A solar tracking system with a plurality of tracking assemblies (12) moved by a single motor (14). A method and system that prevents overloading the motor or tripping a circuit breaker due to an obstructed or impeded tracker includes sensing movement (162) of the tracker assemblies (12) and entering into obstruction clearing modes. Obstruction clearing mode 1 (OCM1) (168) is a high frequency adjustable mode that prompts movement for an adjustable period of time. If movement commences, the system returns to a normal mode. If there is no movement, the system enters into an obstruction clearing mode 2 (OCM2) (176) with is an adjustable lower frequency series of attempts. If there is no movement, no further attempts are made. Each of these steps are monitored and controlled remotely. There are two types of secure connections for drivelines, torque tubes (16, 110, 220) or affixing driveline linkages (130) for high torque conditions. |
