Sharp Solar Panels Review: NU-JD Range, Status & Warranty
Sharp is one of the oldest names in solar. The Japanese electronics giant began researching solar cells in 1959 and started mass production in 1963, powering everything from satellites and lighthouses to some of the first residential rooftop systems. For decades Sharp panels were a familiar, trusted sight on UK roofs.
There is an important catch in 2026, though. Sharp closed its European solar business on 31 March 2025 and no longer sells solar panels in the UK or Europe. You can still buy remaining Sharp NU-JD stock from some distributors, and Sharp continues to run an after-sales and warranty service team, but the brand is effectively discontinued here. This guide covers the Sharp range, what the exit means for buyers and existing owners, and the alternatives worth considering instead.
Quick Answer
Sharp is a pioneering Japanese solar manufacturer (PV research since 1959, mass production from 1963) whose panels were widely fitted in the UK. However, Sharp closed its European solar division on 31 March 2025 and no longer sells panels in the UK or Europe. Remaining NU-JD mono PERC half-cut stock (around 400–580W, e.g. NUJD550 550W and NBJD580 580W) is still available from some distributors, with a 15-year product warranty and 25-year performance warranty to roughly 80.7% of rated output. Sharp still runs an after-sales and warranty service team in Europe. Because the brand has exited the market, most buyers in 2026 are better served by a current N-type TOPCon or back-contact panel from LONGi, Aiko, Jinko, JA Solar or DMEGC, which carry live warranties and ongoing UK supply.

Important: Sharp has left the European solar market
On 6 February 2025, Sharp announced it would withdraw from the European solar business, and Sharp Energy Solutions Europe ceased trading on 31 March 2025. Sharp cited the difficult conditions in the European solar market, where a flood of low-cost modules has squeezed margins for everyone. The decision ended more than 30 years of Sharp selling solar panels in Europe.
In practical terms this means Sharp no longer manufactures or supplies new panels to the UK channel. What remains is existing distributor stock of the NU-JD range and a Sharp after-sales service team that still handles warranty claims, technical support and documentation for panels already installed.
If you already own Sharp panels
Your panels keep working exactly as before. The product and performance warranties remain valid and are administered through Sharp’s European after-sales service. Keep your install paperwork, MCS certificate and serial numbers in case you ever need to make a claim.
If you are considering buying
You can still find new-old-stock Sharp NU-JD panels from some UK distributors, often at a discount. They are perfectly good panels, but you are buying into a brand that has left the market, so weigh the warranty-support risk against a current brand with ongoing UK supply.
Sharp NU-JD technology: mono PERC half-cut cells
Sharp’s last residential and commercial range, the NU-JD series, uses monocrystalline PERC cells in a half-cut configuration with a 10-busbar layout. This was solid, mainstream technology for its time, though it sits a generation behind the N-type TOPCon and back-contact cells that dominate the 2026 market. For a primer on how these cell types compare, see our guide to solar panel types.
PERC Cells
PERC (Passivated Emitter and Rear Cell) adds a reflective layer to the back of the cell to capture more light. It was the dominant cell technology of the late 2010s and early 2020s, now being replaced industry-wide by more efficient N-type TOPCon.
Half-Cut Cells
Splitting each cell in two halves the current per cell, reducing resistive losses and improving performance under partial shade. It also lowers the risk of hot spots. Sharp paired this with a 10-busbar design to lift output and reliability.
Build Quality
Sharp panels earned a reputation for solid manufacturing and reliable real-world output, reflecting the company’s decades of PV experience. The engineering was never the problem; the brand simply could not compete on price as the market commoditised.
How NU-JD compares to today’s panels
The NU-JD range is mono PERC, which tops out around 20–21% module efficiency. Current N-type TOPCon panels from Jinko, JA Solar, Trina and DMEGC reach roughly 22–22.5%, and back-contact panels from LONGi (HPBC) and Aiko (ABC) reach 23–24%+. On a small UK roof that efficiency gap matters, because higher-efficiency panels fit more capacity into the same space. Sharp’s panels are perfectly capable; they are just a generation behind the newest options.
Who makes Sharp solar panels and where are they made?
Sharp solar panels are made by Sharp Corporation, the Japanese electronics company founded in 1912 and headquartered in Sakai, Osaka. Sharp is now majority-owned by Foxconn (Hon Hai Precision Industry). The company was a genuine pioneer of photovoltaics, beginning solar cell research in 1959, reaching mass production in 1963, and supplying solar power for satellites, lighthouses and early residential systems long before solar was mainstream.
