How Community Solar Works
At the heart of community solar programs is a centralized solar energy facility, often referred to as a "solar farm" or "solar garden," that generates electricity for the benefit of multiple participants. This shared solar array is typically constructed on underutilized land or rooftops, harnessing the power of the sun to produce clean, renewable energy.
The solar facility is developed and maintained by specialized solar companies, which then market subscription-based access to the generated electricity to individuals, businesses, and organizations within the local community. Participants subscribe to a portion of the overall solar capacity, purchasing or leasing a share of the array. In return, they receive credits on their utility bills proportional to the solar energy produced by their allocated share.
This flexible model allows community members who may not have the resources or physical space to install their own rooftop solar panels to still enjoy the benefits of renewable energy. By pooling their collective purchasing power, subscribers can access clean electricity at a lower cost compared to traditional utility rates. The community solar provider is responsible for all aspects of the project, from securing land or rooftop space, to financing and constructing the solar array, to managing the subscription program and billing.
Tying into the local utility grid, the solar energy generated by the community-owned facility is fed directly into the electricity distribution network, serving the broader community. This seamless integration ensures that all participants, regardless of their physical location, can benefit from the renewable power produced. The utility company plays a crucial role in this process, collaborating with the solar provider to facilitate grid interconnection, virtual net metering, and the flow of energy credits back to subscribers.
Construction of Solar Arrays
Community solar projects typically involve the construction of large-scale solar arrays, often built on underutilized land or repurposed commercial rooftops. These centralized solar facilities are carefully designed and engineered to harness the power of the sun and generate clean, renewable electricity for the benefit of multiple participants within the local community.
One common approach is to build community solar projects on vacant or abandoned plots of land, known as brownfield sites. These land parcels, which may have been used for industrial or commercial purposes in the past, present excellent opportunities for solar development. Not only are these sites readily available, but their transformation into solar farms also helps revitalize underutilized areas, turning them into productive sources of renewable energy. Brownfield redevelopment minimizes the need to clear pristine land, making community solar projects more sustainable and environmentally responsible.
In urban and suburban settings, community solar developers also frequently choose to construct their arrays on the rooftops of commercial buildings. This approach capitalizes on existing infrastructure and underutilized roof space, enabling the generation of solar power without the need for additional land acquisition. Rooftop community solar projects are particularly well-suited for densely populated areas where ground-mounted installations may be impractical or face zoning restrictions.
