Solar panel cost calculator
in under 60 seconds.
Enter your postcode, a rough roof size and how you use energy. The calculator suggests a system size, panel count and battery, then models annual generation, bill savings, Smart Export Guarantee income, CO₂ avoided and payback using UK figures. You do not need to sign up to see the results.
Where is your property?
Your postcode tells us how much sunlight your area receives. Nothing you enter is stored unless you ask us to get in touch.
Tell us about your roof.
Larger, south-facing roofs generate the most. A typical UK semi has 30–50 m² of usable roof, so a rough figure is fine. We measure it properly at survey.
How do you use energy?
The more electricity you use during the day, the more of your solar generation you use yourself. An electric car or a heat pump can change the figures considerably.
Your preferences.
Your answers shape the recommendation and the payback figures. Nothing is fixed: you can change your mind at survey.
