Clean energy for the capital — solar solutions designed for London’s unique rooftops
London might not be the first place you think of for solar panels, but the capital is one of the fastest-growing solar markets in the UK. Over 2,100 London homes already have solar installations, with boroughs like Waltham Forest, Tower Hamlets, and Greenwich leading the way. The city receives around 1,500 hours of sunshine per year — comparable to Surrey and Essex — and with some of the highest electricity bills in the country, the financial case for going solar in London is compelling.
London’s housing stock is diverse: Victorian and Edwardian terraces across South and East London, Georgian townhouses in the centre, post-war estates, and modern apartment blocks. Each presents different solar opportunities. Terraced houses with south-facing rear roofs are ideal candidates — a compact 8–10 panel system can cover the majority of a household’s electricity needs. Flat-roofed extensions and loft conversions offer additional mounting options. Even properties with limited roof space can benefit from high-efficiency 515W+ panels that generate more power per square metre.
Lunar Solar serves all London boroughs, from Bromley and Croydon in the south to Barnet and Enfield in the north. We understand the challenges of urban installations — scaffolding access on narrow streets, working within conservation area restrictions in places like Greenwich and Hampstead, and coordinating with freeholders for leasehold properties. Our compact, high-output systems are designed specifically for London’s space constraints, and every installation is backed by our MCS certification and full warranty package.
London receives as much sunshine as many South East counties, making solar a genuinely productive investment in the capital.
London households pay some of the highest energy rates in the country, meaning solar savings are proportionally greater.
