Solar panels in Southampton: a local intro

Southampton's combination of high sunshine hours, mixed urban housing and a substantial student / shared-occupancy rental market makes it a varied solar market — from compact 3 kWp city installs to 8 kWp arrays on Bassett and Highfield detached homes.

Why solar works well in Southampton

Southampton records 1,750+ sunshine hours and around 1,070 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 Southampton 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 Southampton 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.
