How to Install a Solar Attic Fan.

Did you ever think of adding some kind of attic ventilation to your house to keep it cooler during exhausting hot summer days or just to get rid of excessive humidity? There are quite a few solar powered attic fans on the market.
Your Solar Link now offers a new model of whisper quiet technology 20″ diameter blade (the largest blade on the market) Multi-Purpose Solar Attic Fans to ventilate attics and to keep your house cooler.

Its newly designed co-polymer UV resistant shroud is created specifically to increase airflow and to isolate the solar module from heat transfer. Unlike metal it will not rust, corrode, or dent. These particular solar powered attic fans rely on a 30-watts (unlike earlier models with 10-20-watts panels) solar panel to power a DC motor when the sun is shining or even in partially cloudy climates. They are great for both residential and commercial use.
Solar powered fans usually exhaust air at a rate of 800 to 1200 CFM and are set up with intake vents (such as soffit and gable vents) to provide high-capacity powered ventilation without any electric operating costs. Multi-Purpose Solar Attic Fans from Your Solar Link exhaust air at a rate of 2400 CFM plus and are perfect for 1500 – 3000 square feet attic space homes. Most vents are positioned high on the roof, near the ridge, and combined with soffit or gable vents for balanced intake and exhaust air streams.

Because they cost nothing to operate, solar attic fans are much more affordable than conventional powered attic fans. By reducing your attic temperature, attic fans can help reduce summertime cooling loads, providing ventilation without added utility cost.

Steps to install a Solar Attic Fan:

1. In attic, mark location of solar powered vent between two roof rafters.
2. Drive nail through center of vent location.
3. Install roof brackets and fall-arrest system to roof.
4. Scribe outline of vent’s flashing on roof using homemade dowel compass.
5. Cut shingles along circular outline with a utility knife.
6. Pull nails and remove shingles from within the circle.
7. Use compass to scribe hole for vent onto roof sheathing.
8. Cut hole in roof with a reciprocating saw.
9. Remove shingles from around the vent opening.
10. Apply continuous bead of tri-polymer roofing cement around hole.
11. Set roof vent over hole, then screw the fan’s flashing to roof.
12. Apply more caulking around flashing.
13. Replace all the roof shingles around the vent fan with 1 ½-inch roofing nails.
