The dual fan, solar powered fan for a portable enclosure, like a portable toilet structure includes: a first upper fan unit that includes a first main housing for mounting to a sidewall of the portable toilet enclosure. The first main housing consists of: a first backing plate for attaching to an upper section of the sidewall, a first vent hole surround that passes at least partially through a first fan hole in the sidewall, an electrically powered, first motorized fan for positioning over the first vent hole surround to serve as an exhaust fan for the portable toilet enclosure, and a solar panel for affixing to the first backing plate, said solar panel being electrically connected to the first motorized exhaust fan.

The second lower fan unit for this invention includes a second main housing for mounting to the same sidewall of the portable enclosure a set distance away from the first fan unit. That second main housing includes: a second backing plate for attaching to a lower section the sidewall the set distance from the first fan unit, a second vent hole surround that passes at least partially through a second fan hole in the sidewall, and an electrically powered, second motorized fan for positioning over the second vent hole surround to serve as an intake fan for the portable toilet enclosure. Lastly, there is included an electrical connection from the solar panel in the first main connection to the second motorized fan of the second main housing.
