Sunpreme Launches Premium Solar 2.0 Maxima GxB Solar Modules with Outstanding Aesthetics, Ruggedness and Bi-facial Energy Boost
Mar 5 14
Sunpreme is launching the Maxima GxB-340W and GxB-280W bi-facial modules. They utilize the third generation embodiment of Sunpreme's 156mm HCT based PV cells, packaged in frameless, double glass modules, and designed to meet the growing need for high-performance, cost efficient PV panels in space-constrained roof top and distributed generation applications. At present, this market is served by a very small number of suppliers capable of Solar 2.0 technologies, with demand out-stripping supply. The Sunpreme Solar 2.0 HCT bi-facial cells come with initial production level cell efficiencies of around 21%, for front illumination only, resulting in modules with nameplate outputs ranging from 330W to 350W DC for 72 cell modules. With a simple bi-facial mounting configuration, there is an additional boost in the AC energy output due to power generated from back side of the cell capturing reflected and diffused lights; this can range up to 20% over PVSyst model predictions. Moreover, a second performance bonus accrues from the modules' low thermal coefficient for power degradation, measured at -0.33%/C. The company announced that its Maxima GxB products are ready now for volume shipments. Both the GxB-340W and GxB-280W were fully certified to UL, IEC reliability and safety standards and are CEC listed. All Sunpreme modules are covered by a warranty backed by the Munich Re Insurance. Pre-launch customer momentum has been quite positive, with close to 1 MW worth of pre-booked orders ready to deliver over the next few weeks. Applications include commercial structures and ground mounts in high albedo areas. Demonstrated ruggedness to withstand extremes of cold as well as hot, dusty environments, early shipments include those for use in Alaska and the Middle East regions. Recognizing the outstanding wind resistance of these double glass frameless modules at 300 km/h (versus benchmark 200 km/h), repeat orders have been also received from the Caribbean.
