Solar attic fans play an important role in the long term maintenance and and healthy environment of your home by eliminating the things that promote the growth of mold. Mold can only grow if you allow it. There are three important ingredients for mold growth: heat, moisture, and darkness. Solar fans remove two of the three. Every time you take a shower, do dishes, or wash the laundry, moisture is released into the air. This moisture eventually rises into your attic and settles in the insulation and on the framework of your roof. The same thing happens as your home warms up. Heat rises and gets trapped in the attic. It is already dark up there, so mold and mildew have everything that they need to grow. Solar attic ventilation will help prevent these things from growing, which will have countless impacts on your home and health. 

20 Watt Solar Attic Fans are perfect for the energy conscious homeowner. These adjustable, solar attic fans will pay for themselves in as little as one or two summers, and after that the money becomes all profits. The included ultra-strong aluminum fan blades will provide maximum ventilation and air-flow, which will provide the perfect ventilation for larger homes.
