Solar Greenhouse Exhaust Fan With 100 Watt Panel

1827-AG Solar Greenhouse Exhaust Fan With 100W Panel

Professional-Grade Greenhouse Ventilation With Ultra-Low Power Usage

This item is currently on Pre Order

The Western Harmonics 1827-AG is a 20-inch louvered exhaust fan engineered for home greenhouses, commercial growers, and high-tunnel operations. Built with a galvanized steel housing, wind-driven louvers, and a high-velocity 18-inch metal blade, this system delivers powerful air exchange while running on safe, efficient 12-volt DC power.

Whether you power it from the grid, the included 100W solar panel, or a portable power station, the 1827-AG provides reliable, high-volume ventilation while using one-third the energy of a traditional 120V greenhouse exhaust fan.

Why Greenhouses Need This Fan

1. Home Greenhouses

Home growers battle heat buildup, humidity spikes, and stagnant air pockets. This fan solves all three with:

3,300 CFM of high-velocity airflow

Automatic wind-driven louvers that open with airflow

Zero-cost solar operation during peak heat hours

Safe low-voltage power around misting systems and moisture

It stabilizes temperature and humidity without increasing your electric bill.

2. Commercial Greenhouses (multi-bay, propagation houses, retail houses)

Commercial growers need:

consistent airflow

low operating costs

safe equipment around irrigation

long daily runtimes

scalable systems

The 1827-AG delivers:

⅓ the power usage of 120V exhaust fans

Cooler motor temperatures for long runtimes

Low-voltage safety around wet floors and metal frames

Solar compatibility to reduce operational overhead

MC4 connectors for fast, modular installation

This is agricultural-grade equipment — not hobby-grade plastic.

3. High Tunnels & Hoop Houses

High tunnels trap heat fast. Growers need strong directional airflow and low-cost continuous ventilation for small high tunnels and hoop houses.

The 1827-AG excels because:

It can run directly from the included 100W solar panel

It uses only 60–70 watts when grid-powered

It moves 3,300 CFM, ideal for long tunnel structures

It’s metal-built, not plastic

It’s safe around drip irrigation, misters, and condensation

This is one of the few fans that works equally well in off-grid, semi-grid, and full-grid greenhouse operations.

Three Ways to Power the 1827-AG

1. Plug Into the Grid (AC Adapter Optional)

Using a standard 12V 8A power supply, the fan becomes a super-efficient grid-powered exhaust system.

Uses only 60–70 watts

Costs up to 66% less to operate than 120V fans

Runs cooler and quieter

Perfect for long daily runtimes

2. Run Directly From the Included 100W Solar Panel

The included 100W panel powers the fan at zero cost in full sunlight.

Ideal for:

small high tunnels

remote greenhouses

off-grid homesteads

power-outage protection

Solar + 12V DC = free airflow during the hottest hours of the day.

3. Use a Portable Power Station

Compatible with most 12V DC outputs (Jackery, EcoFlow, Bluetti, etc.).

Perfect for:

mobile greenhouses

seasonal structures

temporary grow setups

emergency ventilation

Low-Voltage Safety Advantage

Greenhouses are wet, humid, and metal-framed — the worst environment for 120V AC fans.

The 1827-AG runs on 12V DC, which means:

reduced shock risk

safer around irrigation and misting

no high-voltage wiring

safer for workers and animals

ideal for metal structures

This is why low-voltage systems are the standard in agricultural environments.
