Cool your greenhouse, no electrician required.

If you’re building a DIY greenhouse and want a ventilation system that works without tying into household power, the Snap Fan Solar Exhaust System is your go-to solution. This all-in-one solar-powered exhaust fan kit is designed to pull heat out of your greenhouse as the sun shines, keeping your space cooler when your plants need it most.

Each kit includes a high-efficiency Snap Fan with matching solar panel, a thermostat and wiring harness kit to automate airflow based on temperature, and a passive aluminum shutter to protect the fan opening when not in use. Whether you’re working with a small starter greenhouse or a full-sized backyard setup, we offer three fan sizes to suit your space.

Fan Size CFM Panel Wattage Greenhouse Size Range
12" 810 50W 6' x 8' to 8' x 12'
16" 1310 50W 8' x 16' to 10' x 16'
20" 2200 100W 12' x 16' to 14' x 20'

This is the same system featured in Epic Gardening’s DIY Greenhouse Build, where it helped power off-grid greenhouse ventilation. Jacques and the team paired the 20" Snap Fan kit with our Heavy-Duty Aluminum Shutters and Solar Shutter Control Kit with Liberty Auto Opener to create a fully automated, electricity-free airflow system.
