Solar 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.How much do solar panels cost?The price of solar panels changes depending on where you live, but the average for installation is just under $29,000 or $2.75 per watt. On the high end, we talked to a solar customer in Hawaii who spent $100,000 going solar. Dion in Nevada said their 10-kW system cost about $20,000, which is about the national average price for a 7-kW system.
How much does a home solar system cost?According to studies by the U.S. Department of Energy, the all-in cost of a home solar panel system is between $2.74 to $3.30 per watt. 1,2,12 This figure includes the solar panels, the installation, and other expenses. Using these numbers, an average-sized 8-kilowatt residential solar system would cost between $21,900 – $26,400.
How much does a commercial solar system cost?Commercial solar installations are a great way for companies to lower energy costs. Generally, installing solar panels on businesses costs a bit less per watt because the systems are larger, but the total costs will be higher. In 2025, the average cost for commercial solar panels is just about $2.00 per watt.
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 do you calculate the cost of a solar system?Solar panel costs are usually measured in the cost per watt of solar installed. However, solar system sizes are measured in kilowatts (kW). To calculate the total price of installing a home solar system, you’ll need the system size to be in watts. To convert kilowatts to watts, all you need to do is multiply the system size in kW by 1,000.
