Why Community Solar Makes Sense for New Jersey

WIND MEASUREMENTS

    The two community solar models are somewhat different: the bill in the legislature enables the sharing of solar energy produced by a large communal solar installation, while the private initiative involves residents banding together to take advantage of economies of scale in the cost of installing solar on their individual residences.

    But the outcome is the same: homeowners are able to install solar at a reduced cost, as well as to reap the benefits that solar brings in terms of reduced electricity bills, federal tax benefits and a new income stream from the sale of SRECs, or solar renewable energy certificates, a state financial incentive.

    The increased production of solar energy, meanwhile, benefits society by reducing harmful greenhouse gas emissions and by contributing to the development of a robust renewable energy sector that promotes prosperity and national security.

    The community solar concept originated in California, but my company, GeoGenix, has been making an effort to bring it to New Jersey. We have installed community solar at four residential developments in New Jersey, and plans are underway at several more.

    There are cost savings made possible by operational efficiencies, including the need to make only one trip to city hall for permits and the ability to save on labor costs through the streamlined deployment of installation crews. Also, although each home’s system is custom-designed, the similarities in home designs also create efficiencies. 

    The ability to sell to a group is yet another efficiency. Once the initial customers – usually “early adopters” concerned about their carbon footprints – have moved forward, solar tends to sell itself. The natural curiosity of neighbors (often prompted by a the presence of a truck in the neighborhood) usually leads to other sales.

    Although the financial benefit of community solar is an advantage, an equally important advantage is the group support. The community solar concept allows neighbors to easily share information, become acquainted with installers, navigate the complexities of state and federal financial incentives and compare their solar outputs.  

    But in truth, solar is not a hard sell, especially in New Jersey whose generous state incentives have made it a national leader in solar, second only to California in installed solar capacity and first if calculated on a per-capita basis.

    The typical payback for a residential solar system in New Jersey is three to five years, after which the homeowner continues to benefit from free electricity for the lifetime of the system, which is 30 or more years. With electricity costs having nowhere to go but up, a rooftop solar system thus serves as a hedge against electricity rate increases.

    In additon, homeowners benefit from the sale of SRECs for 15 years. SRECs, each of which is the equivalent of 1,000 kilowatt-hours of solar-generated electricity, are a state incentive representing the environmental benefit of solar. SRECs are sold to utilities, which are required to meet state mandates for the production of electricity from renewable sources. 

    While most homeowners initially consider solar out of concern for the environment, it is the 15 to 20 percent return on investment that usually ends up being the deciding factor. In fact, solar is such a good deal in New Jersey that homeowners, once they get a handle on the numbers, can hardly believe they’re for real. 

    As an example, let’s take Somerset Run, an age-restricted community in the Somerset section of Franklin Township, where GeoGenix recently completed a community solar project of 10 homes collectively representing 80 kilowatts of generating capacity that is expected to produce nearly 100,000 kilowatt-hours of electricity annually.
