Runs off the grid
A 40 amp solar panel with mounting brackets powers the fan, so you don't need to run electricity to the greenhouse.


The MONT Solar Powered Ventilation System is designed to control the temperature in your greenhouse during the hot and cooler months. Most plants will not flower and fruit at temperatures over 85 degrees. To get them to flower temperature control is key.
Our commercial fan, exhaust louvers, and commercial thermostat are all made in the USA and our solar panel can produce more than 2 times the needed power to operate the fan at 100%, allowing for future options such as lighting and heating. The MONT Solar Ventilation System allows for off the grid operation, getting power to your greenhouse where you need it.
The system is easily retrofitted to other non- MONT greenhouses as well. The system can easily be set-up to run through a deep cycle marine battery to allow for power on demand , with or without the suns power.

* Disclaimers: Adaptations might be needed when installed in ANY greenhouse. This fan can be installed in a polycarbonate greenhouse. The polycarbonate panel will need to be cut to make sure the fan fits properly. If you decide to put it in a glass greenhouse, you won't be able to cut the glass because it will shatter. We recommend using a lexan panel to fill the gaps. This can be purchased in a local store.
