Quick Overview

The Solar Royal attic fan was developed, designed and engineered in the USA to address all the missing features and limitations within the current marketplace offerings.


Whether you’re trying to ventilate your attic, shed, boat dock, garage, barn, livestock pins, commercial spaces, etc… You have found the smartest solution for your solar powered ventilation needs.

If you have an attic fan, but don't have a solar attic fan, chances are you are not properly ventilating your attic and are spending more on cooling your home than you should be. That is because most electric attic fans stop working after only a few years and we don't even know it. When was the last time you were in your attic on a hot day and checked to make sure it was working? If you do check and see that it is not working, we strongly recommend replacing it with a solar attic fan that uses no electricity and lasts much longer than standard AC attic vent fans.

Benefits of a solar ventilation fan:

- Cools your home and spaces
- Exchanges air; changes passive ventilation to active ventilation
- Helps reduce HVAC costs and cooling cycles, also reducing the wear/tear and maintenance on your HVAC system
- Helps removes damaging moisture
- Makes your living space more comfortable
- Extends the life of your roof
- Qualifies for the 30% Federal Rebate program (unit & installation)
- Savings are even greater in hot southern climates and homes with poorly designed ventilation; can pay for itself in as little as one year of use!
