Before You Start
1. Check Local Requirements
- Building permits (required in most jurisdictions)
- Electrical permits (usually required for grid connection)
- HOA approval (if applicable)
- Utility interconnection agreement
2. Gather Tools & Materials
- Drill with appropriate bits
- Level and measuring tape
- Wrenches and screwdrivers
- Wire strippers and crimping tools
- MC4 connectors (if not pre-installed)
- Mounting brackets and hardware
- Safety equipment (gloves, safety glasses)
3. Choose Installation Location
- South, east, or west-facing balcony (avoid north)
- Minimal shading throughout the day
- Sturdy mounting surface (railing, wall, or ground)
- Accessible for maintenance
Step-by-Step Installation
Step 1: Install Mounting Brackets
Secure mounting brackets to your balcony railing, wall, or ground according to manufacturer instructions:
- Mark mounting points with a level
- Drill pilot holes (use appropriate anchors for wall mounting)
- Secure brackets with bolts or screws
- Verify brackets are level and secure
Step 2: Mount Solar Panels
Attach panels to mounting brackets:
- Lift panels carefully (they're heavy and fragile)
- Secure panels to brackets using provided hardware
- Ensure proper spacing between panels (for airflow)
- Set optimal tilt angle (20-30° for most locations)
Step 3: Connect Panels in Series or Parallel
Connect panels according to your inverter specifications:
- Series: Connect positive to negative (increases voltage)
- Parallel: Connect positive to positive, negative to negative (increases current)
- Use MC4 connectors (weatherproof)
- Route cables neatly and secure with cable ties
Step 4: Install Inverter
Mount inverter in a protected location (indoor or weatherproof enclosure):
- Choose location near electrical panel (if possible)
- Ensure adequate ventilation (inverters generate heat)
- Mount securely using provided hardware
- Keep away from direct sunlight and moisture
Step 5: Electrical Connection (⚠️ Professional Recommended)
Important: Many jurisdictions require a licensed electrician for the final grid connection. Even if DIY is allowed, consider hiring a professional for safety and code compliance.
If proceeding with DIY electrical work:
- Turn off main breaker before working
- Connect DC cables from panels to inverter
- Connect AC output to dedicated circuit breaker
- Use appropriate wire gauge (check local codes)
- Install disconnect switch (required in most areas)
- Ground the system properly
Step 6: System Testing & Inspection
- Check all connections are secure
- Verify inverter is receiving DC power
- Monitor inverter display for errors
- Schedule electrical inspection (required)
- Contact utility for final interconnection approval
Safety Tips
- Never work on live circuits: Always turn off power before electrical work
- Use proper PPE: Safety glasses, gloves, and non-conductive tools
- Weather conditions: Don't install during rain, snow, or high winds
- Panel handling: Panels are fragile - handle with care and use proper lifting techniques
- Electrical codes: Follow National Electrical Code (NEC) and local requirements
- Grounding: Properly ground all equipment to prevent electrical shock
When to Hire a Professional
Consider hiring a professional if:
- You're not comfortable with electrical work
- Local codes require licensed electrician
- Your utility requires professional installation
- You need to modify your electrical panel
- You're installing on a roof (higher risk)
- You want warranty protection from installer
