Most companies selling SolarPV use subbies, so you can get good or bad results from the same supplier unrelated to the panel quality.
Not sure about the panels at the moment, supply is an issue and it seems quality is highly variable. Most of the panels come through just 2 or 3 wholesalers, nearly all of them out of China, even the ones that claim they aren't Chinese usually means they aren't Chinese owned but the panels are still usually Made in China.
Part of the trick therefore is to find a good installer, it makes the difference.
