What Is Per-Watt Commission?
Per-watt commission is how most solar sales reps get paid, a rate multiplied by the size of the system in watts rather than a flat fee, with setters and closers earning at different rates for different parts of the sale.

Per-Watt Commission explained
Solar sales compensation is typically structured per watt rather than as a flat commission or percentage of contract value. Documented 2026 rates run $0.05 to $0.15 per watt for setters, the reps who book the appointment, and $0.20 to $0.50 per watt for closers, the reps who run the in-home consult and sign the contract, with the exact rate varying by market and by company.
On a typical 8 to 10 kW residential system, that per-watt math translates into real dollar figures fast: a closer commission alone can run well into four figures on a single deal, which is part of why closer roles are the more competitive, more experienced tier of solar sales compared to setter roles.
Commission is also not the whole story. A regional manager override sits above both setter and closer commission, meaning a manager earns an additional cut on every install their team closes, layered on top of the redline, the PPW floor below which a rep cannot sell without cutting into that override and the installer's own margin.
Why it matters when you're buying
If you are deciding whether to build an in-house setter team or buy pre-sat appointments instead, per-watt commission math is the direct comparison point. A setter earning $0.05 to $0.15 per watt has to actually book and often help confirm appointments to earn anything, while a pay-per-sit vendor relationship has a fixed, known cost per completed appointment regardless of system size.
