Short answer: my UK shortlist
If I were buying solar in the UK, I’d get three MCS-certified quotes and ask each installer to price the same spec: panels, inverter, battery, bird protection, scaffolding, DNO application, workmanship warranty and MCS handover. In the UK you usually buy solar through an installer, not directly from a panel maker, and Which? notes that many installers only offer one or two panel brands—so comparing quotes is more important than chasing a single “best” panel brand. (which.co.uk)
Best UK solar installers to shortlist
| Best for | Companies I’d shortlist | Why |
|---|---|---|
| Best overall route | A strong local MCS installer | Often better site survey, roof-specific design and aftercare. Check MCS, RECC/HIES/GGF consumer-code membership, insurance-backed workmanship guarantee and recent local reviews. Energy Saving Trust recommends MCS-accredited installers and at least three quotes. (energysavingtrust.org.uk) |
| Customer-service-led national option | Solar4Good | FMB’s September 2026 installer shortlist names Solar4Good “best customer service”; it also lists it as MCS-certified with a high customer-review rating. (fmb.org.uk) |
| Wider panel choice / national quote | Glow Green | Worth a quote if you want access to high-efficiency panel options; FMB lists Glow Green as best for range of high-efficiency panels. (fmb.org.uk) |
| Energy-supplier bundle | Octopus Energy Solar | Convenient if you already use, or plan to use, Octopus tariffs for export, EV charging or battery automation. I’d still compare against local MCS installers because the best tariff does not automatically mean the best install. Octopus offers solar-only and solar-with-battery installs. (octopus.energy) |
| Subscription / lower upfront cost | Sunsave | Sunsave markets a solar-and-battery subscription rather than a normal upfront purchase; useful if cash flow matters, but compare total lifetime cost carefully. (sunsave.energy) |
| Long-warranty pitch | Project Solar UK | Often shortlisted for long warranties, but compare the installed price and warranty terms very carefully—long panel warranties are only as useful as the installer/manufacturer support behind them. FMB lists Project Solar as MCS-certified and “best for long warranties.” (fmb.org.uk) |
Avoid relying on old “best installer” lists without checking trading status. For example, FMB notes that Effective Home, which appeared in older roundups, ceased trading at the end of June 2026. (fmb.org.uk)
Solar panel brands people actually use in the UK
These are the panel brands I’d be happy to see on a UK quote, assuming the specific model has a decent warranty and the installer is reputable:
| Brand | Best for | My view |
|---|---|---|
| JA Solar | Mainstream value | One of the safest “good value, widely fitted” choices. Often a strong default if the quote is competitive. |
| Trina Solar | Budget/value | Very common in UK quotes; good if you want sensible performance without paying premium-panel prices. |
| LONGi | Mainstream all-rounder | Another dependable volume brand; compare model-by-model against JA/Trina. |
| AIKO | High efficiency / limited roof space | Good when roof space is tight and you want more watts per panel. Which? lists AIKO among popular UK brands it tested, with high maximum efficiency figures in its July 2026 comparison. (which.co.uk) |
| Jinko Solar | Mainstream with stronger warranty options | Worth considering if your quote includes Tiger Neo or similar newer models; Which?’s 2026 comparison lists Jinko with a 30-year product warranty on the model compared. (which.co.uk) |
| REC | Premium panels | Usually pricier, but a good choice if you want premium build quality and stronger retained-output warranty figures. Which?’s comparison lists REC with 92% output at 25 years on the model compared. (which.co.uk) |
| Canadian Solar | Lower-cost mainstream | Fine if the installed price is attractive; just check the exact model warranty and output guarantee. |
Which? says its UK owner research and lab tests cover popular brands including AIKO, JA Solar, LONGi and Trina, and its 2026 comparison also includes Canadian Solar, Jinko, REC, SolarEdge and Trina. (which.co.uk) UK installer research also says major Chinese manufacturers dominate the UK module market, while brand choice is strongly influenced by wholesalers. (renewableenergyinstaller.co.uk)
Inverters and batteries I’d actually consider
| Setup | Best for | Notes |
|---|---|---|
| GivEnergy All-in-One / GivEnergy hybrid | Best UK-default battery ecosystem | Very common in UK quotes, good app/tariff ecosystem, and a strong option for people on time-of-use tariffs. GivEnergy’s All-in-One is a 13.5kWh AC-coupled battery system with a 6kW inverter and 12-year warranty. (givenergy.com) |
| Tesla Powerwall 3 | Premium battery, big capacity, backup-friendly | Good if you want a polished app, strong brand support and a single large battery. Tesla lists Powerwall 3 at 13.5kWh usable capacity, with expansion options, sold through certified installers. (tesla.com) |
| SolarEdge inverter + optimisers + Home Battery | Shading, multiple roof faces, panel-level monitoring | Good for complex roofs, dormers, chimneys or partial shading. SolarEdge’s Home Battery 400V is designed for SolarEdge residential systems; its warranty document lists a 10-year warranty period. (solaredge.com) |
| Enphase microinverters + IQ Battery | Shaded/multi-orientation roofs; modular design | Excellent technical solution where each panel needs to operate independently, but often costs more. Enphase’s UK warranty lists 25 years for covered IQ8 microinverters. (enphase.com) |
| Solis / SolaX / Fox ESS | Lower-cost hybrid inverter + battery quotes | Common in value quotes. I’d accept these from a good installer, but I’d scrutinise warranty, cloud/app reliability, battery throughput limits and local support. UK installer research names Solis and SolaX among brands with strong UK installer awareness/portfolio presence. (renewableenergyinstaller.co.uk) |
| Sigenergy SigenStor | Newer modular premium system | Interesting if you want a modular battery stack and future EV/energy-management features. It’s increasingly quoted, but because it’s newer in the UK, I’d be stricter about installer experience and warranty terms. Sigenergy lists 10 years for main unit/battery pack warranty on its EU warranty page. (sigenergy.com) |
For UK homes, installer research highlights Solis, GivEnergy, Tesla, Enphase and SolaX Power as brands that sit in the top group for UK installer awareness and portfolio presence in inverters/storage. (renewableenergyinstaller.co.uk)
My “safe” spec for a typical UK house
For a normal semi/detached house, I’d usually ask for quotes around:
- 4–6kWp of panels using JA Solar, Trina, LONGi, AIKO or Jinko
- 5–10kW inverter, depending on array size, export limit and battery
- 9–13.5kWh battery if you have evening usage, EV, heat pump, or a smart tariff
- Bird protection, especially if pigeons are common locally
- Scaffold, DNO G98/G99 paperwork, MCS certificate, electrical certificate and handover pack included
- At least 10 years workmanship cover, ideally insurance-backed
If you want the least risky brand combination, I’d start with JA Solar / Trina / LONGi panels + GivEnergy battery, or AIKO/Jinko panels + Tesla Powerwall 3 if you want a more premium setup.
