Glow Green has been crowned best overall choice due to their impressive combination of affordability, reliability and comprehensive service offerings, standing out with a range of high-efficiency solar panels from top brands like Perlight and DMEGC. They carry a strong 4.7 Trustpilot score across over 13,000 reviews.\n\n**Project Solar UK** is another long-standing heavyweight. Project Solar UK is one of the most experienced solar companies in the UK, with a track record of more than 45,000 installations completed. They're also often noted as having the best warranties in the industry.\n\nOther well-regarded names people actually use include:\n- **Solar4Good** – praised for its wide range of panel options and value for money\n- **Effective Home** – known for strong customer service\n- **Sunsave** – a London-based installer offering a \"solar subscription\" model (no upfront cost), certified by the MCS and Flexi-Orb, accredited by RECC, approved by TrustMark, registered with NAPIT, and is a Which? Trusted Trader\n- **So Energy** – good for fast turnarounds, with a huge Trustpilot presence\n- **Octopus Energy** – the UK's biggest energy supplier, now also offering solar, backed by an enormous customer base (4.8 stars across 739,000+ reviews)\n- **Geo Green Power** and **Joju Solar** – solid regional/specialist options, the latter known for school and public-sector installs\n\nA smart approach echoed by most experts: a smaller, local installer might be just as reliable and provide a more personalised service; however, make sure to check customer reviews on sites like Trustpilot before you commit.\n\n## Best Solar Panel Brands (what's actually on UK roofs)\n\nInstallers don't manufacture panels — they source from a handful of trusted global brands. The current consensus for 2026:\n\n**Premium tier (best efficiency, longest warranties):**\n- SunPower Maxeon — the longevity champion, with a 40-year product and performance warranty and the lowest degradation of any panel sold in the UK, best where you want maximum output from a small roof.\n- AIKO Neostar — the efficiency leader, with back-contact (ABC) cells reaching around 24% efficiency and coping with partial shade better than most.\n- REC Alpha Pure-RX — premium European-engineered build with excellent low-light performance, which suits our often-overcast climate.\n\n**Mainstream Tier 1 (best value for most homes):**\n- For most UK homes in 2026, mainstream Tier 1 panels — JA Solar, LONGi, Trina Solar, Aiko and Qcells — offer the best value, pairing 21–23% efficiency with 25–30 year warranties.\n- Trina Solar is also a standout for coastal/exposed properties thanks to its durability against salt-mist corrosion.\n\n**For Scotland and northern UK (lower light conditions):** REC Alpha Pure or Jinko Tiger Neo are commonly recommended for their performance in diffuse, overcast light.\n\n## Other Equipment Brands Worth Knowing\nBeyond the panels themselves, reputable installers typically pair them with trusted inverter and battery brands — commonly **SolarEdge, SMA, Enphase, and GivEnergy** for inverters, and **Tesla Powerwall, GivEnergy, or LG Chem** for battery storage.\n\n## Bottom Line Recommendation\nIf you want a hassle-free, well-reviewed nationwide installer: **Glow Green** or **Project Solar UK** are the safest bets most people go with.

For most homes, the best value is a well-reviewed **local MCS-certified installer**, not a national brand. If you want big UK names, **Octopus Energy Solar**, **E.ON Solar**, **British Gas Solar**, **Effective Home** and **Project Solar UK** are commonly used — plus council-run **Solar Together** schemes.

