Which brand of solar panels used by professionals and where to get them?

I think most pros install Fafco or Helicoil. You can get them from....pro system installers. I don't believe either is available directly to consumers.

Fafco is available on the web as a Google search will tell you. You can also find local dealers on their site. Helicoil is not a manufacturer of solar panels. Perhaps you were thinking of the Helio-Matic controller like I have on my system.

My system came with the house so I don't know what brand it is but it looks like a simple do-it-yourself project. We'll see when replacement time comes
