Solar system cost is fairly consistent across markets, and consistently getting lower with time. That said, there are a number of variables that drive the cost of a commercial or residential rooftop solar system:
- What is your roof made of?
- Is your roof easy to get to?
- Does your roof have a lot of space?
- Do you want basic panels, high-efficiency panels, or something in between?
If you need to generate a lot of power but have limited space on your roof, you may need to pay a premium for a more efficient panel. Higher quality panels capture more energy from the same amount of sunlight.
The solar systems we install typically cost between $2.80 and $3.80 per Watt. Considering most residential systems run between 4 and 15 kW (a kilowatt is 1000 Watts), we’re looking at about $11,000 on the low end, and $60,000 on the high end. That’s a big range, we know, but to be a little more specific, the large majority of home systems run between $20,000 and $30,000 (it’s important when assessing the price of your system to account for any solar rebates, which can save you a ton of money).
