MARBERO Solar Powered Fan Kit 15W with Two 4.7" Waterproof Fans — 13 ft Cable, Outdoor Ventilation for Coops & Greenhouses

The MARBERO 4.7-inch Solar Powered Fan Kit is a 15W monocrystalline panel with two waterproof brushless fans and a 13-foot cable, built to ventilate small outdoor enclosures like chicken coops, greenhouses, and pet houses without wiring or batteries.

This kit pairs a high-efficiency 15W solar panel with two compact 4.7-inch intake/exhaust fans to move air where it’s needed using only sunlight. It’s designed for easy DIY mounting and flexible configurations—both fans can be used together for extra exhaust, both as intakes, or one as intake and one as exhaust. The system is ruggedized with aluminum housings, double metal guards, and a waterproof motor to hold up in outdoor conditions.

How will this fan kit improve ventilation in my chicken coop or greenhouse?

The MARBERO kit increases airflow to remove heat, dust and stale air without electricity. Because the panel directly powers the fans, ventilation scales with sun intensity and provides peak cooling during the hottest daylight hours when it’s most needed.

• 15W solar panel supplies power during sunny conditions for continuous daytime ventilation.
• Two 4.7" fans reach up to 2,500 RPM for stronger airflow than single-fan kits.
• Use fans as intake, exhaust, or mixed setup to create controlled cross-ventilation.

Can I install this kit myself and how long are the cables?

Yes—this kit is built for straightforward DIY installation and includes mounting plates, screws and zip ties. The panel has a 9.8 ft main cable while each fan adds 3.2 ft; when connected the total reach is about 13 ft for flexible placement.

• 9.8 ft panel cable and two 3.2 ft fan cables for up to 13 ft total run.
• All mounting hardware included for panel and fan attachment to wood or vents.
• Lightweight components simplify drilling and positioning without professional help.

What happens in cloudy weather or at night—does it include a battery?

This solar fan kit does not include a battery backup; fan operation depends entirely on sunlight. On overcast days or when the panel is shaded the fans will run slower or stop, and they will not operate at night or during heavy rain.

• No built-in battery—daytime sunlight required for fan operation.
• Performance drops in shade or cloudy conditions; position panel at ~45° angled to maximize output.
• Optional: compatible with external battery controllers if continuous power is needed (sold separately).

Who is this kit best suited for? The MARBERO solar fan kit is ideal for homeowners and small-scale keepers who need a low-maintenance ventilation solution for outbuildings where running AC power is inconvenient or costly. It’s a good match for backyard chicken coops, small greenhouses, sheds, dog and pet houses, attic vents and remote camping shelters—anywhere daytime-only airflow driven by sunlight improves air quality and animal comfort. If you require 24/7 ventilation or guaranteed operation during storms and nights, consider adding a separate battery or controller to the system.
