Savings depend on your system size, energy usage, and whether you add battery storage, but a typical Scottish household can see significant reductions.
Typical figures for a 5 kW system:
- Generation — around 4,000 kWh per year in Central Scotland
- Bill savings — £1,800–£2,100 per year, depending on how much you use directly and your electricity tariff
- Smart Export Guarantee — you get paid for surplus electricity you export to the grid
- Payback period — typically 5–7 years, after which the electricity is essentially free for the remaining 20+ year lifespan of the panels
Adding a battery increases your self-consumption significantly. Instead of exporting cheap surplus during the day, you store it and use it in the evening when tariffs are highest. This can push bill savings even higher.
We provide a free, no-obligation savings report based on your actual roof, energy usage, and tariff so you know exactly what to expect before committing.
