Made in the USA
SolarWorld carries out each step of the module manufacturing process in its Hillsboro, Oregon and international factories. They adhere to the strict quality management, environmental, and occupational health and safety standards ISO 9001, ISO 14001, and OHSAS 18001. By using statistical process controls in every step in the manufacturing process, SolarWorld is able to maintain the highest level of quality.Reliability
SolarWorld carries out many more tests than required by international standards. In fact, every component used must meet at least three times the IEC requirements. These tests help improve the quality of SolarWorld products by providing valuable information on the behavior of their solar modules. IEC tests are regularly performed on random solar modules taken from SolarWorld's production sites to ensure the high reliability of its products even after they are introduced.PID-Free
Potential induced degradation (PID) is a phenomenon where the power output of a solar module is reduced when exposed to high negative voltage bias between the cells and ground. PID can potentially affect the performance of individual modules as well as the overall power output and efficiency of an entire solar power generating system. SolarWorld Sunmodules have been certified as PID-free by 3rd party laboratories.TÜV Rheinland Certified
The TÜV Rheinland “Power Controlled” inspection mark guarantees that an independent test provider certifies that the power ratings specified for SolarWorld solar panels are maintained and regularly monitored. The performance of SolarWorld modules exhibits a mere two percent (2%) measuring tolerance. No other manufacturer can claim such precise performance.High Weight Load Tolerance
With a maximum load capacity of up to 8500 Pa (178 psf), SolarWorld Sunmodules are designed to withstand heavy accumulations of snow and ice.Textured Glass
The proprietary surface coatings and granular texture of the Sunmodule’s front glass create two effects: the reduction of the light reflected from the outside (air-glass interface) and the internal trapping of the light reflected from the solar cells in the module (light-trapping). These two effects combine to make an extremely efficient and high performance PV module.Salt Mist Resistance
SolarWorld Sunmodules have passed the most severe IEC 61701 salt spray test conditions, proving their resistance to salty air and making them ideal for coastal areas.Ammonia Resistance
SolarWorld Sunmodules are ideally suited for long-term use in agricultural applications, as confirmed by the German Agricultural Society and TÜV Rheinland. Laboratory tests have determined that SolarWorld panels can successfully withstand the effects of ammonia inherent in agricultural conditions during a 20-year period.1000 Vdc
The certification to international standards provides additional assurance that SolarWorld panels are suitable for use in systems with greater than 600 Vdc string voltage.
