How much does a PV system cost?
Our operations and maintenance (O&M) analysis breaks costs into various categories and provides total annualized O&M costs. The MSP results for PV systems (in units of 2022 real USD/kWdc/yr) are $28.78 (residential), $39.83 (community solar), and $16.12 (utility-scale).
What makes a PV system a market price?
Market prices can include items such as smaller-market-share PV systems (e.g., those with premium efficiency panels), atypical system configurations due to site irregularities (e.g., additional land grading) or customer preferences (e.g., pest traps), and specific project requirements (e.g., unionized labor).
How efficient is a rooftop PV system?
We model a baseline 8-kWdc rooftop PV system using 20.8%-efficient, 1.97-m2 monofacial monocrystalline silicon modules from a Tier 1 U.S. supplier, microinverters with an inverter loading ratio (ILR) of 1.21 imported from China with the Section 301 tariff, and a 5-kW/12.5-kWh alternating-current (ac) coupled lithium-ion storage system.
What is the IRA & how does it affect PV installations?
The IRA, which was passed into law in August 2022, created incentives for domestic PV manufacturing and deployment that analysts expect to drive significant increases in U.S. PV installations and use of domestically manufactured components (Feldman et al. 2022).

Solar Photovoltaic Panel Price Trends
Solar panel costs in 2025 depend on system size, installation, and region. The average cost per watt ranges from $2.50 to $3.50, translating to $12,500 to $17,500 for a 5-kilowatt system. Larger systems have higher upfront costs, but they reduce price per watt due to economies of scale. [pdf]FAQS about Solar Photovoltaic Panel Price Trends
How much do solar panels cost?
However, according to the Solar Energy Industries Association (SEIA), by 2010, substantial progress had been made in reducing costs. The price of residential solar panels dropped to nearly $7 per watt, commercial panels to $6 per watt, and utility-scale panels to $4.50 per watt.
Why do solar panels cost so much?
In the realm of solar panel costs, regional variations play a significant role, with prices influenced by factors such as local incentives, installation demand, and the overall solar market landscape. Examining the data on average solar panel costs per watt across different states provides insights into these geographical disparities.
How has the solar panel market changed over the years?
The solar panel market has undergone significant changes over the years, particularly in terms of pricing. To understand the trend, let’s delve into the historical and recent data available. In 1977, the price of solar panels was a staggering $76.67 per watt.
How much does a solar panel cost in 2025?
1. The average cost per watt for solar panels in the United States in 2025 is $2.94. 2. Installation costs depend on both the cost per watt and the wattage of the solar panel, influencing the upfront investment. 3. Solar panel costs have dropped from $7 per watt in 2010 to nearly $3 per watt in 2025, showcasing increased affordability. 4.
How much does a polycrystalline solar panel cost?
Polycrystalline solar panels provide a cost-effective alternative, with prices typically falling between $0.9 to $1.00 per watt. Similar to monocrystalline panels, they offer an average lifespan of 25 to 30 years.
How much does solar cost per watt?
We often reference the cost-per-watt ($/W) of solar to compare the value of a quote against the national average. According to the most recent data from the EnergySage Marketplace, the average cost-per-watt across the U.S. is around $2.53/W before incentives.
