Open to every solar installer. You don’t have to join to attend.
The industry calls local and regional installers the long tail. We see the backbone of a stronger solar industry.
Local and regional installers keep solar competitive, serve their communities, and give homeowners more choice. But too often, they lack the pricing, access, and support available to larger players.
Every Alliance partner signs the Strong Tail Compact, a shared commitment to help local and regional installers build businesses that last.
The Strong Tail Compact
1
We serve homeowners and installers, not just transactions.
Success means installer businesses that last and homeowners who remain satisfied.
2
We believe in transparency, not surprises.
Clear pricing, terms, lead times, and performance data.
3
We honor our commitments after the sale.
Our obligations don’t disappear when the transaction is over.
4
We build for the local and regional installer.
Local and regional installers deserve the pricing, access, and support extended to the industry’s largest accounts.
5
We choose the durable business over the fast one.
We don’t sell what we can’t stand behind.

Before you join
Questions installers ask first
What does it cost to join?
Nothing.
Do I have to be an approved OneEthos installer?
Yes. Approval is how you join the Alliance, and it is what gives you access
to the partner offers and to the financing available through OneEthos. If you are already
approved, you do not apply again.
Do I have to use every Alliance partner?
No. Activate the programs that fit your business.
Do I need to use a particular lender?
Some project-level terms require a Loan ID from a OneEthos-approved lender.
Others are company-wide. Each partner page explains what applies.
I’m already approved with OneEthos. Do I apply again?
No. Tell us who you are and we’ll help activate the Alliance programs you
want.
Can I attend the webinars without joining?
Yes. Alliance education is open to everyone.
