Design and Development of Pure Mechanical Solar Tracking System Using Double Acting Hydraulic Actuator

摘要

In recent years, the increasing global interest in the conservation of environment has provided a fresh motivation for research in the area of solar energy utilization. It is clear that an external power source is necessary for energizing the sun tracking unit. The solar receiver efficiency can be improved by converting this to mechanical tracking system. Solar tracking is a mechanism for orienting an object towards the sun. Here we are using double acting hydraulic actuator to track sun. Tracking Mechanism is pure mechanical means it utilizes a counter weight, rack and pinion gear and double acting actuator to form the tracking system.
