British households will be able to install plug-in solar panels from August 27, following a government legal change. These "balcony solar panels," already common in Europe, can be plugged into a standard socket, offering a DIY solution for generating electricity from balconies, terraces, or shed roofs. Retailers like Currys, B&Q, and Asda will offer these setups, which are expected to cost around £400 and could reduce annual energy bills by up to £110.

This move aims to provide affordable, clean energy to households previously unable to access solar benefits, such as those in flats or rented homes. Chris Hewett of Solar Energy UK stated it brings "cheap, clean power to households that have not been able to access these benefits before." The plug-in systems, typically 800-watt capacity, can help lower bills, with payback estimated in four to seven years.

The legislation also opens possibilities for plug-in batteries, potentially aiding low-income homes in managing energy costs by storing surplus electricity. Rob Hallifax of Windfall Energy highlighted this as a "massive win for consumer energy independence," making clean energy accessible for renters, flat owners, and budget-conscious individuals. However, users are advised to manage expectations regarding generation, especially heading into autumn and winter, and to secure landlord permission if necessary.
