Frequently asked questions
Frequently asked questions
Are the results binding?
No. This is an initial model. Roof condition, shade, grid, local tariffs, incentives and quotations may change the result.
Why is the calculator not on the home page?
This keeps the home page faster and clearer. The complete calculator is loaded only on this dedicated page.
Can I send the result to PHT?
Yes. A project enquiry with the calculated figures can be prepared below the result.
Would you like to know what is possible for your property?
Your address, annual consumption and photos of the roof, meter cabinet and plant room are enough for an initial assessment.
