Best Solar Attic Fan of 2020: Top 5 Recommendations

Surprisingly, the conditions of an attic room can affect the entire house. Depending on the season and regional climate, the specifics on how the attic conditions the home will vary. In cold regions, and especially in winter, a warm attic can often cause the snow on the roof to melt, which could lead to roof damage if it is not maintained properly. Keeping the attic cool during winter and snowfall will ultimately prevent this problem.

Conversely, in summer, and especially in hot and humid regions, an unventilated attic that is not being cooled will trap the hot air and cause it to recirculate, creating a warmer house than is necessary. This will also cause damage to the roof. In the case where moisture begins to form, which is especially common in humid regions, it will develop mold and mildew all over the house.

Finding an energy-efficient way to cool the attic is of importance if you intend to condition your home into a livable place. For this reason, the best and most efficient means to control the temperature of the attic is to install a solar-powered attic fan. Not only will it improve ventilation, but it will also keep the attic cool without spending too much energy. In fact, most attic fans that are powered by solar cells will not hike up the utility bill at all. Here we have compiled a list of the best solar powered attic fans on the market.
