In 2026, solar energy continues to attract homeowners and businesses seeking lower electricity bills and greater energy independence. However, the landscape has shifted. With the U.S. federal residential Investment Tax Credit (ITC under Section 25D) expiring at the end of 2025, many wonder if the numbers still add up.
At Watts & Ergon, , we believe in transparent advice. Solar remains a strong investment for most suitable homes, but success depends on your location, electricity rates, system design, and realistic expectations. Here’s the unvarnished truth.
Average residential solar system costs (before any remaining incentives) range from about $2.50–$3.60 per watt installed. A typical 6–8 kW home system might cost $18,000–$28,000+ before incentives, varying by equipment quality, roof complexity, and location.
Module prices face some upward pressure in 2026 due to trade policies, supply chain adjustments, and material costs (like silver), but overall installed costs have stabilized or declined over the long term thanks to technology improvements.
Without the 30% federal tax credit for direct purchases, payback typically ranges from 7–12 years, depending heavily on local utility rates and net metering policies.
In high-rate areas with good sunlight: 6–9 years
After payback, you enjoy 15+ years of near-free electricity (panels warrantied for 25+ years).
Many homeowners save $1,000–$2,000+ annually, potentially $30,000–$60,000+ over 25 years, assuming rising utility rates (often 3–6% annually).
| System Size | Gross Cost (Pre-Incentives) | Net Cost (No Federal ITC) | Annual Savings (Est.) | Payback Period | 25-Year Savings (Est.) |
|---|---|---|---|---|---|
| 6 kW | $15,000 – $22,000 | $15,000 – $22,000 | $900 – $1,500 | 8 – 12 years | $25,000 – $45,000 |
| 8 kW | $20,000 – $29,000 | $20,000 – $29,000 | $1,200 – $2,000 | 7 – 11 years | $35,000 – $60,000 |
| 10 kW | $25,000 – $36,000 | $25,000 – $36,000 | $1,500 – $2,500 | 7 – 10 years | $45,000 – $75,000 |
*Notes: Figures are approximate and vary significantly by location. Add battery storage for energy independence. State/local incentives can shorten payback further.
The biggest truth: Solar is not a get-rich-quick scheme. It’s a long-term infrastructure upgrade.
We focus on customized designs, quality components, and transparent projections. Get multiple detailed proposals with production estimates (use PVWatts or similar tools) and 25-year cash flow projections.
In sunny areas with above-average electricity rates who plan to stay long-term.
If your rates are very low, roof needs replacement soon, or you’ll move within 5 years.
