For years, residential solar power in the UK has focused primarily on larger installations, comprising photovoltaic (PV) panels on the roof and an inverter for converting DC (direct current) power into AC (alternating current) for use in the home. Indeed, according to government data, the UK now has approximately 1.7 million residential rooftop installations with 2025 the strongest year on record with around 269,000 installations completed.
It’s remarkable progress. Yet for many in the UK, this type of installation remains out of reach for several reasons, including cost, or lack of roof access if they live in a block of flats. If they’re renting, their landlord/landlady might not allow them to install solar panels permanently on the roof.
