How do solar sales reps get paid?

As someone interested in understanding the compensation structure of solar sales representatives, I'm curious to know how exactly they get paid for their efforts. Do they receive a base salary, or is their income solely dependent on commission? Are there any bonuses or incentives in place to encourage higher sales? Additionally, what factors might impact their earning potential, such as the type of solar product they're selling or the region they're working in? It would be great to gain a clearer picture of the financial rewards and challenges faced by solar sales reps in today's market.
