The Importance of Solar Attic Fans

Why Solar Attic Fans Are Essential

Solar attic fans (or solar roof vents) tackle two critical issues:

Overheating Attics: Attics can reach 150°F+ in summer, forcing your AC to work harder.

Moisture Damage: Trapped humidity promotes mold, wood rot, and ice dams in winter.

Key Benefits:

Slash cooling costs by 20–30% (U.S. Department of Energy).

Extend roof lifespan by preventing heat and moisture damage.

Zero electricity bills—100% solar-powered.

Easy DIY installation with no wiring.
