## How do you determine the value of solar panels?

To calculate \$/W, take the total out-of-pocket cost of the system that you are considering and divide it by the number of watts of capacity in the system. For example, a 5kW solar system has 5000 watts. If that system costs \$15,000, then the cost per watt is (\$15,000 / 5000W =) \$3/W.

## How much money do you get back from solar panels?

The average cost of solar panel installation is \$17,000 in the U.S., though tax breaks and other discounts can make it as low as \$5000 in some states.

## How do you calculate solar net present value?

NPV is presented in dollars and is calculated by subtracting the cost of the initial investment from the sum of the total discounted future cash flows over the lifetime of the investment (i.e., the present dollar value of future cash flows, calculated using the discount rate).
