How do you calculate $/W for a solar panel system? To calculate $/W, take the total out-of-pocket cost of the system 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.
