This typically translates to about $2. 50 per watt of installed capacity (more on price per watt below). The total price depends on your system size, location, roof type, and installer. A panel's rated watts (also called its solar panel rating) help estimate how much power it can produce, how many panels you may need, and how your system might perform over time. Here's the tricky part: two systems with the same total kilowatts can generate very different amounts of energy. is between $15,000 and $25,000 before incentives. For example, the cost of a mounting structure is given in dollars per square meter of modules supported by that structure. High-efficiency modules have climbed to €0.
