P4 Tracker
PSE’s high-precision outdoor trackers give you top-quality testing options. We offer two different tracking systems, the larger and more accurate Tracker P4 and the smaller Tracker P2.
Our tracking systems can be combined with different measurement equipment to fulfill requirements of solar thermal collector and PV module test standards. Combined with our Heliosensor it is also possible to reach higher tracking accuracies required for testing concentrating solar technologies.
