We usually measure or convert the watts into amps of solar panels to figure out how much current (amps) is being stored in the battery. Or we measure the amperage of the solar panel. To calculate the current when your solar panel is generating its maximum power, you need to divide the maximum rated power of the panel in watts by the maximum power voltage (Vmp) which is also in volts. You can find the wattage of your panel on the back of it, or in the installation manual. [pdf]

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. A small residential solar panel system costs around $14,210 before considering any financial incentives. On the bright side, that price effectively drops to $9,937 after considering the full federal solar tax credit. [pdf]
