UK Solar Power Hits Record 14.4% of Electricity Generation; Plug-in Solar Panels Legalized in August

en.Wedoany.com Reported - In July 2026, solar power accounted for 14.4% of the UK's national electricity supply, setting a new historical record. The UK government is set to legalize plug-in solar panels from August 27, 2026, removing barriers for households to install photovoltaic equipment themselves.

Data from the UK's National Energy System Operator (Neso) shows that rooftop solar panels and ground-mounted solar farms together met 14.4% of national electricity demand that month, a 50% increase compared to the same period in 2025. The main drivers behind this surge were solar irradiance reaching twice the monthly average level, alongside continued growth in household solar panel installations.

Chris Hewett, Chief Executive of Solar Energy UK, stated that fifteen years ago solar power was merely a supporting player in the country's electricity mix, but it has now become a major source providing cheap, clean, and reliable electricity. Frankie Mayo, Senior Analyst at energy consultancy Ember, noted that the UK is experiencing the second wave of its solar boom, consistent with global trends, as households and governments increasingly view solar as a low-cost alternative to oil and natural gas.

UK government data also shows that the first half of 2026 was the highest six-month period for solar panel installations in fifteen years; total installations for the full year of 2025 reached 269,000 units, the highest ever recorded. The statistics include ground-mounted solar farms, and nearly one-third of the UK's total installed solar capacity comes from rooftop solar panels.

Despite the notable growth, the installation cost of traditional solar panels remains a barrier for many households. Through the Statutory Instrument 2026/848, the UK government has removed the legal obstacles preventing residents from purchasing and installing plug-in solar panels themselves. The regulation takes effect on August 27, 2026, though the specific launch dates for the kits have not yet been announced.

Plug-in solar panel kits are expected to be sold through retailers such as Lidl, Currys, and Amazon, priced at around £400, with a claimed annual saving of £70 to £110 on household electricity bills. Users simply plug the kit into a wall socket to use it, with no professional installation required.

This approach offers a new option for renters, apartment residents unable to install rooftop solar, and households constrained by traditional installation costs.

The legalization decision has been welcomed, though some argue it came too late. Had the policy been introduced a few months earlier, these devices could have contributed to the record-breaking generation figures in July.

In terms of the adoption of balcony solar panels (known as Balkonkraftwerk in German), the UK still lags behind Germany. The combination of record generation and the legalization of plug-in solar panels marks a shift for solar from a supplementary role in the electricity mix to a component capable of large-scale power supply.

This shift is also evident in several other countries, including Indonesia. With growing awareness of the importance of the clean energy transition and cheaper plug-in products entering the market, public access to renewable energy is expected to expand further.
