Installation

Unpack and inspect contents. Ensure all components are present and undamaged.

Mounting: Use provided clamps or bolts to secure panel to mounting structure (roof or ground).
Orientation: Install facing true south (Northern Hemisphere) at optimal tilt angle for location.
Spacing: Allow minimum 10mm between panels for thermal expansion and ventilation.
Grounding: Connect frame to grounding system using provided grounding lug.

WARNING! Panel is heavy and fragile; use proper lifting techniques and PPE. Do not step on panel. Install only in suitable weather conditions.

First-Time Setup

After mechanical installation, proceed with electrical connections.

Series/Parallel Connection: Plan array configuration to match inverter input voltage and current.
Connect Panels: Use MC4 connectors to link panels in planned configuration.
Connect to Inverter: Route final positive and negative cables to inverter DC inputs.
System Check: Verify all connections are tight and polarity is correct before powering.

CAUTION! Solar panels generate DC voltage whenever exposed to light. Cover panels with opaque material during connection work.

Controls and Monitoring

Panel has no active controls. Performance is monitored via the connected inverter or external monitoring system.

Inverter Interface: Check inverter display for DC voltage, current, and power.

Monitoring Systems: Many inverters offer Wi-Fi/ethernet connectivity for remote monitoring via app or web portal. Key metrics: real-time power, daily/weekly/monthly yield, system efficiency.

Visual Inspection: Regularly check for physical damage, soiling, or hot spots (using thermal camera if available).

Connecting to System

Electrical connection to inverter or charge controller.

Ensure all system components (inverter, disconnects) are OFF.
Connect panel strings using MC4 connectors (click to confirm lock).
Route cables through conduit if required by local code.
Connect final DC cables to inverter/charge controller, observing correct polarity (+ to +, - to -).
Secure all cable management.

Tip: Use a multimeter to verify open-circuit voltage of the string before connecting to inverter.

Performance Optimization

Maximize energy yield through proper installation and maintenance.

Tilt Angle: Set tilt equal to local latitude for year-round average optimal yield.
Shading: Avoid shading from trees, chimneys, or other panels. Even partial shading significantly reduces output.
Cleaning: Clean glass surface periodically with water and soft cloth to remove dust, pollen, bird droppings.
Ventilation: Ensure rear of array has airflow to keep operating temperature lower.
Inspection: Check for micro-cracks, cell discoloration, or junction box issues annually.

WARNING! Do not use abrasive materials or harsh chemicals for cleaning. Do not spray cold water on hot panels.

Safety Features

Bypass Diodes: Integrated in junction box to minimize power loss if cells are shaded or damaged. Overvoltage Protection: Provided by inverter/charge controller. Frame Grounding: Dedicated lug for safe grounding connection.

Care & Maintenance

Unplug system or turn off DC disconnect before any maintenance. Inspect visually every 6 months. Clean glass 2-4 times per year depending on environment. Check electrical connections annually for tightness and corrosion.

CAUTION! Never disconnect under load. Always follow lock-out/tag-out procedures.

Troubleshooting

Symptom	Possible Cause	Corrective Action
No output from panel	Shading, damaged cells, faulty connection	Check for shading; inspect for physical damage; verify MC4 connections are secure.
Low power output	Soiling, mismatch in string, high temperature	Clean panel surface; check all panels in string are same model/orientation; ensure ventilation.
Hot spot on panel	Bypass diode failure, cell damage	Contact qualified technician for junction box inspection/repair.
Water ingress in junction box	Seal failure	Disconnect panel, replace junction box or entire panel.
Frame corrosion	Harsh environment	Inspect mounting hardware; ensure proper grounding; consult installer.

Reset: Not applicable. For electrical system reset, refer to inverter manual.
