Universal Fit Solar Powered Attic Venting System


Why a Solar Attic Vent?

Passive vents don’t provide active air movement. Turbines are only effective on windy days. So the majority of the time your attic is stagnant and continues to build up heat and moisture. The Nature’s Power Solar Attic Vent provides optimum ventilation on those hot breezeless days when you need it the most!


Clear the air. Quickly.

The Nature's Power Solar Attic Vent provides a simple solution to many problems that can occur in your attic space. The fan in the Solar Attic Vent can successfully vent up to 1,000 square feet, operating up to 400 CFM in full sunlight. By quickly venting hot air and moisture out of your attic space, the Solar Attic Vent cools the roof and reduces extreme attic temperature, prolonging the life of your roof by reducing vapour build-up and preventing rust, rot, bacteria and mould. So whether it's summer or winter, the Nature's Power Solar Attic Vent is continually protecting your attic space and prolonging the lifetime of your roof.

You can take it to the bank.

Wouldn't it be amazing to actually be able to save on the cost of air conditioning in summer and the cost of repairs due to moisture? Because the Nature's Power Solar Attic Vent is so efficient, it will help you save on your air conditioning costs by 10% to 50% during the summer months and will help move moisture out of your attic space during the winter months, reducing damage caused by mould and moisture and reducing repair costs. And because it is solar-powered, the Nautre's Power Solar Attic Vent does not add to your electricity costs.

Wire less. Really.

Most active attic vents need to be connected to a home's electric wiring and need a trained electrician to install them. TheNature's Power Solar Attic Vent's elegant design and use of solar power make this type of connection unnecessary and makes its installation very user-friendly. No extra labour cost, no city permits.

Elegant design.

The Nature's Power Solar Attic Vent was designed to be clean, simple, and easy to install and maintain. The Solar Attic Vent is designed with a universal fit and can be added to existing passive vents making installation quick and easy. And because it doesn't modify your structure and uses free solar energy, there is no need for electrical wiring, expensive electrical installation, or city permits. The durable frame of the Solar Attic Vent also allows for easy angle adjustment to capture the maximum amount of sunlight for maximum fan efficiency and it can be placed wherever you need to improve circulation: attics, lofts, workshops, storage sheds, garages, and even barns.

And it all takes just 15 minutes.

Summer Season

During hot summer days, attic temperatures can exceed 71°C (160°F). The Nature’s Power solar attic ventilation can reduce that temperature drastically.

No matter how much insulation is in the attic, heat can still transfer to adjacent living spaces. In fact, extra insulation can add to increasing temperature as heat can still transfer into insulation; proper ventilation is necessary to evacuate this excess heat. In turn, heat reduction decreases expensive air conditioning energy usage and can extend the lifespan of an air conditioning system.
 

Winter Season

In cooler months moisture is a serious concern. Even with the use of vapour barriers to keep moisture from entering the attic, air leaks can still occur around ceiling fixtures and bathroom exhaust fans (among other places) that permit unwanted moisture to enter the attic. The moisture then condenses on framing members and on the inside of the roof deck, leading to the growth of mould, mildew, and rot.

The superior ventilation provided by the Nature’s Power Solar Attic Vent also helps to prevent ice dams which form as a result of heated air melting the bottom layer of roof snow which then freezes again as it runs onto the uninsulated eaves.

Installation


Roof

  1. Your installation package should include 4 -2” roof screws, 6 – ¾” self drilling mount screws, 4” of sealing tape, 3 Ty-raps and the panel mount.
  2. Locate the 6 – ¾”. Notice the adjustable 9” leg holes are offset. Attach the 9” leg to the bottom mount with the offset closest to the inside of the angle (Depending on your roof pitch, this may have to be moved for best adjustment later).
  3. Attach the roof mount to the solar panel. The 5” leg mounts at the single hole.
  4. Existing Attic Vent.
  5. Gently pry up existing vent approximately 4" at the bottom using a flat bar.
  6. Lift up vent and insert fan and check for fit.
  7. Carefully cut scored lines if necessary to fit and insert fan. Full size is for 75sqin vents.
  8. Ensure bottom flange seats in existing roof vent hole.
  9. Feed fan cable through the vent near the bottom, up and out, (not between the vent and shingles) then replace the vent to its original location. If you have a vent with a screen, cut a 1/2” slit in the screen and feed the cable through the slit.
  10. Mount solar panel to roof with 4 screws using the included sealing tape cut into 4 equal pieces at each screw location.
  11. Connect the fan cable to the solar panel and adjust solar panel.*
  12. CAPTURE MAXIMUM SUN! After connecting the fan cable to the solar panel, adjust solar panel to approximately 10 degrees from horizontal towards the south or southwest if possible.*
  13. After securing the panel to its most efficient adjustment, Ty-rap the cable to the adjustment leg to secure the cable.
  14. Finished unit.

