From August 27, plug-in solar panels will be available on UK supermarket shelves for the first time, following a law change under Prime Minister Andy Burnham's Labour government. The move legalises the devices, which have been banned in the UK until now, and allows households to generate their own electricity using 'balcony solar panels'.
The legislation, passed last month, means people across the country can join millions in Europe who already use these panels. However, experts are warning that improper use could pose a safety hazard.
Safety warnings from experts
Matt Parry, head of power and energy demand at the Renewable Energy Association, highlighted the benefits but stressed the importance of safety. "Plug-in solar panels are an amazing way for all of us around the UK to get access to clean, cheap, renewable energy, but it's crucial that we understand how to use them most safely," he said.
Parry warned against using extension leads, explaining: "Extension leads are designed to send power out, not take it in, and the wiring inside could get dangerously hot if attached to a solar panel." He also noted that window frames often have sharp metal edges that can erode cables, and rain entering through open windows can damage electrics.
He advised: "The safest option is to plug the solar panel directly into an outdoor socket with an IP rating of 66 or above – this means it's completely dust-tight and protected against water coming from every direction."
Industry welcomes the change
The government's decision is expected to bring "cheap, clean power to households that have not been able to access these benefits before," according to Chris Hewett, chief executive of Solar Energy UK. He added: "Our industry is working closely with government to ensure that all customers can have confidence in the safety and reliability of these new technologies."
Rob Hallifax, co-founder of Windfall Energy, also addressed the rule change. "For renters, flat owners and anyone on a budget, this opens up clean energy in a way we haven't seen before," he said. However, he cautioned that households should set "realistic expectations" for their new solar setup.
Practical considerations for households
Hallifax pointed out that the timing of the law change means generation will naturally decline as autumn and winter approach. "Coming into force in late August means generation will naturally decline as we head into autumn and winter," he said. He also reminded potential users that they need access to a sunlit balcony, terrace or suitable outdoor area, and may require permission from a landlord or freeholder.
The panels, which are popular in countries like Germany and the Netherlands, allow renters and flat owners to generate renewable energy without installing full rooftop systems. With the law change, UK households can now take advantage of this technology, but experts urge caution to ensure safe installation and use.
