@luvb2b i took a quick stab at trying to back into the numbers using the 2016 10-K, the 4Q2016 shareholder letter and the 2016 Q3 10-Q; i was a little surprised at the numbers i ended up with:
$47.3 million in energy storage revenue
$60.7 million in energy storage cost of revenue
$13.4 million gross loss
I am happy to email you the quick and dirty spreadsheet i used to populate the numbers on this if you would like to check my work -- i did this really quick and it could probably use another set of eyes. PM me if you'd like to see the spreadsheet.
Interestingly enough, the 4Q2016 shareholder does comment that gross margin was lower than planned due to scaling production capacity in Q4 for energy storage products to accommodate future growth.
Another comment -- for the nine months ended 9/30/16, energy storage revenue and cost of revenue was as follows:
$50.0 million in energy storage revenue
$50.5 million in energy storage cost of revenue
$0.5 million gross loss
Also, this spreadsheet has a solid listing of energy projects; could be helpful in trying to get at the revenue numbers
hope this helps,
