Understanding Your Solar ROI
The average U.S. homeowner can expect to break even on their solar investment in 6-9 years (Source: EnergySage 2025 Market Data), with systems lasting 25-30+ years. This means you could enjoy 15-20 years of free electricity after payback.
Key ROI Factors:
1. System Cost (Average: $2.50-$2.70 per watt installed)
- 6 kW system: $15,000-$16,200 before incentives
- State rebates can reduce costs further
