Nanosolar releases new printed CIGS efficiency benchmarks

"Our mission is to produce the most cost efficient solar power possible," said Geoff Tate, CEO of Nanosolar, Inc. "We are doing this through our printed CIGS technology, innovative panel design and sound manufacturing decisions that lower panel costs in tandem with balance of system costs." Nanosolar prints its proprietary CIGS and nanoparticle inks directly onto low-cost aluminum foil, both faster and more cost-effectively than with traditional high-vacuum manufacturing equipment. Both NREL and ISE recently measured these solar cells at slightly below 14 percent efficiency.      

Using the latest in robotic manufacturing practices, Nanosolar assembles these electrically-matched, all-back-contact thin film solar cells into uniform, high quality solar panels using its efficient and cost-effective metal wrap through process at assembly factories that can be located at the point of panel demand.      

Nanosolar will reach an annual manufacturing capacity of 115 megawatts by autumn 2011. Nanosolar is currently shipping 10 percent efficient, 200 W panels in volume with plans to reach 11 percent and 12 percent efficiencies in volume within the next 12 months.      

The Nanosolar Utility Panel’s design reduces mounting hardware costs, wiring cable volume, and required installation labor in multi-megawatt installations.      

The Nanosolar Utility Panel has two pieces of durable, tempered glass versus one tempered glass sheet for most thin film panels, uses two edge connectors as opposed to a standard junction box, and produces more power and operates at a far lower voltage than standard thin film panels. In addition, it is the first solar panel to be certified by TUV to operate at up to 1500 system volts. These unique system design features allow for balance of systems cost savings of up to 30 percent over competing thin film solar panels in utility-scale power plants.      

Nanosolar recently signed a panel warranty insurance policy with Munich Re in preparation for future multi-megawatt installations and panel bankability. The panel warranty insurance policy covers Nanosolar’s 2011 factory production and serves as a backstop to Nanosolar’s 25-year limited performance panel warranty.      

"Through our extensive due diligence process, we were impressed with the quality and controls in the Nanosolar manufacturing process," said Christian Scharrer, Head of Green Tech Solutions, Special Enterprise Risks at Munich Re. "We are confident in standing behind the Nanosolar Utility Panel as a credible and bankable technology for low cost utility-scale solar installations."      

As part of its commitment to an effective waste management and recycling policy for the company and its partners, Nanosolar has joined PV Cycle, the leading European organization committed to responsibly recycle solar panels. The Nanosolar Utility Panel has one of the industry’s lowest carbon dioxide and toxic emissions lifecycle footprints, and its energy payback time is less than eight months.
