PV BalancePV Balance of systems (BOS) represent a market value exceeding US$70 billion in 2015 and will exceed US$100 billion by 2020 despite rapidly falling costs, according to GTM Research's latest report, PV Balance of Systems 2015: Technology Trends and Markets in the U.S. and Abroad. This slide-based report highlights key trends and opportunities for reducing PV system costs necessary for driving strong project economics and the expansion of solar globally.

PV balance of systems (BOS) encompass all non-module costs including hardware costs and soft costs consisting of operations and services. From 2007 to 2014, PV module costs have diminished more quickly than PV BOS costs. Whereas blended average module pricing has dropped 79% between 2007 and 2014, BOS costs have been slower to respond, averaging between a 39%-64% drop depending on market sector and geography. Even within the same geography, supply chain complexity and disparity results in high variability in project BOS costs. Best practices are seldom shared and the industry has conflicting views on the best path forward when it comes to reducing component and installation costs.
