Safety Precautions

Solar panels generate DC electricity when exposed to light. Follow all safety guidelines.

  1. Install during low-light conditions or cover panel surface during wiring.
  2. Use insulated tools and wear appropriate PPE (gloves, safety glasses).
  3. Ensure mounting structure is stable and can withstand wind/snow loads.
  4. Do not step on or drop the panel; avoid mechanical stress.
  5. Do not disassemble or modify the junction box.

WARNING! DC voltage can cause electric shock or arc flash. Disconnect all circuits before working on system.

Specifications

Unpacking & Inspection

Upon receipt, inspect panel and contents carefully.

  1. Check packaging for damage; report any visible damage to carrier.
  2. Remove panel from packaging; avoid sharp objects.
  3. Inspect glass for cracks, cells for breaks, frame for deformation.
  4. Verify junction box is intact and sealed.
  5. Check included accessories: MC4 connectors (pair), mounting bolts/washers.

CAUTION! Handle with care; glass is tempered but can break under impact.

Mounting Installation

Mount panel on stable, load-bearing structure with proper orientation.

  1. Location: Select unobstructed area with maximum sunlight (south-facing in northern hemisphere).
  2. Angle: Adjust tilt angle based on latitude (typically 15-40 degrees).
  3. Mounting: Use corrosion-resistant bolts (M8 recommended) through pre-drilled holes.
  4. Spacing: Allow minimum 10mm clearance between panel back and mounting surface for ventilation.
  5. Grounding: Connect frame to grounding system per local electrical codes.

Tip: Use mounting rails or clamps compatible with panel frame dimensions.

Electrical Wiring

Connect panels in series or parallel to achieve desired voltage/current.

  1. Ensure all system components (charge controller, inverter) are OFF.
  2. Connect MC4 connectors: male to female, ensuring tight, waterproof seal.
  3. For series connection: Connect positive (+) of one panel to negative (-) of next.
  4. For parallel connection: Use branch connectors to combine positives and negatives separately.
  5. Route cables securely; protect from abrasion and UV exposure.
  6. Connect array output to charge controller or inverter input per manufacturer instructions.

WARNING! Do not exceed maximum system voltage. Use proper wire gauge for current.

Commissioning

After installation and wiring, verify system operation.

  1. Remove any covers from panel surface.
  2. Check all electrical connections are tight and secure.
  3. Turn ON charge controller or inverter.
  4. Measure open-circuit voltage at array terminals (should be near sum of panel Voc).
  5. Monitor charge controller display for incoming power.
  6. Verify no error indicators on system components.

Note: Output will vary with sunlight intensity and temperature.

Operation & Monitoring

Panel requires minimal operation intervention.

Tip: Output peaks around solar noon; seasonal variation is normal.

Maintenance

Regular maintenance ensures optimal performance and longevity.

  1. Cleaning: Use soft cloth or sponge with water; mild detergent if needed. Rinse with clean water.
  2. Frequency: Clean every 3-6 months, or as needed in dusty/pollen-heavy environments.
  3. Inspection: Annually check for:
    • Glass cracks or delamination
    • Frame corrosion or loose bolts
    • Junction box seal integrity
    • Connector condition (no melting, cracking)
    • Wiring insulation damage
  4. Tighten any loose mounting hardware.

CAUTION! Do not use abrasive materials or high-pressure spray. Do not walk on panel.

Troubleshooting

SymptomPossible CauseCorrective Action
No output / low powerShading, dirt, wiring faultCheck for obstructions; clean surface; verify connections and measure voltage/current.
Hot spot on panelCell mismatch, partial shadingRemove shading source; if persists, panel may be defective.
Junction box overheatingLoose connection, diode failureTurn off system; check tightness; contact service if diode issue suspected.
Water ingress in junction boxSeal failureDisconnect; dry thoroughly; reseal or replace junction box.
Frame corrosionEnvironmental exposureClean and apply protective coating if minor; consider replacement if structural.

Reset: For system issues, power cycle charge controller/inverter.

Warranty & Support

Select Solar warrants the 05002MG03 panel against defects in materials and workmanship for 10 years from date of purchase. Linear power output warranty: 90% of rated power at 10 years, 80% at 25 years. Warranty is void if panel is misapplied, modified, or improperly installed. For warranty claims or technical support:

Disposal: Recycle panel per local regulations; do not dispose in household waste.
