Is Solar a Good Investment?
For most U.S. homeowners, solar panels deliver a 10–20% annual return on investment — significantly better than a savings account or even many stock market investments, when you factor in the guaranteed electricity savings and rising utility rates.
The 30% Federal Tax Credit
The Residential Clean Energy Credit reduces your federal tax bill by 30% of your solar installation cost. On a $20,000 system, that's $6,000 off — bringing your net cost to $14,000. This credit is available through 2032 and does not have an income cap.
Factors That Affect Solar ROI
- Electricity rates: Higher rates = faster payback
- Net metering: Full-retail net metering maximizes ROI
- Financing: Cash purchase returns more than a loan
- System size: Sized to your actual usage avoids over/under-building
- Panel quality: Better panels degrade slower (0.3–0.5%/yr)
