IGS Solar is the residential solar finance arm of Dublin, Ohio-based IGS Energy. Since 2017 it has deployed over $1 billion in residential solar lease and PPA assets for ~30,000 homeowners across 10 states, operating as a solar sponsor that originates 25-year leases and PPAs. Its embedded finance footprint is structured project finance (tax-equity / structured-equity partnerships with infrastructure investors like HASI) rather than fintech-style SaaS rails.