Non-negotiables before signing
- Use an MCS-certified installer and MCS-certified products. You’ll commonly need an MCS certificate for Smart Export Guarantee payments, and Energy Saving Trust says installers should register your system within 10 working days of commissioning. (energysavingtrust.org.uk)
- Get three quotes. Energy Saving Trust specifically warns against heavy-handed sales tactics, “sign today” discounts and comparing on price alone. (energysavingtrust.org.uk)
- Don’t pay a huge deposit. Energy Saving Trust says your deposit should not be more than 25% of the full cost and should be protected with insurance. (energysavingtrust.org.uk)
- Ask for the exact model numbers. “JA Solar panels” or “GivEnergy battery” is not enough—ask for datasheets, warranty documents and the proposed roof layout.
- Compare payback using your real usage. Solar is best if you use power in the day, have a battery, charge an EV, run a heat pump, or can use a good export tariff.
My final recommendation: shortlist one good local MCS installer, Solar4Good or Glow Green, and Octopus Energy if tariff integration matters. For hardware, prioritise AIKO, JA Solar, Trina, LONGi, Jinko or REC panels, paired with GivEnergy, Tesla Powerwall 3, SolarEdge, Enphase, Solis/SolaX/Fox ESS or Sigenergy depending on your budget and roof complexity.

Best Solar Companies & Products in the UK (2026)
The UK solar market splits into two categories worth knowing: panel manufacturers (who make the tech) and installers (who sell and fit it). Here's what's actually recommended right now.
🏆 Top Solar Panel Brands
LONGi – Currently the top overall pick for most UK homes. The best solar panel for most UK homes in the 2026 comparison is the LONGi Hi-MO X10 485W, combining 23.8% efficiency, strong output and excellent long-term performance. It also has less than 1% first-year degradation, followed by annual degradation of approximately 0.35% from years two to 30.
Other standout panels by category:
- Best value: JA Solar JAM54D40 455W
- Highest efficiency: AIKO Neostar 3S
- Best long-term output retention: REC Alpha Pure-R
Premium option: SunPower panels offer industry-leading performance with efficiencies reaching up to 24%, and their low degradation rate ensures minimal loss of output over time. Expect to pay more — premium brands like SunPower Maxeon and REC reach 22.8–24% efficiency with warranties up to 40 years, worth the 15–25% premium mainly where roof space is tight.
Best mainstream "everyday" brands: JA Solar, LONGi, Trina Solar, Aiko and Qcells offer the best value, pairing 21–23% efficiency with 25–30 year warranties. These are the brands installers use most often on standard UK homes.
If you want a discreet, integrated look: Viridian is a UK-based manufacturer known for its roof-integrated solar panels — instead of sitting on top of the roof, these panels replace roof tiles, creating a seamless finish and reducing wind resistance.
🔧 Top Installers People Actually Use
Glow Green – Frequently ranked #1 overall. Crowned best overall for their combination of affordability, reliability and comprehensive service, using high-efficiency panels from brands like Perlight and DMEGC, flexible financing, and MCS/NICEIC accreditations.
Solar4Good – Excellent for panel/battery choice and reviews. They work with established panel brands such as Jinko, Trina, JA Solar, DMEGC and Aiko, and battery/inverter brands including GivEnergy, Fox ESS, Sigenergy and Tesla, and are rated 4.8/5 on Trustpilot with 775+ reviews and 9.7/10 on Checkatrade, having won the FMB Award 2024 for Best Customer Service. Trustpilot reviews specifically praise the high quality of after-sales care and customer service, as well as pricing and speed of installation.
Other well-regarded national installers: Effective Home and Project Solar have retained top spots for consistent quality, and Project Solar UK, Otovo, Geo Green Power, Sunsave, and Solar Fast are also frequently recommended.
For battery/subscription-style deals: Sunsave stands out as the only top-rated company offering solar subscriptions, which suits people who prefer no upfront cost.
