6 FAQs about [How much does a solar panel cost in watts ]
How much does a solar panel cost?
Today’s premium monocrystalline solar panels typically cost between 30 and 50 cents per Watt, putting the price of a single 400-watt solar panel between $120 to $200 depending on how you buy it. Less efficient polycrystalline panels are typically cheaper at $0.25 per Watt. The cost of a solar panel also depends on how you buy it.
What is the average cost per watt for solar panels?
First, PPW allows you to get a ballpark estimate of how much solar would cost for your home. Use this article to see how many solar panels you’d need, and then multiply the size of the system by the SEIA’s average PPW of $3.27 to get an estimated cost for the system.
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 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.
How to calculate solar cost per watt?
To calculate solar price per watt (PPW), 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.
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.
