Canadian Solar is introducing a new, glass/glass 1500V multicrystalline PV module at Solar Power International (SPI). The ‘Diamond’ module is designed for harsh environments as well as providing lower degradation over a 30-year lifespan, while enabling the use of longer strings with fewer combiners, cables, and other system parts to reduce the overall balance of systems (BOS).
Increased PV module reliability and lower degradation over its lifecycle enables improved performance even in harsh environments. Replacing conventional backsheet materials and using thinner, tempered glass/glass and eliminating the need for an aluminum frame, reduces chances of moisture and other environmental conditions that can degrade module performance prematurely.
The Diamond module uses thin, glass/glass substrates without the need for an aluminum frame and therefore does not require grounding, thereby eliminating the cause of Potential Induced Degradation (PID). In addition, the Diamond module has the ability to withstand harsh environmental conditions, including high humidity, high temperature, sandstorm, and ultraviolet (UV) conditions. The module's increased resistance to salt corrosion translates into a more robust and reliable solution for coastal system installation. Rated for 1500V systems, the Diamond module significantly reduces Balance of System (BOS) costs by increasing modules in a string and decreasing the number of combiners, cables, and other system parts.
The glass/glass cell encapsulation blocks moisture permeability, enhancing long-term system performance reliability. The first year annual power degradation is 2.5% and 0.5% each year afterwards. With that, module output at the 25th year is maintained at 85% versus the current 80%.
Officially to be launched in early 2015 after IEC, UL and CEC certification.
