#SolarMOOC Lecture: Parallel Solar String Design Solutions– Thursday January 10th, 2013

Gene Krzywinski co-founded eIQ Energy (formerly Sympagis Technology) in 2007. Product development focused on solving the “Christmas Tree Light” effect, where solar panels that are connected in series perform at the level of the lowest performing panel, and where a defective panel can bring down the entire string. The goal was to make each panel anindependent power generator that neither affected or was affected by its neighboring panels. However, grid tied inverters need to have a sufficiently high enough input voltage to deliver the appropriate grid AC voltage. Hence the stringing of modules in series to “stack” their voltages.  By boosting the output voltage of each module to a high enough voltage, panels could be connected in parallel, giving them independence from any other module’s operation within the same array.

In 2008, the company succeeded in developing patented technology, the vBoost technology, that accomplished that goal. The technology is applicable to all module technologies and array sizes, even to the extent of permitting multiple technologies and module sizes to feed power to a single central inverter. In addition to the power conditioning, the vBoost provides real time telemetry and reporting, providing  system owners and operators visibility into the real time operation and performance of their installations.

eIQ has over 2.5MW of installed product, including a 1.2MW in central California.

One of the company’s initial showcase installations has over 50kW of crystalline, CdTe and CIGS modules feeding their power into a single, off the shelf Satcon inverter.

Prior to eIQ, Gene was Executive VP of Impala Linear Corporation, a power management semiconductor company that he turned around and sold to Fairchild Semiconductor in 2001, becoming the  Director of Marketing for Fairchild’s Power Management Group.  He was also a cofounder of Advanced Analogic Technologies, Inc. (NASDAQ: AATI), a power management semiconductor company that had its IPO in 2005. Prior to that he cofounded OnChip Systems, an analog semiconductor custom IC design and development company.  Gene’s 30 years of electronics experience also includes Semtech Corporation, Exar Corporation, Ferranti Interdesign and Hewlett Packard Company. He graduated from Rutgers College of Engineering with a BSEE.
