Commercial & Industrial Solar
What is Commercial-Scale Solar?
Commercial (or Commercial & Industrial/C&I) solar refers to solar energy systems installed on larger buildings, such as:
- Multi-family housing (condos or apartment buildings),
- Commercial property such as office campuses, manufacturing centers, or strip malls, and
- Nonprofit organizations, schools, and government buildings. This group is sometimes referred to as the MUSH (Municipalities, Universities, Schools, and Hospitals) market.

Essentially, any solar built non-residential property is referred to as commercial-scale. These systems are designed to help organizations reduce their electricity costs, lower their carbon footprint, and demonstrate a commitment to sustainability.
Unlike residential solar (which refers to solar powering single-family homes), commercial solar projects are often larger in scale and tailored to meet the specific energy needs of a facility. Systems can be mounted on rooftops, integrated into parking structures (as solar canopies), or installed on available land near a business. When paired with energy storage, the combination system can help larger energy users reduce their demand charges levied by their utility (by lowering their maximum power demand from the grid).
Commercial solar can be financed in several ways—such as through direct ownership, power purchase agreements (PPAs), or third-party leasing—making it accessible to a wide range of organizations regardless of size.

Benefits of Commercial Solar
By generating clean, renewable electricity on-site, commercial solar empowers businesses and institutions to take control of their energy use while contributing to a cleaner energy future.