Premium installs often use REC/Q Cells panels with SolarEdge/Enphase and a Tesla Powerwall or GivEnergy battery.\n\n### How to choose safely\n- Use an **MCS-certified installer** — needed for Smart Export Guarantee payments and many warranties.\n- Check **TrustMark, RECC or Which? Trusted Traders**.\n- Ask for an insurance-backed workmanship warranty (10+ years).\n- Confirm DNO approval, MCS certificate and export tariff options.\n- Get at least 3 quotes; avoid cold-call pressure sales.\n- 0% VAT currently applies to qualifying residential solar/battery installations.\n\nIf you tell me your rough location, roof direction and annual electricity use, I can narrow down likely panel/battery sizes and brands for your situation.","extractedBrands":[{"name":"Octopus Energy Solar","domain":"octopusenergy.com","position":3},{"name":"E.ON Solar","domain":"eon.co.uk","position":4},{"name":"British Gas Solar","domain":"britishgas.co.uk","position":5},{"name":"Effective Home","domain":null,"position":6},{"name":"Project Solar UK","domain":"projectsolaruk.com","position":7},{"name":"Solar Together","domain":null,"position":8},{"name":"Jinko","domain":null,"position":9},{"name":"Longi","domain":null,"position":10},{"name":"JA Solar","domain":null,"position":11},{"name":"Trina","domain":null,"position":12},{"name":"Canadian Solar","domain":"canadiansolar.com","position":13},{"name":"REC","domain":null,"position":14},{"name":"Q Cells","domain":null,"position":15},{"name":"SunPower","domain":"maxeon.com","position":16},{"name":"GivEnergy","domain":null,"position":17},{"name":"Sunsynk","domain":null,"position":18},{"name":"Solis","domain":null,"position":19},{"name":"Growatt","domain":null,"position":20},{"name":"Huawei","domain":"huawei.com","position":21},{"name":"SolarEdge","domain":null,"position":22},{"name":"Enphase","domain":"enphase.com","position":23},{"name":"SMA","domain":null,"position":24},{"name":"Fronius","domain":null,"position":25},{"name":"Tesla","domain":"tesla.com","position":26},{"name":"Fox ESS","domain":null,"position":27},{"name":"Pylontech","domain":null,"position":28},{"name":"Myenergi","domain":"myenergi.com","position":29}]},{"provider":"gemini","run":1,"model":"gemini-3.5-flash","capturedAt":"2026-10-14T11:46:36.754Z","text":"If you are looking to install solar panels in the UK, the market has matured significantly. Because of the British climate and our unique dynamic energy tariffs, the \"gold standard\" setup for most UK homes is now a hybrid system: **solar panels paired with a smart home battery**. \n\nCombining panels and batteries is highly advantageous, especially with the **0% VAT incentive on home solar and battery storage** (running until March 2027).\n\nThis guide breaks down the best solar installers (the companies), the best panels, and the battery brands that UK homeowners actually use.\n\n---\n\n### Part 1: The Best Solar Installers in the UK (The Companies)\n\nIn the UK, you don’t typically buy the hardware yourself; you choose an installer who packages the panels, inverter, and battery together. It is **absolutely essential** that your installer is **MCS (Microgeneration Certification Scheme) certified**. Without an MCS certificate, you cannot register for the Smart Export Guarantee (SEG) to sell your excess electricity back to the grid.\n\nHere are the top national companies leading the UK market:\n\n#### 1. Octopus Energy (Solar & Storage)\n* **Best for:** Existing Octopus customers and smart-home integration.\n* **Why people use them:** Octopus has revolutionized home energy in the UK. If you install through them, they seamlessly hook you up to their market-leading smart tariffs (like *Octopus Flux* or *Agile Octopus*), allowing you to import dirt-cheap electricity at night to fill your battery and export it back to the grid when rates peak. \n* **Trustpilot Rating:** Very high (brand-wide).\n\n#### 2. Sunsave\n* **Best for:** No upfront cost (subscription model).\n* **Why people use them:** Sunsave is a Which? Trusted Trader with a stellar reputation. They offer \"Sunsave Plus,\" a monthly solar subscription starting from around £69/month with £0 upfront cost. Unlike old \"rent-a-roof\" schemes, you own the panels from day one, meaning you get to keep all the savings and SEG export income.\n* **Trustpilot Rating:** 4.8/5.\n\n#### 3. Heatable\n* **Best for:** Transparent, instant fixed pricing.\n* **Why people use them:** Heatable changed the game by offering instant, transparent quotes online without making you sit through a high-pressure, two-hour sales pitch in your living room. They use top-tier hardware (like AIKO panels and GivEnergy batteries) and can get systems installed incredibly quickly.\n* **Trustpilot Rating:** 4.8/5.\n\n#### 4. Project Solar UK\n* **Best for:** Longevity and massive volume.\n* **Why people use them:** As one of the largest and longest-established national installers, they have completed over 45,000 installations. They offer some of the longest product warranties in the industry (often up to 30 years) and are a very stable \"big brand\" choice.