Dual Axis Solar Tracker for Solar Panel with Wireless Switching

摘要

A solar panel that tracks the sunlight was designed and implemented. As a result, tracking was achieved. The system designed was a working model of dual axis tracker. Dual trackers are most suitable in regions where there is a change in the position of the sun. We have also seen that the dual axis trackers are more efficient than the single axis trackers [1]. The prototype was implemented with the minimum resources. The circuitry was kept simple, while ensuring that the efficiency is not affected. Further, wireless switching is added to ease the switching of the system, in case we want to shut down the system if we are moving out. Wireless switching for load point gives us a choice to either switch to battery mode (using stored energy from storage battery) or to switch AC mode (using energy directly from grid) (Table 5 and Fig. 7).
