Sharp Solar Panels Review (2026): Are They Any Good?
Sharp was one of the original big names in solar, and it made panels in Wrexham for a decade. But its European solar arm, which supplied the UK, closed on 31 March 2025. This review covers what Sharp’s last panels were like, what the model codes on your roof or quote mean, what the exit means for your warranty, whether end-of-line Sharp stock is worth buying, and the best panels to choose instead.

Does Sharp still sell solar panels in the UK?
No. Sharp stepped back from Europe in two stages:
| Date | What happened |
|---|---|
| 2004 | Sharp starts making solar panels at its factory in Wrexham, North Wales |
| February 2014 | Wrexham panel production ends after European prices fall about 30% in two years. Sharp keeps selling panels in Europe, made elsewhere |
| 6 February 2025 | Sharp Energy Solutions Europe, its Hamburg-based solar arm, announces it will withdraw because of “difficult conditions in the European solar market” |
| 31 March 2025 | Sharp Energy Solutions Europe closes after 30 years. Sharp Electronics GmbH takes over warranties and customer service from 1 April 2025 |
Sharp Corporation, majority-owned by Foxconn since 2016, said the closure wouldn’t affect its other solar business outside Europe. For UK buyers, though, Sharp is no longer a brand being actively supplied. What you’ll see on the market is end-of-line stock held by distributors, and availability will only shrink.

Sharp NU-JC440 & NB-JG
★★★½☆ Good panels with warranties still honoured, but withdrawn from Europe
The bottom line: good panels, and a reassuring warranty set-up for owners. For a new install, though, a brand still in production is the safer choice.

Yes. Sharp was one of the pioneers of solar, and its panels had a solid reputation for quality on UK roofs from the Feed-in Tariff years onwards. Its final European range kept up with the market. The NU-JC440 was a 108 half-cell N-type TOPCon panel at 22.53% efficiency, the same technology and efficiency class as today’s mainstream Jinko and JA Solar panels. The NB-JG range added a dual-glass, bifacial build at 22–22.5%. For EU and several other markets, these came with a 25-year rooftop product guarantee and a 30-year power guarantee: 99% of rated output in year one and 87.5% in year 30.
Older Sharp panels on UK roofs are typically 175–300W models from the 2008–2015 era, many made in Wrexham. They’re less efficient than modern panels, at roughly 14–18%, but usually still generating well.
Sharp solar panel models and codes decoded
| Model | Cells | Power | Efficiency | Warranty (product / power) |
|---|---|---|---|---|
| NU-JC440 | N-type TOPCon, 108 half-cells | 440W | 22.53% | 25 yrs (EU rooftop, 12 yrs elsewhere) / 30 yrs, 87.5% |
| NB-JG440B / NB-JG450R | N-type TOPCon, dual-glass bifacial | 440–450W | 22.0–22.5% | 25 yrs (UK rooftop) / 30 yrs, 87.5% |
| NU-JC410B / NU-JC415B | Mono PERC, all-black | 410–415W | ~21% | 25 yrs from June 2023 / 25 yrs, 85% |
| NU-JD / NB-JD (540–580W) | Mono PERC, large format | 540–580W | ~21% | Mainly commercial and ground-mount |
| Older NU / ND series | Mono or poly | 175–300W | ~14–18% | 2008–2015 era, check your paperwork |
The quick read: NU is a monofacial panel, NB is bifacial, a final B usually means all-black, and the number is the wattage. If you’re offered end-of-line stock, the JC440 and JG codes are the modern TOPCon panels. JC410B, JC415B and JD are older PERC technology. See types of solar panels and bifacial panels.
Got a Sharp system that isn’t performing?
A vetted local installer can test the panels and inverter, help with a warranty claim, and price a repair, a battery or an upgrade. It’s free, with no obligation.
Check My Sharp System →What Sharp’s exit means for your warranty
This is the reassuring part. When it closed Sharp Energy Solutions Europe, Sharp said that “all product and performance warranties will remain valid for the duration of the warranty period”, and that they would be managed by Sharp Electronics GmbH from 1 April 2025. For UK owners, that means:
- Recent panels (2023–2025): a 25-year product guarantee and 25–30-year power guarantee should still apply. Keep the datasheet, invoice and MCS certificate, and check whether your panels were registered with Sharp.
- Older panels: shorter product guarantees from the 2010s (often 10 years) have probably expired, but a 25-year power guarantee may still run.
- How to claim: start with your installer, who’ll need to show the fault or underperformance, then contact Sharp Electronics. A power claim usually needs evidence such as a flash test.
The installer’s own workmanship guarantee covers the installation itself, and is often more useful in practice. See solar panel warranties explained.
Where are Sharp solar panels made?
It depends on the age of the panel. From 2004 to early 2014, many Sharp panels sold in the UK were assembled at Sharp’s factory in Wrexham, North Wales, with others from Japan. After Wrexham closed, Sharp’s European panels were made by manufacturing partners to Sharp’s specification, rather than in Sharp’s own factories, as most brands now do. Sharp Corporation is headquartered in Sakai, Japan, and majority-owned by Taiwan’s Foxconn.
Should you buy end-of-line Sharp panels?
Only if the price is clearly lower than an equivalent current panel. If an installer offers leftover Sharp stock:
- Check the model. NU-JC440 or NB-JG are modern TOPCon panels. JC410B, JC415B and JD are older PERC.
- Get the warranty in writing, with confirmation that it will be honoured by Sharp Electronics GmbH.
- Ask about replacements. If a panel fails in year 5, there may be no identical Sharp panel to swap in.
For most people, a current panel from a brand still in production is the simpler choice. Panels are a small part of a system’s cost, about £1,000 of a typical £5,500–£7,500 4kW install with 0% VAT, so the saving on end-of-line stock is rarely worth the trade-off. See solar panel cost UK.
Repairing, replacing or adding to a Sharp system
Inverter faults are the most common problem on older Sharp systems. A replacement costs £800–£1,500 (inverter replacement). A failed panel can be replaced with a current panel of similar voltage and current, ideally with an optimiser so it doesn’t drag down the rest of the string (optimisers). Adding a battery is the most popular upgrade, and an AC-coupled battery works with any existing system (add a battery). If you’re on the Feed-in Tariff, keep it, and tell your FiT supplier before changing anything that affects the generation meter. See repairs and servicing.
The best alternatives to Sharp solar panels
| If you wanted… | Look at | Why |
|---|---|---|
| A like-for-like TOPCon panel | Canadian Solar, Jinko, JA Solar | Same N-type TOPCon tech at about 22–23%, value prices |
| Dual glass, like the NB-JG | Trina (Vertex S+) | Dual-glass TOPCon, Kiwa PVEL Top Performer every year |
| Premium efficiency | Aiko | Back-contact cells, about 24%, strong shade tolerance |
| A long-established premium brand | REC | High-efficiency premium ranges, strong warranties |
| Another Asian-electronics name | Hyundai | Korean manufacturer with residential ranges |
Sharp isn’t the only big name to leave. LG left solar in 2022 and Bosch in 2013. Rankings across all brands: best solar panels UK.
Replacing Sharp, or comparing a Sharp quote?
A vetted local installer will price a current panel of the same size and technology, named in writing, with a ten-year workmanship guarantee.

