Power requirements will vary per trailer, but solar panels can power lighting and flushing mechanisms. Climate controls still require a standard 20-amp (110 volt) power supply though. This power can be supplied via a generator or standard outlet. The larger restroom trailers require 3 or 4 outlets, each with 20 Amps of power. These are typically 110 volts and need to be "dedicated" for use by the trailer.
