Solar & battery in Totnes: the local numbers

Why Totnes works for solar

Around 20% of homes in South Hams already generate their own power — one of the highest rates in Britain. That matters twice: it proves panels work here, and it makes Totnes one of the UK’s best places to add a battery to existing solar, because most of those systems went in before home batteries were affordable.

South Hams is England’s top area for household solar — installs here keep climbing, and Totnes has been ahead of the energy curve for decades.

0% VAT applies to panels and batteries UK-wide, and the £7,500 Boiler Upgrade Scheme covers heat pumps if you’re electrifying heating too.

What the sums look like

At the current capped electricity rate of 26.32p/kWh (Ofgem, Oct–Dec 2026), a well-sited 4 kW system in Totnes producing 4,285 kWh a year is worth roughly £500–£840 a year in avoided imports, depending on how much you use as it’s generated — batteries push you toward the top of that range. Export payments add more on top.
