Solar DC Cooling, Fans & Kits

small DC & Solar Fans

Fans are nearly ideal solar powered loads. They can run directly off DC, (as with all of the following products). Solar powered fans run when they are needed the most - when the sun is shining.

Attic venting is an important aspect in maintaining the functions in your home. Proper venting cools your roof extending the material life and reduces the load on your air conditioning system. Attic venting also increases fresh air circulation which reduces vapor build up generated by everyday activities like showering and cooking. Excess moisture trapped in your attic can cause a variety of problems from rust to rot to incresed bacteria and mold counts which can have a direct impact on your respiratory health! Passive vents have been a part of building codes for years but to really get the benefit of venting, soffit vents, ridges vents and louvers rely on nature to provide sufficient air pressure and air movement. So the majority of the time your attic is stagnant and continues to build up heat and moisture.

Use the sun's energy for years of worry-free, no-cost cooling & air circulation.

Solar Fans
During summer months, your attic temperatures can reach 150�F. High temperatures cause an increase in temperature in the living space and an increase in energy consumption by air conditioning equipment. Forced ventilation will circulate cooler air through the attic space and lower the temperature. Fan and solar module combinations allow daytime ventilation and air circulation anywhere the sun shines. They are great for greenhouses, kennels, barns and attics where AC power is not available. The solar module runs the fan at full power in full sun and at a slower speed in overcast weather. Operation is automatic. When the sun shines on the solar module, the fan begins to operate. The 12” and 16” solar fan kits include fan, solar module and 10’ of two conductor wire.

Solar Powered Fan Kits
These kits include our venturi fan, a solar module, mounting hardware and 10’ of wire. The fan can deliver 550-1000 CFM when the module is in full sun. The reversible, ball bearing PM motor allows the fan to be used for intake or exhaust by reversing the wire at the motor. The fan is the Venturi fan from below. Add a three way switch to turn the fan off or reverse direction. Add another 10 watt module for $120 to increase the flow.

Solar Attic Fan

This fan is the best made attic fan we've found. It is watertight and constructed from powder coated 14 gauge aluminum with a stainless steel screen and hardware. Designed for high airflow, the seamless shroud keeps the air moving efficiently by utilizing the principle of the venturi effect and cools the solar module for best output. Comes with 50 year neutral cure silicone to bond the flashing to the roof. WARRANTY: Solar Attic Fan is the best solar attic fan you can buy and is backed by the best warranty in the industry; 25 year warranty on the housing, 10 year warranty on the solar panel and 5 year warranty on the motor. Made in the USA.

Let's not forget its powerful!

Operating at 850CFM, a single unit can fully vent up to 1200 square feet. These attic fans are available with a flush mount solar module (standard) or with a tiltable mount solar module. The solar module can then be tilted up on its tiltable mount or mounted remotely allowing for optimal panel placement.

Venturi Fans
These fans have an aluminum 3 wing blade mounted in a fabricated square steel ring frame style venturi for easy mounting. They can be used on existing battery systems or with other module combinations with up to 30 VDC. The 12” fan fits between 16” on center studs and delivers approximately 500 CFM at 12 volts and 1200 CFM at 24 volts. The 16” fan fits between 24” on center studs and delivers 750 CFM at 12 volts and 1800 CFM at 24 volts.

Ceiling Fan
This hanging ceiling fan runs on a 12 or 24 volt battery system. They move a lot of air at 24 volts and are great in large rooms with vaulted ceilings. A speed control is recommended so that you can adjust how fast they run. At 12 volts they move less air and work great for fairly low ceilings, but are slightly under-powered in large rooms with vaulted ceilings. The step-up control below gives you variable voltage, from 0 to 20, from a 12 volt input and make the fan perfect for any situation. These fans have simulated wood grain blades that can be painted and a black molded body. (Fan comes with blade painting instructions.) They can be configured with 4 or 5 blades and installed close mount (as pictured) or with a “downrod” to distance the fan from the ceiling. With the downrod connected, the motor hangs approximately 8 inches from the ceiling. Current draw is 0.5 amps at 12 V and approximately 1.5 amps at 24 V. All hardware included. Made in USA. 1 year warranty; 90 day warranty on motor.

Fan Speed Control with Reversing Switch
These variable speed controls work well with all of the fans on this page, or for controlling any 12 or 24 volt permanent magnet motor with a current draw of 1.5 amps or less. The 12 volt version increases the voltage to allow three times the air movement by the fan than you would get running it directly on 12 volts. The center position of the switch is off. Pushing the switch to either side turns the fan on, but one way makes the motor turn clockwise and the other way makes the motor turn counterclockwise. Filtering in the circuitry keeps audio noise to a minimum. The 12 volt voltage increaser is in a double-gang wall plate.

Evaporative Cooler
The evaporative cooler below works well in climates with very low humidity. Air is cooled when it blows through a wet medium because the moving dry air causes the water to evaporate, or change from a liquid to a gas. When water changes from liquid to gas, it removes heat, causing a cooling effect. Evaporative coolers work best when humidity is under 30%. They will not work if the humidity is over 50%.

SolarCool DC Evaporative Cooler

Let the sun cool your home or office with the super efficient solar powered SolarCool DC Evaporative Cooler-- supplying comfort without the operational cost.

Super efficient evaporative cooler delivers cold air direct from a 40 watt solar module during peak daylight hours. For longer daytime operation, we suggest using a 75 watt module and a linear current booster as in our solar kit below. Designed especially for smaller one or two room homes or trailers this side draft unit will exchange the room air every 5 minutes in 600 square feet of living area.

The SolarCool removes dust, pollen, and air pollution, requires no maintence, is quiet, lightweight (35 lbs), and easy to install. Its performance is rated at 1000 CFM, PV direct at 2.2 amps. Consumes less than 1 gallon of water per hour. It features 3456 cubic inches of honeycomb evaportive pad media, chemically treated to resist hard water deposits, that lasts 5 seasons before replacement. It is completely assembled and is constructed of galvanized steel with tan power coated paint. Unit features a long-life 24 volt DC fan motor and water pump, protective fan outlet grill, brass float valve and wiring junction box. Additonal PV modules will extend the peak daytime operation. For extended cooling beyond daylight, the SolarCool can operated direct from a 24 volt DC battery as well, producing nearly 1400 CFM at 24VDC, 3.3A operation. 6 month warranty.

Solar Kit for SolarCool Evaporative Cooler
Using a 75 watt solar module and a linear current booster with the evaporative cooler above, you can produce cool air even when the sun is not directly overhead. It runs only when the sun is shining, just when you usually need cooling. When the morning sun strikes the solar module, the cooler begins to run at low speed. As the sun reaches noon, the output of the solar module increases and so does the cooling. The Linear Current Booster matches the output of the solar module to the optimum voltage and current required by the motor in the cooler. It even allows the cooler to run at very low speed in cloudy weather. This kit includes a 75 watt solar module, 20 feet of wire and a Linear Current Booster. Order cooler above separately.

Heating and Cooling Thermostats
These thermostats can switch up to 22 amps at 120 VAC and they work fine for up to 10 amps at 12 or 24 VDC. Use them with DC fans to turn the fans on or off as temperature changes. They mount in a standard 2” x 4” electrical box. The Attic Fan Thermostat has single pole contacts that close (turn fan on) as temperature rises. Its adjustment range is 90�F to 130�F. When the thermostat reaches the turn-on temperature, it must fall by 15�F before it will turn off. The Heat/Cool Thermostat has double throw contacts, so it can be used to turn a fan on as the temperature rises or as it falls, depending on how it is wired. Its range is 50�F to 90�F and its differential is 2�F.
