Are solar panels a good idea for a Scottish home?

For many homes, yes. Panels generate from daylight rather than heat, so they work in Scottish conditions, and they reduce how much electricity you buy. They suit homes best with a reasonably unshaded roof facing south, east or west and steady daytime or evening electricity use.

They are less suitable for heavily shaded or north-facing roofs, or roofs that will need replacing soon. A survey will tell you honestly whether your home is a good fit.

How much do solar panels cost?

For a typical Scottish house, a 3 to 4 kWp system usually costs in the region of £5,000 to £8,000 fully installed (typical, subject to survey). Adding a battery increases the price. Your written quote will set out exactly what is included.

What grants or support are available in Scotland?

Scottish Government-backed grants and loans may be available, subject to eligibility; we'll check what applies to you. Solar panels and batteries installed in homes also currently qualify for 0% VAT, which is scheduled to run until 31 March 2027, so the saving is built into your quote.

Do I get paid for the electricity I export?

Yes. Under the Smart Export Guarantee, participating electricity suppliers pay you for surplus electricity you send to the grid. You need an MCS certificate for your system to apply. Rates and terms vary between suppliers, so compare offers before you sign up.

Do I need planning permission?

Usually not. Most roof-mounted solar on houses in Scotland is covered by permitted development rights. Listed buildings, conservation areas and some flats can need consent from your local council, and this is checked before installation so there are no surprises later.

Frequently asked questions

Sometimes, but you will normally need consent from your local council first. Panels on a rear roof slope that cannot be seen from the street are more likely to be accepted. We can talk through the options before you apply.

It is sensible to let your buildings insurer know that solar panels have been fitted. Most insurers simply note it on your policy, but check whether it changes your cover or premium.

The panels stay with the property. Pass your MCS certificate, warranties and other documents to the buyer, and let your export tariff supplier know so payments can be transferred to the new owner.

Yes, with a solar diverter. If you have a hot water cylinder with an immersion heater, a diverter sends surplus solar electricity to heat your water instead of exporting it to the grid.
