What is this tool used for?
Use this comparison to estimate total spending if you continue with grid electricity versus installing solar and still paying a remaining grid bill.
How to use this calculator
Enter the current bill, expected bill after solar, installation cost, maintenance, comparison years, tariff growth and degradation assumptions. Add replacement expenses where relevant and keep all amounts in one currency.
Understanding your results
Compare cumulative costs over the same period. The solar option includes its upfront investment and ongoing bills, so savings are not the same as eliminating the electricity bill. Financing and the time value of money are not modelled.
Како се пресметува
Пред да го користите резултатот
All monetary inputs must use the same currency. Assumes the tariff escalation applies to the entire modelled bill; fixed charges and time-of-use rates may behave differently. No financing, discounting or export revenue is included separately.
Can the solar option cost more?
Yes. High upfront costs, low savings, maintenance or a short analysis period can make solar more expensive in this scenario.
