Once you have approved the design and signed a contract, the solar installer will handle the installation, checking roof structural support, pulling permits, obtaining equipment and scheduling the work. It may be a month or two until installation.
Actual installation is usually completed in one or two days. After required electrical inspections, Eversource will install a net meter and give you approval to power up your system.
