68% of Britain’s Solar Panels Come From China — Here’s What That Actually Means for You

That number is real, the headlines are loud, and the word “security” is being thrown about like confetti. I’ve spent a fortnight digging through trade data, parliamentary debates and cyber-security rulebooks so you don’t have to. Here’s the plain-English truth — no panic, no sales pitch.

68% of Britain's Solar Panels Come From China — Here's What That Actually Means for You
Most of the panels on British roofs began life on a Chinese production line — and that’s by design, not accident.

0%of the world’s solar wafers were made in China in 2023

📊Where does the 68% number come from?

The 68% estimate has been cited in Parliament itself — a June 2026 Hansard record of a Commons debate on Chinese-manufactured solar panels put the figure at 68%, alongside a striking related stat: two-thirds of NHS trusts are also dependent on Chinese solar. It’s a significant jump from the “more than 40%” figure that was widely reported back in April 2025, when the government first moved to block forced-labour-linked panels from Great British Energy’s supply chain — a sign of just how quickly Chinese import share has grown in little over a year.

Key takeaway: Whether the precise figure is 40% or 68% at any given moment, the supply chain is deeply entwined with China, regardless of the brand badge on the panel — China accounts for more than 80% of global manufacturing capacity across polysilicon, wafers, cells and finished modules.

🛡️What is the actual security risk?

Politicians talk about panels being “switched off” remotely. This is technically impossible for a standard solar panel. The risk lies entirely in the smart inverters and monitoring apps that connect your roof to the internet.

The PSTI Act: Since April 2024, the UK’s Product Security and Telecommunications Infrastructure Act requires all consumer connectable products to meet baseline security standards (unique passwords, update policies).

⏳How did we get here?

April 2025 “Over 40%” Reported

HMRC-sourced reporting around GB Energy’s forced-labour policy put Chinese import share at “more than 40%”.

April 2024 PSTI Act Enforced

UK law mandates baseline security for all smart home gadgets, including solar inverters.

March 2026 2 Million Installations

The UK hits a historic milestone, passing 2 million solar installations (22.1GW total capacity), confirmed by GOV.UK.

23 April 2026 Record Generation

Solar output hit a record 15.42GW on Britain’s grid, per National Energy System Operator data.

June 2026 68% Cited in Parliament

Hansard records the updated 68% estimate during a Commons debate on Chinese-manufactured solar panels.

💸The cost of avoiding Chinese panels

If you want to avoid Chinese brands, you will pay a premium. But does it buy you security? No. Almost all non-Chinese brands still use Chinese wafers.

❌Myths vs Reality

Myth
China can switch off your panels
Reality

Panels are hardware. They cannot be hacked remotely. Only smart inverters have connectivity.

Myth
Non-Chinese panels are 100% China-free
Reality

Almost all panels use Chinese silicon wafers, even if assembled elsewhere.

Myth
Solar apps are dangerous
Reality

They are as safe as any smart thermostat. Just change your default passwords.

✅Your 5-point security checklist

🔒
Change Default Passwords

Update your inverter’s app and admin panel with a strong, unique password.

📶
Use Guest Wi-Fi

Put your inverter and monitoring hub on a separate network from your main devices.

⬆️
Update Firmware

Check for inverter updates quarterly to ensure you have the latest security patches.

🛡️
Use MCS Installer

Ensure your installer is MCS-certified and configures the system securely.

❓Frequently Asked Questions

Are Chinese solar panels safe to put on a UK home in 2026?
Yes. A solar panel is glass, aluminium and silicon — it has no software, no radio and nothing to hack, so it cannot be ‘switched off’ remotely. The genuine security conversation is about smart inverters, monitoring apps and grid-scale equipment, and consumer connectable products sold in the UK must already meet baseline security rules under the Product Security and Telecommunications Infrastructure (PSTI) Act. Buy through an MCS-certified installer and your setup is as safe as any smart home device.
Should I pay extra for non-Chinese solar panels to avoid the risk?
Not for security reasons, no. Swapping Chinese brands such as Jinko or JA Solar for non-Chinese brands like REC or SunPower Maxeon adds roughly £500–£1,000+ to a typical 10-panel array, and almost every panel on the market — whatever the badge — still uses Chinese wafers or cells, so you’d be paying for a logo rather than true independence. A properly specified 4kW system should still land between £6,000 and £8,500 installed with a 7–11 year payback.
Can my solar inverter or monitoring app be hacked?
The realistic risk for a domestic system is low and is the same kind of risk as any smart home gadget. Since 29 April 2024, the UK PSTI Act requires consumer connectable products to have things like unique passwords and proper security updates. Keep your inverter’s firmware updated, change default passwords, put the monitoring hub on a guest Wi-Fi network and never expose it directly to the internet — that’s the whole job done.
