Many blogs and websites propose solar PV panel manufacturers with a Tier 1 label to homeowners for mounting rooftop systems. In other words, they induce it as a criterion for homeowners to choose among different brands. But what is really tier 1 and why should you know about it.
According to Solarity, the exact definition of Tier 1 label is the following:
“Tier 1 module manufacturers are those which have provided own-brand, own-manufacture products to six different projects, which have been financed non-recourse by six different (non-development) banks, in the past two years.”
These projects must be:
- Larger than 1.5 MW
- Location, capacity, developer, bank, module maker must be in the public domain
- Any brand with financial issues such as bankruptcy, insolvency protection or major default on bond payment will be removed from the Tier 1.
Tier 1 is the sign of financial stability or bankability of a solar panel manufacturer but is NOT the sign of quality.
Therefore, it is not a suitable idea to make your decision to tile your rooftop only based on finding these Tier 1 solar panels.
