Frequently Asked Questions
How is solar payback period calculated?
Payback period is the net system cost (after incentives) divided by your annual electricity bill savings, showing how many years until the system pays for itself.
What is a good solar payback period?
Most homeowners see payback periods between 6 and 12 years, after which the system produces essentially free electricity.
Does this account for panel degradation or rising utility rates?
No, this is a simplified estimate assuming constant monthly savings. Actual payback may be shorter due to rising utility rates or longer due to panel degradation.
