Solar Energy Savings in Scotland

How Solar Reduces Your Electricity Bills

The calculations below show how your electricity bills change with solar.

What drives your savings in Scotland

Scotland receives the UK’s lowest solar irradiance at around 780–860 kWh/kWp, with the central belt (Glasgow, Edinburgh) performing better than the Highlands. However, very long summer days — up to 18 hours of daylight in June — boost seasonal output significantly. Electricity rates of 24–34p/kWh apply nationally, and Scotland’s slightly different building regulations can affect installation requirements. The combination of high retail tariffs and 0% VAT means the savings case remains positive, particularly for homes with good south-facing exposure.

Your usage & system size Scotland

Energy usage & tariffs

Scottish homes often use 10–20 kWh/day with high winter heating load. Coastal vs inland microclimates vary slightly; efficiency matters year-round.

Reducing baseload helps right-size PV and battery.

Representative flat export rate (feed-in tariff). What you earn per kWh of surplus solar exported to the grid. Your actual rate depends on your provider, plan, and time of day.

Estimated at 75% of the retail grid rate. A battery lets you store daytime solar and export during expensive peak hours, so each exported kWh is typically worth more than a flat feed-in tariff. Real returns depend on your time-of-use tariff and battery efficiency.

Solar system size

About 3.9kW matches typical consumption; size up if you expect EV or heat pumps. 5.9kW–7.9kW is a common design band.

5.9 kW averages ~20.8 kWh/day with pronounced summer peaks.

1 kW 20 kW

A 6 kW system in Scotland can generate approximately 7718.0 kWh annually based on local sun conditions.

Battery storage

Solar-only self-use ~45%; 55% grid. Batteries store summer excess for darker months — valuable in northern latitudes.

Some suppliers now offer wholesale-linked or time-of-use export tariffs, paying significantly more for electricity exported during peak demand hours (typically 4–7pm) than the standard flat SEG rate. With a battery, you can store daytime solar and export at these higher rates, or simply use it yourself during peak pricing.

The sweet spot for most households is 5 – 13 kWh — larger batteries add independence but with diminishing payback, especially where feed-in tariffs are low.
