Snow guards are essential components for ensuring the safe and efficient performance of solar panel systems, particularly in regions that experience heavy snowfall. While snow can be a valuable source of water in some parts of the world, it can also create problems when it accumulates on roofs or solar panels. Snow guards help mitigate these risks by preventing large amounts of snow from sliding off the roof suddenly, which could potentially damage the solar panels or create hazards for people and property below.

1. What Are Snow Guards and Why Are They Important?

Snow guards are devices that are installed on the roof to control the movement of snow. They prevent snow from sliding off the roof too quickly, which can cause damage to the solar panels, gutters, and surrounding areas. Snow guards are especially important for homes and businesses located in snow-prone areas. The primary functions of snow guards include:

• Preventing avalanches of snow from sliding off the roof, which could damage solar panels, gutters, or landscaping.
• Ensuring the safety of pedestrians and vehicles by preventing falling snow or ice.
• Protecting solar panels by minimizing the risk of sudden snow slides, which could cause cracking or displacement of the panels.

2. Different Types of Snow Guards

There are several types of snow guards, each with its own design and application. The most common types include:

A. Surface-Mount Snow Guards

• Installation: Surface-mount snow guards are attached directly to the roof’s surface, typically using adhesive, screws, or other fasteners.
• Best For: Flat or low-sloped roofs where snow accumulation is moderate.
• Material: Typically made from plastic, aluminum, or stainless steel for durability.

B. Under-Rail Snow Guards

• Installation: These are installed under the solar panel rails. They work by preventing snow from sliding beneath the panels and creating excessive weight buildup.
• Best For: Solar installations where panels are mounted in a fixed position.
• Material: Made of galvanized steel or stainless steel for corrosion resistance.

C. Snow Fences

• Installation: Snow fences are larger, grid-like barriers placed along the edges of the roof to prevent snow from sliding off in large chunks.
• Best For: Sloped roofs with heavy snow accumulation.
• Material: Usually made of metal or heavy-duty plastic.

3. How to Install Snow Guards

Proper installation is essential to ensure that snow guards perform effectively. Here’s a step-by-step guide on how to properly install snow guards on a roof with a solar panel system.

Step 1: Assess the Roof and Solar Panel Layout

Before installing snow guards, it’s important to assess the roof’s slope, the type of solar panel installation, and the snow load in your region. If the roof has a steep slope, snow is more likely to slide off quickly, so a more substantial snow guard system will be needed. Similarly, if you have a flat roof, you may need a combination of ballasted snow guards and roof-edge protection.

• For solar systems, snow guards should be installed below the solar panels and along areas that tend to accumulate snow, especially where the panels meet the roof.

Step 2: Choose the Right Snow Guard System

Select the right type of snow guard based on the type of roof you have, the expected snow load, and your solar panel configuration. For example:

• Surface-mount snow guards may be enough for a low-slope roof.
• Under-rail snow guards are best for solar arrays with adjustable or fixed rails.
• Snow fences are ideal for steep roofs with heavy snowfall.

SIC Solar offers customizable mounting solutions, including snow guard systems that are tailored for solar installations to prevent snow and ice buildup, ensuring the longevity and performance of the panels.

Step 3: Install the Snow Guards

The installation process will vary depending on the type of snow guard chosen:

• Surface-Mount Snow Guards:

  1. Mark the placement of the guards along the roof’s surface or solar panel array.
  2. Drill pilot holes for the screws or fasteners, ensuring they are properly aligned with the roof trusses or rafters.
  3. Apply adhesive (if recommended) or securely attach the snow guards with screws.
  4. Ensure a uniform spacing between the guards to evenly distribute the snow load.

• Under-Rail Snow Guards:

  1. Place the guards under the solar panel rails, ensuring that they are installed parallel to the roof slope.
  2. Attach the guards securely to the mounting system, ensuring they do not interfere with the panels’ positioning.
  3. Check that the rails are properly tightened and aligned to ensure that the snow guard remains effective.

• Snow Fences:

  1. Measure and mark the roof edges where you want to install the fence.
  2. Install the snow fence with the appropriate fasteners, ensuring it is securely attached to withstand wind and snow pressure.

Step 4: Test the Installation

Once installed, test the snow guards to make sure they are secure and in the correct position. You may want to simulate light snowfall or check the system after a snowstorm to ensure everything is functioning properly.
