> Sometimes I think that half of HackerNews didn't even know solar or battery backups were a thing before Tesla. These are competitive spaces where Tesla has essentially no market share (just like cars).

I'm genuinely curious if the numbers reported by SolarCity represent the full picture. [1] shows SolarCity with ~35% national marketshare while the closest competitor is at just over 10% (Vivint). This was in 2015, but it still appears to have a significant lead.
