Installing solar panel brackets and photovoltaic (PV) modules requires technical precision and safety awareness. This guide walks you through the entire process – from site preparation to system activation – while sharing industry best practices adopted by professionals like EK SOLAR in commercial and residential projects.

Essential Tools and Materials

Before starting your solar panel installation, gather these critical components:

• Aluminum mounting brackets (roof-ground-rail types)
• PV modules with IEC 61215 certification
• Weatherproof lag bolts (stainless steel recommended)
• Torque wrench (25-35 Nm range)
• Fall protection harness (OSHA compliant)

Installation Process Breakdown

1. Structural Assessment

• Check roof load capacity (minimum 30 PSF for asphalt shingles)
• Identify rafters using stud finder (16" or 24" spacing)
• Mark drilling points with chalk line

2. Bracket Mounting

For pitched roofs:

• Position flashing brackets over rafters
• Drill pilot holes at 15° angle
• Secure with 3/8" hex-head bolts

Roof Type	Bracket Spacing	Fastener Type
Asphalt Shingle	48-54 inches	Stainless Steel Lags
Metal Standing Seam	60-72 inches	Clamp-on Brackets

3. Rail Assembly

Attach rails perpendicular to roof slope:

• Use spirit level to ensure ±1° alignment
• Tighten mid-clamps to 20 Nm torque
• Leave 1/8" expansion gaps between rail sections

PV Module Installation Tips

• Maintain 0.5-1" clearance between panels and roof surface
• Use 4-point clamping system for wind resistance up to 140 mph
• Apply dielectric grease on MC4 connectors
