  • simple solar powered desk fan. needed: small solar panel and a computer cooling fan. the breeze is equivalent to a standard desk fan. I used 1.5 watt solar panel and a 40 CFM 80mm computer cooling fan. many different panel and fan combinations can be used. most computer cooling fans will run on most smaller 6 to 12 Volt solar panels. Of note, with the fan and panel I used; there is no danger of hurting your fingers if you touch the blades. they easily stop if you touch them. tip: try to salvage a fan from an old computer.
