Commission Structure

TPO Commission Compression Explained

Quick answer

Solar setter and closer commissions are typically funded out of a dealer fee embedded in the loan, averaging roughly 22% in 2026, running roughly $0.05 to $0.15 per watt for setters and $0.20 to $0.50 per watt for closers. As third-party-ownership deals rise from 44% to a projected 65% of sales in 2026, that same commission structure has to work against a deal type with a different owner-claimed credit, while a 40% spike in customer acquisition cost squeezes the pool from the other direction. The result is commission compression on both roles at once.

How the Commission Stack Actually Works

In a standard dealer-network deal, the setter, the rep who books the in-home appointment, earns roughly $0.05 to $0.15 per watt. The closer, who runs the consult and signs the contract, earns roughly $0.20 to $0.50 per watt. Both figures vary by market. A regional manager typically earns an override on top of that on their team's installs. All of it is funded out of the dealer fee, a lender-charged fee embedded in the loan principal that averages roughly 22% in 2026 and adds more than $5,700 to a typical loan balance. The redline is the price-per-watt floor a rep cannot sell below, protecting the margin that funds this entire stack.

What TPO Does to That Math

Third-party-ownership share is projected to hit 65% of sales in 2026, up from 44% in 2025. Customer-owned market share fell from 54% to 43% during 2024 alone, while TPO grew from 40% to 52% in the same period. A TPO deal is structurally different: the tax credit under Section 48E is claimed by the system owner, meaning the installer or financier, not the homeowner. That changes how the deal's economics get split and recomputed, and a commission structure built around loan and cash deals does not translate cleanly.

Regional Swings Show How Fast This Moves

Some markets shifted almost overnight. Michigan went from 1.16% TPO to 38.96% TPO in a single year. Connecticut went from 9.23% to 50.00%. A rep trained entirely on a cash-or-loan pitch has had to relearn the deal structure mid-cycle in markets moving that fast, and the commission conversation moves with it.

CAC Rising at the Same Time Makes It Worse

The dealer fee pool is not just being asked to fund commissions against a changing deal mix. It is being asked to do that while customer acquisition cost spikes 40%, to $0.84 per watt, from a five-year low of $0.60 per watt in 2025. Marketing and sales costs are climbing at the same time the commission structure itself is under pressure, which is why setters and closers in dealer networks are the segment feeling the compression most directly right now.

Why This Pushes Toward Fixed-Price Appointments

A fixed per-appointment price insulates a sales organization from having to relitigate its commission structure every time the cash-versus-TPO mix shifts in a given market. An appointment buyer pays the same rate, $249 after a one-time $300 setup at VA Horizon, whether the homeowner ends up in a loan, a lease, or a PPA. That does not solve commission compression for an in-house sales team, but it removes one variable, the acquisition cost of the appointment itself, from a deal structure that already has enough moving parts.

FAQ

What is dealer fee compression in solar sales?

It is the squeeze on setter and closer commissions that happens when the dealer fee, the pool that funds the whole commission stack and averages roughly 22% of a loan in 2026, has to stretch against both a rising customer acquisition cost and a shifting mix of deal structures at the same time.

How much do solar setters and closers earn per watt?

Setters typically earn roughly $0.05 to $0.15 per watt for booking the appointment, and closers earn roughly $0.20 to $0.50 per watt for signing the contract, both varying by market, according to Everstage. Both are funded out of the dealer fee embedded in the loan.

Why is TPO share rising so fast in solar?

Because Section 48E, the only path left to a 30%-equivalent tax credit after Section 25D expired, is claimed by the system owner. Under a lease or PPA, that owner is the installer or financier, not the homeowner, which is why TPO share is projected to hit 65% of sales in 2026, up from 44% in 2025.

Does buying appointments avoid commission compression?

It removes one variable: a fixed per-appointment price does not change based on whether the deal closes as a loan, lease, or PPA, unlike an in-house commission structure that has to be recalculated as the cash-versus-TPO mix shifts.

A commission rate the TPO shift can't compress.
