Rated 5.0 out of 5.0 by Kiss5 Easy to install and works great.
The product was easy to install/replace existing attic fan. We are going "green" add recently installed solar power as well as added more insulation to the attic. We also installed the optional control until so the fan will switch to normal power when solar is not available and the attic still needs to be ventilated. The fan is very quiet compared to the old unit.

Rated 1.0 out of 5.0 by GL2013 Harder to install than they suggest
The side screws are placed under the fan hood which means removing the hood or buying a special right angle driver. Putting the hood back on is extremely difficult - trying to line-up an internal deflector, the bracket and the hood holes while sitting on a sloped roof.
The mounting holes (19" centers) do not line-up with standard 24" center roof joists so the screws only fasten to the roofing plywood - not good. How can the manufacturer figure its good for hurricane winds without being screwed to a joist? I added a cross member between joists and made sure the screws entered the crossmember as a fix.
I suggest the manufacturer modify the width to 26" with holes on 24" centers. That would solve both the problem of the hood covering the screw holes and screws not meeting main structural members.
Cheap screws too. One of the heads broke off.

Rated 5.0 out of 5.0 by sbodeck Best for including AC power
Very good fan for using existing AC power: Even on warm summer nights, (or humidity-trapping winter nights) fan will continue to work on the AC power backup, but switches back to solar power automatically when available. Tech Support was very competent - worked through a minor config issue quickly. Controller lets you see what's going on - that's been helpful for a difficult-to-access attic.

Rated 5.0 out of 5.0 by ENGINEER EXCELLENT PRODUCT AND GREAT CUSTOMER SERVICE
WE PREVIOUSLY PURCHASED ANOTHER BRAND AND TOOK IT BACK BECAUSE IT NEVER WORK WELL. MY HUSBAND PURCHASED A US SUNLIGHT FAN WITH A SOLAR CONTROLLER AND SO FAR WE HAVE NOTICED A DIFFERENCE IN OUR AIR CONDITIONER USE. THERE IS ALSO A 30% FEDERAL TAX CREDIT.
