View DetailsSolar panels cost between $0.30 and $0.90 per watt without labor and other fees. Since your typical solar panel system size is 6.5 kW, anticipate spending around $3,900 for the panels alone, or somewhere between $1,950 and $5,900. However, system sizes range from 3 kW to 11 kW, so you could see prices for as little as $900 or as much as $8,800.
Another measure of the relative cost of solar energy is its price per kilowatt-hour (kWh). Whereas the price per watt considers the solar system's size, the price per kWh shows the price of the solar system per unit of energy it produces over a given period of time. Net cost of the system / lifetime output = cost per kilowatt hour
These benchmarks help measure progress toward goals for reducing solar electricity costs and guide SETO research and development programs. Read more to find out how these cost benchmarks are modeled and download the data and cost modeling program below.
Installation labor accounts for only 5.5-7% of total cost ($1,375-$2,500 for average systems), while soft costs represent 40-50% of total investment: Solar costs vary significantly by location due to labor rates, permitting requirements, market competition, and local incentives.
