A self-contained solar roof vent: a 200mm polycrystalline panel drives a 5V brushless fan rated at 950 cubic feet per hour. It needs no wiring, no battery and no electrical work, and it starts working in overcast light rather than only direct sun. It suits sheds, greenhouses, lofts, boats and RVs where running mains power is awkward. Against mains-powered extractors it moves less air and stops at night, but it installs through a single 82mm hole and costs nothing to run.

This is a solar-powered roof fan that ventilates and helps prevent heat build-up in sheds, greenhouses, lofts, boats, RVs, caravans and motorhomes. It has an ultra low profile, aerodynamic design and runs quietly. It extracts 950 cubic feet of air per hour.
A polycrystalline solar panel powers a brushless DC motor, so no wiring or electrical work is needed. The panel does not need intense direct sunlight. In full sunlight of up to 40,000 lux the fan runs continuously. At about 8,000 lux it works intermittently. It may not work in winter light because of low lux levels.
The fan starts within 20 seconds of decent sunlight and extracts warm air automatically. Built-in capacitors store a little charge, so when a cloud passes it slows down until full sun returns. On overcast spring or summer days it works intermittently, for example 20 seconds on, then 20 seconds charging.
