Denver homeowners and small businesses have about one month left to join the Solar United Neighbors (SUN) co-op to get a group rate on solar installation, or simply learn more about going solar.

SUN has a goal of getting 150 co-op members by March 1. As of late-January, the co-op had about 95 members.

“If you’ve ever thought about going solar, now is the time,” said Bryce Carter, Colorado program director for SUN, in a news release. “The solar co-op provides tangible benefits that help transform our electricity system into one that is cleaner, fairer, and shares its benefits more broadly.”

SUN is a nonprofit organization that helps people and small businesses go solar. SUN works nationwide, and its Colorado office is based in Denver.

Since its launch in Colorado in 2019, SUN has facilitated six solar co-ops throughout the state. This current Denver solar co-op is the second for Denver’s residents and small businesses. It is in partnership with the Denver Office of Climate Action, Sustainability & Resiliency; Alpine Bank; Colorado Renewable Energy Society; Vote Solar; Physicians for Social Responsibility-Colorado; New Energy Colorado; and the Northside Sustainability Alliance.

In December, through a competitive bidding process, current members of the Denver solar co-op selected Photon Brothers to be the installer for the group. Members have the option to individually purchase a solar system, electric storage and/or electric vehicle chargers with the group rate – Photon Brothers is currently in the process of developing personalized proposals for each co-op participant.

It is free to join the co-op, and joining does not obligate members to purchase solar, Carter said. Joining the co-op is especially beneficial to learn about what going solar means to you, Carter said in a previous interview. If, for whatever reason, a person or small business decides not to go solar, they can walk away, Carter added.
