Turn sunshine into savings with Broan low profile
solar powered attic ventilators.
Surface Mount
For most roofs, our one piece SPAV is the perfect solution. Because
our solar cells are highly efficient at capturing the sun’s energy,
there is no need for unsightly raised panels or tracking systems.
Instead, what you see is a low profile ventilator in a contoured
design that integrates well with the roof.
Available in Black (345SOBK) and Weathered Wood (345SOWW).

Curb Mount
Identical in design to the Surface Mount unit but with an added
lip for flat, tiled, or unusually steep roof installations. A Curb Mount
installation requires the fabrication of a simple curb box frame
made from treated 2x4s to create a solid platform and better
manage water runoff.
Available in Black (345CSOBK) and Weathered Wood (345CSOWW).

Gable Mount
If roof mounting is not possible or desired, gable installation
provides the benefits of the SPAV with a remote-mounted, flat
solar panel positioned to best capture the sun’s energy, up to
50' away (15' of wire included). Finish the outside with a Broan
model 433 gable shutter.
Available in Black (345GOBK) and Weathered Wood (345GOWW).

Remote Mount
In some cases, installing the ventilator in a location that is
either less visible, more convenient to reach from the roof-side,
or more accessible from the attic-side, is desirable. Remote
mount enables the ventilator to be installed independent of the
solar panel, up to 50' away (15' of wire included). Locate the
remote, flat panel to receive the best sunlight exposure and
hide the ventilator from view.
Available in Black (345RSOBK) and Weathered Wood (345RSOWW).

Attic Ventilation 101
The purpose of ventilating your attic is to equalize
temperatures inside with those outside the attic to
prevent the build-up of heat and moisture. Without
adequate ventilation, air inside your attic can reach
150°F or more during the summer, warming your living
area, increasing the load on your air conditioner, and
adding to your energy bill. In the winter, ice dams can
result from poor ventilation, and moist air from inside
the home can condense on attic surfaces causing mildew,
rotting wood and wet insulation if not properly
ventilated. Year round ventilating of your attic minimizes
harmful moisture in the winter and lowers the
temperature of your home in the summer. Keeping your
attic cool and dry can extend the life of your roof, by
preventing rot, premature aging, and damaging shingle
distortion that can result from excessive heat. A cool
attic in summer also saves you money on your energy bill
and extends the life of your
air conditioner.
Solar Power Savings
Broan Solar Powered Attic
Ventilators use energy from
the sun to operate and require
no additional electricity, which
means you save up to $180 per
year that you might pay to operate
an electric powered attic ventilator,
depending on your local electric rates, size of attic,
climate, etc... Plus, you can save even more with
a 30% Federal Tax Credit on both the purchase
price and installation costs of your Solar Powered
Attic Ventilator. *
Green All Around
Broan Solar Powered Attic Ventilators operate without
fuel, waste, or pollution, and earn points towards Green
building. So you can save money on electricity without
using any to do it, which is green for the environment,
and some extra green for your wallet.
How Much Ventilation Do You Need?
Effective attic ventilation requires air to exit at
or near the peak of the roof and replacement air to be
drawn in under the eaves of the house, via soffit venting.
The Home Ventilating Institute (HVI) recommends that
powered attic ventilators provide at least 10 air changes
per hour to equalize attic temperature. Below are
instructions on how to determine the recommended
ventilation needs for your attic.
1) Calculate the volume of your attic, in cubic feet,
depending on the style of your home’s roof.
Attic Volume for Gable Roof
Volume = Length x Width x Height x 1/2
Attic Volume for Hip Roof
Volume = Length x Width x Height x 1/3
2) Attic Volume x 10 Air Changes per Hour =
Total Cubic Feet per Hour of
ventilation recommended.
3) Total Cubic Feet per Hour ÷ 60 Minutes/Hour =
Cubic Feet Per Minute (CFM) of Ventilation
Recommended.
Example: Average Gable Attic Volume =
58.75' x 29' x 7.25' x ½ = 6,176 Cubic Feet
6,176 Cubic Feet x 10 Air Changes/Hour =
61,760 Cubic Feet/Hour ÷ 60 Min./Hour =
1,029 CFM
4) Replacement air is drawn through vents in
your soffit. To determine the minimum soffit
vent area required (in square inches) multiply
the total CFM of your powered ventilator(s)
by 0.48. This number is the total square
inches of soffit venting required by your
powered ventilator(s).
Example: 1,029 CFM x 0.48 = 494 Square
Inches of soffit vent area recommended.
Solar Panel Integrated, low profile, 28-watt Solar Panel efficiently captures
sunlight from dawn to dusk without the unsightly props or pivoting stands used
by some manufacturers. Rugged, tempered glass withstands large hail and
resists delaminating.
Housing Attractive, low profile, molded design, of UV-stabilized, color-dyed,
rugged ABS plastic withstands impact from hail and resists fading. May also be
painted to match roof color for installation flexibility.
Optional Thermostat Easy to install, this optional accessory disables the
motor below 50° for climates where cold-weather condensation isn’t a concern and
to extend motor life. The thermostat activates the motor at temperatures above 61°
to vent air from dawn through dusk.
Motor Direct-current, variable voltage motor is dynamically balanced
for superior performance and silent operation.
Fan 12” Diameter, one-piece aluminum 5-blade fan pitched for
maximum air flow.
Hardware Stainless steel fasteners secure galvanized steel brackets
and aluminum, heavy gauge screen for durability and corrosion resistance.
Screen keeps out insects, animals, and birds without impeding airflow.
