EON Next Solar Panels Review: Costs, Packages & Alternatives
EON Next don't make solar panels and they don't fit them either. What they sell is a wrapper: a national call centre, a finance product, and a managed handoff to a regional subcontractor who does the actual install. The kit on your roof, usually Longi or JA Solar panels with a Solis or Huawei inverter, is the same kit a local MCS firm would fit, so the real comparison is price and aftercare, not hardware.
EON Next solar panels cost from £4,995 for a 6-panel system and £6,495 for 12 panels on their published 2026 price list, with a battery from £1,900 when added at install and up to 3 years 0% APR finance. Those from-prices are genuinely competitive: a 12-panel system under £6,500 undercuts many independent quotes. But a from-price is the cheapest possible configuration. Tailored quotes climb with roof complexity, array size and battery choice, so the real question is what your final quote says, and whether a local MCS firm beats it like for like.
Quick Answer
EON Next solar panels start at £4,995 for a 6-panel system and £6,495 for 12 panels on E.ON's published price list, with a battery from £1,900 at install and up to 3 years 0% APR finance. The panels and inverter brands (Longi, JA Solar, Huawei) are the same kit independent MCS installers fit; only the install is subcontracted. From-prices assume the simplest configuration, so tailored quotes can come back higher. Get a quote from at least one local installer before you sign.

What is EON Next Solar?
EON Next is the retail energy brand of E.ON UK, one of the “Big Six” energy suppliers. E.ON rebranded its UK retail operations to EON Next in 2022, combining its energy supply business with solar panel installations, battery storage, heat pumps, and EV chargers under one roof. EON Next doesn't manufacture the panels. They source equipment from established makers (typically Longi, JA Solar, or similar tier-one brands) and use a network of subcontracted installers to carry out the work.
The company
EON Next is the UK retail arm of E.ON SE, a major German energy company. E.ON serves approximately 5 million UK customers. The solar and home energy division operates alongside their electricity and gas supply business.
What they offer
Solar panel systems (typically 3 to 5 kW), battery storage add-ons, smart export tariffs, home surveys, installation by MCS-certified subcontractors, and ongoing monitoring via the EON Next app.
How it works
You request a quote online, EON Next arranges a home survey (remote or in-person), you receive a system design and price, and their subcontracted installers carry out the work. The process typically takes 6 to 10 weeks from enquiry to installation.
What buyers usually miss about EON Next solar
- EON Next does not manufacture solar panels. They source tier-one equipment from established brands
- Installation is carried out by subcontracted MCS-certified installers, not EON employees
- You do not need to be an existing EON Next energy customer to buy their solar panels
- EON Next offers finance options, including interest-free credit on some packages
- Smart tariff benefits (e.g. EON Next Solar Export) are available to EON energy customers
- All installations include a workmanship warranty alongside manufacturer panel and inverter warranties
EON Next solar panel packages (2026)
EON Next offers a range of solar packages designed for different property sizes and energy needs. Packages typically include solar panels, a hybrid or standard inverter, mounting hardware, scaffolding, all electrical work, DNO notification, and MCS certification. Battery storage is available as an add-on or as part of a combined package. If you want a specific battery rather than EON’s default, an independent installer can fit brands like Tesla Powerwall 3 or the all-in-one Sigenergy SigenStor with built-in EV charging.
| Package | System Size | Typical Panels | Battery Option | Estimated Cost |
|---|---|---|---|---|
| 6-panel system | ~2.5 kW | 6 panels | Optional add-on | From £4,995 (published) |
| 12-panel system | ~5 kW | 12 panels | Optional add-on | From £6,495 (published) |
| Battery added at install | – | – | Sunsynk as standard | From £1,900 (published) |
| Battery Only (retrofit) | – | – | Sunsynk Elite or Tesla Powerwall 3 | From £3,995 (Powerwall 3 from £7,795) |
What’s included
- Tier-one solar panels (typically Longi, JA Solar, or equivalent)
- Inverter (string or hybrid depending on package)
- Roof mounting system and all fixings
- Scaffolding and full electrical installation
- DNO notification and MCS registration

- Bird proofing or pigeon guards (often an optional extra)
How much do EON Next solar panels cost?
EON Next publishes genuinely aggressive entry pricing: from £4,995 for 6 panels and £6,495 for 12 panels (checked July 2026), with £150 to £200 off in periodic promotions. A from-price is the cheapest possible configuration though, and final quotes rise with roof complexity, scaffolding, location and battery choice. All prices include VAT (0% VAT applies to residential solar PV installations until March 2027).
| System Size | EON Next (est.) | Independent Installers (est.) | Difference |
|---|---|---|---|
| ~2.5 kW (6 panels) | From £4,995 (published) | £5,700–£7,000 (3 kW) | EON from-price cheaper on paper |
| ~5 kW (12 panels) | From £6,495 (published) | £8,300–£10,200 | EON from-price cheaper on paper |
| 12 panels + battery | From £8,395 (from-prices combined) | £9,500–£13,000 (4–5 kW + 5 kWh) | Compare tailored quotes like for like |
Read the from-price small print
A published from-price is the cheapest possible job: the smallest array, the standard battery brand, and a straightforward install. Your tailored quote is priced by a regional subcontractor after a survey, and roof complexity, scaffolding access or a premium battery like the Powerwall 3 can move it well above the headline figure. The equipment itself is typically identical to what independent local installers fit (same tier-one panels, same inverter brands), so judge the final quote, not the advert. Always compare at least 3 quotes before making a decision.
