How Balance of Systems Technology is Advancing Photovoltaics

The Cleantech Group (CTG), in collaboration with Silicon Valley Bank, has published its i3 solar research report on photovoltaics (PV), PV - Balance of Systems Innovation and Reducing Installed Cost.

The report finds new efficiency gains—the so-called balance of systems that goes into commissioning a solar array—are helping to reduce costs and leading to a dramatic increase in PV global installed capacity.

The report is part of a series of research papers examining sustainable innovation. The conclusions are drawn from a dataset of proprietary intelligence on more than 24,000 companies across all sectors in cleantech, sustainable innovation and resource efficiency.

The Cleantech Group’s i3 market intelligence platform tracks more than $7 billion of deal flow annually across 24,000 cleantech companies, offering subscribers vital information for connecting with entrepreneurs and building an innovation pipeline. Cleantech Forums bring the i3 platform to life by convening thought leaders and innovators around diverse themes.
