Increasing the Charging Efficiency of Solar Panel and Improving the Performance by Using PIC Controller and Gear Motor Based Cleaning Method on Voltage Drop

Abstract

Solar energy sources play an Vital role in Generation of electricity (Energy). There are various renewable energy resources like wind, solar, geothermal, ocean thermal, tidal and biomass can be used for generation of energy or else we can say electricity for meeting our daily energy needs. The best option for electricity generation can be Sun (solar energy) as it is available in abundance and is free to harness. On an average the sun shines for about 6hrs annually in India also the sunshine shines in India for about 9 months in a year. Electricity (Energy) from the sun can be generated through the solar photo voltaic modules (SPV). The Photo voltaic cells comes in various power output to meet the load requirement. Maximization of power from a solar photo voltaic module (SPV) is of special interest as the efficiency of the SPV module is very low. A peak power tracker is used for extracting the maximum power from the photo voltaic module. The present work describes the controlling the peak power (SPPC) for the SPV module connected to a battery which is used as a load. A Microcontroller is used for control of the algorithm. The peak power controller is developed and tested successfully in the laboratory. Solar peak power controller is used in photovoltaic systems to maximize the photovoltaic array output power, irrespective of the temperature and irradiation conditions and of the load electrical characteristics .The main difference between the method used in the proposed SPPC system and other techniques used in the past is that the PV array output power is used to directly control the dc/dc converter, thus reducing the complexity of the system. The resulting system has high- efficiency, lower-cost and can be easily modified to handle more energy sources (e.g., wind-generators).The efficiency of the panel decreases as time passes due to the accumulation of dust particle on the panel ,which is hampering and an big hindrance for charging the battery or else we can say load which is connected to the set up ,for this we would use an geared motor which would be connected with the wiper and it would help in cleaning the panel on daily basis as the voltage drop would be there the current study has been done on the basis of LDR sensor which is not so appropriate for the industrial application
