How are the Final and Net System Costs Calculated?

Final System Cost

The Final System Cost is the total cost of the system, including base ppw, adders, and dealer fees. Unless the customer is paying cash or has a down payment, this will be the same as the "Financed Amount". 

This number is found using this equation: 

Final Price per Watt x (System Size x 1000) = Final System Cost

Because all of the numbers on our proposals are rounded up, the number you get won't be the exact same as the one on the pricing tab, but it should be close. For example, the proposal pictured below would calculate as this:

5.85 x (8.14 x 1000) ≈ $47,619

 And our system calculated it as $47,641.03:

Net System Cost

The Net System Cost is just the final system cost, with the incentives and down payments subtracted. It is displayed on the Finance page, under the loan amount and any applied incentives. 

For example, in the proposal pictured below, the final system cost is $21,627.08, the customer's ITC comes out to be $6,488.13, and there is a down payment of $2,000, which plugged into the equation is this:  

Our system calculates it at $12,587. Remember, our system doesn't round the numbers until the final result.
