This is the star of the year,
a great conjunction between a solid housing and fan/motor and the biggest PV
panels of ANY solar fan, at 60W. Compare to 6 years ago at
20W.
We are the only ones that have this fan setup as shown. And
it comes with a 25 year warranty on everything, and a company 10 year leakage
warranty. Put simply, they will not leak,
ever.
You can see how well the fan housing
"flashes" under the shingles, creating what the industry calls a
"positive drainage plain", relying only on gravity and not on
sealant.
Of course we also use sealant to prevent a wind driven rain from sneaking
upward.
