Fanspex Solar Ventilation 2-Fan Kit 25W — IP67 Waterproof Solar Fan Kit for Chicken Coops & Greenhouses

The Fanspex Solar 2 Fan Kit is a weatherproof, battery-free solar ventilation system with two high-speed fans powered by a 25W panel to improve airflow in coops, greenhouses, sheds and pet houses.

This dual-fan kit delivers forced ventilation where wiring or mains power is impractical. Built to withstand outdoor conditions, the system runs directly from the included 25W solar panel (15.0 x 12.6 inches) and adjusts fan speed with available sunlight — no internal battery is included, so operation stops at night or when sunlight is insufficient. The package is designed for straightforward installation with a 16-foot cord and a mounting kit suited to common small-structure needs.

How much airflow and power does this solar fan kit provide?

The Fanspex kit combines two high-velocity fans powered by a single 25W panel. Each fan can reach speeds up to 3500 RPM and the system can move up to 360 CFM under good sunlight, giving meaningful ventilation for small enclosures.

• 25W solar panel (15.0 x 12.6 inches) provides daytime power.
• Two high-velocity fans with up to 3500 RPM for strong airflow.
• System airflow up to 360 CFM under optimal sun exposure.
• No battery — output varies directly with light intensity.

Is this fan kit suitable for outdoor and harsh weather?

Yes — the Fanspex system is built to tolerate outdoor elements. It has an IP67 waterproof rating and is rated to operate across a wide temperature range, so it withstands rain, snow, and a variety of climates without internal water ingress.

• IP67 waterproofing protects electronics from immersion and heavy rain.
• Operational temperature range from -13°F to 140°F (-25°C to 60°C).
• Durable materials and sealed connections for long-term outdoor use.
• Corrosion-resistant mounting components included in the kit.

How easy is installation and where can I mount it?

The kit is designed for simple mounting on small structures like chicken coops, greenhouses, sheds, and pet houses. A 16-foot cable and hardware are included so you can position the panel for best sun exposure while placing fans where airflow is needed most.

• Includes installation kit with brackets and screws for quick mounting.
• 16-foot cord gives flexibility in panel placement relative to fans.
• Panel size (15.0 x 12.6 in) fits on roofs, walls, or fence posts.
• Ideal for locations without grid power — no wiring to mains required.

What limitations should I expect with a battery-free system?

Because the Fanspex kit lacks a battery, fan speed tracks sunlight intensity and the system will not operate at night or during very cloudy conditions. For predictable 24/7 ventilation you would need an external battery or alternate power source, but for daytime cooling and airflow this system is efficient and low-maintenance.

• No included battery — stops working after sunset or in heavy rain.
• Performance reduces on overcast days or shaded installations.
• Best used for daytime ventilation or in combination with passive vents.
• Low-maintenance: fewer components and no battery replacement required.

Who is this for?

This Fanspex Solar 2 Fan Kit is well suited to hobby farmers, greenhouse growers, and homeowners who need daytime ventilation without running electrical wiring. It’s ideal for improving air exchange in chicken coops, pet houses, garden sheds, and small greenhouses where sunlight is available and a simple, durable, weatherproof solution is preferred. If you want stronger daytime airflow, easy installation, and an IP67-rated outdoor product without dealing with batteries or mains wiring, this kit is a practical choice.
