Stion Corp of San Jose, CA, USA, which makes nanostructure-based CIGS (copper indium gallium sulphur-diselenide) thin-film photovoltaic panels, has announced the release and certification of its Elevation 4 module line, which delivers up to 10 percent more energy than conventional crystalline silicon modules with the same power rating. The modules are available in variants ranging from 135 watt to 155 watt in 5 watt increments. Elevation 4 modules are certified to the ANSI/UL 1703, IEC 61730 and IEC 61646 standards.
Stion says that product enhancements enable the Elevation 4 module to provide high energy yield due to an anti-reflective coated glass and temperature coefficient of -0.26%/°C.
The Elevation 4 module uses Stion’s proprietary Circuit Protection System (CPS), which provides significantly improved moisture resistance and lifetime durability over crystalline silicon modules, it is claimed. The modules are also resistant to potential-induced degradation, light-induced degradation, and are engineered to survive in harsh environments and to out-perform in non-ideal situations, claims the firm.
Stion says that its proprietary, monolithically integrated CIGS thin-film solar modules use significantly less energy and raw materials than traditional PV modules and are fully compliant with the European Union Restriction of Hazardous Substances (RoHS) directive.
