How to Install a Solar Hanger Bolt for Metal Roof Solar Mounting

Installing a solar hanger bolt is a crucial step in securing a solar panel racking system on metal roofs. Follow these steps for a proper and secure installation:

Tools & Materials Needed:

• Solar hanger bolts (pointed head for wooden rafters or flat head for steel purlins)
• L-feet or mounting plate
• Flange nuts & EPDM washer
• Power drill & drill bit (suitable for metal or wood)
• Wrench or socket tool
• Measuring tape & marker

Step-by-Step Installation Guide:

Step 1: Mark the Drilling Points

• Identify the positions where the hanger bolts will be installed.
• Ensure alignment with the solar panel racking layout.
• Mark the spots using a marker or chalk for precision.

Step 2: Drill Pilot Holes

• For wooden rafters: Use an appropriately sized drill bit to create a pilot hole at the marked spot.
• For steel purlins: Pre-drill the hole based on the bolt diameter for easier insertion.

Step 3: Insert the Hanger Bolt

• Insert the solar hanger bolt into the drilled hole.
• Tighten it using a wrench or power tool until it is firmly secured into the roof structure.

Step 4: Secure the EPDM Washer & Flange Nut

• Slide the EPDM washer onto the hanger bolt to create a weatherproof seal against water leaks.
• Attach and tighten the flange nut over the washer to secure the bolt.

Step 5: Attach L-Foot or Mounting Plate

• Mount the L-foot or plate onto the exposed threaded end of the hanger bolt.
• Adjust the height if necessary to align with the racking system.
• Secure it tightly with a flange nut.

Step 6: Verify Stability & Waterproofing

• Ensure all bolts are properly tightened and secure.
• Check that the EPDM washer is compressed to maintain a leak-proof seal.
• Proceed with installing the solar rails and modules.