* The mid summer is typically the hottest days. If possible, point the solar panel, flat to the sun, (the most exposure possible for maximum power) at approximately 3 o’clock sun. Peak heat and sun times may vary in your location.

WARNING: To protect yourself and others from injury, always exercise caution and use appropriate safety gear (restraints, safety glasses, gloves, etc.) when using a ladder, working on a rooftop, using power tools or handling a vent unit.

We own a two storey 2500 square foot home In Georgetown Ontario. Last summer when we were upgrading our roof shingles it was the perfect time to install the Solar Attic Vent. As our roofing company needed to remove the old attic vent it was not an issue for them to reinstall the vents.

Immediately we noticed that our air conditioner did not need to be set at 69-70 degrees, which we were comfortable with. We were able to reset our programmable thermostat to 74 degrees during the day and enjoy the exact same cool temperate levels in our home. The temperature differential between our main level and our second floor is not as noticeable. This is due to the fact that the stratified hot air build-up in our attic was released whenever the sun beamed onto the solar panel.

We haven’t heard any noticeable noise from the fan itself as it is very quiet. Quieter than a bathroom fan I would say and it is located on the outside of the roof. Our summer air-conditioning (electricity) bills have clearly gone down.

When I move to my next house I will definitely be installing the Solar Attic Vent.

- John Lambert, Georgetown ON

We own a side-split house in Chatham Ontario. Our attic is very well insulated, with good soffit ventilation. However, I always found it extremely hot in the upper level. You could actually feel the temperature change as you went up the stairs. Our air conditioning had difficulty cooling the upper level, and it was always at least 10 degrees hotter upstairs. The air conditioner had to be set low, in order to cool the upstairs. Still, we found it necessary to use fans, as well as the air conditioner in order to get a good nights sleep.

I had the solar vent kit installed into an existing roof vent, over the upper attic. Within a very few hours, the upstairs was noticeably cooler. There was very little temperature change between floors. During a full day of hot weather, we noticed very little change in the temperature from the lower lever to the upper level of the house. The air conditioner hardly came on at all. You could actually smell the stale, attic air in our back yard, so I know the vent was pulling that hot air out of the attic.

I was so impressed with the performance, that we had another fan kit installed into a vent in the lower section of the house.

The installation was quick, with virtually no disturbance to the shingles or the existing roof vent.

- Rick, Chatham ON

 

We thoroughly enjoy the installation. There is no sound at all from [the solar attic vent's] operation. It is aesthetically pleasing to our roof and best and most important of all to us is that we know it has reduced our air conditioning cooling costs considerably after being installed for only one year.

We would highly recommend this device to anyone and as well hope that in the future some government agency might consider rebating the full or partial cost of purchase and installation as an incentive to save on energy usage.

- Larry and Anne, Chatham ON

 

It was a pleasure to visit your business and see first-hand your Solat-poweted Attic Vent.
I can see the potential for employment creation and energy conservation. Besides being eco-friendly, one of the rnajor benefits of using solar powet is the fact that the energy is taken from the sun, negating the need fot wiring. This product could be an imponant addition to complement the Ontario Power Authority's "Peak Saver" program.

- Pat Hoy, M.P.P., Chatham ON

 

Since I have had you install the solar attic vents that you supply, I have noticed a substantial decrease in my air conditioning run time and the house is more comfortable as well. I believe that the solar powered vent you installed is well worth the money spent. I feel so confident in the units that I would like you to install them in my implement shed, daughters home and my son's home. Thanks very much!

- Mike, Chatham ON

 

We have purchased a solar attic fan and we are very happy with it. Since it was installed we have not had to turn on the air conditioning once to cool down the rooms. The device is very quiet and it will save on hydro. It also saves having to run the second air conditioner as we do not have a forced air furnace or central air. We will also buy another attic fan for the front part of our house in the future as we have an older two-storey home with lots of insulation.

Please note that my wife did not think it would work but to her surprise it worked great and was willing to tell everyone about it.

The government wants us to conserve energy so it would be nice if they would give some kind of rebate to help people put them in their homes.

The installation was quick and there was nothing done to the shingles and little to no mess in our attic.

- Gerald, Chatham ON

 

The unit is working extremely well. Other than two Mondays ago when it was smokin' hot (and we were out of town anyways on a camping trip) the house has been kept much cooler. We haven't had any reason to turn on our A/C at all.

FAQ


ISSI Solar-Powered Attic Vent FAQs

Q. What is a Solar-Powered Attic Vent (SPAV)?

  • A SPAV unit utilizes solar power to remove extreme heat in attic spaces in order to decrease energy use, increase quality of living and extend life expectancy of roofing materials.

Q. Where can I get one?

  • Our SPAV can be purchased right here on our web site! You can also find them at Lowe's locations across Canada!

