UK Shops to Stock Plug-in Solar Panels After Rule Change

The government says the panels could help households cut energy bills by up to £110 a year, but safety experts urge buyers to check their wiring first.

Plug-in solar panels are arriving in DIY shops and High Street retailers after the government changed the rules to allow them to be sold legally in the UK. They are significantly cheaper than roof panels, can be installed without an electrician and suit properties with outdoor space, including some balconies.

Argos will stock the products from Thursday, and the government expects other shops to follow. It hopes the panels will help households save money and reduce reliance on overseas fuel sources, whose prices have moved up and down in recent months because of the Middle East conflict.

According to the UK solar company UKSOL, a one-panel kit will cost £699 and a two-panel kit £1,089. The government expects prices to settle at £400-£600 as competition increases, and its research shows a household could save between £70 and £110 a year. The exact saving depends on where the panels face and how long they run; an unshaded south-facing spot is best.

Output to the home is limited to 800 watts by a microinverter, which turns the current from the panel into electricity homes can use. The government says this should power about a fifth of an average household's electricity use while the sun is shining. British Gas said the panels will not power a home on their own but can "meaningfully reduce how much electricity you need to buy during the daytime".

Government tests found that sample systems could operate with no unacceptable heating or unsafe energy flows. However, the charity Electrical Safety First recommends having electrics checked by a registered electrician before buying, especially in older properties. Households must also tell their Distribution Network Operator within 28 days of plugging a panel in.