\n* **Trustpilot Rating:** 4.6/5.\n\n> 💡 **A Note on Local Installers:** Don't ignore local, independent MCS-certified installers. National companies are great, but local firms often offer highly competitive rates and excellent, personalized customer service. Check the **MCS Directory** and local Trustpilot reviews to find accredited teams in your area.\n\n---\n\n### Part 2: The Best Solar Panels (The Hardware)\n\nWhen looking at quotes, you’ll want to pay attention to the panel brand being offered. The trend has shifted heavily toward **All Back Contact (ABC)** and high-efficiency monocrystalline panels that look sleek (all-black) and perform well in the overcast British weather.\n\n#### 1. AIKO (e.g., Neostar series)\n* **The Verdict:** The current UK market darling.\n* **Why they are great:** AIKO panels lead the industry in efficiency (exceeding 23–24%). They are entirely black (no silver gridlines on the front), which looks fantastic on slate or tiled roofs. Crucially, they have brilliant \"partial shading\" optimization, meaning if a chimney cast a shadow on one corner of the panel, the rest of the panel doesn't completely lose power.\n\n#### 2. SunPower Maxeon (e.g., Maxeon 7)\n* **The Verdict:** The absolute premium \"rolls-royce\" option.\n* **Why they are great:** Maxeon panels are incredibly durable and come with a jaw-dropping 40-year product and performance warranty. They offer elite efficiency and perform exceptionally well in low-light conditions. The only downside is the premium price tag.\n\n#### 3. LONGi (e.g., Hi-MO series) & JinkoSolar\n* **The Verdict:** The best-value \"workhorse\" panels.\n* **Why they are great:** These are Tier 1, mass-production giants. LONGi’s Hi-MO series is incredibly reliable, highly efficient, and much more budget-friendly than Maxeon or AIKO. If you have a large roof and want a faster return on your investment, these are the panels to get.\n\n#### 4. DMEGC\n* **The Verdict:** The budget-friendly favorite.\n* **Why they are great:** Widely used by UK installers as a standard budget-friendly option. They are highly reliable, offer great performance-to-cost ratios, and feature sleek, all-black aesthetics.\n\n---\n\n### Part 3: The Best Home Battery Storage (The Brains)\n\nBecause UK electricity prices are high during peak hours (4 PM – 7 PM), a battery is vital to store your solar generation so you don't have to buy expensive grid energy.\n\n#### 1. Tesla Powerwall 3\n* **The Verdict:** The most technologically advanced, fully integrated system.\n* **Why people use it:** The Powerwall 3 includes a built-in hybrid inverter, meaning you don't need a separate box on the wall. It has a massive 13.5 kWh capacity and can discharge a huge amount of power simultaneously (meaning you can run your kettle, oven, and heat pump all at once without pulling from the grid). Its settings can be dynamically configured, which makes getting approval from your local energy network operator (DNO) much easier.\n\n#### 2. GivEnergy (e.g., Giv-Bat)\n* **The Verdict:** The UK's domestic favorite.\n* **Why people use it:** GivEnergy is a British brand with excellent UK-based customer support. Their batteries are modular (ranging from 5.2 kWh to 9.5 kWh+), meaning you can start with one battery and easily stack more on later if your energy needs grow.

A good installer handles all of this paperwork for you.\n4. **Choose a Smart Tariff:** Once your system is live, immediately switch to a smart export tariff (like *Octopus Flux* or *Agile*) to maximize your savings.","extractedBrands":[{"name":"Octopus Energy","domain":"octopus.energy","position":1},{"name":"Sunsave","domain":null,"position":2},{"name":"Heatable","domain":null,"position":3},{"name":"Project Solar UK","domain":null,"position":4},{"name":"AIKO","domain":null,"position":5},{"name":"SunPower","domain":"sunpower.com","position":6},{"name":"LONGi","domain":null,"position":7},{"name":"JinkoSolar","domain":null,"position":8},{"name":"DMEGC","domain":null,"position":9},{"name":"Tesla","domain":"tesla.com","position":10},{"name":"GivEnergy","domain":null,"position":11},{"name":"myenergi","domain":null,"position":12}]},{"provider":"google_ai_mode","run":1,"model":"google_ai_mode","capturedAt":"2026-10-14T11:46:36.754Z","text":"The best solar setups in the United Kingdom are built on a clear distinction between the Tier 1 manufacturers who make the equipment and the MCS-certified installers who actually bolt them to your roof.\n\nFor most UK homes, the top-rated brands are JA Solar, LONGi, and Trina Solar for overall value, SunPower Maxeon for premium efficiency, and companies like Project Solar UK or Glow Green for reliable nationwide installation.\n\nThe UK market is dominated by global Tier 1 manufacturers whose panels are highly optimized for diffuse light and typical British overcast conditions.\n\nBrand | Category | Key Specs | Best For\nSunPower (Maxeon) | Premium | 22–24% efficiencyUp to 40-year warranty | Maximum output where roof space is tight or limited.\nJA Solar | Mainstream Value | 21–23% efficiency25-year performance warranty | Best budget balance.

