Solar Trackers & Reliability

Looking at a solar tracker, and one sees a simple mechanical structure. Probably something anybody could build? Now add to that a requirement for it to operate over a 20 year lifespan, and the picture has quickly changed. Try to think of a electrical/mechanical structure which has operated non-stop, during all types of weather, for the last 20 years.

When designing and building a solar tracker, a goal of 20 year operational life must be considered because the additional performance gain can quickly erode with unexpected maintenance costs. Baring lightning or other extreme power surges, the electronics and software will easily last 20 years when designed correctly. The main problems are mechanical, gears, motors and bearings.

If you are about to venture out and design a new solar tracker, please give us a call to discuss your options. With our remote managed controllers, we see the day-to-day operational troubles, and have helped many tracker manufacturers improve their designs. There’s no need to retry paths leading to troublesome designs.
