Cost per square foot varies by system size, energy use, location, and panel efficiency. The most accurate pricing metric is still cost per watt, but per-sq-ft estimates are
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. If you purchase through a full-service
The cost associated with a 140-watt solar panel typically ranges between $100 to $250. However, various factors such as quality, brand reputation, and market trends can
Solar panel installation costs vary by the installation company and project scope, making it challenging to pinpoint exactly how much you''ll pay to have a pro install your solar panels.
Let''s cut through the jargon first - when we talk about photovoltaic (PV) panels, we''re essentially discussing sunlight-to-electricity converters. A 140W panel in 2025 typically ranges between
HomeAdvisor''s Solar Panel Price Guide gives the average home solar system and panel prices. Explore solar panel pricing per watt or square foot.
Costs start at $2.50–$3.50 per watt nationally, per 2025 data from EnergySage. That''s $15,000–$28,000 for a mid-size setup before add-ons. But why the range? Your energy
One of the biggest cost factors for your solar panel installation is the size of the system you have installed. System size is measured in kilowatts (kW) and is determined by
Expect the cost per watt to be between $2 and $3. As of publishing, the average cost per watt is $2.84. Most solar companies set the price according to the solar system''s
Solar panels cost about $21,816 on average when purchased with cash or $26,004 when purchased with a loan for a 7.2 kW system. While that price tag seems steep, the electricity bill savings you get from solar
Solar panels cost about $21,816 on average when purchased with cash or $26,004 when purchased with a loan for a 7.2 kW system. While that price tag seems steep, the electricity bill
The cost associated with a 140-watt solar panel typically ranges between $100 to $250. However, various factors such as quality, brand reputation, and market trends can significantly influence this price.

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.
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.
You’ll pay $4,200 to $6,000 to set up a 6 kW system. Concentrated photovoltaic (CPV) panels are $0.80 to $1.10 per watt. While not as well-known as other types of panels, CPV panels are highly efficient and may grow in popularity. A 6 kW solar system would cost $4,800 to $6,600.
The most accurate pricing metric is still cost per watt, but per-sq-ft estimates are helpful for ballpark figures. In California, electricity rates are among the highest in the nation, making solar ROI faster than average — see average electric bill in California.
Divide annual kWh by ~1,200 (typical kWh/year per kW of solar in much of California). In California, expect $2.75 – $3.50 per watt before incentives (solar panel cost in California). This gives your solar cost per square foot. Estimate your system size, price before and after incentives, and cost per square foot.
Since 2010, the cost to install solar panels on a home has fallen by roughly 50%. Costs rose slightly from 2020-2023 largely due to supply chain tangles from the pandemic, and then fell again in 2024. Prices have ticked upward slightly in 2025 due to tariffs and a rush for solar before the 30% consumer solar tax credit expires on December 31, 2025.
