E.ON solar panels: prices, kit and export rates (September 2026)

E.ON Next sells and installs solar panels and batteries through its installation company, using its own installers and partner firms. On 24 September 2026 its prices started at £4,995 for six AIKO 485 W panels (2.91 kWp) and £6,495 for twelve (5.82 kWp), each with a hybrid inverter ready for a battery; the six-panel price assumes a straightforward roof. Customers who buy an E.ON installation and take their electricity from E.ON Next can get a 17.5p per kWh export rate for 12 months, once per property. The twelve-panel price per kWp was below the government's average for domestic installs of that size, so the key questions are what your own quote adds and what you will earn after year one.

Everything below comes from E.ON Next's website on 24 September 2026. Solar Report has no commercial relationship with E.ON or any other supplier: we are not paid for this review.

What E.ON installs

E.ON says its batteries use lithium iron phosphate (LFP) cells and that the battery must sit fairly close to your consumer unit, usually in a cupboard, garage or utility room. It can go outside if it is sheltered and not on a south-facing wall.

E.ON solar and battery prices

Our solar battery cost guide explains what drives battery prices.

Prices include VAT, which is 0% on solar panels and batteries supplied and installed in your home until 31 March 2027 and scheduled to become 5% from 1 April 2027. Existing E.ON Next customers could take £200 off a solar-and-battery purchase or £150 off a battery with the codes on E.ON's pages.

Worked example: E.ON's prices per kWp. The twelve-panel package is £6,495 ÷ 5.82 kWp = about £1,116 per kWp; the six-panel package is £4,995 ÷ 2.91 = about £1,716 per kWp. For comparison, the Department for Energy Security and Net Zero (DESNZ) reports mean installed costs for domestic retrofit solar in 2025/26 of £1,651 per kW for 4 to 10 kW systems and £2,109 per kW for systems up to 4 kW, including VAT and excluding batteries. Both E.ON packages are below those means. They are starting prices, though, and extras such as more scaffolding, three-phase work or a battery move the final figure: compare the price on your own quote, not the headline. Our solar panel cost guide explains what a quote should include.

Export rates for E.ON customers

E.ON Next had three home export tariffs on 24 September 2026. All need a smart export meter and your consent for half-hourly readings, and all are Smart Export Guarantee tariffs, which cover Great Britain only.

E.ON pays export money once a year by default; you can ask for up to four payments a year by sending a meter photo.

Worked example: the 17.5p deal over two years. For every 1,000 kWh you export, Export Premium, which needs an E.ON installation and E.ON Next electricity supply, pays 1,000 × £0.175 = £175 in the first year. Export Premium can't be renewed, so from year two you need another tariff: Export Exclusive pays 1,000 × £0.13 = £130 if E.ON also supplies your electricity on a standard tariff, and Flex Export pays 1,000 × £0.06 = £60 if it doesn't. So judge the system on the rate you will get for most of its life, not the first-year rate. Our best export tariffs comparison shows what other suppliers pay.

E.ON's headline savings figure on its solar pages is an example with stated assumptions: 4,000 kWh of electricity use a year (Ofgem's typical figure is 2,500 kWh), a 5.1 kWh battery, the 17.5p first-year export rate and the July to September 2026 price cap. A home using less electricity, or without a battery, would save less. Use our calculator with your own usage.

Where E.ON installs and which roofs suit

E.ON said its service covered mainland UK except the Scottish islands, the Isle of Wight and Northern Ireland, and depended on local installer capacity. It fits roofs facing south, east or west with a pitch between 20° and 50°, and does not normally recommend north-facing roofs. It inspects the roof first and handles the grid connection application. A small system on one roof can take a day; most take two, plus time for scaffolding.

Paying, warranties and cancelling

Payment. E.ON's page offers three routes: pay the full amount upfront, pay in three stages (25% deposit, 50% when materials are ordered, 25% on completion), or pay through a finance company it works with, over up to three, five or ten years, subject to credit checks. E.ON's page gives the rates and a representative example. If you borrow, compare the total amount payable, not the monthly figure, and use your repayments in any payback sum.

E.ON's solar and battery terms say the 25% deposit is protected through HIES, a consumer code, up to 25% of the price or £5,000, whichever is lower. They also ask for a staged payment once your equipment is allocated to you, with the balance due within seven days of completion. MCS no longer requires installers to belong to a consumer code, so this cover comes from E.ON's own commitment to the HIES code, described in its terms. HIES's installer register listed E.ON Energy Installation Services Ltd (membership number EON/A/0184) for solar PV and battery storage on 24 September 2026, and Companies House listed the company (number 09965944) as active the same day. You can check any installer's membership on the HIES website.

Warranties. E.ON lists a 30-year panel product warranty, a 10-year battery warranty and a 2-year workmanship warranty, backed by insurance so you can claim if E.ON stops trading, and transferable free if you sell the house. Its terms say labour to replace a part under a manufacturer's warranty is not included, so ask what a battery or inverter swap would cost in year five. Octopus, for comparison, lists five years of workmanship cover; get the length in writing from any installer you consider.

Cancelling. For a contract made online or in your home, the law lets you cancel from the day you sign until 14 days after the goods are delivered, and E.ON's terms give the same 14 days from when you receive the goods. If you cancel after that but before installation, the terms say you lose your deposit and may pay E.ON's reasonable costs. Our guide to choosing a solar installer sets out your rights in full.

E.ON or an independent installer?

E.ON's twelve-panel price per kWp is low, the kit is clearly named and the first-year export rate is the highest on its list, though it needs E.ON Next supply. Against that, the workmanship warranty is two years, some work goes to partner firms, and on the staged plan 75% of the price is paid before the job is finished. Get a quote from an independent MCS-certified installer for the same kWp and battery, and compare the items in our guide to comparing solar quotes. Our comparison of solar companies sets E.ON next to Octopus, Hive and independent installers on the same criteria.

FAQ

Are E.ON solar panels any good?

E.ON fits AIKO Neostar 3S 485 W panels with a 30-year product and performance warranty, a battery-ready hybrid inverter and a named battery. Whether the installation is good depends on the survey, design and workmanship on your roof, so read the MCS generation estimate and the warranty terms before you sign.

Are E.ON solar panels worth it?

On price, E.ON's twelve-panel package worked out at about £1,116 per kWp on 24 September 2026, below the DESNZ average for domestic systems of that size. Whether it pays back depends on your electricity use, your roof and what you earn after the first year of export payments. Test your home in our calculator and compare at least one independent quote.

Can I get E.ON's 17.5p export rate if E.ON didn't install my panels?

No. Next Export Premium v3 needs a system installed by E.ON from 10 November 2025, and E.ON's solar pages say you must also buy your electricity from E.ON Next. If E.ON supplies your electricity on a standard tariff you can get 13p fixed for 12 months, and anyone can get the variable 6p rate.

Does E.ON install solar panels in Northern Ireland or Scotland?

E.ON said its service covered mainland UK, excluding the Scottish islands, the Isle of Wight and Northern Ireland. The Smart Export Guarantee also does not apply in Northern Ireland.
