Estimate only. Your survey confirms roof space, shading, and local tariffs.
How we calculate it
Your bill is converted to yearly usage at the tariff above.
The system is sized to cover most of that usage, up to a typical roof limit.
Yearly output uses average peak sun hours and standard system losses.
Payback divides the installed price by the yearly savings.
Questions
About your estimate
How accurate is the estimate?
It is a fair starting point for a typical roof. Shading, roof direction, and your local tariff can move the real numbers up or down, so your survey and quote confirm them.
Why is my system size capped?
Most home roofs fit up to about 10 kWp. Larger homes, businesses, and farms often have more space, and we size those systems during the survey.
Does the estimate include a battery?
No. The figures cover panels only. A battery lets you use more of your own power in the evening, which raises savings but also the price. We model both in your quote.
Are grants or incentives included?
No. Incentives change by region and over time. Your quote lists any that apply to you and shows the price before and after them.
