4. Components
The OmniPV Solar-Powered Roof Fan package includes the following items:
- 1 x Fan Body with Flexible Flashing
- 1 x Solar Panel
- 1 x AC Adaptor (for continuous operation or low sunlight conditions)
- 2 x Rafter/Batten Straps
- 4 x Tech Screws
5. Installation
Proper installation is crucial for the fan's performance and longevity. It is recommended to have a qualified professional perform the installation.
5.1 Site Selection
Choose a location on the roof that receives maximum direct sunlight throughout the day. Ensure adequate clearance around the fan for proper airflow and maintenance.
Figure 4: Versatile installation options for various structures.
5.2 Installation Steps (General Guidelines)
- Prepare the Opening: Create a circular opening in the roof according to the fan's dimensions (approximately 12 inches diameter for the fan body). For tile roofs, one roof tile may need to be removed.
- Position the Fan: Place the fan body with its flexible flashing over the opening. Ensure the flashing is properly seated and conforms to the roof surface.
- Secure the Fan: Use the provided tech screws to secure the flashing to the roof deck. Apply a suitable roofing sealant around the edges of the flashing to prevent water intrusion.
- Install Solar Panel: Attach the solar panel to the fan body using the provided brackets. Adjust the angle of the solar panel for optimal sun exposure.
- Connect Wiring: Connect the solar panel wiring to the fan motor. If using the AC adapter for continuous operation, connect it to the designated port on the fan and plug it into a 110V power source.
- Internal Bracing (Optional): Use the rafter/batten straps to secure the fan body to attic rafters for additional stability, if necessary.
Note: Detailed installation instructions may vary based on roof type. Consult a roofing professional for specific guidance.
6. Operation
The OmniPV Solar-Powered Roof Fan operates automatically based on sunlight and temperature conditions.
6.1 Automatic Operation (Solar Power with Thermostat)
When the AC adapter is disconnected, the fan operates solely on solar power. The built-in thermostat controls its activation:
- The fan will turn on when the attic temperature exceeds 77°F (26°C).
- The fan will turn off when the attic temperature falls below 77°F (26°C).
6.2 Continuous Operation (AC Power)
To ensure continuous operation regardless of sunlight or temperature, connect the provided 110V Smart Adapter to the fan and a power outlet. In this mode, the fan will run continuously as long as the AC adapter is connected and powered.

7. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your solar roof fan.
- Solar Panel Cleaning: Periodically clean the surface of the solar panel with a soft, damp cloth to remove dust, dirt, or debris that may reduce efficiency. Do not use abrasive cleaners.
- Fan Blade Inspection: Annually inspect the fan blades for any obstructions, damage, or excessive dust buildup. Carefully clean if necessary, ensuring power is disconnected.
- Structural Check: Periodically inspect the fan's mounting and flashing for any signs of wear, damage, or potential leaks. Reapply sealant if needed.
- Wiring Inspection: Check all wiring connections for tightness and signs of wear or damage.
8. Troubleshooting
If you encounter issues with your OmniPV Solar-Powered Roof Fan, refer to the following table:
| Problem | Possible Cause | Solution |
|---|---|---|
