Estimate solar savings, electric bill savings, monthly savings, annual savings, lifetime savings, solar payback period, net system cost, incentives, return on investment, and solar production value. Use this calculator to compare solar system cost against expected electricity savings.
Solar production mode:
The calculator multiplies monthly solar kWh production by your electric rate and export credit to estimate monthly and annual savings.
Monthly bill mode:
The calculator uses your current electric bill and solar offset percentage to estimate how much of your bill solar may reduce.
System size mode:
The calculator estimates solar production from system size, peak sun hours, and system losses, then estimates savings from that production.
Payback and ROI mode:
The calculator compares estimated net solar cost against yearly savings to estimate payback period, lifetime net savings, and return on investment.
A solar savings calculator helps estimate whether a solar system may be worth the cost before comparing quotes, planning a project, or estimating long-term energy savings.
It can help compare monthly savings, annual savings, lifetime savings, net system cost, incentive value, solar payback period, ROI, system production, electric bill offset, and avoided utility costs.
Your result shows estimated monthly solar savings, first-year annual savings, lifetime gross savings, lifetime net savings, net system cost, incentive value, payback period, ROI, monthly production value, annual production value, and projected savings with utility rate increases.
Multiply solar kWh production by your electric rate and export credit. Then compare yearly savings against the net cost of the solar system.
Solar payback period is the number of years it may take for energy savings to recover the net cost of the solar system.
Incentives, rebates, and credits reduce the net cost of the solar system, which can shorten the payback period and increase ROI.
If electricity prices rise over time, the value of solar savings may increase because each kWh produced by solar offsets more expensive electricity.
No. This is an estimate. Actual savings depend on utility rates, net metering rules, system production, equipment performance, financing, taxes, incentives, maintenance, and local policy.
