Dunbar solar guide: yields, costs and the Home Energy Scotland route
Solar in Dunbar is shaped as much by the local housing stock and council attitude as by sunshine hours. With suitability rated 5/5 and access to Home Energy Scotland interest-free loans of up to £12,000, the right install on the right roof in East Lothian produces a dependable, multi-decade return.
Is solar worth it in Dunbar?
For most Dunbar homeowners with a south, southeast or southwest-facing roof of at least 18 m², solar in 2026 produces a strong, predictable return. With local sunshine averaging 1490 hours per year and a yield of around 870 kWh per kWp, a standard 4kWp install saves about £695 a year and pays back in roughly 9.9 years.
The economics tighten meaningfully for households with daytime occupancy, EV charging or a heat pump — these homes routinely consume 55–70% of generated electricity directly rather than exporting it at SEG rates, compressing payback below 7.9 years.
Where solar makes less sense in Dunbar: heavily shaded north-facing roofs, properties with major chimney or tree obstructions, short-tenure private rented sector flats, and households without the daytime base load to absorb summer generation (which makes a battery the deciding factor).