([energypages.co.uk](https://energypages.co.uk/solar/best-installers/)) |\n| **Solar4Good** | Customer service / premium install | High review scores and FMB’s “best customer service” pick; supplies mainstream brands such as JA Solar, Jinko, Trina, Qcells and Fox ESS. ([fmb.org.uk](https://www.fmb.org.uk/homepicks/solar-panels/solar-panel-installers/)) |\n| **Octopus Energy Solar** | One-app ecosystem: energy tariff + battery + EV | Best if you already use or want Octopus smart tariffs, EV charging and battery/export integration. Note: some published review scores are for the wider Octopus Energy group, not only solar. ([expertsure.com](https://www.expertsure.com/uk/solar-panels/best-solar-panel-installers/)) |\n| **Heatable Solar** | Fast online quoting / transparent process | Good if you want a quick fixed-price style quote without a traditional sales visit; check local installer quality because coverage is via partner installers. ([expertsure.com](https://www.expertsure.com/uk/solar-panels/best-solar-panel-installers/)) |\n| **Project Solar** | Established, high-volume installer | One of the longer-running UK residential solar installers with a large review base; worth quoting if price is important. ([fmb.org.uk](https://www.fmb.org.uk/homepicks/solar-panels/solar-panel-installers/)) |\n| **Glow Green** | Solar plus boiler / heat pump work | Good if you want solar bundled with wider home-energy upgrades; it has a very large review base, though not all reviews are solar-specific. ([energypages.co.uk](https://energypages.co.uk/solar/best-installers/)) |\n| **Sunsave** | Consumer protection / subscription option | Strong on accreditations and offers a subscription model; Sunsave’s own ranking also notes it is MCS/Flexi-Orb certified, RECC accredited, TrustMark approved and a Which? Trusted Trader.

Local firms can be better value and more flexible than national installers, but you must check certification, reviews and warranty terms.\n\n---\n\n## The panel brands people actually get in UK quotes\n\nIn the UK you usually don’t buy panels like you’d buy a TV; your installer typically proposes the panels they stock. Which? says UK homeowners generally buy through an installer, many installers work with only one or two panel brands, and it recommends getting three quotes so you can compare what you’re being offered. ([which.co.uk](https://www.which.co.uk/reviews/solar-panels/article/best-solar-panel-brands/solar-panel-brand-reviews-a1rAN1R8nYFD))\n\n### Best mainstream panel brands to accept in a quote\n\n| Brand / product family | Good for | Verdict |\n|---|---|---|\n| **JA Solar DeepBlue** | Best value all-rounder | Very common in UK quotes; good efficiency, bankable manufacturer, sensible price. |\n| **Jinko Solar Tiger Neo** | Mainstream value | Another very common Tier-1 choice; fine if the price is good. |\n| **LONGi Hi-MO** | High efficiency at a reasonable price | A strong “safe pick” if quoted competitively. |\n| **Trina Vertex S+** | Compact, good-value panels | Often good for residential roofs where dimensions matter. |\n| **Aiko Neostar** | Highest output on tight roofs | Worth paying extra if roof space is limited or you need maximum watts per panel. |\n| **DMEGC Infinity / similar** | Budget-value installs | Increasingly seen in UK quotes; good if the installer is reputable and the warranty is clear. |\n| **REC Alpha / SunPower Maxeon** | Premium, long-warranty installs | Usually only worth the premium if roof space is tight or you really value the longer warranty. |\n| **Qcells / Canadian Solar** | Solid alternatives | Acceptable Tier-1 options if price and warranty are competitive. |\n\nWhich?’s 2026 brand comparison includes popular UK brands such as **Aiko, JA Solar, Jinko Solar, Longi, REC, SolarEdge and Trina**, and shows material differences in warranties, efficiency and output. ([which.co.uk](https://www.which.co.uk/reviews/solar-panels/article/best-solar-panel-brands/solar-panel-brand-reviews-a1rAN1R8nYFD))\n\n**My default panel recommendation for most UK homes:**  \n**JA Solar, Jinko, LONGi or Trina** if the price is good. Choose **Aiko** if you have a small roof and need maximum output per panel.