Solar heritage
- 1959: Began photovoltaic cell research
- 1963: Started mass production of solar cells
- 1976: Supplied solar cells for the Ume satellite
- Long history powering lighthouses and remote sites
- One of the world’s longest-running PV makers
- Held global module shipment lead in the mid-2000s
Company background
- Parent: Sharp Corporation (Japan)
- Founded: 1912 (electronics); solar from 1959
- Headquarters: Sakai, Osaka, Japan
- Majority owner: Foxconn (Hon Hai) since 2016
- European solar division closed 31 March 2025
- After-sales and warranty service still active
Sharp’s solar cells and modules were produced at Sharp facilities in Japan and, at various times, contract and overseas plants serving European demand. With the European division now closed, no new Sharp modules are being supplied to the UK; the panels still on sale here are remaining distributor stock.
Sharp panel range: NU-JD and NU-JC series
Sharp’s final lineup centred on the NU-JD high-power series for residential and commercial roofs, plus all-black NU-JC residential panels for buyers who wanted a uniform black aesthetic. The exact models still findable in UK distributor stock vary, but the table below covers the representative range. All use mono PERC half-cut cells.
Sharp panel variants
| Model | Cell tech | Wattage | Efficiency | Appearance |
|---|---|---|---|---|
| NBJD580 (NB-JD) | Mono PERC half-cut | 580W | ~21.4% | Silver frame |
| NUJD550 (NU-JD) | Mono PERC half-cut | 550W | ~21.3% | Silver frame |
| NU-JD540 | Mono PERC half-cut | 540W | ~20.9% | Silver frame |
| NU-JC410B | Mono PERC half-cut | ~400–410W | ~20.5% | All-black |
The higher-wattage NU-JD and NB-JD panels (540–580W) are larger commercial-format modules, while the all-black NU-JC (~400–410W) is the residential-friendly option. Because Sharp has exited the market, exact stock and model availability now depend entirely on what individual distributors have left.
Specifications are based on Sharp datasheets and distributor listings and vary by model and batch. With Sharp’s European site now an after-sales portal, confirm the exact model, wattage and warranty terms with the distributor before buying any remaining stock.
How much do Sharp solar panels cost in the UK?
Because Sharp panels are now end-of-line stock, pricing is less predictable than for a current brand. Some distributors discount remaining inventory to clear it, while genuinely scarce models can hold their price. As a rough guide, Sharp NU-JD panels sell for around £90–£180 per panel depending on wattage and stock, putting them in the mid-range. A full installed system is what matters most; for broader UK pricing context, see our solar panels cost guide.
| System Size | Number of Panels | Estimated Cost (installed) | Cost per Panel |
|---|---|---|---|
| 3.5 kW | 8–9 panels | £5,000–£6,500 | £90–£180 |
| 5 kW | 11–13 panels | £6,500–£8,500 | £90–£180 |
| 7 kW | 15–17 panels | £8,500–£11,000 | £90–£180 |
0% VAT on residential solar installations
Sharp solar panels still qualify for 0% VAT when supplied and installed on residential properties in the UK, because the zero rate applies to the installation, not the brand. It covers panels, inverters, batteries and mounting equipment installed under the same contract, and is in effect until at least March 2027.
Prices are estimates based on UK distributor listings in 2026 and the cost of a comparable installed system. Actual costs vary by installer, stock availability, location, roof complexity and inverter/battery selection. Always obtain multiple quotes and confirm exactly which panel is being supplied.

Sharp NU-JD panels carry a 15-year product warranty and a 25-year performance warranty, guaranteeing at least 97.5% of rated output in year one and no more than ~0.7% degradation per year thereafter, reaching a minimum of around 80.7% of rated output at year 25. These terms remain valid and are administered by Sharp’s European after-sales service, but the brand exit adds a genuine consideration that did not exist before.
| Warranty Type | Duration | Details |
|---|---|---|
| Product warranty | 15 years | Covers manufacturing defects in materials and workmanship |
| Performance warranty | 25 years | Guarantees ~80.7% of rated output at year 25 |
| First-year output | – | At least 97.5% of nominal power |
| Annual degradation | – | Maximum ~0.7% per year |
The warranty risk to understand
A 25-year warranty is only as good as the company standing behind it. Sharp Corporation itself is a large, long-established business and continues to run a European after-sales service for solar, so claims can still be made today. The honest caveat is that a warranty stretching to the 2040s now depends on Sharp maintaining that support for a product line it has exited. By comparison, the product warranty length itself (15 years) is already shorter than the 25-year product warranties standard on current panels from LONGi, Jinko, JA Solar and others. Keep all your documentation and route any claim through your installer or Sharp’s after-sales portal.

Sharp solar panels: pros and cons
Sharp panels are well engineered and have a long track record, but the brand’s exit from the European market reshapes the decision for any new purchase. Here is the balance for a UK buyer in 2026.
