An in-depth guide on overcoming challenges with tile roof solar installations, including detailed installation methods, classification schemes, and key construction steps.
Challenge:
Solutions:
Non-cutting special fixtures (breakage rate < 3%)
Slope adaptation for 15° – 60°
Triple waterproofing: Original tile reset, butyl tape, stainless steel waterproof cover
Option 1. Terracotta/Glazed Tile Roofs:
Hook Lifting Method (Recommended): Insert stainless steel hooks into roof beams, create ventilation layer
Through-Type Installation: Only for reinforced tiles (≥ 20mm thick); seal with EPDM rings after drilling
Option 2. Asphalt Shingle Roofs:
Option 3. Flat Tile Roofs:
Step 1. Roof Survey:
Inspect wooden rafter spacing (≤60cm) and purlin condition.
Replace if tile damage >10%.
Measure slope: 30° – 40° ideal; > 50° requires anti-slip baffles.
Step 2. Method Installation Steps:
Displace tiles carefully with suction tool.
Install stainless steel L-hooks (depth ≥ 50mm into rafters).
Level aluminum alloy brackets with ≤ 1° slope error.
Reset tiles, cut for support holes, apply elastic sealant.
Take note of Electrical Safety:
Route cables along roof ridge in metal flex tubes to prevent rodent damage.
Use double-circuit grounding linked to the building's lightning protection.
