About

What’s a co-op?

Imagine walking into a solar company’s office with 50 or 100 of your neighbors and saying, “We all want to get solar. What kind of deal can you give us?”

That’s a solar co-op!

In fact, it’s even better than that. In addition to competitive pricing on solar panels, you get:

  • Info to help you understand solar. Our vendor-neutral solar experts are here to help you understand how solar works and make the best decision for your energy needs.
  • A direct line to ask specific questions. You can call or email us anytime you need help. We’ll be here now and long after you install solar.
  • A team that solicits and reviews proposals from solar companies. First, Solar United Neighbors requests bids on your behalf. Then, a committee of your fellow co-op members meet to assess the pros and cons and select the best installer for the group. (Note: If that sounds interesting to you, you’re also welcome to join the selection committee!)
  • Community. You’ll join the growing solar movement. You’ll have a built-in network of support and inspiration from others who, like you, are taking a stand for energy freedom and advancing the clean energy economy.
  • A bigger impact! Going solar creates jobs, and puts energy production and its benefits back in the hands of the people and contributes to cleaner air and water for everyone. A solar co-op amplifies those outcomes exponentially.
