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. In India, the DC solar pump price list starts from ₹30,000 to ₹1,00,000. This depends on the pump’s size and features. AC solar pumps need a solar inverter to convert power. This makes them a bit more costly. The AC solar deep well pump prices list varies between ₹50,000 to ₹2,00,000. [pdf]
