CHANGZHOU, China, July 30, 2021 /PRNewswire=KYODO JBN/ --

Recently, Trina Solar released a series of testing results on the mechanical

reliability of the 670W Vertex module. Covering six tests, including static

mechanical load test and five rigorous tests including non-uniform snow-load

test, extreme low-temperature mechanical Load test, hail test, extreme DML test

and extreme wind tunnel test, the serial testing results achieved an

across-the-board verification of the excellent mechanical load reliability of

the 670W Vertex modules.

Photovoltaic modules can be affected by multiple environmental factors in

actual outdoor use, while extreme weather such as snowstorms and gale-force or

higher winds necessitates a higher load performance. As a result, to protect

the interests of the customers, module design needs to consider the ability to

withstand extreme weather over the whole life cycle.

In May of this year, PV Evolution Labs (PVEL), one of the leading independent

PV test laboratories, released its seventh annual global PV module test

results, the 2021 PV Module Reliability Scorecard Report. Trina Solar again

placed as a Top Performer for outstanding product reliability and performance

among global PV module manufacturers. Dr. Zhang Yingbin, Head of Product

Strategy and Marketing at Trina Solar said that completing the general

reliability verification covered all the basics, while the advanced testing in

this go-around was to verify that ultra-high-power modules can maintain their

outstanding performance even when subject to extreme weather, creating one of

the industry's most reliable modules.

Among the lineup of rigid tests, the non-uniform snow-load test simulated

uneven pressures caused by a large accumulation of heavy snow on the Trina

Solar's 670W module surface, with the highest pressure applied to the bottom

end of the module of up to 7000Pa (equivalent to a depth of 2.8 meters of

snow), with the results showing that the power attenuation of the module is

only 0.56%.

The extreme low-temperature mechanical Load test, a static load testing of

positive 5400Pa/ negative 2400Pa under an extremely low -40°C, showed no

variation in electroluminescence (EL) and power attenuation of only 0.11%.

In the hail test that simulates the impact of hail of different sizes on

modules, the 670W module eventually passed the test measuring the impact of

hailstones 35 mm in diameter without causing any damage.

In multiple extreme dynamic mechanical load test, 210 Vertex 670W module

delivered better performance than competitors' modules with load capacity

several times higher than the IEC standard. When installed by clamps, the 210

mm Vertex 670W double-glass module has passed the 20,000 cycles, 20-fold

extreme testing, still remaining intact.

In extreme wind tunnel test, the 670W Vertex module remains intact when the

wind speed reached 62m/s (216km/h or 134 mph), passing the extreme wind speed

test equivalent to the low end of a Category 4 hurricane on the Saffir-Simpson

scale.

Maintaining the consistent ultra-high reliability of Trina Solar modules, the

210 Vertex series modules integrated a series of design optimizations,

including added frame wall thickness, larger cavities, optimized material

selection and matching designs, to ensure ultra-high structural robustness.

Through the series of rigid tests, the series' excellent ability to withstand

external mechanical stress that can calmly handle extreme wind, snowstorms,

extreme cold, hail and other extreme weather was confirmed.

"As the component with the highest power output in mass production in the

industry, the reason we chose 670W Vertex module as a testing object is not

only to empower customers to intuitively understand the high reliability of

670W+ modules, but also to share research results across the whole of the

industry for continuous innovation, comprehensive application of 600W+ modules

and supporting carbon neutral." said Dr. Zhang Yingbin.
