Tier 1 Solar Panels  

If you want to buy 50,000 solar panels for your 15 MegaWatt commercial solar farm you probably want to make sure that the brand you are buying is likely to be around for the next 30 years to warranty them all. Same applies to the 20 or so panels on your home.

As a result, an International big business finance company came up with a Tier system. (Bloomberg New Energy Finance or BNEF)

Tier 1 means that the manufacturer is very large, with plenty of experience in large scale projects and currently financially healthy. There are about 30 of these companies listed below. Tier 2 meant the company wasn't quite large enough to make it to Tier 1, and Tier 3 and Tier 4 were for increasingly smaller companies.

A Tier 2 panel isn't likely to be inferior to a Tier 1 panel in quality, performance, reliability, it simply means the company making it hasn't reached the enormous manufacturing capacity of the Tier 1 giants. Some of the Tier 2 companies are just as automated as the Tier 1 brands and have been around a lot longer and are more profitable but Tier 1 rewards SIZE more than anything else.
