LJW is an expert in the installation of remote power and stand alone power photovoltaic systems.
Stand alone power systems often use a tracking system because it gives increased output by up to 40% compared to a fixed axis system. It also changes the pattern of production, by creating more power at the start and end of the day. With stand alone power, this is important because it reduces the demand on the batteries.
This short video is a larger system and is interesting to watch.
