From 2010 to 2020, solar panel prices dropped by nearly 90%, with costs per watt falling from approximately $3.86 to $0.38 globally (source: IRENA). This decline slowed in recent years but remained consistent. Between 2020 and 2025, residential solar system costs, averaging $2.50 to $3.50 per watt in 2025, decreased from $3 to $4 per watt in 2020.
In 2025, the average cost for commercial solar panels is just about $2.00 per watt. There is a lot to consider when figuring out how much you’ll spend on a solar installation. Here are five steps to help you calculate how much a system will cost to install for your home:
Although home solar is already more affordable than paying for utility electricity, there are a few ways to reduce the cost of your system and maximize your energy cost savings. First, there are solar incentives offered by federal, state, and local governments, in addition to utility providers.
For reference, the national average cost of solar panels is $3.03 per watt. Solar rebates help make solar more affordable by directly lowering the upfront cost of a solar installation. If you have access to solar rebates, consider yourself lucky! They are few and far between these days.