Pros
- Pioneering heritage – one of the longest-running solar makers in the world, with proven real-world reliability
- Solid build quality – Sharp panels earned a strong reputation for manufacturing standards
- Often discounted – remaining stock can be cheaper than current-generation panels
- After-sales still active – Sharp continues to run a European warranty and support service
- Half-cut design – better shade tolerance and lower hot-spot risk than older full-cell panels
Cons
- Brand has left the market – Sharp exited European solar on 31 March 2025, so there is no new supply
- Long-term warranty uncertainty – a 25-year guarantee on a discontinued line is a genuine risk to weigh
- Older cell technology – mono PERC, behind current N-type TOPCon and back-contact panels on efficiency
- Shorter product warranty – 15 years vs the 25 years standard on current brands
- Patchy availability – stock and model choice now depend entirely on individual distributors
Sharp solar panels FAQ
Does Sharp still make solar panels?
Sharp Corporation closed its European solar division, Sharp Energy Solutions Europe, on 31 March 2025 and no longer sells solar panels in the UK or Europe. It announced the withdrawal in February 2025, citing difficult conditions in the European market. Remaining NU-JD distributor stock can still be bought, and Sharp continues to run an after-sales and warranty service, but the brand is effectively discontinued here.
Are Sharp solar panels any good?
Yes, Sharp panels are well engineered and reliable, backed by one of the longest histories in solar (PV research from 1959, mass production from 1963). The NU-JD range uses mono PERC half-cut cells with good real-world output. The main drawback in 2026 is not the panel quality but the fact that Sharp has exited the European market, which affects new supply and long-term warranty confidence.
Why did Sharp stop selling solar panels in Europe?
Sharp cited the challenging conditions in the European solar market. A flood of low-cost modules, mostly from large Chinese manufacturers, has driven prices and margins down to the point where Sharp could no longer compete profitably. Sharp Energy Solutions Europe ceased trading on 31 March 2025 after more than 30 years.
Should I still buy Sharp solar panels in 2026?
You can, but for a new install most buyers are better off with a current brand. Sharp's remaining stock can be cheaper, but you get older mono PERC technology, a shorter 15-year product warranty, and a brand that has left the market. Current N-type panels from LONGi, Aiko, Jinko, JA Solar or DMEGC offer higher efficiency, 25-year product warranties and ongoing UK supply. Sharp may still suit a budget project where stock is heavily discounted.
What happens to my Sharp solar panel warranty?
Existing Sharp warranties remain valid. Sharp continues to operate a European after-sales service team that handles warranty claims, technical support and documentation for panels already installed. The NU-JD range carries a 15-year product warranty and a 25-year performance warranty to around 80.7% of rated output. Keep your install paperwork, MCS certificate and serial numbers in case you need to claim, and route any claim through your installer or Sharp's after-sales portal.
What is the Sharp NU-JD range?
NU-JD is Sharp's high-power monocrystalline PERC half-cut panel series, with a 10-busbar cell design. It spans roughly 400W to 580W, including the NUJD550 (550W) and NBJD580 (580W) silver-frame commercial-format panels and the all-black NU-JC residential panels around 400–410W. All use mono PERC cells, which sit a generation behind current N-type TOPCon and back-contact panels on efficiency.
How efficient are Sharp solar panels?
Sharp NU-JD panels reach roughly 20–21.4% module efficiency, typical for mono PERC. That is solid but behind current N-type TOPCon panels (around 22–22.5%) and well behind back-contact panels from LONGi and Aiko (23–24%+). On a small roof the difference matters because higher-efficiency panels fit more capacity into the same space.
Who makes Sharp solar panels?
Sharp solar panels are made by Sharp Corporation, the Japanese electronics company founded in 1912 and headquartered in Sakai, Osaka. Sharp has been majority-owned by Foxconn (Hon Hai) since 2016. The company pioneered photovoltaics from 1959 and supplied solar for satellites and lighthouses, but closed its European solar division in March 2025.
What is the best alternative to Sharp solar panels?
For a current install, LONGi (mainstream to premium back-contact), Aiko (highest residential efficiency), DMEGC (value N-type TOPCon) and Panasonic (Japanese heritage) are all strong replacements. They offer newer cell technology, 25-year product warranties and ongoing UK supply, which a discontinued Sharp panel can no longer match.
How much do Sharp solar panels cost in the UK?
As end-of-line stock, Sharp NU-JD panels typically sell for around £90–£180 per panel depending on wattage and availability, sometimes discounted to clear inventory. A full installed system of any brand at 3.5–5 kW costs roughly £5,000–£8,500 including 0% VAT. Confirm exactly which panel is being supplied, as Sharp stock and pricing now vary by distributor.
Do Sharp solar panels qualify for 0% VAT and SEG?
Yes. The 0% VAT rate on residential solar applies to the installation, not the brand, so a Sharp install by an MCS-certified installer still qualifies, as does the Smart Export Guarantee (SEG) for selling surplus electricity back to the grid. SEG rates vary by supplier but typically range from 3–30p per kWh in 2026.
