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. 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.
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.
Monocrystalline solar panels are the most popular choice for residential installation (nearly all residential solar panels installed in 2022 were monocrystalline) because they have the highest efficiency rates from 17% to 22%. The average cost for these panels is between $1 and $1.50 per watt, but prices may differ depending on location.
Mounting system: This is what holds rooftop solar panels in place. Costs vary depending on the type of solar installation, but it generally costs between 7 and 20 cents per watt. Electrical wiring and hardware: This includes the wiring, switches and circuit breakers required to connect the solar panel system to your home's electrical system.
