SunPower Corp. (Sunnyvale, CA), a silicon solar-cell performance leader, debuted its new solar-power product line, the SPR-210 and SPR-90, which are the first mass-produced photovoltaic (PV) modules utilizing SunPower’s all-back-contact solar cells. With conversion efficiencies approaching 17%, SunPower’s new modules provide power density, along with an optional “all-black” design that enhances the appearance of roof-mounted PV arrays.
The SPR-210 is SunPower’s flagship product, with total module conversion efficiency approaching 17% and a minimum power rating of 210 W. Designed specifically for use in grid-connected applications such as rooftop systems and power plants, the SPR-210’s high-conversion efficiency allows customers to install more kilowatts of solar power within a limited roof area, while reducing per-kilowatt installation cost. An optional all-black module package, available with a 200 W rating, makes the individual solar cells virtually disappear.
The SPR-90 is a 90 W rated module designed to charge 12 V batteries in remote power applications. The module is designed to deliver higher battery charging current than conventional PV modules over a wide range of weather conditions from a smaller footprint. The high-power density of the SPR-90 modules can reduce the costs typically associated with remote power systems, including transportation, array support structure and installation labor.
Both products utilize SunPower’s A-300 all-back-contact solar cells to generate up to 50% more power than traditional products, and all SunPower modules carry a minimum power rating; the output of every module meets or exceeds its nominal power rating, ensuring that systems will perform as expected. The A-300 solar cell’s low voltage-temperature coefficient, low-light performance and sensitivity to light across the entire solar spectrum means that both SunPower module types convert virtually every accessible photon into useable electricity, maximizing yearly energy production.
“SunPower’s new PV modules set a new industry standard for efficiency and appearance,” said SunPower CEO Tom Werner. “Only SunPower can combine unprecedented area efficiency, exceptional energy delivery over a wide range of real-world weather conditions, and a novel approach to product aesthetics that allows our PV modules to blend into their environment instead of standing out. This is an important milestone for SunPower, as well as the PV industry overall.”
The new SunPower PV modules will be available for delivery in the fourth quarter of 2004.
