Can You Use a Solar Attic Fan for Greenhouses?

Are you thinking about building a greenhouse or improving your current greenhouse? Perhaps you’re doing some research on how to maintain your greenhouse and optimize ventilation. As you know, keeping your greenhouse ventilated and maintaining the inside temperature is vital to ensuring your plants grow strong and healthy.

There are many options when it comes to ventilating your greenhouse and some are better than others. You could go with passive ventilation methods, i.e. cracking a window and crossing your fingers. Though we love an easy fix to our problems, passive ventilation is unreliable and may not be enough.

When it comes to choosing active ventilation methods, you’re basically looking at incorporating one or more fans into your greenhouse. What if you could incorporate a solar attic fan into your greenhouse? Is that possible? The short answer is yes. Below, we’ll tell you how it works and why it’s such a great option.

How Do Solar Attic Fans Work?
Solar attic fans are typically installed on the roof above an attic to ventilate the attic space. They use photovoltaic (PV) panels to harness the energy of the sunlight and use that energy to power the attic fan itself.

Non-solar attic fans already reduce energy bills and cut down on wasted energy by reducing attic temperatures and not forcing your AC to fight a hot attic. Solar attic fans go a step further. During the day when the sun is shining, they operate totally on solar power from the sun. When the sun goes down, these attic fans switch to electric power to keep the attic at an optimal temperature.

Luckily, solar attic fans can be used in just the same way for greenhouses as they are for attics.

Using a Solar Attic Fan for Your Greenhouse
Using a solar attic fan for your greenhouse is an awesome way to ventilate your greenhouse in an eco-friendly way. As the sun feeds the plants in your greenhouse, heating up the air inside your greenhouse, it will also power up the solar attic fan as temperatures rise.

The 14” Solar Attic Fan 40 W Panel, which you can order through us here at will automatically switch on at 88 degrees and switch off at 77 degrees, ensuring your plants never overheat. Plus, nobody likes to work in a super hot greenhouse — it’s uncomfortable and even dangerous.

This solar attic fan won’t just keep your plants happy, but you too!

Solar attic fans also require no maintenance, so once you install it, you can just let it be.