\n\n---\n\n## Batteries and inverters people actually use\n\nIf you’re adding a battery, these are the names I’d be happy to see in a UK quote:\n\n| Product / brand | Best for | Notes |\n|---|---|---|\n| **GivEnergy All in One / Gen 3 systems** | UK-focused value | Popular in the UK, good app/tariff integration, often strong value per kWh. |\n| **Tesla Powerwall 3** | Simple premium battery | Polished app, strong inverter capacity, good if you want a set-and-forget premium system. |\n| **Sigenergy SigenStor** | Modular, future-proof system | Good if you want expandable storage, backup options and EV integration. |\n| **Fox ESS** | Budget/value battery systems | Common in UK installer quotes; check warranty and app reliability. |\n| **SolarEdge Home Battery + optimisers** | Shaded or complex roofs | Good where shade management matters. |\n| **Enphase microinverters / batteries** | Complex roofs, panel-level control | Premium option, especially for multi-aspect or shaded roofs. |\n\nFor most homes, I’d compare **GivEnergy vs Tesla Powerwall 3 vs Sigenergy** first. If the quote is budget-led, **Fox ESS** can make sense. If you have shading or many roof aspects, consider **SolarEdge optimisers** or **Enphase microinverters**.\n\n---\n\n## What to insist on before signing\n\n1. **MCS or Flexi-Orb certification** — especially if you want export payments. Energy Saving Trust advises using MCS-certified installers, and SEG eligibility usually requires MCS certification and a smart meter; Ofgem/Parliamentary guidance refers to MCS or an equivalent accredited scheme. ([energysavingtrust.org.uk](https://energysavingtrust.org.uk/advice/solar-panels/?loc=england))  \n2. **Three written quotes** with the exact panel make/model, inverter, battery, scaffolding, bird protection, DNO application, VAT and warranties listed. Energy Saving Trust specifically recommends getting at least three installer quotes. ([energysavingtrust.org.uk](https://energysavingtrust.org.uk/advice/solar-panels/?loc=england))  \n3. **A real roof survey**, not just a Google Maps estimate, especially if you have dormers, shading, old tiles or a slate roof.  \n4. **Workmanship warranty of at least 5 years**; 10 years is better.  \n5. **Clear export-tariff plan** — e.g. Octopus, E.ON, EDF, OVO etc. Export rate can matter more than tiny differences between panel brands.  \n6. **Avoid pressure selling** — no “today only” discounts, oversized deposits or vague payback assumptions.\n\n---\n\n## My top recommendation\n\nFor a typical UK homeowner, I’d aim for:\n\n- **Installer:** Contact Solar, Solar4Good, Octopus, Heatable, Project Solar, Glow Green, Sunsave **or a strong local MCS installer**\n- **Panels:** **JA Solar, Jinko, LONGi or Trina** for best value; **Aiko** if roof space is tight\n- **Battery:** **GivEnergy** for value, **Tesla Powerwall 3** for simplicity, **Sigenergy** for modular/future-proof setups\n- **Must-have:** MCS/Flexi-Orb certificate, DNO paperwork, written warranties, and at least three comparable quotes.","extractedBrands":[{"name":"Contact Solar","domain":null,"position":1},{"name":"Solar4Good","domain":null,"position":2},{"name":"Octopus Energy Solar","domain":null,"position":3},{"name":"Heatable Solar","domain":null,"position":4},{"name":"Project Solar","domain":null,"position":5},{"name":"Glow Green","domain":null,"position":6},{"name":"Sunsave","domain":"sunsave.energy","position":7},{"name":"JA Solar","domain":null,"position":8},{"name":"Jinko Solar","domain":null,"position":9},{"name":"LONGi","domain":null,"position":10},{"name":"Trina","domain":null,"position":11},{"name":"Aiko","domain":null,"position":12},{"name":"DMEGC","domain":null,"position":13},{"name":"REC","domain":null,"position":14},{"name":"SolarEdge","domain":null,"position":15},{"name":"GivEnergy","domain":null,"position":16},{"name":"Tesla","domain":null,"position":17},{"name":"Sigenergy","domain":null,"position":18},{"name":"Fox ESS","domain":null,"position":19},{"name":"Enphase","domain":null,"position":20}]},{"provider":"perplexity","run":1,"model":"sonar","capturedAt":"2026-10-14T11:46:36.754Z","text":"The strongest UK solar choices are **Heatable, Octopus Energy, Project Solar UK, Solar4Good, Glow Green, and Solar Fast**. For equipment, commonly recommended brands include **AIKO, REC, SunPower/Maxeon, JA Solar, JinkoSolar, SolarEdge, GivEnergy, and Tesla**—but installer quality matters as much as the panel brand.\n\n## Best UK solar installers\n\n| Company | Best for | Why consider it |\n|---|---|---|\n| **Heatable** | Transparent online buying and batteries | A well-known national installer with strong customer-review performance; recent comparisons list it at 4.8/5 from more than 2,500 Trustpilot reviews.