4. Setup and Installation
Installation of the DAH Solar Module requires careful planning and adherence to safety guidelines. It is strongly recommended that installation be performed by certified solar professionals.
4.1 Pre-Installation Checklist
- Verify all components are present and undamaged.
- Ensure the mounting structure is robust enough to support the module's weight (22 kg) and withstand local wind (2,400 PA rear load) and snow loads (5,400 PA front load).
- Confirm compatibility with your chosen micro, hybrid, or standard inverter.
- Have all necessary tools and safety equipment ready.
- Review local building codes and electrical regulations.
4.2 Installation Steps (General Guidelines)
- Mounting Structure Preparation: Install the solar module mounting rails securely on the roof or desired surface according to the manufacturer's instructions and local building codes. Ensure proper spacing and alignment.
- Module Placement: Carefully lift and place the solar modules onto the mounting rails. Secure them using appropriate clamps or fasteners. Ensure even pressure distribution to avoid stressing the module frame.
- Electrical Connections:
- Connect the MC4-compatible cables from the solar module's junction box to the input of your inverter or charge controller.
- Ensure correct polarity (+ to + and - to -).
- For series connections, connect the positive terminal of one module to the negative terminal of the next. Up to 33 modules can be connected in series.
- For parallel connections, connect positive terminals together and negative terminals together. An unlimited number of modules can be connected in parallel.
- Ensure all connections are tight and secure to prevent arcing and power loss.
- Grounding: Properly ground the solar module frame and mounting system according to local electrical codes to prevent electrical shock hazards.
- Inverter Connection: Connect the output of the inverter to your electrical system or grid, following the inverter manufacturer's instructions and local regulations.
- System Testing: After all connections are made, perform a thorough system test to ensure proper operation and power output.
5. Operating the Solar Module
The DAH Solar Module operates automatically when exposed to sunlight, converting solar energy into DC electricity. This DC electricity is then converted into usable AC electricity by your connected inverter.
- Sunlight Exposure: Ensure the module is exposed to direct sunlight for maximum power generation. Shading from trees, buildings, or other obstructions will reduce output.
- Monitoring: Monitor your inverter's display or associated monitoring system to track power generation and system performance.
- Bypass Diodes: The integrated 3 bypass diodes help maintain optimal current flow and prevent hot spots in case of partial shading, ensuring continuous power output.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your DAH Solar Module. Thanks to its Full Screen technology, cleaning requirements are significantly reduced.
- Cleaning:
- Periodically inspect the module surface for dirt, dust, leaves, or other debris.
- The patented Full Screen technology allows rainwater to naturally wash away most impurities.
- If manual cleaning is necessary, use a soft cloth or sponge with clean water. Avoid abrasive materials or harsh chemicals.
- Clean during cooler parts of the day (early morning or late afternoon) to prevent thermal shock to the glass.
- Visual Inspection:
- Regularly check for any visible damage to the glass, frame, cables, or junction box.
- Look for signs of corrosion, discoloration, or loose connections.
- Ensure mounting hardware remains secure.
- Professional Inspection: It is recommended to have a qualified solar professional inspect your system annually to ensure all components are functioning correctly and safely.
7. Troubleshooting
If you experience issues with your solar module, refer to the table below for common problems and solutions. For complex issues, contact a qualified professional.
| Problem | Possible Cause | Solution |
|---|---|---|
| Low Power Output | Partial shading on the module. Accumulation of dirt/debris. Faulty inverter. Loose electrical connections. | Remove any shading obstructions. Clean the module surface. Check inverter status and error codes. Inspect and secure all electrical connections. |
| No Power Output | Inverter off or faulty. Disconnected cables. Grid outage. | Check inverter power and error indicators. Verify all cables are securely connected. Confirm grid status. Contact professional if issue persists. |
| Visible Damage to Module | Physical impact (e.g., hail, falling debris). | Do not attempt to repair. Isolate the damaged module from the system. Contact a qualified professional for assessment and replacement. |
| Overheating (Hot Spots) | Sustained partial shading. Defective cell or bypass diode. | Ensure no persistent shading. While bypass diodes mitigate this, persistent issues require professional inspection. |
