The largest US solar installer SolarCity recently lowered its megawatt (MW) installation guidance that depicts a rollercoaster ride through the year.

The company recently revised installations to a range of 900MW to 1,000MW for the full-year, compared to 1,000MW to 1,100MW, previously. 

However the quarterly deployments are anything but lumpy. SolarCity previously reported first quarter installs of 184MW, up 32% from the prior year period but down from 221MW in the fourth quarter of 2015.

In releasing second quarter results, installations picked-up to 201MW, but guided third quarter installs at around 170MW. As the company noted, to meet lowered guidance, fourth quarter installs would have to be in the range of 315MW to 415MW, both figures being much higher than the company had ever achieved to date.
