Published May 16, 2026
With installation, an average residential 5kW size system costs between $3 and $5 per watt, according to the CSE, which results in the $15,000 to $25,000 range. That cost is before any tax credits and incentives. If you know your current energy usage, you can calculate how much you’ll need to pay for solar panels.
