108 megawatts of community solar across 101 projects were installed through 2016

Community Solar


Community solar has become a critical tool for bridging the gap between those who can and can’t access local, affordable, clean energy. Community solar enables multiple customers to participate in a single solar project located in their community, and receive credits on their utility bill for their portion of the power produced. This opens up the opportunity for going solar to those who may be otherwise constrained by the physical attributes of their home or business, like roof space, shading, or property ownership. As a result, community solar projects provide American homeowners, renters, and businesses access to the benefits of solar energy generation and can play a critical role in expanding access to solar energy to low-income households.

Quick facts

Shared renewables projects are often located on public or jointly-owned property, and can be an easier way for renters and condominium owners to benefit from a local solar energy project. There are many reasons why shared renewables might be preferred for a home, business, or individual. Here are a few examples:

  • Those who are only renting may be prohibited from installing solar on the property
  • The roof may be too shaded or needs re-roofing
  • The size or orientation of the roof may be improper
  • Some commercial buildings have equipment on the roof, obstructing an installation

Shared Renewables Models

There are various shared renewable energy models. Here are a few:

Utility-Sponsored Model

Some utilities provide their customers with the option to purchase renewable energy from a shared facility. The customer may purchase a set amount of electricity at a fixed rate for a long term, such as 20 years. The rate, while typically slightly higher that the current retail rate, may provide protection and stability against rising rates for grid electricity. 

On-bill Crediting

One shared renewable energy model involves enabling residents and business to invest in a portion of a shared renewable farm, and receive a credit for that portion of the energy production from the facility on their utility bill.

Special Purpose Entity (SPE) Model

Individuals join in a business enterprise to develop a shared renewables project.

Non-Profit “Buy a Brick” Model

In this model, donors contribute to a shared renewables installation owned by a charitable non-profit organization.
