Cost guide · Solar PV

What solar panels actually cost in Scotland.

From the quotes we write, not a comparison site’s lead form. A typical 4 kWp system on a Fife home lands between £6,000 and £9,000 fitted, and this guide explains what puts you at either end — and why the “from £3,750” adverts are for a different system.

On site for a typical home

The headline: a typical Fife home

Most of the systems we install across Fife are around 4 kWp — ten or so panels, a 5 kW hybrid inverter, the scaffolding, the roof fixings, the isolators and cabling, commissioning, and the MCS certificate, DNO notification and electrical certificates filed for you. Fitted, that is £6,000 to £9,000 as a fixed price after a free survey.

Where you land in that range is mostly about the roof and the kit, not about haggling. A straightforward concrete-tile semi with easy access and standard black panels sits near the bottom. Slate, in-roof panels, three storeys of scaffold, shading that needs optimisers, or a premium panel choice move you up.

What moves the price

Every quote we write is itemised, so you can see which of these apply to your house. Roughly in order of how often they come up:

Common reasons a solar quote moves up or down
ItemEffect on a 4 kWp quoteWhen it applies
Scaffold for a third storey or awkward access Up Townhouses, rear roofs over conservatories, tight lanes
Slate roof or in-roof (integrated) panels Up Slate needs hooks and care; in-roof replaces tiles and costs more in labour
Optimisers for shading Up Chimneys, dormers, trees — worth it when part of the array is shaded
Hybrid inverter instead of string Up slightly Battery-ready from day one; we fit these by default unless you rule a battery out
Premium or all-black panels Up slightly Mostly appearance and a small efficiency gain
Bird-proofing mesh Up slightly Sensible under panels near gulls and pigeons
Consumer-unit upgrade Up Older boards without Type A RCD protection; quoted as a fixed line
Fewer panels Down — but not in proportion Scaffold, inverter and paperwork cost the same, so small systems cost more per kW

Adding a battery

A 5–10 kWh home battery takes the combined total to £10,000–£14,000. Whether it earns its place depends on when you use electricity: solar-only systems typically self-consume 30–40% of what they make, because the roof works hardest at midday and the house works hardest in the evening. A battery moves that daytime surplus to the evening, and on a time-of-use tariff it can also charge cheaply overnight.

It does not shorten the payback much — it roughly doubles the yearly saving and roughly doubles the cost. What it buys is evening self-sufficiency, less exposure to price rises, and backup if you specify it. We model it against your consumption data and tell you plainly if it is not worth it for you.

Why the comparison-site figures are lower

You will see “from £3,750” and similar. Those are real prices for a different job: usually a 2–3 kWp system, a string inverter, no scaffold assumed, and the paperwork or the battery-readiness left off. The site showing you the figure does not install anything — it sells your details to several installers, some of them ours to compete against.

We quote one fixed, itemised, capped price after we have seen the roof. If something genuinely unexpected turns up during the work we stop and talk — we do not add it to the bill.

VAT, grants and what is actually available

Solar panels, batteries and their installation are zero-rated for VAT until 31 March 2027. On a typical quote that is worth around £1,500 compared with standard-rate VAT — a genuine saving, but a tax rate, not a grant, and it is already in the prices above.

There is no general grant or loan for solar or batteries open in Scotland at the moment. Home Energy Scotland stopped funding them in June 2024. Anyone telling you otherwise is either out of date or selling something. If that changes we will say so the week it does.

Payback, honestly

There is no honest single payback figure for Scotland; it depends on your roof, your consumption, your tariff and the export rate you can get. We work it out for your house with the assumptions written down. For a worked example with real Fife generation figures, read the companion guide.

FAQ

Frequently asked

Why do you quote per system rather than per panel?

Because most of the cost is not the panels. Scaffold, inverter, fixings, labour and certification are broadly the same whether you fit eight panels or twelve, so a per-panel price would mislead you. We quote the whole job, itemised.

Is the survey free?

Yes. We look at the roof, the consumer unit, the cable route and your consumption, and you get a written quote with an expected annual generation figure. No obligation.

Does the price include scaffolding and the paperwork?

Yes. Scaffold, the MCS certificate, the DNO notification to SP Energy Networks and the electrical certificates are all in the fixed price. You sign once for the Smart Export Guarantee application; we do the rest.

Can I start with solar and add the battery later?

Yes. We fit a hybrid inverter by default so a battery can be added later without changing it, or an AC-coupled battery can be added to any existing system. Adding later costs a little more than doing both at once, mostly in labour.

Is a smaller, cheaper system better value?

Usually not. The fixed costs do not shrink, so a 2.5 kWp system costs far more per kilowatt than a 4 kWp one. If your roof can only take six panels we will say so, but we will not sell you a small system to hit a price point.

Do you offer finance?

Ask us when you enquire — the options change. What we will not do is dress up a loan as a grant.
