Kennedy Solar Attic Fans use solar panels with PERC (Passivated Emitter Rear Cell) technology which greatly improves solar cell efficiency. PERC panels have 2 additional layers to capture more photons/light at the rear of the panel. This results in an increased capture rate producing more electricity to power the fan. The panels are available in 4 sizes (32, 35, 48, or 65 wattages). The roof and curb mount adjustable panel models feature a pivoting bracket allowing the panel to be positioned to collect the most sunlight for optimal fan performance. Read more.

The Kennedy Solar Attic Fan housing is constructed of 1100 series, seamless commercial grade aluminum to prevent leaking. Because it is exposed to the harsh effects of the environment on a daily basis, Kennedy powder-coats the unit both inside and out for extra durability. Many of our competitors either paint only the outside or do not paint the unit at all. Also, many of our competitors use less durable materials to house their attic fans including polypropylene (plastic), sheet metal, or galvanized steel.

The flashing is responsible for preventing your roof from leaking. The Kennedy flashing is constructed of seamless, commercial grade aluminum and incorporates an angled throat to facilitate a Venturi or suction effect which increases cfm output and also reduces wear on the motor. Its round shape enables it to withstand the stresses of expansion and contraction due to temperature variations. Many of our competitors use lower-grade galvanized materials or even plastic. The flashing is powder coated inside and out for extra durability. Read more.

The Kennedy Solar Attic Fan utilizes a German engineered direct current motor. It is precision balanced to achieve low motor vibration and low motor noise. Additionally, the motor sits in an isolation bracket to further ensure a smooth, quiet operation. Each motor undergoes individual motor winding testing to ensure consistent motor performance and comes with a limited lifetime warranty.

Kennedy Solar Attic Fans incorporate a five-wing, precision balanced blade for the highest cfm output. The fan blades are manufactured using a non-corrosive aluminum to withstand all weather conditions. Many of our competition offer only 3 or 4 blades and some are even made of plastic.

The interior of a Kennedy Solar Attic Fan is protected by a stainless steel wire screen mesh. The screen keeps out debris, bugs, birds, and small rodents while allowing the air to freely exit the attic. Some of our competitors use lower-grade mesh such as plastic or steel that rusts over time.
