Interactive comparison
Compare solar surplus with your own assumptions.
The calculator presents scenarios transparently. It is not a quotation, tax advice or a guarantee of returns.
Enter annual surplus that is genuinely available, tariff values and technical assumptions. The tool estimates the annual gross value of different uses. Investment, life, finance and project-specific losses need a separate assessment.
Frequently asked questions
Frequently asked questions
Why does it show gross value?
To avoid distorting the comparison with generic hardware costs. An investment decision needs actual quotations and expected life.
How accurate is the mining scenario?
It is a scenario input only. Revenue and equipment conditions change; use conservative, current figures.
What is heat utilisation?
The share of waste heat that genuinely replaces another heat source. Unused summer heat is not a benefit.
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.
