Solar-powered ventilation. Forever. For $0/month. Most active ventilation systems run on grid electricity. They add to your power bill every month, every summer. Some "solar" alternatives use a small auxiliary panel but still pull from the grid when they need real power. The Zula runs entirely on a 75W polycrystalline solar panel. No batteries to replace. No grid connection. No monthly cost — ever. Housing is recycled insulated plastic, fabricated in North Carolina. Rated to 80,000 working hours (over 9 years of continuous daytime operation). The product that pays for itself the first summer and then runs free for a decade.
