How residential solar is actually sold in the USA
The first call wins
Most American solar leads are not exclusive. A homeowner fills in one form and hears from several companies, or a canvasser catches them at the door and someone else knocks the same street a week later. The company that dials within minutes gets the appointment; the company that dials the next morning gets voicemail. That is not a sales-skill problem, it is a routing problem, and it is solved by making sure every lead has an owner, a timestamp and an escalation path the moment it lands.
The sale is only half the job
After a contract is signed the customer waits. There is a site survey, a permit from the local authority, an interconnection application with the utility, an installation date, an inspection, and finally permission to operate. Weeks pass with nothing visible happening on the roof, and every quiet week increases the chance the customer changes their mind, especially if the rep who sold it has moved on to the next town. Rules on net metering and permitting vary by state and by utility, which makes the timeline different in every territory a company sells into.
