Silfab passes PVEL’s backsheet durability tests with flying colors

SIL-370 BK

Here’s the SIL-370 BK

North America PV module manufacturer Silfab Solar has excelled in the industry’s most rigorous test for backsheet durability – once again reaffirming the company’s top-notch manufacturing process. Results from PV Evolution Labs (PVEL) that subjected “real-world” stress tests on Silfab MWT modules showed no failures nor any evidence that the company’s backsheets – one of the most essential components of a solar module – would degrade over Silfab’s warranty period.

“We conduct backsheet durability testing as part of PVEL’s Product Qualification Program in order to help PV module buyers and investors avoid the financial consequences of backsheet failure,” said Tristan Erion-Lorico, Head of PV Module Business, PV Evolution Labs. “Congratulations to Silfab Solar on the strong performance of their backsheets in our highly demanding test.”

Why this is a big deal. The backsheet durability sequence conducted by PVEL is the most stringent standard for stress testing used to evaluate whether backsheets in solar modules will continue to electrically insulate and protect the internal components over their expected lifetime of 25-plus years. Silfab Solar, which backs its products with one of the longest and most-trusted warranty programs in the industry, credits these superior test results to its use of high-quality materials and strict quality-control standards applied during the manufacturing process.

The backsheet test applies to the Silfab Solar conventional 60-cell, 120-cell, and 72-cell modules as well as its SIL BL (back-contact, metal wrap-through-MWT) module, all of which provide maximum power density and long-term reliability backed by one of the most trusted warranty programs in the industry. The PVEL test subjects modules to a range of environmental conditions that mimic a 25-year lifespan for rooftop installations.

Silfab has been perfecting PV module technology and manufacturing processes for more than 35 years. In addition to this recent backsheet durability test, Silfab earned “Top Performer” rating in all four categories which appeared on the 2020 PVEL PV Module Reliability Scorecard.

Operating some of the largest highly automated manufacturing plants in North America, Silfab has perfected production methods and secured exclusive agreements with innovators to deliver the most reliable modules on the market. Its current line of mass-production metal wrap-through (MWT) back-contact modules came as the result of a strategic alliance with DSM. Silfab utilizes high-efficiency back-contact solar cells with an integrated conductive backsheet developed by DSM to optimize cell and module power output by reducing front shading and minimizing the charge transfer resistance.
