Solar Powered Battery Voltage Control using LabVIEW

To meet the power demands, an alternative source of energy is essential to produce power. Sun being renewable energy, it is used. LDRs are fixed near the panel. The solar tracking is done using arduino which is interfaced with LDRs. When the light falls on LDRs the intensity changes, based on the higher intensity side the solar panel is titled with the help of DC motor using relay circuits to move in forward and backward directions. Thus the lead acid battery is charged by the energy from the panel. In addition to that, the battery is used to drive different loads. The battery is charged according to the operating voltage of the load connected to it. If the battery has threshold voltage to operate the load, it will be operated. when the battery runs out of charge, it will be charged and when the battery is overcharged, the load is disconnected from the battery. For monitoring the panel and controlling the batteries the real values from the panel and the batteries are given to arduino and it is interfaced with Lab VIEW.
