Did you know that some foreign manufacturers try to confuse people with their Tier 1 branding by claiming their products have high quality?
Bloomberg NE Financial is a respectable research organization that helps energy professionals generate opportunities in new energies. As their name mentions, it focuses on the financial, which overshadows the certification of the quality of the solar models.
BNEF Issued a list of manufacturers that have financed at least six projects of 1.5 mW up. This list, The Tier 1, is not a list based on the quality nor on the economic solvency of the manufacturers. Even BNEF’s recommended buyers and banks purchasers do not use this list as a measure of quality.
If you really want to buy quality products that offer the power they promise they will provide, then buy Solar Modules with IEC and UL certifications. In fact, a vast majority of foreign manufacturers mainly Asian do not have it.
