp system with 10.24 kWh of storage on a smart time-of-use tariff can realistically deliver combined savings and export income in the region of £600–£1,000+ a year — the upper end if you charge the battery from cheap off-peak power and shift your usage away from peak hours. On a £7,995 system, that points to a payback period of roughly 7–10 years, against panels warranted for 25 years-plus and a battery typically covered for 10.

Your figure depends on your roof, your usage and your tariff. We model your *actual* half-hourly consumption before quoting, so the number we give you is real — not a brochure best-case.

Ways to reduce the cost?

A few things work in your favour in 2026:

• 0% VAT on residential solar and battery installations — a government measure to encourage uptake, currently saving you the VAT on the whole job. (Policy can change, so confirm at the time.)
• The Smart Export Guarantee (SEG) — ongoing payments from your supplier for exported electricity, effectively reducing your net cost over time.
• Finance options — spreading the cost can mean monthly repayments that are partly or fully offset by your solar energy savings

Why the cheapest quote is rarely the best value

We’d gently warn against picking purely on the headline price. Watch for

• “From” pricing that balloons after the survey.
• Missing certification — without MCS, you can’t claim SEG payments.
• Budget inverters or batteries with short warranties or poor smart-tariff support.
• Subcontracted labour with no accountability if something goes wrong

A fair, fixed, all-inclusive price from a certified installer protects you far better than the lowest number on the page

Frequently asked questions

1. How much do solar panels cost in the UK in 2026?

A fully-installed solar system typically costs £5,000–£10,500, depending on size, with batteries adding £3,500–£8,000. Evergreen Power UK‘s flagship all-in package — 4.65 kWp of panels, 10.24 kWh of battery storage and a hybrid inverter — is £7,995 fully installed, including paperwork and warranties

2. Is it cheaper to buy solar panels and a battery together?

Usually yes. Installing them together shares the cost of scaffolding, labour and the inverter, and a hybrid inverter is designed to manage both — so an all-in package generally beats buying and fitting the parts separately

3. How long do solar panels take to pay for themselves in the UK?

Typically, 7–10 years for a well-sized system, helped by high grid prices, SEG export payments and 0% VAT. Panels are warranted for 25 years-plus, so most of their working life comes after payback

4. Do solar panel prices include installation and paperwork?

They should. A proper quote is fully installed and includes MCS certification, DNO/G99 grid notification and warranties. Evergreen Power UK’s £7,995 package includes all of this — beware “from” prices that don’t

5. Is there VAT on solar panels in the UK?

As of 2026, residential solar and battery installations attract 0% VAT under a government measure to encourage adoption. As with any policy, it’s worth confirming this is still in place when you buy
