1. Check if certified or not. To become a solar panel installer one must be certified by the recognized organization. They should have completed the courses required to become a solar panel installer.
2. Consult them about the type of system that will best suit your needs. Once it is done the installer will make a proposal and mention all the requirements and the system that is best for your need.
It includes the size of the panels, the number of solar panels, the Kw of your system, and the manufacturer of the solar panels to be used in your new system.
3. Ask them if they have done any installations before. It is important to know if they have carried out any installation before. Ask for testimony or you can try to search for their recent work on their website.
