Commercial and Industrial (C&I) Rooftop Solar
C&I Rooftop Solar Market
The Commercial and Industrial (C&I) rooftop segment is the most commercially attractive frontier in distributed solar right now. Unlike utility-scale projects, C&I solar competes directly against high retail electricity tariffs rather than wholesale power prices, which changes the economics considerably. The market is being propelled by corporate ESG mandates such as RE100 and by volatile grid electricity costs that are keeping CFOs up at night. That said, the segment remains fragmented because of offtaker credit risk and the genuine complexity of executing multi-site national and global rollouts.
