SunPower’s overall cost performance

SunPower reported a lower cost of revenue across all operating segments for 3Q17.

The fall was partially offset by a rise in the cost of revenue, from $7.7 million in charges recorded in connection with the contracted sale of raw material inventory to third parties, $12.4 million charges for raw material sold to suppliers, and write-downs totaling $2.3 million on some solar power development projects in 3Q17.
