Solar PV Balance of System (BOS) Markets: Technologies, Costs and Leading Companies, 2013-2016

by Stephen Smith, MJ Shiao

Given the state of the global solar PV market, much of the industry's attention has turned to BOS manufacturers to achieve the step-function reductions needed to help solar power deliver energy at or below costs of other generation resources. As a result, BOS manufacturers around the globe are being challenged to offer products at reduced prices, in addition to providing value-added benefits like professional engineering services, highly integrated components and lengthy, robust product warranties.

Not all companies will successfully navigate the next few years. BOS manufacturers are tasked with a difficult set of objectives in order to grow profitably and succeed in a marketplace that expects them to deliver on highly aggressive cost targets within a short period of time. Like the module manufacturer segment, the BOS industry is enduring consolidation amongst companies with complementary offerings and liquidation of other companies that cannot maintain the cost reduction curves in a profitable manner.

Other challenges facing the global BOS manufacturing industry include jurisdictional differences between key markets in the U.S., Germany, Italy, India, China and Australia, which result in the inability of BOS manufacturers to offer single, standardized designs for their products.

Take Five - PV Balance of Systems - Technologies, Costs and Leading Companies, 2013-2016 by Greentech: Take Five

Stephen Smith Solvida Energy Group, Inc.

Stephen Smith is a 15-year veteran of the solar industry. He founded Solvida Energy Group, Inc. – a professional services firm catering to the utility scale and large commercial markets – in January 2009.

Solvida is currently engaged in over 1.5 GW of projects worldwide and has participated in 200+ MW of utility scale projects across the globe. The Solvida team provides clients new to the industry and clients
innovating their position within the industry with consulting, design and engineering, financial modeling, and training services. Solvida played a critical role helping an EPC client win the bid to build the largest operating project in the U.S. and a module manufacturer client sell 130MW into a utility scale project.

Stephen’s seasoned expertise and passion for renewable energy contributes to an inspired and practical approach to his business. He began his career at Powerlight where – from 2000 to 2006 – he amassed
a diverse project portfolio: parking, ground and roof mounts, tracking and fixed arrays and project department revenues grew 400%, and the company’s average project size increased exponentially. He has 
successfully developed more than 50 PV/HCPV solar projects for a broad range of clients - from Fortune 500 companies to state and federal agencies; universities to utilities.

As Managing Partner of Solvida Energy Group, he continues to develop and execute high value solar solutions for a global client base.
