Trina Solar’s mega 670W Solar Panels are passing stress assessments

When we obtained photo voltaic on our home in February final 12 months, we selected 20x 325W photo voltaic panels to create our 6.5kW system. By comparability, Trina Solar has a brand new photo voltaic panel that could be a large 670W per panel. With the next capability, you’ll be able to obtain the identical power assortment with fewer panels and a smaller footprint, or alternatively obtain a a lot bigger system in the identical bodily house as much less environment friendly panels.

Before going onto properties and companies, new photo voltaic panels undergo a sequence of assessments to make sure they stand up to the tough components they’re more likely to be uncovered to, all through their life.

Results from six latest assessments present that Trina  Solar Vertex 670W modules have glorious mechanical load reliability. The six assessments included static mechanical load testing, non-uniform snow-load testing, excessive low-temperature mechanical load testing, hail testing, excessive dynamic mechanical load (DML) testing and excessive wind tunnel testing.  

The sequence of assessments verified, across-the-board, the wonderful mechanical load reliability of 670W Vertex modules. 

Outdoor photovoltaic modules may be affected by a number of environmental elements. Extreme climate equivalent to snowstorms and gale-force or increased winds necessitates a  increased load efficiency. As a outcome, the modules’ design wants to resist excessive climate over the product’s lifecycle. 

In May of this 12 months, PV Evolution Labs (PVEL), one of many main unbiased PV take a look at laboratories, launched its seventh annual international PV module take a look at outcomes, known as the 2021 PV Module Reliability Scorecard Report. Trina Solar was a ‘top performer’ for excellent product reliability and efficiency amongst international PV module producers.

Dr Zhang Yingbin, head of product technique and advertising at Trina Solar, says finishing the final reliability verification lined all of the fundamentals, whereas the superior testing verified that the ultra-high-power modules can preserve excellent efficiency even when topic to excessive climate. 

Among the lineup of assessments, the non-uniform snow-load take a look at simulated uneven pressures brought on by a big accumulation of heavy snow on the Trina Solar’s 670W  module floor. The highest strain was utilized to the underside finish of the module of as much as 7000Pa (equal to a depth of two.8 meters of snow), with the outcomes displaying that the ability attenuation of the module is simply 0.56%.

The excessive low-temperature mechanical load take a look at, a static load testing of constructive 5400Pa/ unfavourable 2400Pa underneath an especially low – 40°C, confirmed no variation in electroluminescence (EL) and energy attenuation of solely 0.11%. 

In the hail take a look at, which simulates the affect of hail of various sizes on modules, the 210 Vertex 670W module handed the take a look at measuring the affect of hailstones 35 mm in diameter with out inflicting any harm.  

In a number of excessive dynamic mechanical load testing, 210 Vertex 670W modules delivered higher efficiency than opponents’ modules with load capability a number of occasions increased than the IEC normal. When put in by clamps, the 210 Vertex 670W  double-glass module handed the 20,000 cycles, 20-fold excessive testing, nonetheless remaining intact.  

In the intense wind tunnel take a look at, the 210 Vertex 670W module stays intact when the wind pace reached 62m/s (216km/h or 134 mph), passing the intense wind pace take a look at equal to the low finish of a Category 4 hurricane on the Saffir-Simpson scale. 

Maintaining the constant ultra-high reliability of Trina Solar modules, the 210 Vertex sequence modules integrates a sequence of design optimizations, together with added body wall thickness, bigger cavities, optimized materials choice and matching designs, to make sure ultra-high structural robustness. The assessments confirmed the Vertex product sequence’ glorious skill to resist exterior mechanical stress together with excessive wind, snowstorms, excessive chilly, hail and different excessive climate. 

“The reason we chose to do these tests of the 670W Vertex modules is not only to empower customers to understand the high reliability of 670W+ modules, but also to share research results across the whole of the industry for continuous innovation and comprehensive application of 600W+ modules,” says Zhang.
