My husband and I bought our first home last year and this summer has been so rude. Especially the rooms upstairs have been so hot even after all the fans weâve got there. Now we have decided to get attic fan installed. We are looking for solar power attic fan preferably. So I want to ask people who have installed something like this in their homes. Is it worth to install solar power attic fans? I sit more expensive than the conventional one? Could you tell me about solar power attic fans? Please get back to me with some appropriate reviews. Thanks.
