How does a solar attic fan work?
Solar attic fans work independently from the rest of the home?s power and heating and cooling systems. DC motors in fans are powered entirely by their own small solar panel, and therefore do not require a connection to any existing electrical system. As such, they cost nothing to operate. In summer months, fans extract hot air that accumulates in the attic space and roof areas of homes, which helps maintain cooler indoor temperatures and reduces the load placed on air conditioning equipment. Your home will be more comfortable and you?ll use less electricity, which will save you money. In winter months, fans operate at a much lower rate (as the amount of sunlight is reduced and is less direct), allowing the home to maintain its heat while also venting moisture out of attic space and roof areas, which helps prevent wet insulation, mildew, decay, cracking plaster, peeling paint and roof damage.
