Suntech Power Holdings is introducing a higher voltage PV module, engineered for utility-scale and commercial applications in the US at Solar Power International 2013.
The company launched its Ve-Series module, with 72 multi-crystalline cells at over 300W at last year’s event, specifically designed for utility-scale and commercial markets.
This year, Suntech is touting a 1,500V frameless PV module using a glass-on-glass structure that will be on display at booth #243.
The 60-cell IEC-rated 1,500Vdc module is designed to achieve lower balance of system costs by allowing longer cable runs and longer strings, fewer combiner boxes and smaller wire sizes.
The elimination of the aluminium frame around the modules means that grounding is not required, lowering installation and materials costs of a project as well as removing a key mechanism for Potential Induced Degradation (PID).
Mick McDaniel, managing director of Suntech America said: “This new higher voltage module incorporates the most recent advances in solar technology to enable our partners to install ever more efficient and durable utility and commercial power plants.”
The new 1500V frameless 255W (STP255-20/Wdj) and 250W (STP250-20/Wdj) modules will be available for installation beginning in the first quarter of 2014.
Zep compatible module
Suntech also announced it would be introducing a Zep Solar compatible module at the show. At the heart of the rooftop mounting system is the ‘Zep Groove’ specification, which Suntech has designed into a line of PV modules. This groove joins securely with Zep Solar hardware components for fast and secure installation.
SolarCity recently acquired Zep Solar, while Suntech has been a module supplier to SolarCity in the past.
Suntech said that Zep Solar compatible modules would begin delivery in the first quarter of 2014. These modules, rated at 255W/250W (STP255-20/Wdz), will initially be available in North America.
