This method gives a solution for the solar panels to get the maximum power and for effective utilization. The hardware is developed for PV array and various parameters like voltage, current, power(for both DC and AC), energy is measured. The system is connected to the controlling which monitoringthe solar panels functional working. PIC MCU is used as a controller. By incorporating the IOT technology the data received from the system are send to the cloud, from through internet the user can monitor the parameters. Thus, the main objective of the monitoring system is to ensure that solar panels operate smoothly and to easily detect critical problems. Keywords — Internet of Things (IOT), PV, SolarPanel, PIC MCU. ----------------------------------------************************---------------------------------- I. INTRODUCTION Power generation are spreaded over India among the government departments that lead to many losses. Because of consuming more power by some others than they need this leads to loss of more power. There is no more alternative source available for producing an electricity in large amount. One of the top source available is sunlight with which we can take natural power for our daily life. Solar power plants convert the solar energy into solar electricity. The sun is the largest source of energy in the form of heat and light energy. Solar Power has a high potential to make a more impact on the electricity requirements in home appliances and industries. That the sun gives as much energy onto the earth in one day that equals the annual energy requirement is enough to judge the amount of solar energy that goes untapped. It can be used to supply electricity to homes, commercial settings and so on. In this project we have a solar panel for creating electricity from sunlight. The solar panel consists of an array of PV cells. Photovoltaic cells are connected electrically in series or parallel circuits to produce higher voltages, electricity and power levels. Photovoltaic modules consist of PV cell circuits sealed in an environmentally protective laminate, andare the fundamental building blocks of PV systems. Photovoltaic panels include one or more PV modules assembled as a pre-wired, field- installable unit. A photovoltaic array is the complete power- generating unit, consisting of many number of PV modules and panels.The amount of current or voltage produced from solar panel is taken readingwhich is in the form of DC . This information is transformed to microcontroller. The power generated can be used for initiating some loads in home; the obtained power is converted to AC by an inverter. After converting the amount of current/ voltage is measured and given to microcontroller. The microcontroller in turn displays the amount of current and voltage produced from solar panel. It also display the power and energy consumed. Finally the acquired power can be used for another types of loads II. PROPOSED SYSTEM The proposed system can be used to measure both AC and DC electrical parameters and also the RESEARCH ARTICLE OPEN ACCESS
