With full support of Johnson County and six partner cities, the Midwest Renewable Energy Association (MREA) is hosting a solar group buy in Johnson County, Iowa. The advantage of a group buy is the power of volume purchasing, which can significantly reduce the up-front costs of installing solar on your home. The group buy is open to all Johnson County and West Branch homeowners. 

Dozens of solar group buys have been completed across the country in cities such as Cedar Rapids, Milwaukee, Madison, and Chicago, counties such as Linn County, and in states from California to Vermont. Common elements that have led to success include competitive contractor selection, community-led outreach with a trusted community partner, and a limited-time offering.

Competitive Contractor Selection: Solarize Johnson County’s Advisory Committee is comprised of representatives from the MREA, Johnson County, and most participating cities. The MREA will issue a competitive Request for Proposals and select a single installer to help carry out the program. This way customers get the simplicity of working with a single installer, plus the confidence that the selection process was competitive.

Community-Led Outreach: The program depends on the strong support of Johnson County, local cities and other organizations. Are you part of a neighborhood association, nonprofit organization, school, or workplace that is excited about solar? Help us get the word out by distributing flyers or helping host a Solar Power Hour! Email to get started. Partner cities include Coralville, Iowa City, North Liberty, Shueyville, Solon, and West Branch. Even if your city is not a formal partner, any Johnson County property owner can participate in Solarize Johnson County.

Limited-time Offering: Nothing motivates people like a deadline. Participants have until August 31, 2018 to decide whether to go solar. Installations will take place throughout the program. The time-sensitive nature of the group buy adds urgency into the mix, and helps bring the price down for everyone. How? Read on.


The key ingredient for most participants is the pricing for the group buy. The competitive installer selection process ensures the program achieves a price per watt lower than what any individual would generally be able to get on the market. In addition, the price decreases for everyone in the group buy when certain benchmarks are surpassed.

Pricing offered through the Solarize Johnson County Solar Group Buy is not guaranteed to be the least expensive rate for all solar arrays. Larger solar arrays may be able to achieve stand-alone economies of scale that allow for a lower overall cost. Individuals should consider all their options before signing a contract.

How is a solar installer able to offer such low prices through the program? There are two important factors: strong customer education and an economy of scale. 

Strong Customer Education: Community outreach and education are crucial to program success. MREA, a 501(c)3 nonprofit provides renewable energy training and education, works with local organizations to schedule and facilitate a number of one-hour Solar Power Hours around the community. These events help interested homeowners determine whether solar is right for them. We’ll go over the basics of solar, financials, how to tell if your site is ready for solar, and how to participate in Solarize Johnson County. Getting well-informed participants to the table saves the installer hours and hours of marketing and education they would otherwise have to do themselves, and in turn, saves you money.

Economy of Scale: Just like in a buyers club or co-op, the more people participate, the lower the cost is for the service provider (in this case, a solar installer), and the lower the prices are for participants. Your participation matters, and it always helps when folks talk to their friends and neighbors about the group buy.
