Roof Mounts for Solar Panels

IronRidge Family of Products
A solar panel roof mount (also called a solar racking mount or solar system mount) will hold your solar panels and system in place. The mounting system is a crucial component because it is responsible for securing and stabilizing the solar panels on your roof without compromising the roof’s stability or water tightness.

You want to be completely confident that you have selected a mounting system that can stand up to harsh weather and other factors. Your roof mount is one of the most important ways to protect your investment in solar energy.

The Rundown on Solar Racking: Everything You Need to Know

Solar racking is an essential part of any solar energy system. It is the system that holds the solar panels in place on your roof and ensures they are secure and stable. If you’re considering installing a solar energy system for your home, it’s important to understand the basics of solar racking and how it works. In this blog post, we’ll provide you with an overview of what solar racking is and the different types of solar racking systems available. We’ll also discuss how to choose the best system for your needs.

What is Solar Racking?

Solar racking, also known as PV racking, is the process of mounting solar panels to a structure. This can be a roof, a ground-mounted system or even a pole mount. Solar racking involves choosing and installing the components and systems needed to support and secure your solar array. The type of racking system you need will vary depending on the size and design of your solar array and the installation location. Solar racking systems are designed to withstand different environmental conditions, including wind, rain and snow. They must also provide an adequate amount of support and stability to ensure your solar array remains in place.

Types of Solar Racking:

  • Roof Mounting
  • Ground Mounting
  • Side of Pole Mounting
  • Top of Pole Mounting

When it comes to solar racking systems, there are several different types available depending on your needs. The two most popular types of racking for photovoltaic (PV) systems are ground and roof mounts. Ground mounts are typically used in large-scale solar projects and can be used with tilt angles that range from 0 to 40 degrees. The angle is important as it will determine the amount of sunlight your solar panels will receive over the course of a year. Additionally, ground mounts provide a solid foundation for your solar system since they are not connected to a roof structure. This makes them better suited for areas with high wind speeds or seismic activity.
Roof mounts are the most common type of PV racking and can be mounted directly onto your roof or onto an independent racking structure. Depending on the roof type and size, different mounting systems may need to be used, such as clamping, ballasting, and rail systems. In addition, roof mount systems can also be adjusted to accommodate different roof pitches and tilt angles, which helps maximize the performance of your solar system.

More Info on Roof Mounts for Solar Panels

A roof mounting system may require the following items:

  • Rails - to provide a platform for mounting the modules
  • Splices - to connect rails as needed
  • Mid clamps - to be located between each module
  • End clamps - to secure the end of last module
  • L-feet or standoff - to secure the rail to the roof
  • Flashing - to prevent water leakage
  • Grounding lugs - to run the grounding wire

What Are Solar Panel Mounting Rails?

Solar Panel Mounting Rails are a metal rail that protect solar panels against buckling while safely and efficiently transferring loads from the ground up into the structure. Solar panels experience countless extreme weather conditions throughout their lifetimes. High winds capable of tearing off roofs and snow falls heavy enough to bend metal frames are two weather examples your solar panels may have to deal with.

Their superior spanning capability means they require fewer roof attachments, which reduces the number of roof penetra­tions and the amount of installation time.

Why You Need Clamps & Grounding

Clamps - The module clamps connect the roof attachments to the mounting rail. There are several different types of clamps for each angle and corner on the solar panels.

  • For mid clamps - the number of mid clamps required is equal to one fewer than the number of modules on each row.
  • For end clamps - four are required for each row as end clamps are going to be attached to both ends of each of the two rails.

Grounding - It's extremely important to ground your solar panels and your equipment when you're installing a solar power system. If you experience a lot of lightning storms in your area, grounding your solar system could help prevent damage to your system. Furthermore, the NEC requires that all equipment be electrically bonded and connected to the grounding system to ensure the safety of anyone that might come in contact with a dangerous fault current.
