Then, it's time to install the stanchions. With the stanchions in place, the next step is installing the racking to support the solar panels. Trethewey and Warda use aluminum rails for their project, securing them to the stanchions with stainless steel bolts. The bolts should be tight enough to stay secure in tough weather conditions. Each mounting rail must be square to properly align the. Before the panels can go on, their electrical conduit and wiring must be in place. A licensed electrician is often the one doing this work. First, Warda runs conduit from the roof to the home's main electrical panel according to local codes. The necessary wiring will run through them to connect the panels to the electrical system.

Each panel is bulky and heavy, so lifting them onto the roof is often a two-person job. Once each panel is in place, Trethewey and Warda connect it to the microinverter and fasten everything to the rails with clips and clamps. Manufacturers co.