[1][2] |\n| **Octopus Energy Solar** | Existing Octopus customers and smart tariffs | Useful if you want solar, battery storage and tariff integration under one energy supplier. |\n| **Project Solar UK** | Large national installer and long warranties | One of the biggest established UK solar installers; compare its warranty terms carefully because some cover is product-specific.[1][2] |\n| **Solar4Good** | High customer ratings | Recent UK installer comparisons report a 4.7/5 Trustpilot score, although it has a smaller review base than the largest firms.[1][3] |\n| **Glow Green** | Solar plus broader home-energy upgrades | Offers solar, batteries and related energy products; its published comparison lists Solar Fast at 4.7/5 from more than 2,000 reviews.[1][4] |\n| **Solar Fast** | Regional coverage and established operations | A frequently listed UK installer with substantial review volume and experience.[1][4] |\n| **Effective Home** | Larger home-improvement projects | Worth comparing when solar is being installed alongside insulation, heating or other efficiency work.[1] |\n\n**Best shortlist for most homeowners:** obtain quotes from **Heatable, Octopus Energy Solar, and one strong local MCS-certified installer**, then compare the specification rather than choosing solely by headline price.\n\n## Solar panels people actually use\n\n- **AIKO Neostar** — high-efficiency panels, particularly useful where roof space is limited; AIKO is consistently included among leading panels available in the UK.[5]\n- **REC Alpha** — premium, efficient panels with a strong reputation for build quality.\n- **Maxeon/SunPower** — premium panels with high efficiency and good performance in constrained roof areas; SunPower is listed among major manufacturers available in Britain.[3][5]\n- **JA Solar** — a common value-oriented choice with broad UK installer availability.\n- **JinkoSolar** — another widely installed, competitively priced mainstream brand.\n- **SolarEdge** — a popular inverter and optimiser system, especially where a roof has shading or several orientations.\n- **GivEnergy** — a widely considered UK battery-and-inverter option, often paired with solar panels.\n- **Tesla Powerwall** — a premium battery option for households prioritising storage capacity, backup capability and a polished app experience.\n\nPanel efficiency is not the only consideration: warranty length, degradation rate, inverter quality, shading design and the installer’s workmanship usually have a greater effect on real-world results than small differences between reputable panel brands.\n\n## What to demand in a UK quote\n\n- **MCS certification** for the installer, especially if you want access to the Smart Export Guarantee.\n- A detailed roof layout showing panel orientation, shading assumptions and expected annual generation.\n- The exact panel, inverter and battery model numbers—not merely “Tier 1 panels”.\n- Separate **product**, **performance** and **installation/workmanship** warranty terms.\n- A battery quote showing usable capacity, round-trip efficiency, maximum charge/discharge power and warranty throughput.\n- Confirmation that the installer will handle DNO notification and commissioning.\n- A realistic payback calculation using your actual electricity use, not optimistic export assumptions.\n- At least three comparable quotes, including one reputable local installer.\n\nFor a typical UK home, a sensible starting specification is **AIKO, REC, JA Solar or JinkoSolar panels with a GivEnergy or SolarEdge system**, while **Tesla Powerwall** is worth considering when battery features and backup power are priorities. The best purchase is usually the installer offering the clearest design, credible generation estimate and strongest after-sales support—not necessarily the cheapest panel.","extractedBrands":[{"name":"Heatable","domain":"heatable.co.uk","position":1},{"name":"Octopus Energy","domain":"octopus.energy","position":2},{"name":"Project Solar UK","domain":null,"position":3},{"name":"Solar4Good","domain":null,"position":4},{"name":"Glow Green","domain":"glowgreenltd.com","position":5},{"name":"Solar Fast","domain":null,"position":6},{"name":"AIKO","domain":null,"position":7},{"name":"REC","domain":null,"position":8},{"name":"SunPower","domain":"sunpower.com","position":9},{"name":"Maxeon","domain":"maxeon.com","position":10},{"name":"JA Solar","domain":null,"position":11},{"name":"JinkoSolar","domain":null,"position":12},{"name":"SolarEdge","domain":null,"position":13},{"name":"GivEnergy","domain":null,"position":14},{"name":"Tesla","domain":"tesla.com","position":15}]}]}
