Who are Perlight Solar?
Perlight Solar was founded in 2006 and is a Chinese manufacturer backed by a group with manufacturing roots stretching back to the 1980s. It’s not a top-three global name like JA Solar or LONGi, but it’s far from a no-name importer either — and it does one thing most rivals at this price don’t: it runs its own sales and customer centre in Oxford (via its UK operation).
That UK presence matters more than it sounds. With many budget and mid-range brands, a warranty claim means chasing an installer who has to chase a distributor who has to chase a factory overseas. With Perlight, there’s a UK operation whose job is to handle exactly that. For a 25–30 year investment, being able to reach someone in this country is a real, practical advantage. See how the big brands compare in our best solar panels UK guide.

Perlight’s current line-up centres on modern N-type TOPCon cells — the higher-performing cell type that has replaced older PERC across the industry — in the same monocrystalline technology that makes up virtually the whole UK market (poly is obsolete; see mono vs poly). The headline models UK homeowners will see include:
| Model | Type | Notes |
|---|---|---|
| Delta Plus (all-black) | N-type TOPCon mono | ~430–485W, discreet all-black — the popular residential pick |
| 515W Double Glass | N-type TOPCon bifacial | Dual-glass, top-end efficiency, larger format |
| Delta (single glass) | Mono | Compact formats for smaller/awkward roofs |
The all-black Delta Plus is the one most UK homes end up with — the uniform black look homeowners want, in the practical 430–485W band. The compact formats are a genuine plus for awkward or smaller roofs where fitting a neat array matters. As always, don’t fixate on a single wattage: your installer picks the exact model to suit your roof dimensions and your DNO’s export limit.

Our rating
Perlight Delta Plus
★★★★ Great warranty & UK support for the money
The bottom line: a modern, well-priced panel whose 30-year warranty and UK support punch well above its brand recognition. Held back only by smaller global scale.
Get my Perlight price →Efficiency & output
Perlight’s N-type TOPCon range reaches around 22–23% efficiency, with the bifacial double-glass 515W model at the top end. That’s very competitive — comfortably ahead of older panels and right in the same bracket as JA Solar and Jinko. It sits below the premium back-contact panels from Aiko, which push past 24%, but for a normal roof that gap rarely matters (you simply fit the array you need).
Two useful points on real-world output. First, reviewers consistently note Perlight’s strong low-light performance — useful for the UK’s grey days. Second, the bifacial double-glass models can capture a little extra reflected light, though the real-world gain depends heavily on your roof and mounting, so treat the very highest quoted efficiency figures with healthy caution. For the fundamentals, see our solar panel efficiency guide.

