The British government has approved legislation enabling households to purchase plug-in solar panels for the first time, with major retailers including Currys, B&Q, and Asda set to begin selling the systems from 27 August. These compact solar devices, which have already become common in European countries such as Spain and Germany, can be connected directly to standard three-prong wall sockets and installed on balconies, terraces, or other outdoor spaces without requiring professional installation.
Unlike traditional rooftop solar systems, plug-in panels offer an accessible option for people living in flats or rented properties who lack rooftop access. The devices are anticipated to retail for at least £400 and can reduce household energy bills by up to £110 annually. With a typical capacity of 800 watts—approximately one-fifth the size of conventional residential solar systems—they cannot power a home independently but can meaningfully decrease grid electricity consumption. Payback periods for these systems are estimated between four and seven years.
The policy change aligns with increased adoption of renewable energy solutions among British households. A record 269,000 solar installations were completed in the previous year, representing a 34 percent increase from the year prior. Industry representatives view the legislation as particularly beneficial for consumers who have previously been excluded from renewable energy benefits, including renters and those with limited budgets. Chris Hewett, chief executive of Solar Energy UK, emphasized that the move would provide affordable clean energy to households previously unable to access such technologies.
Government and industry discussions also centered on establishing safety and reliability guidelines for the new products. Looking forward, the legislation may facilitate future regulatory frameworks for plug-in battery systems, which could enable households to store renewable electricity for use during evening hours or when solar generation is lower. However, industry experts advise prospective buyers to maintain realistic expectations, noting that installations beginning in late August will experience declining generation as autumn and winter approach.
