Electrical Safety

Critical Safety Rules

  • ⚠️ Always turn off power before connecting/disconnecting any components
  • ⚠️ Use GFCI outlets for all solar system connections
  • ⚠️ Never work in wet conditions or during rain
  • ⚠️ Check outlet grounding - use only properly grounded 3-prong outlets

Proper Wiring

  • Use UL-listed cables rated for outdoor use
  • Protect cables from weather and physical damage
  • Ensure all connections are secure and weatherproof
  • Follow manufacturer's wiring diagrams exactly

Mounting Safety

Weight Considerations

Ensure your balcony can support the system weight. Typical 800W system weighs 80-120 lbs.

Check: Balcony load capacity (usually 40-60 lbs/sq ft minimum)

Secure Mounting

Use proper mounting hardware designed for your balcony type. Ensure panels are securely fastened.

Important: Test mounting before full installation

Weather Protection

Wind Resistance

Panels must withstand wind loads. Use proper mounting brackets and ensure panels are angled to reduce wind resistance. In high-wind areas, consider professional installation.

Lightning Protection

While rare, lightning can damage systems. Consider surge protectors and proper grounding. Unplug system during severe storms if possible.

Q: Can I install solar panels myself?

A: Yes, for smaller systems (400W-600W) with proper knowledge. However, if you're not comfortable with electrical work, hire a professional. For 800W+ systems or complex installations, professional installation is recommended.
