The industry calls independent installers the long tail. We see the backbone of a stronger solar industry.
Independent 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 independent 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 independent installer.
Independent 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.
