## Description

Remington Solar Builder Series 40 Watt Solar Attic Fan - Includes 110V Adapter for auto-Run Night time Operation - desertcart.com

Review: Works as Expected and Delivers RESULTS - Had my roofer install it for $100. My attic would routinely get into the 130-140F range during the summer. After having this installed, my attic stays within the 90-100F range. Insane performance and the inside of our home is much more comfortable.
Review: Wire connection - I purchased and installed two Solar Fans and they work great. Advantages: 1- Fan does not generate noise. You need to to the attic or climb the roof to find out if the fan is running or not. 2- Fan installation on the roof is easy, remove the existing turbine fan and the solar fan, fits the opening easily or with minimum adjustment. 3- instant Switching; from solar to electricity. 4- The design has tags, indicate, where and what to connect solar to the motor. Difficulties 1- The installer, took three trips for the installer to connect both the solar and electricity to the fan. The installer claimed the the solar connection has three prongs, green yellow, male connection and the third one. Plugging male to female connection in no problem but you you have to turn right and left to line until the cable to line the third connection. Otherwise you will hear tic tick. is replaced. This was a major nuisance. Fan effect The fan got installed in the month of July. The temperature in this month, ranges between 92 to 102 Fahrenheit, with heat index can reach up to 116 to 120 degrees. In the attic the temperature normally is 20 to 30 degrees higher than the outside temperature. The fan under extreme temperature conditions, has some effect; instead of facing heat from hot baking oven, it is decreased to do a quick job. The attic is tolerable around 90 degrees Fahrenheit. Please read about attic insulation to get better understanding. When you have the The attic insulation, the temperature is five degrees plus the outside temperature. This means if the temperature outside is 90 degrees, the temperature inside the attic is 95 degrees not 120 degrees [around this number]. To get the best benefits of the attic fan, you need to have clear path air pathway from the soffit vents to the attic. [Soffit Vents used under the eave to provide ventilation to attic area preventing mold and heat buildup.] At the end you need to have reasonable expectations. The fan is an important factor among other ones, when considering reducing the attic temperature in summer.

Quiet fan but definitely pricey. Manufacturer is hard to reach with Qs, though. Read all fine print in warranty if you ever have a claim.
