How long does it take to install a PV system?
The typical installation time for a residential system is from 2 to 5 days. Systems that are mounted on the ground or systems with batteries are more complex, and might take longer. Most of the installation time is spent on the outside of your house, so there should be little disturbance to you. The installation of commercial systems may take several weeks to over a month to install, depending upon size and type of installation.
