Solar costs look different in 2026 than a few years ago — the federal tax credit that used to knock 30% off the price is gone, and equipment costs have shifted. Here's what solar actually costs right now.
| System Size | Typical Home | 2026 Cost Range |
|---|---|---|
| 4 kW | Small home | $10,000–$13,600 |
| 6 kW | Average home | $15,000–$20,400 |
| 8 kW | Larger home | $20,000–$27,200 |
| 10 kW | Large home / EV | $25,000–$34,000 |
| 12 kW | Very large + storage | $30,000–$40,800 |
Panel quality: Standard panels run $2.50/watt; premium high-efficiency panels run up to $3.40/watt.
System size: Determined by your electricity usage.
Roof complexity: Steep pitches or difficult access add labor cost.
Region: California, New York, and Massachusetts run 20-30% higher than average.
Battery storage: Adds $9,000-$18,000 per battery unit.
The 30% federal residential solar tax credit expired December 31, 2025. Homeowners in 2026 pay full price without that credit. Some states still offer their own incentives.
For most homeowners, yes. Electricity rates have risen substantially and equipment costs have dropped over the past decade. Payback periods run 7-12 years typically, 5-7 years in high-rate states.
