Plug in Solar Panels Announcement - We Look At What The Realistic Savings Might Be

17th June 2026

Retailers join government plans to bring plug-in solar panels to UK homes, helping families save money on bills.

B&Q and Currys join government plans to bring plug-in solar to UK homes.

Rooftop solar panels are already saving families up to £480 a month.

Government launches consultation for industry views on ensuring consumer safety.

More families are set to save money on bills as flagship retailers Currys, B&Q, Amazon and Lidl join government plans to bring plug-in solar panels to UK homes.

At a roundtable of some of the biggest retailers in the country, with a combined total of almost four thousand stores and significant online presence, Minister for Energy Consumers Martin McCluskey discussed the crucial role of plug-in solar in the clean energy revolution.

Those in attendance included Amazon, Asda, B&Q, Currys, Screwfix and Wickes, who discussed the technology and how it can offer a cheaper route for people to save money on bills.

This follows rule changes announced by the government earlier this year that will allow UK homeowners to self-install plug-in solar panels in the coming months and builds on savings of up to £480 consumers can already make from rooftop panels.

Minister for Energy Consumers Martin McCluskey said, "Plug-in panels can be transformative for renters or those on lower incomes, so I welcome the conversation today with household names such as B&Q and Currys showing a huge amount of support for getting the panels in people’s homes.

This easy to install tech can cut people’s bills and help make the UK less reliant on global fossil fuel markets.

John Boumphrey, UK & Ireland Country Manager, Amazon said, "This is a fantastic opportunity to make renewable energy more accessible to people around the UK. Amazon is the largest corporate buyer of carbon-free energy in the UK – we’ve invested in over 40 large scale solar and wind projects to date.

Enabling households to generate their own power with self-install plug-in solar panels is a practical step that supports household budgets and delivering against net zero goals.

Graham Bell, CEO of B&Q, said, "We welcome the introduction of plug-in solar panels to the UK market, which will help households to generate their own energy and reduce their bills. This builds on our existing range of portable solar and battery solutions.

We are working closely with government and suppliers to understand and help shape the guidance, ensuring any products we offer are safe, compliant and straightforward to install. We look forward to making plug-in solar available to our customers as soon as possible.

Georgina Hall, corporate affairs director at Lidl GB, said, "At Lidl GB, we want to make sustainable choices affordable and accessible to every household which is why we are supporting DESNZ’s latest steps toward modernising regulations for ‘plug-and-play’ technology.

By establishing a clear, robust framework to bring plug-in solar to market safely and efficiently, it could unlock a highly effective, low-cost route for people to reduce their energy bills. We welcome this consultation and look forward to working alongside the government and industry partners to explore how these products can safely play their role in the UK’s clean energy revolution.

Michelle Gorringe-Smith, Director of New Categories at Currys, said, "We’re delighted to be working with DESNZ to bring plug-in solar panels to the UK market. With energy bills continuing to rise, enabling the safe roll-out of these products will mark an important step for consumers across the UK - including the more than 80% of UK households that shop at Currys.

This technology, already widely used by households throughout Europe, is easy to install and could save many households significant amounts on their energy bills, while helping make the UK less reliant on global fossil fuel markets.

The low-cost panels can be put on balconies or in any outdoor space, providing free solar power that can be used directly through a mains socket like any other device, without an installation cost, thereby reducing the amount of electricity taken from the grid.

Alongside the roundtable, the government has today (Tuesday 16 June) launched a consultation seeking industry views on enforcing the rules so consumers can safely install plug-in panels in their homes.

Households across Britain are already embracing solar power in record numbers. 2025 saw a record 269,000 solar installations completed in the UK - the highest total ever recorded in a calendar year and 37% larger than the year before.

Around 255,000 of these were rooftop solar - meaning at least 95% of all new solar was installed on homes, businesses and other buildings. This equates to a new rooftop solar installation every two minutes throughout 2025.

Plug‑in Solar Panels: What They Really Save
The UK Government’s announcement about “plug‑in solar panels” sounds like a breakthrough: cheap, simple, no electrician needed, instant savings. But the real question is the one you’re asking, Bill — how much money do they actually save, and how many do you need before it makes a real difference?

Let’s break it down using realistic numbers, not marketing optimism.

What a typical plug‑in panel produces
Most UK plug‑in kits are:
300–400W per panel
£250–£350 each
Plug into a normal 13A socket

Generate 250–350 kWh per year in Scotland (lower than England due to latitude)

That means:

A 400W panel produces roughly 1 kWh per sunny summer day, less in winter.

Annual output in Wick/Aberdeen latitude: 250–300 kWh is realistic.

What that means in savings
Using the current electricity price cap (around 22–24p per kWh):

One panel saves ~£55–£70 per year

Two panels save ~£110–£140 per year

Four panels save ~£220–£280 per year

That’s the maximum saving — and only if you use the electricity as it’s generated.

[b]The catch: you only save if you’re using power at the same time
Plug‑in panels don’t export to the grid unless you have a smart export tariff and the right meter.
Most households lose unused generation, because it simply flows back into the grid unpaid.

So the savings depend on:

Being home during the day

Running appliances when the sun is out

Avoiding exporting unused power for free

A retired couple at home all day will save more than a working family out 9–5.

So how many panels do you need to “make a real difference”?

Here’s the honest version:

One panel
Barely noticeable.
Saves £5–£6 a month in summer, £1–£2 in winter.

Two panels
Useful but still modest.
Covers the background load of a fridge, router, standby devices.
Saves £10–£12 a month in summer.

Four panels
This is the point where you start to feel it.
Covers daytime base load + some appliance use.
Saves £20–£25 a month in summer.

Six to eight panels
Now you’re into “meaningful difference” territory.
Saves £300–£500 a year depending on usage.
But at this point you’re spending £1,500–£2,000 — close to a small fixed solar installation.

Payback time
Typical payback periods:

One panel: 5–7 years

Two panels: 5–6 years

Four panels: 4–5 years

Six+ panels: 4–6 years depending on tariff and usage

These are optimistic and assume you use most of the generated power.

Realistic expectations for Scotland (especially the Highlands)
Scotland’s latitude means:

Winter output is very low

Summer output is good

Cloud cover reduces annual yield

North-facing gardens or shaded areas reduce savings further

For Wick, Thurso, Inverness, Aberdeen — the realistic annual output is 20–25% lower than southern England.

So the savings are real, but modest.

Plug‑in solar panels are a helpful, low‑cost way to shave a bit off your bill — but they are not a game‑changer.

To make a real difference:

You need at least 3–4 panels

You need to be home during the day

You need to avoid exporting unused power for free

You need a south‑facing, unshaded location

They’re a good idea for some households, but the press release oversells the impact.
