Provide a cost effective power solution to atmospheric and road weather stations for SunWize customer Vaisala as part of an Arizona Department of Transportation project


SunWize® Power Ready System, 440 watt solar array

The project involved placing Vaisala Road Weather Stations along the highways of Arizona, seventeen sites in all. The sites are used to collect atmospheric and road weather data to be used by highway maintenance officials to make decisions about winter impacts to roads. These weather stations are placed in very remote locations where communications and power can be extremely expensive to provide. The solution was to use a completely wireless installation that used solar for power and satellite or digital cell for communication. The Arizona climate makes solar an excellent solution with the limited cloud cover and extended daylight.
