DELUMEE 8-Inch Solar Exhaust Fan — Dual 25W Panels, Install-Free Waterproof Vent for Greenhouse, Coop & Attic

The DELUMEE 8-inch solar exhaust fan is a compact, install-free ventilation system powered by two 25W solar panels designed to move air in greenhouses, pet houses, chicken coops and attics during daylight hours.

This unit combines a brushless DC motor fan and two monocrystalline 25W solar panels into a weatherproof package that requires no wiring or batteries. The panels include foldable supports so you can position them for optimal sun exposure, and the fan housing is built from durable ABS with a tempered-glass-covered solar face for impact protection. Because it’s solar-only, the fan runs when sunlight is available and is engineered to produce stronger airflow on sunny days while still operating in overcast conditions.

How much airflow can I expect from this 8-inch solar exhaust fan?

The DELUMEE fan uses a 12V brushless DC motor and is designed to move a meaningful volume of air for small-to-medium enclosures. Peak airflow occurs in full sun when both 25W panels deliver maximum output. On cloudy days the airflow is reduced but remains adequate for passive cooling and ventilation needs.

• Dual 25W monocrystalline panels provide higher daytime power delivery.
• Brushless DC motor offers steady RPMs and low operational noise.
• Optimized for small structures: greenhouses, coops, pet houses, attics.
• No battery means all sunlight is dedicated to producing airflow.

Do I need tools or mounting hardware to install the fan and panels?

No specialized tools or a fixed mount are required. The fan and panels are designed for install-free placement: the panels have foldable supports so you can set them at the right angle, and the fan housing is waterproof and ready to sit in or be fastened where needed.

• Fold-out supports on each panel let you angle for optimal sun exposure.
• Waterproof construction allows outdoor placement without extra sealing.
• Lightweight ABS fan casing avoids the sharp edges of metal frames.
• Optionally fasten the fan if a permanent installation is preferred.

How durable and quiet is the fan for long-term use?

The fan uses quality materials aimed at longevity and low noise. The A-grade monocrystalline cells and tempered glass protect the solar modules, while the brushless ball-bearing motor minimizes friction and noise. The manufacturer rates the motor for long service life under normal daytime operation.

• Tempered-glass-covered solar panels resist impacts and weathering.
• ABS plastic frame reduces corrosion risk and eliminates sharp edges.
• Brushless ball-bearing DC motor runs quietly and is rated for long life.
• Designed for daytime solar use—no nighttime operation without added battery.

Will this fan work in different weather and lighting conditions?

The dual-panel system boosts daytime performance and helps maintain airflow on overcast days, but this model does not include a battery. It performs best under direct sunlight and will produce reduced airflow during cloudy conditions; it will not run at night or during heavy rain if sunlight is insufficient.

• Two panels increase energy capture during variable light.
• Waterproof design tolerates outdoor exposure and light rain.
• No battery: continuous daytime operation but no night-time run time.
• Panels can be repositioned to capture reflected or angled sunlight.

Who is this for? The DELUMEE 8-inch solar exhaust fan is aimed at homeowners and hobby growers who want simple, low-maintenance ventilation without wiring or batteries. It suits greenhouse growers seeking daytime circulation, backyard chicken keepers improving coop airflow, pet-house owners needing passive cooling, and small attic spaces where daytime heat buildup is an issue. Choose this unit if you want a weather-resistant, easy-to-place solar ventilation solution that dedicates all daytime solar energy to moving air and reduces the need for electrical installations.
