Solar Attic Fans in Hawaii?
Hello,
We have a low-slope (2:12) pitch and a very shallow attic space with R-19 fiberglass insulation in Hawaii.
The attic is ventilated with soffit and eve vents. I have been told – “you can’t have too much air intake.” So, I plan to increase the number of soffit vents.
We currently have a powered fan on the leeward side of the home in an eve vent — it seems to help reduce humidity in the attic (I do measure it).
Multiple roofers recommend adding a solar attic fan to our roof.
Does the fan actually release much heat?
I don’t think we have a condensation concern — warm attic and warm roof. But, what do I need to worry about in a ventilated attic in this climate?
Thank you,
Andrew

Thanks Steve -- my apologies. It was an accident.
