China solar export shift: what it means for UK panel costs
Chinese customs figures show fewer module exports after the VAT rebate ended. Here is what that means for solar quotes in the UK.
Short answer: nothing in the reports gives a reason to rush a solar order or to hold off. Module exports from China have dropped, but the reports say nothing about UK prices. A typical 6 kWp system currently costs £12,500, with most mid-range quotes landing in £9,800 – £16,300, including VAT. Your own quote matters far more than this headline.
What has been reported
According to energynews.pro, Chinese customs figures for September 2026 were relayed by the press on 18 October. They show module exports falling while exports of solar cells are growing. The site notes that it could not confirm the detailed tables in a primary document, so the figures should be treated with some caution.
The background, as the site describes it:
- China has removed the VAT export rebate on photovoltaic products. The rebate used to refund exporters for tax paid upstream.
- Foreign buyers brought orders forward ahead of the deadline, and the last month before it set a monthly record for solar exports.
- Afterwards, monthly module exports fell back to a much lower level. Exports are down on last year over the year to date, though the site says part of the drop reflects an unusually high comparison base.
- Cell exports are up over the same period. This fits with more cells being sent to assembly hubs outside China, where they are made into modules.
- China's customs authority says photovoltaic exports are still rising over nine months, so the sources do not tell one story. The site adds that figures from different analysts do not always match.
The report also points to US tariffs and trade investigations, India's approved-manufacturer list and Chinese technology controls as other forces shaping trade flows.
What it could mean for your quote
We can only say so much from one month of customs data. The report covers exports to the world, not prices paid by UK installers, and it gives no price forecast. Here is how we would read it for a homeowner.
Panel prices are only part of the bill. Our solar costs are built from labour hours multiplied by local rates, plus materials, then checked against market prices and real quotes. Modules are one line. Scaffolding, inverter, mounting, electrical work, commissioning and the installer's margin make up the rest. A change in module trade flows would move the total by less than a change in any of those.
Shifting trade routes can take time to reach the roof. If more modules are assembled outside China, that changes who sells to whom. It does not tell us what a UK installer pays. We will watch our cost model and update the live figures here as the market moves.
Batteries are priced separately. If you want storage, the choice of battery changes the total more than anything in this story. For a 6 kWp system with a 10 kWh battery, our typical mid-range cost is £15,600. Without a battery it is £9,500. The full comparison is below.
| Material | Typical | Usual range | Lifespan |
|---|---|---|---|
| No battery | £9,500 | £7,400 – £12,300 | – |
| 5 kWh battery | £12,500 | £9,800 – £16,300 | – |
| 10 kWh battery | £15,600 | £12,200 – £20,300 | – |
| 13.5 kWh battery | £17,800 | £13,800 – £23,100 | – |
The UK incentive that matters more
The government's 0% VAT rate on installing energy-saving materials, including solar panels and batteries, runs until 31 March 2027. Our figures include 20% VAT except where 0% applies. If your installation will be done and invoiced before that date, check that your quote reflects the 0% rate. Ask what happens if the job slips past it.
The Warm Homes Plan, published in January 2026, commits £15bn to 2030. That includes grants for low-income households and low- or zero-interest loans that are being phased in. If you may qualify, it is worth looking at before you sign anything.
How to protect yourself
- Get at least three itemised quotes, with module brand, panel count, inverter and battery listed separately.
- Ask where the price comes from. An installer who blames "the Chinese market" for a high figure should show you the actual module line.
- Check the electrical side. Notifiable electrical work in England and Wales must be done by a registered electrician (Part P) or notified to building control.
- Compare against a neutral benchmark. Our "is my quote fair" tool lets you test a quote against our live model. If it sits well outside the range, ask why.
Our view
The September figures are interesting for the industry, but they are not a reason to change your plans. Pay more attention to the VAT deadline, to what each quote includes, and to whether a battery makes sense for how you use electricity.
