Solar United Neighbors: Solar Co-Ops, Group Buying and Free Homeowner Education
What Solar United Neighbors offers, how group solar purchasing works, and why available co-ops vary by location.

Understanding Solar United Neighbors
Solar United Neighbors provides consumer education, advocacy and options for group purchasing of solar. Its resources can help households learn the questions to ask about equipment, pricing and installer agreements.
Educational support does not mean that every homeowner receives a government grant or no-cost installation. Review the specific program terms for the state or local group you are considering.
How solar co-ops work
SUN describes group models in which neighbors organize to evaluate solar purchasing together. A co-op can help participating households evaluate bids and potentially obtain group pricing while each homeowner signs their own individual installation contract.
Joining a group is not the same as having an installation approved, and a discount does not automatically mean the proposal is financially superior. Request the cash price, total financed price, production estimates, warranties and interconnection assumptions.
Check whether a local group is active
SUN publishes a live directory of solar groups. Availability changes by state and over time. Check whether a group currently accepts your address and confirm its enrollment terms directly with SUN; nationwide education does not establish that a California or Los Angeles co-op is currently open.
If no group is nearby, SUN offers additional learning resources and ways to express interest. Check the current live co-op page for availability instead of relying on an old article.
Use nonprofit guidance alongside careful evaluation
Compare multiple bids where possible, inspect contractor licensing and ask how the proposal handles batteries, roof work, utility approvals and future service. A group process may improve access to information but cannot remove household-specific engineering and financial considerations.
Retain written contracts, proposal assumptions and copies of current consumer-protection resources. Home Solar Simplified is independent of SUN and is describing its resources for educational purposes.
How to evaluate a solar co-op offer before signing
Find an active co-op using SUN's official live list, then ask who chooses the installer, how bids were assessed, how the group price compares with independent offers and what happens if you decide not to proceed.
Ask for your individual cash price, financed total, roof work, warranty obligations, utility export assumptions and cancellation terms. A neighboring homeowner's economics may differ because of roof shading, tariff or household usage.
| Your need | Action | Evidence to keep |
|---|---|---|
| Find an open group | Check SUN's live group directory | Confirm that your address and enrollment date qualify |
| Understand selection | Ask how the installer and group price were chosen | Keep the bid scope and selection explanation |
| Compare your own offer | Request the same equipment and scope from other bidders | Compare cash and financed totals separately |
| Check project responsibilities | Identify roof, permit, utility and service duties | Keep written exclusions and warranty obligations |
| Decide without pressure | Read your individual contract before committing | Confirm cancellation and home-sale provisions |
Frequently asked questions
Are Solar United Neighbors co-ops free to join?
Check the terms of the specific active co-op before joining. Participating in an information or group-purchasing program does not make the equipment or installation free.
Is there a SUN co-op in Los Angeles right now?
Availability changes. Check Solar United Neighbors' official open co-ops directory for a currently accepting Los Angeles-area group rather than relying on a previously published list.
Do group solar purchasers sign separate contracts?
Typically, each homeowner decides whether to proceed with a proposed installer and signs an individual contract. Compare price, financing, warranties and utility assumptions before signing.
