Solar & battery in Cardigan: the local numbers

Why Cardigan works for solar

Around 19% of homes in Ceredigion already generate their own power — one of the highest rates in Britain. That matters twice: it proves panels work here, and it makes Cardigan 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.

Ceredigion sits in the UK’s top five areas for household solar according to the Energy Saving Trust’s hotspot analysis — your neighbours got there first.

Welsh households also have the Nest scheme for eligible homes, plus 0% VAT on panels and batteries UK-wide.

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 Cardigan producing 3,899 kWh a year is worth roughly £460–£760 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.
