What is the true value of commercial solar leads? I have multiple contacts in SoCal and want to continue to bring in business but doesn't look to be fair exchange for time. New in the industry. Here's what I have so far. I want to focus on bringing in new commercial solar business. Solar industry new business COA (cost of acquisition) about 15%? Business referral 2-3% of project size. ($100,000 deal / $2K ?) Seems it should be 5-7% with a signed deal. One warehouse project is equal to 3 houses.
