[PDF Version]There are three main employee types that are paid commissions in the solar sales industry. These include: Canvassers: While not directly involved in coordinating sales or transactions, canvassers help with all of the backend work such as lead generation, customer prospecting, and scheduling appointments for sales reps.
Commission Structure for Solar Sales Reps The majority of solar salespeople are paid on a straight commissionpay structure without a base salary. Their commission structure can be a lot more complicated than canvassers and territory managers because their overall sales compensation is based on several different commission calculation methods.
Except in rare sales positions, earning commission has been an expected part of the job. Having skin in the game provides the incentive people need to act with urgency and land new deals. I. Solar Commission Structures: How you pay your solar salespeople matters! I.I. 1. Overall contract price I.II. 2. Percentage of margin I.III. 3.
Therefore, some solar companies calculate their base commission rate on the average solar system size and cost to install the system. Then, they'll couple this base rate with incentive multipliers to encourage better-than-average sales. Say your average system size is 6kW, and your average installation cost per watt is $3.00.
There are several common ways to pay commissioned solar salespeople. Payouts can be set up as a percentage of the overall contract price, based on a percentage of margin, constructed as a combination of contract price commission plus a split of margin above a base price, or reflected as a simple cut of the base contract price. 1.