EON Next finance options
EON Next offers 0% APR finance for up to 3 years on solar and battery packages (subject to status and availability, checked July 2026), letting you spread the cost interest-free in monthly instalments. Longer terms may carry interest, and interest-bearing finance can add £1,000 to £3,000 to the overall cost, so always check the total cost of credit. Compare EON's offer against other suppliers' 0% deals and green loans from 3% APR in our solar panel finance guide.
EON Next smart tariffs & solar export
EON Next pushes the tariff bundle hard in its quotes, and for existing EON electricity customers it's the genuine reason to consider them. You get the EON Next solar export tariff and, if your meter supports it, time-of-use pricing on import. The catch: the export rate isn't market-leading, so the bundle only pays off if you value single-supplier admin over a higher SEG rate.
EON Next Solar Export
EON Next offers a Smart Export Guarantee (SEG) tariff that pays you for surplus electricity exported to the grid. Rates vary but are typically around 13p/kWh in 2026. See our full E.ON Next SEG export rate review for every tier and how it compares. Specialist tariffs from Octopus Energy may offer higher rates (up to 15p/kWh with Agile Export).
Battery optimisation
If you have a battery, EON Next’s app can help schedule charging and discharging to maximise savings. However, EON Next’s smart tariff options are currently less advanced than Octopus Energy’s Agile, Flux, or Intelligent Go tariffs, which offer more granular time-of-use pricing and better battery arbitrage opportunities.
How EON Next export rates compare
| Supplier | Export Rate | Notes |
|---|---|---|
| EON Next | ~13p/kWh | Fixed SEG rate |
| Octopus Energy (Fixed) | Up to 15p/kWh | Fixed SEG rate |
| Octopus Agile Export | Variable (avg 8–15p/kWh) | Half-hourly variable rate; best with battery |
| Octopus Flux | Up to 24p/kWh (peak) | Requires compatible battery; time-of-export pricing |
| British Gas | ~12–15p/kWh | Fixed SEG rate |

SolarInfo.uk editorial rating (out of 5)
Solid Tier 1 hardware and genuinely useful finance, marked down for pricing that runs above the independent MCS market and install quality that varies by subcontractor.
Our verdict in short: EON Next reviews land in the middle of the market. The hardware is solid Tier 1 kit, the finance is genuinely useful, but the price runs above the independent MCS market and install quality depends on which regional firm EON subcontracts your postcode to. Here is where it works and where it doesn't.
What you actually get
The real value in EON Next isn't the install. The kit that ends up on your roof is the same Tier 1 hardware (typically Longi or JA Solar with a Solis or Huawei inverter) that you would get from any decent MCS-certified local firm. What EON offers on top of that is brand reassurance, a single point of contact for survey, install and aftercare, and interest-free credit on selected packages. If you don't have the cash to pay outright and want a 10-year credit agreement with someone who will still be around in 2036, the finance side alone can make EON the right call.
The smart-tariff side also lines up cleanly if you're already an EON Next electricity customer. The export tariff isn't spectacular, but you get a single supplier handling import, export, and the MCS paperwork end-to-end. For a buyer who values one phone number to call, that matters.
Where the gap shows
Price is the obvious one. EON Next consistently quotes 10 to 20% above the independent MCS market for equivalent systems, and that gap doesn't buy you better panels, a longer warranty, or a faster install. It buys the call centre, the marketing, and the management overhead that comes with running a Big Six retail operation.
The install itself is subcontracted, which means quality depends entirely on which regional installer EON hands your postcode to. We see good outcomes in some counties and long Trustpilot complaint threads in others. The export tariff is also middle-of-the-road: if you have a battery and you're willing to switch supplier, Octopus Flux or Agile Export will out-earn EON's SEG by a meaningful margin over the system's lifetime. And lead times of 6 to 10 weeks from quote to install are typical, which is slower than most local installers managing their own calendars.
Short version: EON Next makes sense if you want a single national brand handling everything and you need finance. If you're cash-buying and willing to manage one local installer relationship, you'll save £500 to £1,500 on the same kit.
