These are both true, furthermore a lot of the bigger players became big as a result of the initial round of solar rebate schemes - where a lot of low quality solar installations were put up. Now a lot of these companies are doing much larger jobs without the necessary skillsets. There's a bit of a minefield of shoddy installers still out there - look at the Crap Solar Facebook page for an insider look (there are some horrific installations).

Despite all this, I've seen a huge amount of interest in investors wanting large scale commercial and utility scale solar projects. From what I know, solar engineering consultancies are turning jobs away due to the demand being so great.
