How to Install Solar Panels.
The five main steps to installing a solar panel system include an engineering site visit, permits and documentation, ordering equipment, the solar panel installation, and approval and interconnection. [pdf]
Photovoltaic mounting systems (also called solar module racking) are used to fix on surfaces like roofs, building facades, or the ground. These mounting systems generally enable retrofitting of solar panels on roofs or as part of the structure of the building (called ). As the relative costs of solar photovoltaic (PV) modules has dropped, the costs of the racks have become. [pdf]

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 beneath your roof shingles. They’ll. .
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. .
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. [pdf]
