What Drives Solar Value in Scotland
Quick answer
This page explains the factors that shape the return from solar panels in Scotland, so you can understand any figures in your quote. We do not publish general payback promises, because results depend on your roof, usage and tariff. We install through MCS-certified partners across Scotland.

This page explains the factors that shape the return from solar panels in Scotland, so you can understand any figures in your quote. We do not publish general payback promises, because results depend on your roof, usage and tariff.
Generation
How much your panels generate depends on roof direction, pitch, shading and location. The north of Scotland has long summer days but very short winter ones.
Self-use and export
Electricity you use directly avoids buying it from the grid. Exported electricity is paid at your Smart Export Guarantee rate, which varies by supplier.
Costs and tariffs
The full price of the system, any finance costs, and your import tariff all matter. A battery can increase self-use but adds to the upfront price.
Calculator results are estimates based on the figures you enter and general assumptions. They are not a quote. Your written quote after a no-obligation survey shows the full price and the expected generation for your roof.
Solar on Scottish roofs
Scottish roofs vary more than most. Sandstone tenements in Glasgow and Edinburgh often have natural slate on steep pitches with valley gutters and rear slopes facing back greens. Granite houses in Aberdeen and the north-east frequently have dormers and chimneys that cast shade. Interwar and post-war council-built homes usually have concrete interlocking tiles that are straightforward to work on, while newer estates around Livingston, Dunfermline and Inverness tend to have simple gable roofs that suit a neat array.
Fixings are chosen for the roof covering and for the wind exposure of the site, which matters on the west coast, in the islands and on high ground. A survey also checks the roof timbers and slate condition before any panels go up, because it is far easier to fix a roof problem before an installation than afterwards.
How our survey works
Every project starts with a no-obligation survey. We look at your roof orientation, pitch, shading and condition, your fuse board and meter position, where a battery or inverter could go, and how your household uses electricity through the day and across the Scottish seasons. You then receive a written quote showing the equipment, the expected generation for your roof and the full price, so you can compare it fairly. We handle the network connection paperwork with your local distribution network operator, which is SP Energy Networks in central and southern Scotland and SSEN in the north, Highlands and islands. We install through MCS-certified partners. Solar panels and batteries are 0% VAT until March 2027. Finance available, subject to status.
