The SunRise 1050 attic fan, which mounts on the roof, runs on solar power so no wiring or electricity is needed. By removing heat and moisture from the attic, the unit reduces energy consumption, extends the life of HVAC equipment and shingles, and keeps insulation dry, the firm claims. The unit moves 1,050 cfm. It comes fully assembled and can be installed in less than an hour, says the company. 866-599-3566. www.sunrisesolar.net.
