solar roof fans
I can only say that prior to having 2 solar roof fans installed in attic space the temperature was during hottest days 135 degrees +. since installation the temperature again on hottest days has never exceeded 105 degrees. space is 2600 sq feet. Also received federal tax credit and am able to store stuff in attic space without damage from heat as it was before installation. would i do it again, YES. the goal was to keep air moving and yes i can see if fans are working by looking back through attic space at the fans. No they do not work at night because they are solar but then the temperature cools at night anyway----right?