Q. What will it do for me?

  • The solar powered roof vent provides many benefits best explained in terms of seasons:

Summer

  • Reduces attic temperatures. This helps cool the home, allowing for decreased reliance on expensive high-energy use air conditioning (a/c).
  • Approximate energy savings per house = 315 kWh1.
  • Potential financial savings per house = $50-60+/yr.
  • Estimated lifespan of unit: 20+ yrs.

1 Values obtained through extensive research conducted exclusively for ISSI by the Canadian Centre for Housing Technology (Natural Resources Canada, National Research Council of Canada) and the University of Ontario Institute of Technology.

  • Extends life of roofing materials. Asphalt shingles are designed to withstand abuse from the sun over many years, though they are subjected to damaging temperatures as a result of an over-heated attic. The greater ventilation offered by the ISSI SPAV lowers attic temperatures extending the life of roofing materials by an average of 3-5 years.

Winter 

  • Reduces rot, mildew and mould. As hot air cools on contact with roofing materials, it condenses leading to the development of rot, mildew and mould; all of which can cause serious damage. The ISSI SPAV actively improves attic air circulation reducing instances of rot and growth of mould and mildew.
  • Reduces ice dam formation on eave troughs. In poorly ventilated attics, heated air causes snow and ice to melt from the roof and run down to the eaves where it freezes again forming hazardous ice dams and may cause interior water damage. Increased ventilation from the ISSI SPAV actively decreases the chance of ice damming.

Q. Is a solar-powered unit better than what I have now?

  • In Canada today most homes are constructed with passive vent systems which rely on natural convection to provide sufficient air pressure for circulation and ventilation. Passive units are used to meet minimum provincial building code requirements whereas solar-powered units are used to actively improve the household quality of living with no increase to the electricity bill. 

Q What are the Specs?

  • Specs:
    • Solar Panel: 19 Watts, 28 VOC.
    • Fan: 19 Watts, 24 Volts. Rated for 50,000hrs at up to 400CFM.
    • Ventilation: Approx. 1,000sq.ft. (insulated attic area) at up to 400 Cubic Feet per Minute (CFM).
    • CSA/ESA approval not required as product is such low voltage.
    • All parts subject to a 10 year limited ISSI manufacturer’s warranty.

Q. Are there alternatives to solar-powered roof vents? What are they? 

  • Yes, there are alternatives such as wind powered roof vents, and electrically powered roof vents. However, both are flawed compared to SPAV units:
    • While the SPAV unit provides active circulation and ventilation on hot summer days, wind-powered units fail on the most uncomfortable summer days when there is no breeze at all. 
    • Electrically powered roof vents seem comparable to solar powered units. However, while the solar-powered unit decreases electricity costs (as it is powered by the sun), the electrically-powered unit increases electricity bills. 
    • Electrically powered roof vents have caused house fires.

Q. Can it be installed anywhere on my roof?

  • The ISSI SPAV unit is expertly designed for installation in three different rooftop methods: gable-end, soffit installations, and easy retro-fitting of existing roof vent.
  • he ISSI SPAV unit is compatible with all of the following types of vents:

 

Q. Who will install it? 

  • The ISSI SPAV is manufactured to require little to no roofing experience to perform the installation. Homeowners can install the unit themselves in about 15 minutes or hire a professional roofing contractor at their convenience. Please contact ISSI for a list of recommended installers.

Q. What do I do if I need warranty and/or repair service?

  • For your convenience, we are able to assist directly with inquiries about servicing your ISSI SPAV. Please visit our Contact section for service and warranty inquiries or if you would like to get in touch about anything else. We will get back to you as quickly as possible.

Q. Does the ISSI SPAV only operate during the day?

  • Yes. The ISSI SPAV is designed to lower peak energy usage when this relief is need most. The beauty of the SPAV is that it automatically adjusts the fan speed to the amount of available sunlight and, therefore, the amount of heat building up in your attic. The objective is to make the SPAV as simple as possible and to avoid unnecessary and bulky additions such as batteries, extra solar panels, and regulator components.

    Also, because the SPAV is designed simply to remove excess heat in summer and moisture in winter, no timers or controls are needed. In late winter and early spring, when ice damming is likely to happen in an attic because of moisture, the fan will become more exposed to sunlight as the snow melts and will remove excess moisture so that your roof can last longer. Air movement will help reduce the condensation as well as reducing the possibility of mold and rot within the attic.

Q. How does the SPAV help LDCs achieve provincial conservation targets? 

  • Flattens peak-load (reduces peak energy usage by 0.429kW per residence).
  • Reduces daily energy consumption (when a/c activated) by 315kWh per residence.
  • Changes coincidence factor (delays a/c activation).
  • Off-grid (not hard-wired).

Q. Would an LDC coupon program be well received by retailers? 

  • Large retailers contacted to-date (LOWE’S, Canadian Tire, Home Hardware, Home Depot) have indicated support for the SPAV technology to be included in a coupon program (along the lines of CFL/LED lightbulb rebates).
