Solar & Batteries in Haddington

Why Haddington works for solar

Around 14% of homes in East Lothian already generate their own power — one of the highest rates in Britain. That matters twice: it proves panels work here, and it makes Haddington 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.

Solar is scaling up locally too: Scottish Water has filed plans for a 480-panel, 220 kWp array at Haddington’s waste water treatment works (East Lothian Courier, April 2026).

Scotland is the only part of the UK with interest-free loans and grants for home solar and batteries, plus 0% VAT 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 Haddington producing 3,720 kWh a year is worth roughly £440–£730 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.

What else you get

• Export income — sell spare units back on a Smart Export tariff.
• 0% VAT on panels and batteries until 2027.
• Price-rise shelter — your roof’s output never gets a cap announcement.
• EV-ready — daytime charging from your own power.
• Backup — with a battery, keep essentials on through outages.
