Executives from several major UK retailers have engaged in discussions with government officials to explore the launch of plug-in solar panels designed for flats and rented homes. Representatives from Currys, B&Q, Amazon, Asda, Screwfix, and Wickes met with Martin McCluskey, the minister for energy consumers, to review guidelines for selling these "balcony solar panels" to British households.

The government’s aim is to enable more residents, particularly those without access to rooftops, to generate their own electricity and reduce energy costs. The initiative aligns with a broader strategy to increase domestic renewable energy capacity as part of a transition towards a low-carbon power system by 2030.

Plug-in solar panels, already popular in countries like Germany and Spain, can be connected directly into a standard household electrical socket. This allows the electricity generated to be used immediately within the home, offsetting power drawn from the grid. In Germany, it is estimated that approximately 1.5 million balconies feature such devices, known locally as Balkonkraftwerk or “balcony power plants.”

McCluskey emphasized the potential impact of these panels for renters and lower-income households, highlighting their ease of installation and affordability. “This easy-to-install tech can cut people’s bills and help make the UK less reliant on global fossil fuel markets,” he said.

In the UK, the renewable energy sector has seen rapid growth, with a record 269,000 solar installations completed last year—a 36% increase over the previous year. The government’s energy secretary, Ed Miliband, has set ambitious targets to increase the UK’s solar capacity from 18 gigawatts (GW) currently to between 45GW and 47GW by the end of the decade, enough to power roughly 12 million average UK homes.

Retailers involved in the talks have expressed commitment to ensuring the safety, compliance, and ease of installation of the new solar products. Graham Bell, CEO of B&Q, noted the company’s collaboration with the government and suppliers to help shape product guidelines, aiming to make plug-in solar panels available to customers promptly.

Typically, plug-in solar systems have a capacity of around 800 watts, considerably less than traditional rooftop panels but sufficient to reduce household electricity consumption. When connected, solar power is prioritized before grid electricity, potentially saving an average household between £70 and £110 annually. Market prices for these systems are expected to start at about £400, suggesting a payback period of four to seven years, according to government analysis.

The introduction of plug-in solar panels represents a step toward making renewable energy more accessible to a broader segment of the UK population, particularly those in flats or rental properties who previously faced barriers to adopting solar technology. The government expects these devices to become available in stores within the coming months.