Get My Perlight Price →The 30-year warranty
This is Perlight’s headline act. In the UK the panels are marketed with up to a 30-year product warranty and a 30-year performance warranty — among the longest coverage available on any panel, and noticeably longer than the 12–25 years many mainstream brands offer on the product itself.
| Cover | Perlight (UK) |
|---|---|
| Product warranty (faults/defects) | Up to 30 years |
| Performance warranty | 30 years |
| Cell type | N-type TOPCon (monocrystalline) |
| UK support | Yes — Oxford centre |
Two honest notes. First, the strongest terms are the ones offered in the UK through the UK operation — factory baseline datasheets can quote shorter terms, so always confirm the exact figures in writing on your quote. Second, and this is the golden rule for any brand: a panel warranty is only as good as the installer who fits them. Poor workmanship isn’t covered by the panel maker. That’s why we only match you with vetted, MCS-certified installers.
UK price
Perlight sits in the value-to-mid price bracket. As a fully-fitted system, a typical 4kW–5kW array lands around £5,000–£7,000 with 0% VAT, depending on your roof, scaffolding and whether you add a battery. Per panel they’re priced alongside mainstream brands like Jinko, JA Solar and DMEGC — cheaper than premium names like Aiko or LONGi, while giving you that stand-out warranty.
The smart way to judge any panel is cost per kWh generated over its lifetime — and a 30-year warranty stretches that lifetime confidence further than most. For the full breakdown, see our cost of solar panels guide and the grants available in 2026.
Perlight vs Aiko, JA Solar & Jinko
| Brand | Best for | Efficiency | Standout |
|---|---|---|---|
| Perlight | Long-term peace of mind + UK support | ~22–23% | 30yr warranty, Oxford centre |
| Aiko | Small/shaded roofs | Up to ~24.5% | Back-contact efficiency |
| JA Solar | Best value at scale | ~22.7% | Top-three global maker |
| Jinko | Proven value | ~22–23% | Huge global scale |
The honest summary: on raw specs Perlight is very close to JA Solar and Jinko. Where it pulls ahead is aftercare — the 30-year warranty and a UK support centre are a stronger safety net than most mid-range rivals offer. Where it falls behind is scale and independent testing history: the global giants ship far more panels and have longer public reliability records. If the biggest brand name gives you confidence, go JA Solar or Aiko; if a long warranty backed by UK support is what reassures you, Perlight is a genuinely smart pick.
Pros & cons
Pros
- Rare 30-year product and performance warranty
- Dedicated UK support centre in Oxford
- Modern N-type TOPCon cells at ~22–23% efficiency
- Strong low-light performance for UK conditions
- Compact formats suit awkward or smaller roofs
- Value-to-mid pricing; MCS-certified & SEG-eligible
Cons
- Not a top-three global brand name
- Thinner independent testing/track record than the giants
- Below premium panels (e.g. Aiko) on peak efficiency
- Confirm the exact warranty terms in writing on your quote
Our verdict
4.2 / 5 — an under-rated choice with a standout warranty. Perlight won’t win the badge-appeal contest against JA Solar or Aiko, and its global track record is shorter. But look past the brand recognition and you get modern, efficient panels, a market-leading 30-year warranty, and — crucially — a UK operation that actually stands behind them. For a decades-long investment, that combination of long cover and reachable UK support is worth a lot.
If you want maximum efficiency on a tricky roof, spend up on Aiko. If you want the biggest-scale value pick, look at JA Solar. But if long-term peace of mind is what you’re really buying, Perlight deserves a place on your shortlist.

Perlight solar panels: frequently asked questions
Are Perlight solar panels any good?
Yes. Perlight makes modern N-type TOPCon panels reaching around 23% efficiency, backs them with a rare 30-year product and performance warranty, and — unusually for the price — offers dedicated UK support from a centre in Oxford. They aren’t from a top-three global maker, but for a well-warranted, keenly-priced panel with real UK backup, they’re a solid choice.
Who makes Perlight solar panels and where are they based?
Perlight Solar was founded in 2006 and is a Chinese manufacturer backed by a group with manufacturing roots going back to the 1980s. What sets it apart in the UK is its own sales and customer centre in Oxford, so warranty and support are handled here rather than only through overseas distributors.
What warranty do Perlight solar panels have?
In the UK, Perlight panels are marketed with up to a 30-year product and 30-year performance warranty — among the longest available on any panel. That’s a genuine standout, though as always the warranty is only as good as the installer who fits them, so use an MCS-certified company.
How efficient are Perlight solar panels?
The current N-type TOPCon range reaches around 22–23% efficiency, with the bifacial double-glass 515W model at the top end. That’s very competitive and in the same bracket as JA Solar and Jinko, though below the premium back-contact panels from Aiko.
How much do Perlight solar panels cost in the UK?
Perlight sits in the value-to-mid price bracket. As a fitted system, a typical 4kW to 5kW array lands around £5,000 to £7,000 with 0% VAT until 31 March 2027. Per panel they’re priced with mainstream brands like Jinko, JA Solar and DMEGC — cheaper than premium names like Aiko or LONGi.
Perlight vs Aiko vs JA Solar — which is best?
Aiko leads on efficiency and is the pick for small or shaded roofs. JA Solar is the big-scale value benchmark. Perlight’s edge is the 30-year warranty and dedicated UK support — appealing if long-term peace of mind and being able to reach someone in the UK matter to you. On raw specs they’re similar to JA Solar; on aftercare Perlight arguably has the edge.
Figures are typical 2026 UK estimates for guidance only; efficiency, warranty terms and prices vary by exact model and installer, and headline warranty terms are those marketed in the UK — always confirm in writing on your quote. Always use an MCS-certified installer. 0% VAT on solar applies until 31 March 2027 per HMRC. Sources: manufacturer specifications and UK reviews.
