Enter annual system kWh from measurements or power and runtime. Both scenarios share currency and period. Simple payback excludes interest, inflation, tax, degradation and residual value. Savings come entirely from your inputs.
How we calculate
annual = kWh/year × price + service/year; total = investment + years × annual; payback = (investmentB − investmentA) / (annualA − annualB)
