First off if you know HomeAdvisor then you can expect the same type of lead structure. 

Leads are shared meaning you purchase a solar lead from modernize for $100+ and that same lead is sold to a few other solar companies. Just like home advisor they will say the lead is shared amongst 3 contractors but in reality they are selling the lead to 5 or more. So that lead should really have cost $20 but you paid $100. Then the bid war begins. 

When you buy exclusive solar leads from Exclusive Leads Agency not only are they not shared AT ALL, but we help our clients nurture the lead by educating them and constant follow up. The cost can vary from $120 to $250 from leads to appointments. Some clients want a solution for their in house team, which we provide all the resources we use to get solar leads.