Pros
- Last range used modern N-type TOPCon cells at 22–22.5%
- 25-year product and 30-year power guarantees on recent panels
- Warranties still honoured, via Sharp Electronics GmbH
- Long track record, including a decade of UK manufacturing
Cons
- Sharp’s European solar arm closed in March 2025
- Only end-of-line stock left, with patchy availability
- No guarantee of identical replacement panels in future
- Some remaining stock is older PERC technology
Verdict: are Sharp solar panels any good?
3.4 / 5. Sharp made good solar panels, right up to its modern TOPCon range, and owners are in a better position than with most departed brands, because Sharp Electronics GmbH still honours the warranties. But Sharp no longer supplies panels to the UK. If you have Sharp panels, keep them, look after the inverter and consider a battery. If you’re buying, pick a brand still in production. Canadian Solar, Jinko or JA Solar are the like-for-like choice, Trina if you want dual glass, and Aiko for premium. Choose the installer carefully (how to choose, MCS certification).

Sharp solar panels: frequently asked questions
Does Sharp still make solar panels for the UK?
No. Sharp Energy Solutions Europe, the Hamburg-based arm that supplied Sharp solar panels to the UK and Europe, closed on 31 March 2025, citing difficult conditions in the European solar market. Only leftover distributor stock remains. Sharp had already ended panel production at its Wrexham factory in 2014. Sharp says its solar business outside Europe is unaffected.
Are Sharp solar panels any good?
Yes. Sharp’s last European panels, the NU-JC440 and dual-glass NB-JG range, used N-type TOPCon cells at about 22–22.5% efficiency with a 25-year product guarantee and 30-year power guarantee. Older Sharp panels from the 2008–2015 era are less efficient but have a solid reputation. The drawback is that Sharp has withdrawn from Europe, so for a new install a brand still in production is usually the better choice.
Will Sharp still honour my solar panel warranty?
Yes. Sharp said that all product and performance warranties remain valid for their full term and are managed by Sharp Electronics GmbH from 1 April 2025. Keep your datasheet, invoice and MCS certificate, and start any claim with your installer. Shorter product guarantees on panels from the early 2010s may have already expired.
Where are Sharp solar panels made?
Many Sharp panels sold in the UK between 2004 and early 2014 were made at Sharp’s factory in Wrexham, North Wales, with others from Japan. After Wrexham closed, Sharp’s European panels were made by manufacturing partners to Sharp’s specification. Sharp Corporation is based in Sakai, Japan, and is majority-owned by Foxconn.
Can I still buy Sharp solar panels in the UK?
Only as end-of-line stock from distributors, and availability is shrinking. If you’re offered Sharp panels, check whether they’re the modern NU-JC440 or NB-JG TOPCon models or older PERC panels, and get the warranty confirmed in writing. For most homes, a current panel from Canadian Solar, Jinko, JA Solar, Trina or Aiko is the simpler choice.
What warranty do Sharp solar panels have?
Sharp’s last European residential panels, the NU-JC440 and NB-JG range, came with a 25-year rooftop product guarantee and a 30-year power guarantee of 99% in year one and 87.5% in year 30, in the EU and several other markets. The NU-JC410B and NU-JC415B had a 25-year product guarantee from June 2023 and 85% power after 25 years. Older panels usually had shorter product guarantees.
Sharp’s European exit and warranty arrangements are from Sharp’s February 2025 announcement as reported by pv Europe and pv magazine. Wrexham details are from PV Tech (December 2013). Specifications are from Sharp’s NU-JC440 product page and NB-JG and NU-JC410B/415B published terms. Older panel figures are typical for the era and vary by model. Prices are typical 2026 UK estimates with 0% VAT, which applies until 31 March 2027. Always confirm the model, datasheet and warranty with an MCS-certified installer.
