The U.S. solar installation industry serves residential, commercial, and utility-scale customers by designing, permitting, and installing photovoltaic systems along with battery storage solutions. The sector has grown dramatically due to federal Investment Tax Credits (ITC), state-level incentives, and declining panel costs, though it remains highly fragmented at the local and regional installer level. Lower middle market solar businesses typically focus on residential and light commercial projects and compete on local relationships, permitting speed, and service quality rather than price alone.
