Off-Grid residents already know that ceiling fans are a great alternative to Air-conditioning for the simple reason that they use far, far less power.
At a time of power outages due to peak consumption of air-conditioning, that is a socially useful benefit. It is technically possible to run a 110 AC off solar panels in very bright sunlight, but only at the expense of just about every other appliance in the home. And only with a fairly massive battery pack. And only for a relatively short time. Celing fans on the other hand can keep going all day on a fairly low power supply. Some were designed especially for running directly off solar panels with no battery – for use in drying cannabis in California’s Emerald triangle.
