Solar power has become an increasingly popular choice for homeowners and businesses. For sloped roofs, choosing the right PV array mounting system is essential to maximize energy output, ensure durability, and maintain the integrity of the roof.

Why are mounting systems important for sloped roofs?

The foundation of any solar installation is the mounting system, which securely holds the solar panels to the roof while optimizing their orientation for sunlight exposure. On sloped roofs, the mounting system must consider several factors:

1. Structural stability to protect against wind and rain.
2. Ease of installation to minimize labor and time costs.
3. Compatibility with roofing materials such as tile, shingles, or metal.
4. Aesthetic integration to preserve the exterior appearance of the property.

Most Common Mounting System: Track-Based Systems

For sloped roofs, track-based mounting systems are the most commonly used choice. This system features aluminum or stainless steel tracks that run horizontally across the roof. Panels are secured to these tracks using clamps or brackets.

Reasons why track-based systems dominate:

1. Flexibility

   Track-based systems are suitable for a variety of roof types, including tile roofs, asphalt shingle roofs, and metal roofs.

2. Stability

   The track structure evenly distributes the weight of the panels, ensuring a safe installation even on steep slopes.

3. Adjustable Orientation

   Using tracks, installers can adjust the panel angle to optimize sunlight capture, which is especially important on roofs with less than ideal slopes.

4. Easy Maintenance

   Panels attached via tracks can be easily accessed and adjusted for maintenance or upgrades.

5. Cost Effectiveness

   The widespread use of track-based systems has resulted in competitive pricing and standardization, which reduces costs for installers and homeowners.

Components of Track-Based Systems

• Tracks

  Durable metal poles that provide a base for attaching solar panels.

• Rooftop Attachments

  Hooks or brackets that attach tracks to the roof structure.For tile roofs, use specialized tile hooks to minimize roof damage.

• Clamps

  Secure solar panels to tracks. End clamps secure panels at their edges, while middle clamps secure panels placed side by side.

• Flashings and Sealants

  Prevent leaks at roof penetrations and keep them waterproof.

• Other Mounting Systems for Sloped Roofs

  While track-based systems are the most common, there are alternative solutions for specific scenarios:

• Trackless Systems

  Instead of using traditional tracks, these systems use clamps to secure panels directly to rooftop attachments. They are lighter and quicker to install, but may not be suitable for every roof type.

• Ballasted Systems

  Typically used on flat roofs, but on low-slope roofs they can provide a non-penetrating option when roof integrity is a concern.

• Integrated Roof Systems

  Panels are built as part of the roof structure itself, doubling as both roof covering and solar array. These are less common due to higher costs and complex installation.
