About How to install photovoltaic panels on the roof for free
Before you begin the installation process, properly plan your solar panel system. This involves assessing your roof’s suitability, determining the number of panels you need, and obtaining the necessary permits.
The first step in the physical installation process is securing the roof attachments supporting the solar panels. First, the installer will find the rafters.
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 the mounting system and electrical components in place, Trethewey and Warda install the solar panels. Each panel is bulky and heavy, so lifting them onto the roof is often a two-person.
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. On the roof, lay out the locations of the stanchions that will support the solar panels.Screw each stanchion through the roof and into a roof rafter. Also, be sure the stanchion flashing fits beneath the roof shingles to prevent leaks.Fasten the upper and lower aluminum rails to the stanchions with stainless steel bolts. Tighten the bolts with an impact driver.Measure diagonally across from the end of the upper rail to the end of the lower rail. Repeat to measure the opposite diagonal distance. Now install the middle rail, aligning it with the upper and lower rail.Run electrical conduit and wiring up to each array of solar panels.Install a micro inverter beneath each solar panel, effectively wiring the panels in parallel with each other, not in series.Securely attach a 6-gauge bare copper grounding wire to each inverter, which will ground the entire system.Make the wire connections from the location of one array of solar panels to the next.Set the solar panel onto the stanchions, snap together the plug connections, then screw the retaining clips to the rails to secure the panel.From inside the basement, complete the electrical work by extending the wires from the solar panels, through a new electrical meter and into an electrical sub-panel.
