The third quarter of 2013 was huge for the solar industry, the second strongest ever in the U.S. for solar installations, and the first strongest in terms of residential installations. Fool energy analyst Taylor Muckerman is keeping a close eye on how the fourth quarter looks for SolarCity (NASDAQ:SCTY) when it announces earnings this afternoon.

Meanwhile, Fool analyst Jason Moser will be watching the Chinese web portal Sina (NASDAQ:SINA), which owns the popular Chinese microblogging site Weibo, a site many have called the Chinese version of Twitter. Jason discusses rumors that Sina may spin off the Weibo business, which would then have its own IPO. He says he'll be watching when the company reports earnings after market close today to see if the company gives any further news on that front.
