How do I know if the panel I am being quoted on is Tier 1?

Ask me. My contact details are here. Email is best!

Why don't you publish a comprehensive list online so I don't have to bug you?

Tier rankings are published by a very small number of independent solar industry analysts and, due to the effort and importance of the information, rankings are generally not openly published but rather are sold as industry intelligence

My list cost $4,000, and if I put it online the author will kill me! Just shoot me an email. I will reply.

If you do find a list online it is is probably both out of date and based simply on the opinions of the author. It is highly unlikely to be a based on a rigorous ranking methodology from an independent solar research house.
