How much does a solar system cost per watt?

As of publishing, the average cost per watt is $2.84. Most solar companies set the price according to the solar system's wattage. A solar installation's “cost per watt” is a little like the “price per square foot” when you buy a house. It helps compare the value of solar energy systems in different sizes.

How much does a solar system cost in 2025?

Solar panels generate “free” electricity, but installing a system still costs money. A typical American household needs a 10-kilowatt (kW) system to adequately power their home, which costs $28,241 in 2025. That price effectively drops to $19,873 after considering the full federal solar tax credit.

How much does a home energy system cost?

The average cost ranges from $15,000 to $35,000 for a complete system before incentives, or $2.50 to $3.50 per watt installed. After applying the 30% federal tax credit, net costs typically range from $10,500 to $24,500. Most homes need 7-12 kW systems to offset their electricity usage.

How much do solar panels cost?

Solar panels themselves represent only 12-18% of total system cost, typically $0.30-$0.50 per watt. Premium monocrystalline panels offer 20-22% efficiency but cost more than standard panels with 18-20% efficiency. Panel type significantly impacts both cost and performance:
