That's laughable. The interview process speaks for itself. People are hardly "Flocking" to them. Their terms of employment are not nearly as good as before. Personally, I do not have any interest in Solar sales. But, when one deals with sales people on a daily basis and advises them on career choice/paths, one gets a lot of info on many companies.
I'm not nearly as enthused about solar as many are. It is, largely, an artificially contrived market that would not exist without gov't subsidies or programs like net metering. There is an abundance of inexpensive energy available; energy that is must less expensive than the true cost of solar. But, the gov't, especially the snowflake gov't out in California, requires providers to buy more expensive forms of green energy, thus raising everyone's rates and making solar borderline attractive.
A relative of mine recently considered going solar. They talked to three companies. I was there for two of the presentations. The bottom line was this, on a power PPA he would save, in the near term, $25.00 (+/-)/ mo. However, the annual increase in payments + the degradation factor charges seriously diminish those monthly savings over time because, taken together, those factors are higher than the avg annual rate (15 yr avg) of increase of the utility company.
Of the companies involved, Solar City was the worst, with SunRun being right in the middle of the three. Solar and Sun really pushed the PPA ( those are more profitable to the company in the long term), but neither could compete well on a sale of the system.
