Before we move on to our discussion of 15-kilowatt (kW) installations, let’s take a moment to discuss something that’s not as cool or exciting as solar, but can save you some serious cash in the long run. Installing solar is a great financial decision, but did you know that energy efficiency. .
Now on to solar installations. There are many ways to look at the size of a 15 kW solar installation: .
The average installation cost for residential solar, according to a 2016 report from the National Renewable Energy Lab, is $2.93 per watt. So if you purchased a 15 kW system in cash, you’d pay $43,950. Yes, quite a bit of money, but let’s see if we can bring that cost down. Standard residential solar panels measure 66 inches by 40 inches, or a little over 5 feet long and 3 feet wide. Each panel therefore takes up around 18 square feet. Commercial panels tend to be a bit bigger than residential panels, averaging about 6.5 feet long. [pdf]
