How much does a solar system cost per watt?
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. Expect the cost per watt to be between $2 to $3. As of publishing, the average cost per watt is $2.84. Solar panels typically pay for themselves within 5 to 15 years.
How much do solar panels cost?
If you just need a few panels for a small do-it-yourself solar project, expect to pay around $200 to $350 per panel (between $0.80 and $1.40 per watt). Note: The table below doesn’t include the cost of a solar storage battery, which can add anywhere from $7,000 to $18,000 to your total system costs. Average solar panel system cost by system size
How much does a home solar system cost?
According to the SEIA, home solar systems have an average price of $3.24 per watt in the U.S. before incentives. Comparatively, our team found an average cost per watt of $3.10 based on our survey responses. Note that system pricing can vary based on the solar panel and equipment brand, installer, location and more.
What is the average price per watt for residential solar projects?
According to the Solar Energy Industries Association, the average price per watt for residential solar projects was $3.27 in the first half of 2023. For example, the PPW of a 5,500 Watt system looks quite different before and after accounting for the 30% tax credit.
How do you calculate wattage of a solar system?
To calculate the wattage of a solar system, you divide the cost of the system (in dollars) by the size of the system (in watts). PPW = System cost / System wattage. Since solar systems are typically sized in kilowatts (kW), you'll have to multiply by 1,000 to convert to watts. For example, a 5.5 kW solar system is equivalent to a 5,500 Watt solar system.
Why are larger solar systems cheaper per watt?
In general, larger solar systems have a lower price per watt. This is because soft costs (permitting, installation, inspection, customer acquisition, and overhead) are roughly the same from project to project and don't add capacity to the system. Here are some other factors that influence the price per watt of a solar system.
