QBotix is introducing a track based robot to align solar panels towards the sun called Solbot. This is a single axis tracking system, as opposed to a dual axis tracker, which also accounts for what time of year it is. Aiming the solar panels towards the sun allows the solar panels to be more efficient and get more energy from the sun. Wikipedia states:
It is estimated that trackers are used in at least 85% of commercial installations greater than 1MW from 2009 to 2012.
Solbot runs on a track, much like a monorail and can service up to 200 solar panels in 40 minutes. When connecting with each panel, Solbot adjusts the angle of the panel, but also collects data about the panel. Solbot also has a certified IP-65 rating, meaning it is impervious to dust and water.
For larger solar panel arrays, more Solbots can be added to the system. When not servicing the solar panels, Solbot returns home to the charging station.
QBotix expects to have the first commercial customer up and running by the end of September.
