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.

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.

🔋 Battery & Inverter Brands to Pair With Panels

The names that come up repeatedly alongside top panel brands are GivEnergy, Fox ESS, Sigenergy, and Tesla for batteries/inverters — these are commonly b

The best solar options in the UK depend on your roof size, budget, location, and priorities like efficiency, warranty length, or value for money. There’s no universal “best,” but based on 2026 expert comparisons, customer reviews (Trustpilot, Google, etc.), installer data, and market availability, here are the most popular and highly regarded panel brands and installation companies that real UK homeowners are using.

Focus on MCS-certified installers and Tier-1 panel manufacturers (per BloombergNEF lists) for reliability, warranty support, and performance in UK conditions (including lower light and diffuse skies). Most residential systems use monocrystalline N-type panels (e.g., TOPCon or similar tech) in the 400–500W+ range.

Top Panel Brands & Products People Actually Use

These are the brands dominating UK residential installs (nine brands account for over 90% of installations). Mid-tier options are the volume leaders for most homes; premiums suit smaller/shaded roofs or long-term owners.

• JA Solar (e.g., DeepBlue 4.0 or JAM series) and Jinko Solar (Tiger Neo series): Best overall value and most widely installed. Reliable performance, competitive pricing, strong UK distribution, and good warranties (typically 12–30 years product/performance). Popular default choice for many MCS installers.
• LONGi (Hi-MO X10 or similar): Excellent for high output per panel and efficiency (often 23%+). Strong mid-to-upper tier pick with good low-light performance.
• Trina Solar (Vertex S+ series): Solid mid-tier balance of price, efficiency, and warranties. Frequently recommended alongside JA Solar/Jinko.
• Aiko (Neostar series): Top for efficiency (often 24–25%+) and shade tolerance—ideal for smaller or partially shaded UK roofs. Premium but increasingly popular.
• SunPower Maxeon (e.g., Maxeon 7 or 6): Best for longevity (up to 40-year warranties) and lowest degradation. Premium choice for maximum lifetime output, especially if you plan to stay long-term.
• REC (Alpha Pure-RX or similar): Strong premium performer with excellent low-light results and warranties (25 years+). Good all-rounder in expert tests.

Other notables: DMEGC (good value/longevity options), Canadian Solar, and Perlight. Avoid unproven smaller brands for warranty peace of mind.

Installed costs (rough 2026 guide for a typical ~4kWp system): £6,000–£12,000+ depending on panels, battery add-ons, and installer—mid-tier often delivers the best £/kWh over 25 years.

Top Installation Companies People Use

These stand out in 2026 reviews for customer satisfaction, coverage, pricing transparency, and track record. Prioritise those with strong Trustpilot/Google scores (thousands of reviews where possible), insurance-backed warranties, and MCS accreditation.

• Glow Green: Frequently ranked best overall. Competitive fixed pricing (£795–£1,195 per kW installed), nationwide coverage (Great Britain), long track record (since 2011), and insurance-backed guarantees. Good for straightforward installs.
• Solar4Good: Highest customer satisfaction in many comparisons. Excellent reviews, nationwide, strong aftercare (10-year workmanship + 25-year panel warranties), and quick timelines. Family-run appeal.
• Octopus Energy (Solar Services): Popular for tariff integration (e.g., high export rates via Octopus Flux/Intelligent tariffs), fair pricing, and ecosystem benefits (battery/EV pairing). Good for those already with Octopus energy.
• Heatable: High review scores (around 4.8/5 with thousands of reviews), transparent online fixed pricing, nationwide (England & Wales focus in some reports), and solid warranties. Often praised for ease and quality.
• Project Solar: Large-scale installer with thousands of installs and strong ratings. Good for budget-conscious buyers and broad coverage.

Other strong options: OVO, Wickes Solar, Sunsave (subscription-style with long guarantees), Everyone’s Energy (urban/leasehold focus), and various high-rated local MCS firms (check recent Google/Trustpilot for your area).

Key Advice for UK Homeowners

• Get 3+ quotes from MCS-certified installers via comparison sites or direct (e.g., Heatable or Glow Green for speed). Check the MCS register.
• Factor in Smart Export Guarantee (SEG) payments, potential battery storage (GivEnergy, Tesla, etc., are common), and roof suitability.
• Look for insurance-backed workmanship warranties (5–10+ years) alongside manufacturer panel warranties.
• Reviews matter—prioritise companies with volume of recent feedback. Local specialists can excel in specific regions.
• Efficiency and low-light performance matter more in the UK than peak lab ratings. N-type panels generally outperform older tech.

Prices and availability shift, so verify current details directly. For the latest personalised advice, search MCS installers near you or use reputable comparison tools. If your roof has shading or limited space, lean toward higher-efficiency options like Aiko. Enjoy the savings—many UK households report strong returns!
