Oban solar panel advice — 2026 prices, payback and grant eligibility
Oban sits at ~1230 sunshine hours per year and delivers a working yield of around 750 kWh per kWp installed — comfortably enough to make a well-sited 4kWp system pay back in roughly 12 years. This page covers what an install actually costs in Argyll & Bute in 2026, which grants apply, and how the local installer market behaves.
Is solar worth it in Oban?
In Oban, the solar case rests on three numbers: ~750 kWh per kWp of annual yield, £585 of typical annual savings on a 4kWp system, and 12 years to break even. After that, the system continues producing energy for 15–20 years of pure return.
What lifts the case from "decent" to "exceptional" is the combination of HES interest-free finance, zero-rated VAT until March 2027, and Scottish electricity prices that have remained stubbornly above pre-2022 levels — meaning every kWh self-consumed offsets a more expensive import.
Oban households where solar struggles to justify itself: very low electricity users (under 2,000 kWh/year), homes with extensive shading from neighbouring buildings or mature trees, and short-tenure private rentals where the homeowner won't see the savings.

Local housing & roof types
Oban's hillside layout creates strongly south-facing rear roofs on many properties — better suited to PV than the orientation alone suggests.
Predominant roof type: Granite seafront terraces, modern detached on the hillside.
Climate & solar yield in Oban
