HT-SAAE awarded as a “Top Performer” in PVEL 2020 PV Reliability Scorecard
On May 28th, HT-SAAE was awarded as a Top Performer in PVEL 2020 PV Reliability Scorecard.With its splendid reliability and performance, HT-SAAE achieved a great success in many different criterias .HT-SAAE proved once again how ahead it was from its many competitors and ranked sixth globally.
The ‘2020 PV Module Reliability Scorecard’ report, undertaken each year by PV Evolution Labs (PVEL) in partnership with DNV GL continue to evaluate key aspects of module reliability. HT-SAAE was at the top of the list with its among 22 competitors and ranked 6th in the world as a leader manufacturer.
The table also ranks manufacturers by the total number of Top Performer awards, HT-SAAE was at top of the list with total 8 top performer modules which have been produced in Istanbul,Turkey Factory.
Pan Files is new line in the Top Performer Ranking test.HT-SAAE was ranked in the 2020 Pan Top Performers and the data presented is only from PVEL’s PAN testing as part of a PQP where the samples are factory witnessed.
There are a lot of moving parts in this testing, not least in relation to bifacial modules. Other differentiated yield performances simulated included a heterojunction module, which obviously offered high temperature performance gains, due to having some of the lowest temperature coefficients.
HT-SAAE has been also ranked among 2020 PID Top Performers. PID (Phenomenon of potential-induced degredation) has emerged over past 10 years with the development of higher system voltage and ungrounded systems.PVEL’s PID test is carried out in an environmental chamber with voltage bias equal to the maximum system voltage (MSV) rating of the module (-1000 V or -1500V) being applied under 85°C and 85% relative humidity for two cycles of 96 hours. These temperature, moisture, and voltage bias conditions allow PVEL to evaluate degradation related to increased leakage currents.
Thermal Cycling Overview
In the 2020 report, PVEL noted strong results from a host of wafer, cell and module varieties such as standard and half-cut cell module types, as well as thin film, shingled cells, multi-bus bar and heterojunction (HJT) modules. Both glass-glass and glass-backsheet bifacial modules achieved Top Performer status in the 2020 TC tests and that a total of 54 different modules were recognised as Top Performers.
In PVEL’s thermal cycling test sequence, modules are placed in an environmental chamber where the temperature is lowered to -40°C, dwelled, then increased to 85°C and dwelled again. Maximum power current is applied to the modules while the temperature is increased and decreased.
A total of 600 cycles, repeated 200 times over three periods is said to equate to about 84 days in the climate chamber.
