Increase the performance of a solar array 25% to 30%
single axis – follows the sun’s azimuth but not its altitude
dual axis – follows the sun’s azimuth and altitude
Typically trackers are used in large utility scale or commercial solar panel installation, although I have heard of home very savvy homeowners who built their own tracking systems, but I have no idea how much performance they increased and the ease of operation of a home built tracking systems. When most people ask me if a tracking system is good for their home solar power system, I let people know that current tracking technology is not at a point in which it makes sense for smaller solar array installations.
The graph above shows the performance of the RayTracker by EI Innovations over a conventional fixed mount solar array. The company claims that there is no scheduled maintenance associated with their tracking system, that’s pretty impressive. Wouldn’t you say so?