EON Next vs independent solar installers
The most important comparison for anyone considering EON Next solar panels is against independent, local MCS-certified installers. Here is how they stack up in 2026.
| Factor | EON Next | Independent Installers |
|---|---|---|
| Pricing | 10–20% higher on average | More competitive; lower overheads |
| Equipment | Tier-one brands (limited choice) | Wider choice of brands and models |
| Installation quality | Subcontracted; varies by region | Direct; often same team every time |
| Aftercare | Call centre support; can be slow | Direct contact with installer; often faster |
| Finance | 0% credit available on some packages | Some offer finance; varies by company |
| Smart tariffs | Integrated with EON Next export tariff | You choose any SEG provider (Octopus, etc.) |
| Flexibility | Standardised packages | System designed around your roof |
| Company stability | Large multinational; very low risk | Varies; check reviews and trading history |
Our recommendation
EON Next is a reasonable choice if you value convenience and the reassurance of a large brand. However, we recommend getting at least two or three quotes from independent MCS-certified installers before committing. You may find the same equipment installed for £500 to £1,500 less. The equipment, MCS certification, and manufacturer warranties are identical regardless of who installs the system.
What to check before buying from EON Next
Before you sign anything with EON Next, get the answers below in writing. Most buyer regret on Trustpilot traces back to one of these being assumed rather than confirmed.
Questions to ask EON Next
- Which panel brand and model will be installed?
- Which inverter brand and model (Huawei, SolarEdge, etc.)?
- What is the total cost including VAT, scaffolding, and all works?
- What is the workmanship warranty period and what does it cover?
- Who is the subcontractor carrying out the installation?
- What happens if there is a fault, and who do you contact?
- Is the finance APR 0% or will interest apply?
- Can you choose to add a battery later without losing warranty?
Red flags to watch for
- Pressure to sign on the day. Always take time to compare
- Vague equipment specs (“tier-one panels” without naming the brand)
- Finance terms that are unclear or have hidden fees
- Unrealistic savings projections (“eliminate your electricity bill”)
- No clear information on who handles warranty claims
- Inability to provide references or Trustpilot/Google reviews
EON Next also installs air source heat pumps, so you may be offered a combined package. If you're considering both, budget them together: our heat pump cost guide covers typical prices with the £7,500 grant applied.
EON Next Solar Panels FAQ
Are EON Next solar panels any good?
EON Next uses tier-one solar panels from reputable manufacturers like Longi and JA Solar, which are the same brands used by independent installers. The panels themselves are good quality. The main consideration is pricing: EON Next is typically 10 to 20% more expensive than independent MCS installers for equivalent systems. Installation quality depends on the subcontractor in your area.
How much do EON Next solar panels cost?
EON Next solar panels start from £4,995 for a 6-panel system and £6,495 for 12 panels on E.ON's published 2026 price list. A battery added at install starts from £1,900, or from £3,995 as a retrofit. Those are from-prices for the simplest configuration; tailored quotes rise with roof complexity, array size and battery choice. Always compare with at least two or three independent quotes.
Do I need to be an EON Next customer to buy their solar panels?
No. You do not need to be an existing EON Next energy customer to purchase their solar panel packages. However, some smart tariff benefits and export tariff integration work best if you are also an EON Next electricity customer.
What warranty do EON Next solar panels come with?
EON Next solar installations typically come with a workmanship warranty of 5 to 10 years covering the installation itself. The solar panels carry the manufacturer's product and performance warranty (usually 25 years). Inverters are typically warranted for 10 to 12 years by the manufacturer. Battery warranties vary by brand (usually 10 years).
Can I get a battery with EON Next solar panels?
Yes. EON Next offers solar panel + battery packages, as well as battery-only retrofits for homes that already have solar panels. Battery options typically range from 5 to 10 kWh. Popular battery brands used include Huawei Luna, GivEnergy, and Fox ESS, depending on availability.
How does EON Next compare to Octopus Energy solar?
Both EON Next and Octopus Energy offer solar panel packages. Octopus Energy's main advantage is its superior smart tariffs (Agile, Flux, Intelligent Go) which can save significantly more when paired with a battery. EON Next offers a more traditional, package-based approach. For either, compare their quote against independent MCS installers.
Is it better to buy solar panels from EON Next or an independent installer?
Independent MCS-certified installers typically offer the same equipment for 10 to 20% less than EON Next. They also tend to design more closely around your roof and handle aftercare directly. EON Next's advantages are brand trust, potential finance options, and convenience. We recommend getting quotes from both and comparing the total cost for equivalent equipment.
How long does EON Next solar installation take?
The process from initial enquiry to completed installation typically takes 6 to 10 weeks with EON Next. The installation itself usually takes 1 to 2 days for a standard system. Lead times can be longer during peak demand periods (spring and summer).
Do EON Next solar panels qualify for the Smart Export Guarantee?
Yes. All EON Next solar installations are MCS-certified, which is a requirement for the Smart Export Guarantee (SEG). You can choose any licensed electricity supplier for your SEG payments; you are not obliged to export to EON Next.
Can I switch energy supplier after installing EON Next solar panels?
Yes. Your solar panels and any warranties remain unaffected if you switch energy supplier. The panels and inverter carry manufacturer warranties that are independent of your energy supplier. You may lose specific EON Next tariff benefits, but you can sign up to SEG export with any licensed supplier.
