Tier 1 solar panel is a set of financial-based criteria defined by BloombergNEF to find the most bankable solar brands suitable for utility-scale applications. Tier 1 module manufacturers must have supplied their own brand products manufactured in their own facilities to at least six different projects larger than 1.5 MW, which were financed by six different banks in the past two years. A smart solar investor might recognise that BloombergNEF’s tiering system values solar module brands who specialise in large, utility projects.
