Product warranty for modules doubled: SolarWorld sets new standards

Certified quality ensures long-term yield


SolarWorld sets a new industry quality standard and doubles the product warranty for all solar modules to 20 years. With the warranty term, which exceeds the market norm, SolarWorld sets new standards in the solar industry.

“We completely trust our products. That is why we can guarantee our customers that over 20 years, our solar modules will deliver what they promise: strong performance and low electricity generation costs,” explains Dr.-Ing. E. h. Frank Asbeck, CEO of SolarWorld AG. With its extended product warranty, SolarWorld greatly exceeds the industry standard. “We also want to send a signal to the industry that only those who rely on quality can win the trust of investors,” Asbeck continues. Going forward, the extended product warranty applies to all solar modules installed after January 1, 2017. This protects end users against any defects that may be attributable to production faults.

High yield throughout the entire term 
In addition to the extended product warranty, SolarWorld continues to offer its customers a linear performance guarantee. With SolarWorld modules, the so-called degradation value is exceptionally low. For its product range Sunmodule with a robust glass-glass design, SolarWorld therefore guarantees a performance of 86.85 percent even after 30 years. 

Tests that greatly exceed industry standards 
From the incoming goods inspection and production processes monitoring, to the strict tests in the module test laboratory: ensuring product quality comes first at SolarWorld. Reliable durability, low performance loss, no PID, and security against hotspots are the demands placed on solar modules to deliver exceptional yields over decades. No module leaves the SolarWorld production without a tested resistance to salt spray, being frost and hail-proof, and resistance to ammonia, dust and sand.

Certified quality 
Additionally, SolarWorld modules are tested and certified by independent testing institutes. As one of the first manufacturers worldwide, at its site in Freiberg, Germany, SolarWorld is proven to produce according to IEC TS 62941, the quality guideline for PV production. Recently, the Association for Electrical, Electronic + Information Technologies - VDE, also awarded SolarWorld modules the VDE Quality Tested certificate, thus attesting to high reliability, low degradation and optimized functional reliability. These certifications once again independently document the SolarWorld AG promise of high quality.
