Canadaâ€™s Elemex started offering new cadmium telluride (CdTe) solar panels this week for applications in PV facades.
The architectural facade specialist said the modules feature its proprietary unity attachment technology.
â€śSolstex is ideal for tall buildings in urban environments where the footprint is minimized and the roofs are small,â€ť said Hugh Lowry, Elemex special projects engineer. â€śAt just 3.5 pounds per square foot, Solstex panels are easy to install and deliver significantly more energy than other photovoltaic panels.â€ť
According to its product sheet, the panel is available in two versions â€“ Solstex 2000 and Solstex 1200. They are both 6 mm thick. The Solstex 2000 has a power output ranging from 420 W to 450 W and a conversion efficiency of 17.0% to 18.2%. The panelâ€™s short-circuit current is 2.45 to 2.57 ampere and its open-circuit voltage ranges from 218.5 V to 221.1 V. It measures 2,009 mm Ă— 1,232 mm Ă— 79 mm and can generate 16.9 W per square meter.
The Solstex 1200 measures 600 mm Ă— 1,200 mm Ă— 47.5 mm. It offers nominal power of 110 W to 122.5 W and has an efficiency ranging from 15.3% to 17.0%.
Both products are covered by 12-year warranties and 25-year linear performance guarantees, with an annual degradation rate of 0.5%.
The panels are also equipped with rear-ventilated rain screens (RVR). The RVR system is designed to repel water and debris.
â€śPressure-equalization reduces the pressure difference across the cladding through the use of compartmentalization and back venting,â€ť the manufacturer said. â€śIngress of incidental water is reduced and residual moisture is returned to the exterior at the drainage plan.â€ť
