Data is knowledge:
Panelists on day 1 of the TaiyangNews Reliable PV Module Design 2024 Conference hailed testing and resultant data as the key to building module reliability. However, the industry cannot completely rely on this as cell technologies change rapidly with various manufacturers optimizing these on their own thus bringing in various variables.
Bifacial or monofacial?
Even as the world doubles down on bifacial solar modules, Silvana Ovaitt from NREL presented field test results to show that bifacial degrades generally faster than monofacial modules, thus impacting overall project economics.
UVID impact research ongoing
Sharing some UVID testing results, Kiwa PVEL’s Tristan Erion Lorico revealed susceptibilities in HJT and unexpectedly higher degradation in PERC. He added that the mechanisms behind UVID-induced degradation are not yet fully understood, and research is ongoing to address these issues.
Backsheet solutions important
Endurans’ Imco Goudswaard said that the severe price pressure and increasing requirements on modules and components are leading to the protection of PET core layer being compromised, thus impacting module reliability. He claimed 3% more power yield with the use of its HP transparent backsheet solution for bifacial modules.
Cell quality for module reliability
MoNo 2 cell of JTPV deposits a passivation film on half-cut cell edges to recover from laser damage and provide passivation. Dr. Xinrui An said an increase of up to 6W is possible with HEP for standard 182-72 modules with MoNo2.
Astronergy bats for ALD
Sibin Yang of Astronergy at @TaiyangNews Reliable PV Module conference listed the benefits of Atomic Layer Deposition technology to improve module reliability. While plate ALD provides uniform coating and is especially suited for large-scale production even though costly, tube ALD is better suited for small-scale production.
Reliability is the key
JA Solar’s Ignacio Espinosa said his company prioritizes reliability even in the face of cost pressures, with 100% in-house inspections to meet high standards.
While manufacturers are under dramatic cost pressure, JA Solar said it is not compromising on quality as it considers Reliablity to be key. It rather looks on improving the bill of materials by strengthening materials and with lower cost solutions (e.g. 0BB, new frames).
Keynote : Testing Quality and Reliability Procedures for Solar Modules
kiwa PI Berlin’s head Steven Xuereb shows in TaiyangNews Solar Module Reliablity event that only 10% (!) of modules tested in 2022-23 passed pre-shipment checks without finding any defects.
High-cost pressure vs. reliability?
Shravan Chunduri opens TaiyangNews Reliable Solar PV Module Design 2024 Conference. Introducing the topic of discussion today, he wonders if the impacts of the huge cost pressure that companies face today, can these have a direct impact on the reliability of modules? Food for thought, isn’t it? Let’s find out.
Panel discussion on day 1
Moderated by TaiyangNews’ Shravan Chunduri, the panel discussion on day 1, TaiyangNews Reliable Solar PV Module Design 2024 Conference has Ignacio Espinosa of JA Solar, Imco Goudswaard of Endurans, Steven Xuereb of Kiwa PI Berlin, and Tristan Erion-Lorico of Kiwa PVEL. They will share perspectives on if the solar module testing framework as it exists today is good enough to guarantee long-term reliability of solar modules? You wouldn’t want to miss this! Register
Knock, knock! Who’s there?
The 2-day TaiyangNews Reliable Solar PV Module Design 2024 Conference is bringing together speakers from various walks of the solar PV industry, including manufacturing, materials innovation, and of course testing fields. Today’s participants include Kiwa PI Berlin, JA Solar, Astronergy, JTPV, Endurance Solar, Kiwa PVEL, and NREL.
Let’s discuss solar module reliability!
Reliability has never been higher on the agenda for the global solar PV industry as it is now especially as prices hit a historical low. While solar module reliability is a critical tool that ensures its long and healthy life, it may not attract full attention as newer technologies constantly make news while profitability take centerstage as industry players face challenges ranging from stiff competition to trade issues. TaiyangNews Reliable Solar PV Module Design 2024 Conference, set to start at 12.00 PM CEST TODAY, attempts to explore the subject in depth. Register for the conference now, for free, here.
