Solar Payback Period: How Soon Will It Pay Off? | EnergySage

Final calculation. To calculate your solar payback period, divide your combined costs by your annual savings. Combined costs ($20,670) / annual savings ($2,550) = solar payback period (8.1 years) In this example, your payback time would be 8.1 years, which is the average solar payback period for most EnergySage shoppers.

Energy Payback Time

3.3 Energy payback time (EPT) Energy payback time (EPT) is the time required for a generation technology to generate the amount of energy that was required to build, fuel, maintain and decommission it. The EPT is closely linked to the energy payback ratio and depends on assumptions made on the lifetime of a technology [59,70–73].
