Shopping for a solar panel by manufacturer alone is quite like shopping for a car by the manufacturer alone. The differences are often enormous between models. Nonetheless, questionable marketing tactics towards end-users would have you believe the term Tier-1 is all you need to know.

Each year Solar Review publishes the Latest Tier-1 Solar Panels List in a bid to assist end-user education understand the term Tier-1 was not created as a quality guideline.  

Comprised of “existing sources” already made publicly available on the internet, this Latest Tier-1 Solar Panels List 2021 is available in an easily indexable fashion for your browsing convenience. Not to be confused, the Bloomberg Module Tiering List 2021 is not published by Bloomberg New Energy Finance online.  

IMPORTANT. If considering the BNEF PV module tiering system report, Bloomberg New Energy Finance state;

We strongly recommend that module purchasers and banks do not use this list as a measure of quality, but instead consult a technical due diligence firm such as RINA (formerly OST Energy), ATA Renewables, Wood Plc, PVEL, Black & Veatch, TUV, E3, STS Certified, Clean Energy Associates, PI Berlin, Pvbuyer, Enertis, Oravia, Leidos Engineering, the Austrian Institute of Technology (AIT) or Phoventus. These would usually consider what factory the module comes from, as well as the brand, and give an informed opinion on whether the modules will perform as expected.

A responsible addition to the documentation purchasers should adhere when making a buying decision.

Q1 2021, when compared to Q4 2020, we said goodbye to; GCL Systems, Neo Solar, Hengdian and Goldi Solar, for what particular reasons, we are unsure. Coming onto the Tier-1 Solar Panels List in Q1 2021 is; Kyocerra, BYD and AE Solar.

It’s confusing for many that some of the world’s most renowned solar panel manufacturers aren’t on the Latest Tier-1 Solar Panels List 2021. Notable absentees and manufacturer’s with an outstanding quality reputation missing from various quarters below.

Not to discredit tiering systems such as the Bloomberg Module Tiering List, as these have their place in the solar industry for few. Such place, however, is reserved for those seeking selected manufacturer financial qualifications for banks when investing in solar farms. Research criteria deemed a fraction of the overall project feasibility. 

Solar module manufacturers not listed simply may not specialise in solar farm type modules, which have no place on a residential property and, therefore, to be included on such list is irrelevant.

Fluctuating quarterly, the term Tier-1 is a manufacturer endorsement that does not stay with any particular product for life. Certifications and awards by trusted testing institutes do though. 

Fluctuations.

Tier-1 Alternatives.

Are solar modules many would even consider above Tier-1 standard. Notable manufacturers with an elite product quality rating not included in the Latest Tier-1 Solar Panels List 2021 (within a selected quarter). Many industry experts and due diligence firms would suggest being above alternative Tier-1 manufacturers in innovation and product quality.

  1. Why is GCL Systems not on the list anymore? How is it possible, that a company with 7 GW capacity in Q4/2020 is not on the list anymore in Q1/2021?
