Echoing the trend in 2014, transaction activity was strongest among targets categorized as producers of solar energy. Consolidation amongst producers as well as private equity and private investment in solar largely drove demand for solar deals. Geographically, the North American market showed an increase in transaction activity potentially given the recent regulatory and tax incentive dynamics of the U.S. solar industry. While the total number of transactions decreased in 2015, the market dynamics in solar remain supportive for continued interest in M&A.
