Every successful solar roof installation depends on the precision and reliability of its mounting accessories.
From ganchos de techo to rails, clamps, and grounding parts, each component plays a vital role in ensuring that the system performs safely for decades.

1. Overview of Roof Mounting Accessories

A roof mounting system connects solar panels to the roof structure through multiple accessories.
Each accessory has a specific mechanical function and must match the roof type.

Main components include:

1. Roof hooks or L-feet
2. Mounting rails
3. Mid clamps and end clamps
4. Rail splices and grounding clips
5. Waterproof flashing or sealing parts

2. Roof Hooks and L-Feet – The Foundation

These are the base connection parts that fix rails to the roof.
They determine the system’s overall stability and waterproofing performance.

Tip: PV Mounts offers both fixed and adjustable stainless steel hooks for different tile profiles.

3. Mounting Rails – The Structural Backbone

Rails are extruded aluminum profiles that carry the weight of solar panels and transfer loads to the roof hooks.

• Standard materials: Al6005-T5 anodized
• Available lengths: 2.1m / 3.2m / 4.2m/4.8m etc
• Surface finish: ≥10μm anodized for corrosion protection

👉 Compatible with PV Mounts mid clamps, end clamps, and grounding accessories.

4. Mid Clamps and End Clamps – The Locking System

These clamps fix the solar module frames onto the rails.

Always use spring nuts o T-bolts that fit the rail’s slot width to prevent loosening.

5. Grounding Accessories

Electrical safety is critical.
Use grounding clips o lugs to ensure all panels and rails share a common grounding path.

• Grounding clip: cuts oxide layer and ensures continuity
• Grounding lug: connects to copper wire or grounding conductor
• All stainless steel hardware to avoid corrosion

6. Waterproof Flashing and EPDM Seals

To protect roof integrity:

• Use flashing plates under hooks for tile/shingle roofs
• Apply EPDM rubber pads under L-feet for metal roofs
• Seal all penetrations with UV-resistant silicone

7. Full Accessory Compatibility

PV Mounts accessories are designed as a complete modular system — every hook, rail, clamp, and grounding part matches perfectly.

✅ ISO 9001 certified
✅ Salt spray tested ≥720h
✅ Suitable for tile, metal, or flat roofs

8. Why Quality Accessories Matter

• Prevent roof leaks and corrosion
• Ensure uniform panel alignment
• Reduce installation time
• Extend overall system lifespan

Using certified, precision-made components helps EPCs and installers avoid costly rework and warranty claims.

9. Conclusión

A reliable solar mounting system starts with quality accessories — each small component contributes to long-term safety and efficiency.

FAQ – Roof Mounting Accessories

Q1: Are all accessories compatible across brands?
Not always. Rail slots and bolt sizes differ by brand — using a unified PV Mounts system ensures full compatibility.

Q2: Can L-feet be used for both tile and metal roofs?
They’re primarily for metal roofs, but can work with flat tile roofs using sealing pads.

Q3: What’s the difference between mid and end clamps?
Mid clamps secure panels between modules; end clamps secure the outermost panels on each row.

Q4: How to ensure grounding safety?
Use certified grounding clips and check resistance continuity (<25mΩ) between rails and panels.
