Understanding Solar ROI
Federal Tax Credit (ITC)
The Investment Tax Credit allows you to deduct 30% of solar installation costs from federal taxes through 2032. It steps down to 26% in 2033 and 22% in 2034.
Panel Degradation
Solar panels typically degrade 0.3-0.5% per year. Quality panels are warranted to produce at least 80% of rated output after 25 years.
Electricity Rate Trends
US electricity rates have historically increased 2-3% annually. Higher rate increases improve solar ROI as your locked-in savings grow over time.
Net Metering
This calculator assumes full retail credit for excess production. Check your utility's net metering policy, as some offer reduced credits.
