When installing a solar PV system for your home or business, it’s important to know about solar racking systems.  A solar-racking system secures your solar panels to either your roof or to the ground depending on your individual location.  These systems are designed to easily fit existing rooftops and other structures.

What you need to know.

  • Solar Panels are classified as “Components & Cladding” in the building code and as such, must be fully integrated into the building structure.  You cannot just nail the solar panels to the roof and walk away.
  • Each component must be able to withstand hurricane-force winds, pounding rain, the corrosive effects of salt air and in some climates, heavy snow loads.
  • There are two types of solar racking systems:  1)  Roof Mounting – where the Solar Panels (also known as the solar array) is installed parallel to the roof with a few inch gap.  Note: it is important to have the solar array on the side of the roof that is facing the sun most often. 2) Ground Mounting:  Ground Mounts are usually for large-scale utility stations and attached directly to a ground foundation.

There are three components to solar racking systems:

  1. Roof/Ground Attachments (also known as roof mounts).  Roof mounts vary in color and style depending on the type of roof you own (i.e. slate, tile, asphalt, etc).  At Hilton Head Solar, we use flashing and L-brackets with our roof mounts.  This assures a low-profile installation that is close to the roof while providing adequate airflow behind the panels.
  2. Mounting rails: At Hilton Head Solar, we use black aluminum mounting rails engineered to handle the various weather conditions in our area.  Our rails are also anodized to guard against surface damage and corrosion while providing a clean, sleek finish.
  3. Module clamps:  These clamps secure the top surface of the solar module to a slot in the mounting rail.  At Hilton Head Solar, we use the finest quality clamps that actually make a grounding connection to the module providing an extra layer of electrical safety.

Installing a solar PV system is complicated.  Don’t let just anyone get on your roof and attempt to do the work.  You need a company you can trust.  You need a company that doesn’t sub-contract the installation work.  You need Hilton Head Solar.
