Global automotive supplier Nexteer Automotive has announced it is expanding its product portfolio into the alternative energy market. The company's first product, SunSteer, is a solar tracking actuator and will be built at the company's world headquarters in Saginaw Mich. Nexteer's engineering and manufacturing expertise was applied to the design and development of the device, allowing for world class reliability and performance in this emerging market.
"The team at Nexteer relied on our industry leading automotive technologies to develop a product for the renewable energy market that accurately positions solar arrays to follow the sun", said Vince De Zorzi, senior vice president and chief operations officer at Nexteer.
"SunSteer is built right here in the U.S., with more than 90 percent U.S. content and greater than 50 percent of its content produced in Michigan, including the Great Lakes Bay Region."
SunSteer uses a precision built, high-efficiency ball screw/ball nut combination that provides operating efficiencies of up to 95 percent. This provides the ability to reliably move solar array loads with best-in-class energy consumption.
Under normal operating conditions, SunSteer will accurately track the sun's position, while consuming less than $2.00 of energy per year. High-performance coatings developed under extreme vehicle testing environments are used on SunSteer to reduce corrosion and provide long life field performance of greater than 20 years in the field.
"We found that our products offered levels of reliability and efficiency that were in many cases unprecedented in the alternative energy markets," said David Westphal, executive director for the SunSteer program.
"This has allowed us to develop new product applications that help provide long life expectancy and very low energy losses, both critical needs in the global pursuit of low cost energy."
SunSteer positioning accuracy of less than one degree provides a highly cost effective solution to photovoltaic, concentrated photovoltaic and concentrated solar power. Utilizing Nexteer's advanced electronic power steering technology, SunSteer requires no hydraulic fluids and provides high mechanical load capabilities with minimal environment risk or impact.
"SunSteer fits perfectly into the Great Lakes Bay Region's economic development partnership that focuses on the regional development of comprehensive solar solutions and manufacturers" added De Zorzi.

Bandgap engineering for high-efficiency solar cell design
Washington DC (SPX) Jun 27, 2012
ZnSnP2, an absorber material for solar cells, transitions from an ordered to a disordered structure at high temperatures. Researchers from University College London and the University of Bath have proposed taking advantage of this structural change to design high-efficiency solar absorbers. The team used theoretical calculations to investigate the electronic structure of both phases, and p ... read more
