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. .
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. .
Now on to solar installations. There are many ways to look at the size of a 15 kW solar installation: In terms of cost, the article mentions that the average installation cost for a 15kW system is around $2.93 per Watt, totaling approximately $43,950. However, with a 30% federal tax credit, the cost can be reduced to $26,370. [pdf]

The following table provides a lookup for the solar hours per day in the biggest cities in each state of the USA. Use the solar hours per day in the calculator above. If you know the annual kWh consumed at the property, then divide it by the kWh per 1kW to determine the solar array. .
Find your Solar Hours per Dayusing the color-coding on this map. Enter the value for your location into the solar calculator. The solar map uses. .
At SunWatts, we make solar simple, and calculating how much solar you need has never been easier. On our Calculate How Much Solar page,. To achieve a daily 100 kWh electricity output, you’d require 50 to 52 solar panels, each rated at 400 Watts. These panels capture the energy from the sun and transform it into electricity and they can generate sufficient energy to meet the target of 100 kWh. [pdf]
