Solar Panel Cost in 2026: Complete Price Guide
Last updated: February 1, 2026
Average solar panel costs in 2026 by system size, brand, and state. Breakdown of equipment, installation, and total system pricing.
Solar costs have dropped 90%+ since 2010, but the pricing still isn't transparent. Every installer quotes differently, making it hard to compare apples to apples. Whether you're getting your first quote or your fifth, understanding the cost breakdown helps you spot good deals — and avoid overpaying.
In 2026, the average residential solar system costs $2.50–$3.50 per watt installed, or $15,000–$25,000 for a typical 6-8 kW system before the 30% federal tax credit. Panel hardware accounts for 25-35% of total cost, with installation labor, inverter, racking, permitting, and overhead making up the rest. Our database covers 107 panel models across 32 brands, ranging from budget PERC models to premium HJT and IBC options.
Key Takeaways
- • Average installed cost: $2.50–$3.50 per watt (total system)
- • Panel hardware: $0.25-$1.00 per watt (25-35% of total)
- • Inverter: $0.30-$0.60 per watt
- • Installation labor: $0.50-$1.00 per watt
- • After 30% tax credit: $1.75–$2.45 per watt net cost
- • 6 kW system: ~$15,000-$21,000 before credit; 10 kW: ~$25,000-$35,000

Frequently Asked Questions
Why do solar prices vary so much?
Price differences come from: panel brand/tier (budget vs premium), inverter type (string vs micro), roof complexity (multi-story, steep pitch, tile), local labor costs, permitting fees, and company overhead. Getting 3-5 quotes from different installers is the best way to ensure competitive pricing.
Are solar panels getting cheaper?
Solar panel hardware costs have dropped 90%+ since 2010, but the decline has slowed recently. The main cost driver now is installation labor and soft costs (permitting, sales, overhead), which are harder to reduce. Expect modest annual cost declines of 2-5%.
What is the cost breakdown of a solar system?
For a typical residential system: panels (25-35%), inverter (10-15%), racking/mounting (5-10%), installation labor (15-25%), permitting and interconnection (5-10%), and company overhead/profit (15-25%). The exact split varies by system size and local market.
