Introduction

In many houses, it gets too hot as warm air enters from the attic. Turning on the air conditioner, you try to remove the heat from the rooms to make the living conditions more comfortable. However, at the same time, the red-hot attic continues to heat the house. Such a confrontation is expensive and does not lead to the desired results.

To create a comfortable microclimate in a dwelling, attic ventilation is needed. This measure is also necessary to maintain the strength of the roof, as well as to prevent the formation of condensate.

Solar panels are already being used to power a wide variety of equipment: from mobile gadgets to electric vehicles. Attic fans are not an exception. Their installation will save you a good amount of money: you do not need to contact an electrician for help since it is not necessary to connect any wires. In addition, your future electricity bills will only please you.

Still, you need to be well-versed when it comes to the features and specifications of these devices. Therefore, our article presents the best Top 10 solar powered attic fans on the market, as well as a consumer’s guide on what to consider when buying them.

Working principle of the solar-powered attic ventilator 

Solar attic fans are environmentally friendly, as in their work the energy source is the sun, not electricity. As for the design, they consist of a mounting bracket, fan, and solar panels to power it.

The principle of operation is not different from traditional ventilators: solar-powered fans work by displacing hot air, thereby making the air temperature in the attic closer to the outside one.

Guide to buy solar powered attic fan

Because the attic ventilator requires an initial investment, it is important to understand that their efficiency and performance strongly depends on its type, along with some external factors. For example, the type and color of the roof, insulation of the house, and type of the cooling system. Therefore, when buying such a device, pay attention to several key points.

  • The design and functionality of attic fans vary by manufacturers and models. They can be of different sizes, shapes, and colors.
  • Attic fans can be installed on the roof, curb or gable. The choice of installation location depends on the shape of the roof (flat or pitched), the actual inclination of the roof, and directly on the attic area.
  • To ensure adequate ventilation, pay attention to the venting capacity of the device. This characteristic depends on the size of the solar panel. 
  • Generally, the main disadvantage of attic fans is the increased noise level. Despite the fact that the latest models, judging by the ads, work quietly, if you are sensitive to noise, you should carefully consider the type of the fan. Especially if it will be placed in the immediate vicinity of the bedrooms.
  • When choosing a solar attic fan, factors such as quality of materials, efficiency and manufacturer’s warranty should also be considered.
