After meeting Alden Hathaway and touring his net-zero home, homeowner Frank Rothwell decides an attic fan is needed to help reduce the heat in his home and the overall cooling costs. Rothwell desired something low maintenance, low noise and low cast -- a solar powered fan meets all three of his desires. The beauty of the solar fan? The greatest heat of the day creates electricity that will cool the attic by removing the same heat. Rothwell met with engineer and solar designer Jeff Gilbert to discuss his needs. Gilbert brings two models to discuss with Rothwell: - Solar attic fan kit (Rothwell's selection) - well-suited for gable ventilation. The separate units for collection, ventilation and control make the system versatile. The kit includes a 40-watt solar panel, a thermostat / controller and a 12-volt DC powered 11" diameter fan. For best results, Gilbert suggests always selecting a solar panel with double the output required by the fan used.
- All-in-one unit - an adjustable 10-watt photovoltaic panel sits atop the fan. The unit is designed for rooftop insulation and needs to be positioned so that the panel can be angled properly. The kit comes with instructions for cutting the roof and proper installation.
