Solar panels in Portsmouth: a local intro

Portsmouth is one of the sunniest cities in mainland Britain and a strong residential solar market — particularly across Cosham, Drayton, Farlington and Southsea. Coastal-grade mounting is standard.

Why solar works well in Portsmouth

Portsmouth records 1,800+ sunshine hours and 1,080-1,100 kWh/kWp annually.

The benefits of solar panels

A modern residential solar system cuts your electricity bills from day one, insulates you against future energy-price rises, reduces carbon emissions, and (with the Smart Export Guarantee) pays you for any surplus power you send to the grid. With a 25-year panel performance warranty, you'll generate clean energy for two decades after the system has paid for itself.

Solar battery storage

Adding battery storage to a Portsmouth solar install typically lifts self-consumption from around 35% to 75-85%, dramatically cutting the amount of expensive grid electricity you import in the evening. Combined with a smart tariff like Octopus Flux, a properly sized battery can save a further £400-£900 per year — typically paying back in 7-10 years.

EV charger installation

More Portsmouth households now charge an electric vehicle from home than ever before. A solar-aware charger (Zappi, Hypervolt, Ohme) lets you fuel many of your summer miles from excess solar generation — effectively at 0 p/kWh.

Typical property types in Portsmouth

Victorian terraces dominate Southsea, Eastney and central Portsmouth; 1930s semis and bungalows in Cosham and Drayton.

Solar costs in Portsmouth

Standard 4 kWp installs from £6,500; bungalow installs often go larger for excellent value.
