The leading US installer of rooftop solar now expects to put up 878-898MW in 2015, down from its previous guidance of 920-1,000MW.

More importantly, chief executive Lyndon Rive unveiled a “change in focus” for SolarCity that will see it de-emphasize the fiery installation growth it has become known for.

Instead, the “primary focus” will be the reduction of customer acquisition costs and becoming cash flow positive by the end of 2016.
