Yes, but you are missing out on the whole economics of solar power. Anyway, I think I've done enough to try to explain why your base assumption that 'quality correlates with price of the goods are limited in quantity' doesn't always hold. What is happening here: there is a backlog for those that are willing to work for a rate that makes the economics of solar work (both for them as subcontractors/employees, their employers
and the customers) and outside of that envelope (which is a filter I really should have mentioned) people may be available but unable to get jobs.
If you're arguing that solar power installations are too cheap then you may well have a point but that isn't going to convince a lot of people to change to the point where it is no longer viable. If anything the market is getting more and more competitive as more people enter it. In 2005 I paid about $30,000 for a solar power system that produced 3200 Watt on a good day in March, today I paid about $12000 for a system that produces well over 10KW. Installation costs as a fraction of the total bill has gone up, not down during that time, but in an absolute sense they've gone down because installations are now much simpler and far more routine. Back then every installation was an experiment, now it is routine.
It always seems nice to be able to simplify things to the point where they become soundbites but reality is rarely that simple.
Anyway, I repeat: the accent was on dependable. That does not necessarily correlate with price (though it would nice if it did...).
