Solar Star, the solar-powered attic ventilation leader, brings you the most
technologically-advanced, environmentally-friendly solution today. Best
of all, Solar Star brings you the solution that costs nothing to operate.
Imagine the savings!
Most electric-powered attic ventilators are engaged by a thermostat, so they
only work when attic temperatures have already built up. Because of this,
thermostat activated units are forced to play catch up with built up heat.
Other systems may have a humidistat measuring the moisture level in
an attic. This too is a problem because when humidity levels reach the
preset activation level, condensation and moisture have already reached
a critical point.
The solution is Solar Star. Solar Star doesn’t have the costly problem of
replacing thermostats or humidistats like electric attic ventilators. And since
Solar Star functions from sunup to sundown, humidity and temperature
levels never reach those critical activation levels. Add in the fact that there is
NO electrical wiring; it is easy to see why Solar Star is the perfect solution.

Convert any ATTIC vent to a
solar-powered vent with our
Solar star Conversion Kit.
The Solar Star Conversion Kit can transform any vent into an eco-friendly
solar-powered vent. Now you can easily and quickly use the power of the
sun to reduce attic heat and battle moisture. No electrician, no electrical
hook ups, easy to install. Great for converting:

Install at your own risk!
Installation requires climbing and working at dangerous heights, including
on ladders, scaffolding, roofs and in attic spaces. Risk of death, personal
injury and property damage may result from a fall, or from falling objects.
Use extreme caution to minimize risk of accidental injury, including, but not
limited to the following procedures:
• Avoid working on surfaces that are slippery or wet.
• Use foot-wear with excellent traction.

• Use only strong, well supported ladders.
• Work only in calm dry weather.
A hot attic acts like a giant radiator, transferring heat into your living spaces
and sending both utility bills and temperatures soaring. In colder climates,
heat build-up in an attic causes snow to melt and run down where it freezes
at the eaves, which cause destructive ice damming. With Solar Star, you
can ventilate your attic, helping to equalize interior and exterior temperatures.
The result is a properly ventilated attic which prolongs your roof’s life, lowers
your utility costs, and makes your living environment more comfortable.
Solar Star:
• Reduces heat build up.
• Reduces air conditioning costs.
• Prolongs roof life.
• Prevents ice damming.
• When in an attic, ensure that your weight is supported at all times
with structurally sound framing; dry wall material is not designed to carry
a person’s weight.

Installation Tips
1. S olar Star products develop 100% of their operational power from the
sun; therefore it is very important that the solar panel be exposed to as
much sunlight as possible. The best location for the solar panel is on a
south-facing slope.
2. W hen using the Solar Star Conversion Kit, install the fan at the
highest vent on the roof for best results.
3. If the fan does not completely cover the vent opening it is installed
to, block any remaining areas of the vent opening to allow the fan
to draw air from lower intake vents. Ensure net free air opening is a
minimum of 1/150 of attic area or in compliance with local building
code requirements.
4. Install intake vents (not provided) low on the roof slope to create
continuous airflow through your attic. Soffit or eave vents are preferred.
Many of today’s houses have insufficient ventilation and air exchange. This
causes high humidity levels from everyday activities. This moisture migrates
through the ceiling towards the roof where it comes in contact with the cold
structure. Here ice and frost form causing damage to your roof structure.
Additionally, moisture can saturate insulation, reducing its functionality. Not
to mention that moisture in the attic can promote mold, fungal decay and
plywood delamination. Solar Star:
• Reduces moisture.
• Fights mold.
Note: Research has shown that for the highest level of effectiveness, Solar
Star products, matched with proper location and static intake vents, provide
balanced ventilation. Airflow will vary according to latitude as well as
atmospheric and climate conditions.
• Protects roof structure.
• Reduces heating costs.

• To reduce the risk of fire, electric shock, and personal injury; basic safety
precautions should always be followed when using electric tools,
including always wearing safety goggles or other suitable eye protection,
and ensuring work area is clear of all electrical wires, gas pipes, water
pipes, and other obstacles.
• When working in an attic, use of a mask or respirator is recommended to
avoid lung irritation. Attic spaces may be dark, confined, and subject to
extreme temperatures. Beware of sharp protruding objects. Do not attempt
installation without having someone within range of your voice or close
enough to come to your aid if necessary.
Step 1: Select Unit Location
Determine area to attach fan. Fan may be secured
to the studs of a gable vent, the roof deck
surrounding a powered vent, or framing adjacent
to a dormer vent or other passive attic vent that
is 16 in (405 mm) wide. Create wood framing for
vents without appropriate pre-existing framing or
decking material.

Step 2: Install the Fan
Secure fan with at least four (4) screws (provided) to the framing area with
motor facing the attic. If converting a power attic vent to solar-powered, for
best performance you should remove the existing fan and motor for maximum
air flow (and cap the electrical wire in the junction box).
Step 3: Mount Solar Panel
Mount solar panel to roof
within a 12 ft (3.5 m)
area of fan. Using the
four (4) 2 in (50 mm)
screws provided, secure
unit to composition roof
through the four corner

holes in the mounting
bracket. (For tile roofs, align and mark
the four corners of the solar panel with
the peaks of the curved tile. Drill four (4)
holes in the tile using a ¼” masonry
bit and insert the four anchors. Secure
to roof with four (4) 2 in screws through
the four corner holes. Insert two (2) 1”
spacers on the down slope portion of the
panel if needed.) Coat screw heads with
sealant (not provided). Route 15 ft (4.5 m)
power cable to fan.
