What are plug-in solar panels – and how do they work?
Plug-in solar panels - also known as plug and play solar or balcony solar - are small solar kits designed to be incredibly easy to use:
- Place them on a balcony, terrace, shed roof or outdoor space
- Connect the plug-in solar inverter into a standard 3 pin socket
- Start generating your own electricity, which you can use instantly to power your home – so you don’t need to buy as much electricity from the grid
This means plug-in solar panels particularly suited to:
- Renters
- Flats and small homes
- Balconies and small gardens
- Anyone wanting a low cost, low commitment way to start generating clean energy
The government has greenlit some changes to wiring regulations, which’ll mean that systems under 800W can plug safely into domestic sockets without needing an electrician. This is expected to go live from summer 2026. And retailers such as Lidl are already preparing to bring plug-in solar panels to the UK.
Why introduce plug-in solar panels in the UK?
Plug‑in solar panels are a low‑cost, flexible way to start generating renewable electricity. And they’re already popular across Europe - over 426,000 balcony solar system were registered in Germany alone in 2025.1
The UK Government sees plug-in solar panels as key to:
- Reducing our reliance on volatile fossil fuel and vulnerability to energy market fluctuations
- Increasing the UK’s energy security
- Cutting household energy bills
- Accelerating clean, home grown power
Is plug‑in solar worth it?
Plug‑in solar panels can be a great option if you want to:
- Cut energy bills without spending too much
- Plug-in and go without a time-consuming installation
- Avoid long term commitment
- Complement existing smart home or renewable tech
- Start small and upgrade over time
Plug-in panels won’t power your home alone - but they can meaningfully reduce how much electricity you need to buy during the daytime.

How British Gas is supporting the move to plug‑in solar panels
British Gas is already preparing the smart tariffs, services and customer support needed to help households benefit fully from plug‑in solar panels and other clean technologies.
“Plug-in solar and home batteries are a real breakthrough for customers - making greener, cheaper energy something you can simply plug-in and start benefiting from straight away,” explains John Evans, Commercial Director, British Gas Energy
“Simple, low‑cost plug-in panels are a huge opportunity for people to take more control of their energy bills.
At British Gas, we’re already building the compatible tariffs and smart services that make this effortless. We’re helping customers use more of their own clean solar power, store it intelligently, and cut their grid use at the most expensive times.
And it fits perfectly with PeakSave, giving customers even more ways to lower their bills by shifting usage and making the most of cheap, clean power.
This is exactly the kind of practical, affordable progress we believe in: helping people save money today while supporting the UK’s move to clean, home‑grown energy.”
What does the Future Homes Standard (FHS) mean for households?
The FHS is one of the biggest changes to home energy in over a decade. Under current proposals, most new homes are expected to be built with:
- Solar panels as standard
- Low‑carbon heating, such as a heat pump as well as proper home insulation
- At least 75% lower predicted carbon emissions compared to 2013 standards1
- Significant energy savings, expected to save families up to £830 per year compared to a typical EPC C home1
As a result, most new build homes will generate their own electricity, use clean heating, and be designed for smart optimisation from day one.
As the UK’s biggest installer of low‑carbon heating, we welcome these announcements, including the Future Homes Standard,” says Chris O’Shea, CEO of Centrica. “It’s a chance to ensure new homes come ready for the full benefits of modern energy systems - where low‑carbon heating, solar and smart technology are designed to work together from the start and reduce energy consumption. Our army of engineers stand ready to continue to keep Britain's homes warm.
Discounted electricity on windy days
Alongside plug‑in solar panels, the Future Homes Standard introduces a new approach where, instead of paying wind farms to switch off when the grid is full, households can benefit from discounted energy on windy days. This’ll primarily benefit:
- Scotland
- The East of England
This fits neatly alongside British Gas’s existing PeakSave Green Flex events, where customers are rewarded for shifting their energy usage to times when more renewable power is available.
Frequently Asked Questions
What are plug-in solar panels?
Plug‑in solar panels are small solar systems that generate electricity and plug directly into a home’s mains socket. They’re a simple, low‑cost way to reduce grid electricity use during daytime.
How do plug-in solar panels work?
They generate electricity from sunlight, convert it into usable power via a built‑in microinverter, and feed it into your home’s circuits through a mains plug. Any appliances running at the time use that free solar energy first.
When will plug-in solar panels be available in the UK shops?
The UK government has announced that plug‑in solar panels will be available in UK shops within months with major brands preparing to stock them once new regulations are introduced.
Plug-in solar panels are set to become one of the simplest ways for households to cut their energy bills - and the government has announced that plug‑in solar panels will be available in UK shops within months.
Are plug-in solar panels legal in the UK?
They will be once the Government updates safety and connection rules to allow up to 800W of plug‑in solar capacity. These changes are expected as part of new regulations coming into force this summer.
Do I need an electrician to install plug-in solar panels?
No. Plug‑in solar panels are designed for DIY installation and simply plug into a standard socket. Always follow manufacturer instructions and safety guidance.
Do plug-in solar panels really save money?
Yes, plug‑in solar panels can help lower energy bills by reducing the amount of daytime electricity you buy from the grid. Savings are highest for homes using more power during daylight hours.Actual savings depend on home type, usage patterns and installation conditions.
How much could I save on my energy bills?
Savings vary by home and usage. Plug‑in systems reduce the amount of electricity you buy from the grid, especially during daylight hours.
How do plug-in solar panels differ from rooftop solar?
They’re smaller, cheaper and plug directly into a socket. Rooftop solar produces more power but requires professional installation.
Do you need smart meters for plug-in solar panels?
While not strictly mandatory for plug-in solar panels to function, a smart meter (specifically an import/export meter) is highly recommended for plug-in solar panels. Smart meters accurately measure exported energy for payments, ensure safe grid compliance, and allow you to take advantage of time-of-use tariffs.
How much energy can plug-in solar panels produce?
An 800W kit can typically generate a meaningful amount of electricity across the year - enough to reduce bills, but not equivalent to a full rooftop system. Output depends on panel size, orientation, weather and shading.
Are plug-in solar panels safe?
Yes, the Government is updating the G98 distribution code and BS 7671 wiring regulations to ensure UK‑specific safety rules for plug‑in solar panels. These include built‑in protections to prevent overload or back‑feed.
Can I export excess electricity back to the grid?
Plug‑in solar panels are designed mainly for using what you generate. Future rules may evolve, but initially the focus is on making the technology simple, safe, and accessible.
