Most solar manufacturing investments fall into the 'Solar Energy Components' category in RMI's Clean Growth Tool—but not all. There are a few investments listed on this map that are for solar inverters, which would fall under the 'Energy Transmission Equipment' category. For the most part, though, investments listed on this map involve the North American Industry Classification System (NAICS) codes for 'Semiconductor and Related Device Manufacturing' (which includes photovoltaic cell manufacturing) and 'Custom Roll Forming', the two industry inputs to 'Solar Energy Components' in RMI's Clean Growth Tool. The overlap in NAICS between photovoltaic cell manufacturing and 'typical' semiconductor manufacturing reflects a real-life similarity in the manufacturing process. There may be slight data redundancies resulting from synthesis of multiple data sources.
