Solar module failure rates remain to climb as record variety of makers acknowledged in PVEL Module Reliability Scorecard

  • A total amount of 117 modules from 26 producers have actually received 'Top Performer' status within PV Evolution Labs' (PVEL) 2021 Module Reliability Scorecard, however the report has actually also highlighted a rise in failing rates within the sector.

The scorecard, released today, highlights findings from PVEL's PV Module Product Qualification Program (PQP), racking up solar modules complying with the outcomes of numerous screening procedures, consisting of thermal cycling, damp warm and LID/LeTID sensitivity. It is designed to give empirical information for module maker benchmarking, while additionally giving understanding for the upstream solar sector.

Now in its seventh year, the scorecard can similarly act as measure for tracking solar module failing prices, and this year's version highlights a sharp boost in the instances of certain failures observed by PVEL.

Probably most especially, one in three makers taking part in this year's PQP experienced security failures associating with junction box flaws, a boost from one in five which experienced such failures last year. Moreover, the majority of these failures were observed before screening, essentially straight from package.

There was likewise a rise in the failure price within the expenses of product (BOMs). Around 26% of the BOMs eligible for this year's scorecard had at the very least one failing, contrasted to 20% recognised in last year's edition.

The best number of failures took place during the mechanical anxiety sequence, added to PVEL's PQP for this year to resolve sturdiness issues associating with extreme weather condition.

There were, nevertheless, favorable takeaways from this year's scorecard. The highest number of makers have actually been noted within the scorecard's seven-year background, while there has been an ongoing enhancement in both module performance during thermal biking and PAN efficiency.

PVEL claimed concerns with reliability recognized by the PQP might jeopardize efficiency gains achieved with technological advancements. "The preventable safety failings observed in this year's Scorecard emphasize the complex tests that manufacturers encounter as they race to fulfill demand in a highly dynamic international market," Jenya Maydbray, Chief Executive Officer at PVEL, said.

Engagement in PVEL's PQP and scorecard is volunteer. To be eligible for addition, suppliers need to complete a factory witness examination within 18 months of 2021, submit BOMs to all examination series and have submitted at least two factory-witnessed PV module samples per examination series. Only modules that report destruction of less than 2% in each reliability test sequence are provided 'Top Performer' condition, as well as top performers should also finish in the top quartile for energy yield.

The total scorecard has been made available in both an on the internet digital style and also via downloadable PDF at www.modulescorecard.pvel.com.

In addition, PVEL is co-hosting a webinar alongside PV Tech to discuss the findings from this year's scorecard later on today. Registration is still open, as well as further information on exactly how to attend can be found below. A webinar of the recording will be provided at a later date.

Tara Doyle, chief business officer at PVEL, claimed the scorecard demonstrated that while the high quality of a PV module was dictated at the very least partly by the products it includes, several purchasers do not presently request BOM details.

" Between supply chain instability and the ever-present promote reduced prices, one can not think that every module offered under a provided version kind uses evaluated BOM components. Purchasers have to specify their preferred BOM in supply agreements to attain this," Doyle said.

' Tremendous accomplishment'

Trina Solar is one of simply two firms, the various other being fellow 'Solar Module Super League' member JinkoSolar, to have actually gotten Top Performer standing in all seven editions of PVEL's module scorecard, an accomplishment defined by PVEL head of PV module business Tristan Erion-Lorico as a "tremendous success".

Cao Bo, deputy basic supervisor at Trina Solar, added: "With greater than 20 years' buildup of technical know-how, Trina Solar is devoted to sustainability through the delivery of high power, extremely efficient and top-performing modules with tested high quality as well as reliability."

Of the manufacturers to have been acknowledged in the 2021 version of PVEL's scorecard, Indian solar producer Adani protected Top Performer condition for the fourth consecutive year having actually been acknowledged in each edition since 2018.

Ramesh Nair, chief executive officer at Adani Solar, claimed the scorecard was an "very useful" tool utilized throughout the sector to make sure jobs step forward with reputable and also long lasting products. "Four victories in a row for Adani Solar is a testament to our manufacturing excellence and also reflects on our dedication to produce Solar PV Cells & Modules while ensuring best quality, bankability & reliability," Nair said.

Boviet Solar Innovation, a US-headquartered solar manufacturer initially established in Vietnam, was identified for a 3rd successive year and the business highlighted its certain honor in the possibility caused degradation (PID) classification. "PID is becoming a major problem in the industry. Being named one of one of the most trustworthy suppliers in the PID category is a testimony to Boviet's high-quality style, premium components and precise manufacturing procedure," Sienna Sen, head of state at Boviet Solar U.S.A., said.
