TIER-1 Solar Panel Reality
THERE IS NO SUCH THING AS A TIER-1 SOLAR PANEL. It’s the first point which must be established. This is the most misused term in the solar industry. If you like the sound of the term Tier-1, glossy datasheets promising the world with unproven warranties and stories of fluff, stop reading. Before seeing the images of critical failure in cheap, so-called “Tier-1 solar panels” understand this, Tier-1 solar panels do not exist. Ask anyone with respectable knowledge in the industry and they will tell you the same. In a bid to keep it simple, see below.
Tier-1 in a nutshell.
- Only Tier-1 solar panel manufacturers exist.
- Tier-1 is a term created by Bloomberg with no criteria of quality in the selection process.
- Bloomberg does not audit manufacturing facilities or product. It’s purely financial. Therefore, the Tier-1 list of solar panel manufacturers changes quarterly.
- Tier-1 is a label which will not stay with the product for life as it is not a quality guideline and Bloomberg is not a testing institute.
- Random audits on dubbed Tier-1 solar panel brands found cases of inadequate production against the nameplate value when subjected to Standard Test Conditions straight out of the box.
- Tier-1 solar manufacturers rated by volume have greater product defects.
Proof that Tier-1 is no gauge for quality. The fact is, Tier-1 is a term low-end market sellers exploit to give the buyer a feeling of confidence in a cheap product. In most instances, beneath the surface is an underperforming electrical mess, despite the bank ability of a certain manufacturer in a nominated quarter. Industry experts suggest “be the savvy shopper” and always seek BEYOND TIER-1.
