☀️ How It Works

This kit runs on free, direct solar power. The included 100-watt panel drives the fan whenever sunlight hits it — the more sun, the stronger the airflow, up to 2,000 CFM at peak. Because it's solar-direct (no battery required), it's designed to ventilate during the day, exactly when heat and moisture build up most. Flip the built-in switch off any time you want to pause airflow.

❓ Frequently Asked Questions

How much air does it move?
Up to 2,000 CFM in full sun — enough to keep large spaces like garages, barns, and greenhouses well ventilated. Airflow scales with sunlight, so output is strongest in bright midday conditions.

Does the fan need electricity or an electrician?
No. It runs entirely on the included solar panel — no outlet, no wiring, no electrician, and nothing added to your power bill. Just mount the fan and panel, connect them, and you're set.

Does it run at night?
This is a solar-direct kit with no battery, so it runs while the panel is getting sunlight. That's by design — it ventilates during the hottest, most humid part of the day when you need it most.

What spaces is it best for?
Larger areas that need serious airflow — garages, greenhouses, barns, workshops, sheds, RVs, and off-grid cabins.

Is it hard to install?
Not at all. It's plug-and-play with included mounting hardware and instructions, and most setups take only a few minutes with basic tools.
