This allows you to work with their administrative team and potentially get to know some of the team members who will be spending some time on your roof.

Ask who will be installing your system if the company isn’t willing to send a representative or sends a sales representative.

Ask the company how long the team has worked together, whether projects often go smoothly, and what to do if there are any problems during installation.

These inquiries should help you determine how accommodating the firm will be if things don’t work out as expected.

Local installers are considerably more likely to visit the site and send someone skilled in solar energy array installation.

#Obtain three quotes, preferably more.

Do not, under any circumstances, sign a contract with the first solar contractor that comes to your house or drops a flier in your mailbox. Get at least three quotes, preferably more, by shopping about.

Check to see if these quotes are for the same size and style of solar installation as much as you can. You can compare like with like in this manner.

Ask why one company recommends a system that is significantly larger or smaller than the others. And consider that when making your choice if a business provides an estimate without a site visit.

A system can be designed by qualified solar contractors to maximize solar collection by considering factors like the size, orientation, and tilt of your roof.
