The Net EPC is Calculated as follows:
Let’s presume the total system cost including the System cost and Sonnen Bonus is $X.
The additional total cost to the customer in terms of Adders and Batteries is $Y.
So Net EPC to sales = $X - $Y
or simply put
The Net EPC to sales = Total System Cost( System+ Sonnen Bonus) - Additional Cost(Adders+Battery)
