Distributed PV System Optimization
Distributed optimization products, including microinverters, dc-to-dc products and two-stage inverters, fundamentally change the way PV systems are implemented and managed. Is this a bona fide revolution or a solution in search of a problem? Manufacturers provide insights into their products that promise smarter, safer and more costeffective systems, while other industry stakeholders offer their perspectives.

Crystalline Silicon Photovoltaic Modules
After another year on the module roller coaster, there are more manufacturers, more model numbers and more connector types than ever before. Priceper- watt has tracked steeply downhill and may or may not be leveling out. While it is difficult to know what lies around the next turn, rest assured that the ride will be interesting. We review equipment trends and make a case for the industry to demand additional product data in the future.
