GST - Single Axis Tracking System

For most PV power plants, the Single Axis Tracker is the top pick due to its cost performance ratio. Compared to the fixed system there is about a 10% additional cost, but a 10% to 25% increase of power generation. Thus, the Internal Rate of Return is a benefit. When selecting a solar system, there are three basic categories to consider: the product cost, the installation cost, and the cost of 20 years of maintenance. According to American EPC companies such as SunPower, First Solar and others, there is an additional 10% maintenance cost for tracking systems compared to fixed systems. The benefits of trackers for investors should make them the preferred choice.
