Solar group buys spreading in the Midwest
Neighbor‑to‑neighbor solar group buys are scaling across Michigan and the Midwest, creating a pipeline of site assessments, main panel upgrades, and code‑compliant connections that local electricians can tap into. These co‑ops often need trusted contractors for bulk installs and pre‑purchase site work. (winnipegfreepress.com)
Grow Solar’s Midwest program reports 65 group‑buy campaigns across six states since 2013, producing more than 22.4 megawatts of rooftop solar on over 3,400 properties and educating about 14,500 people. (growsolar.org) Solar United Neighbors says it has run roughly 479 completed co‑ops nationally and facilitated more than 11,900 signed contracts and about 101,827 kilowatts of installed rooftop capacity through its groups. (solarunitedneighbors.org) Ann Arbor’s A2ZERO Solarize program has driven roughly 5.2 MW across about 690 residential installations and estimates participants collectively saved more than $2.3 million in upfront costs. (a2gov.org) Minnesota activity is expanding: Solar United Neighbors launched the Fields and Forests co‑op for Cass, Crow Wing, Morrison, Todd and Wadena counties in early March 2026, and SUN has run nearly 30 Minnesota co‑ops since 2018 that led to about 4 MW on ~500 properties and roughly $12 million in local solar spending. (solarunitedneighbors.org) (kaxe.org) Technical assessments tied to group buys frequently trigger electrical service work: Lawrence Berkeley Lab’s July 2024 technical brief highlights electric‑service and panel sizing as a common readiness step for distributed energy resources, and industry sources estimate roughly 20–30% of residential solar projects face main‑panel limitations that can require upgrades. (eta-publications.lbl.gov) (nacleanenergy.com) Cost and lead implications for contractors: industry guidance puts typical main‑panel upgrade costs in the ballpark of $1,500–$4,500 (with other analyses using a $2,000 average), while SUN’s co‑op RFP process gives a winning installer access to an organized pool of roughly 50–200 qualified local leads ready to contract. (surgepv.com) (solarunitedneighbors.org) Municipal programs are pairing with co‑ops: Minneapolis’ Green Cost Share program will match group‑buy projects and offers incentives that can total up to $175,000 per application, creating additional budget and demand signals for installers and pre‑purchase electrical work.
