Bloomberg 3-tier rating system for PV module makers is based on bankabililty to differentiate the hundreds of solar module manufacturers. Simply put, the European Investment Bank (EIB) considers a project bankable if 3rd party lenders are willing to finance it1. BNEF ranks Tier 1 manufacturers as those that have provided own-brand, own-manufacture products to six different projects, which have been financed by six different (non-development) banks
in the past 2 years.
Manufacturers in China, India and Turkey are subject to a more stringent criterion that the project deal must be non-recourse, which means the bank undertakes the risk in the event of PV modules failing. LONGi Solar is ranked 7th, based on annual in-house production capacity.
While BNEF acknowledges that a Tier 1 ranking is not a recommendation, it is characteristic of transparency and good data availability. Moreover, BNEF Tier 1 ranking includes a notation which denotes module makers for which a technical due diligence is available from DNV GL. Less than 50% of the 34 the Tier 1 manufacturers have secured this independent validation. LONGi Solar’s modules have been validated by DNV GL.
In its fourth annual PV Module Reliability Scorecard Report 2018, released on 28th May 2018, DNV GL, the world’s largest independent energy experts and certification body, awarded LONGi Solar a “Top Performer” for module reliability. DNV GL awards are based on PV module reliability laboratory test, comprising: thermal cycling (TC600), damp heat (DH2000), dynamic mechanical load (DML) and potential induced degradation (PID). LONGi Solar was awarded “Top Performer” for its mono-crystalline PERC modules in all four tests categories. This is a validation of the advantages of high efficiency, high reliability and high yield of LONGi Solar’s mono-crystalline modules, and an endorsement of the advanced technology, equipment, product testing and R&D capabilities of the company.
LONGi Solar is established in 2000 in Xi’an, China and today it has operations worldwide. The company is fully integrated within the PV Solar value chain, from ingot casting to wafer, cells and module production to downstream energy services.
It is listed in the Shanghai Stock Exchange and its stock is a component of the Worldwide MCSI Stock index.
Over the last 3 years, LONGi Solar revenues has grown steadily, in a sustainable manner that ensures product quality and financial standing are not compromised. In 2017, LONGi Solar shipped 4.66GW mono-crystalline modules, ranking first in the world in mono-crystalline cell and module shipments for three consecutive years.
In the Altman-Z Score index, BNEF ranked LONGi Solar 2nd in financial strength amongst PV companies worldwide.
And as further evidence of its prudent financial management, LONGi Solar is ranked No. 1 with the lowest in debt ratio of 53% in the PV industry.
LONGi Solar has always placed the quality and advanced technology of its products and modules first. It has continuously increased R&D investment in advancing mono-crystalline technology. In 2017, the company invested RMB1.108 billion, 6.8% of its sales, in R&D, the highest among PV companies in the world.
With continuous R&D investment, LONGi Solar has made remarkable technological progress. Since September 2017, the company has broken the world records for PERC cell and module technology eight consecutive times. The technological breakthroughs will gradually be incorporated into series production of LONGi Solar products. The company has already started the transfer of their production lines to 100% PERC production in 2018.
