Project Summary

The world natural resources are depleting day by day, we are looking for alternate energy sources to overcome the power shortage.Renewable energy may be used as a alternate energy source due to its climate friendly nature. Energy from renewable does not emit any harmful gases so    it is also helpful in cleaning the pollution from the society. It can solve the issue of global warming. Renewable energy is a type of clean and green energy that is totally extract from the environment. There are many types of renewable energy but solar and wind are more prominent these days .In our project we used solar as a renewable energy because it is more economical and more efficient than wind because sunlight is always present in the day but wind is not present all the time . Solar PV frames are widely used today because of the basic construction work, one of the various sources of stability. An electronic inverter is utilized to convert DC power acquired from the array of solar panel .The approach to working with hybrid inverters batteries is better than some other conventional inverters and also for DC power source  During imbalances, energy fluctuations and unreliable grid structures, hybrid converter-based control frameworks are used to solve power demand issues. Considering power shortages, hybrid inverters are the best fit for a variety of situations. The direction and intensity of sunlight in PV panels is constantly changing, so the output of PV panels is consistent. This problem can be solved by interrupting the maximum power of the solar cell device with the Maximum Power Point Tracking Controller.

Project Objectives

•Due to inherent losses that occur in photovoltaic systems, it is essential that the maximum power should be extracted.

•The intent is to create an extremely efficient charge controller that would be able to monitor the power generated by photovoltaic array.

• To deliver the maximum power to the battery bank during varying atmospheric conditions.

•The major principle of MPPT is to extract the maximum available power from PV module by making them operate at the most efficient voltage (maximum power point).

Project Implementation Method

The composition of this project is to design an Mppt based solar hybrid system,where three input sources that is solar panel, battery and AC supply from electric supply company Wapda are utilized and project depends on power selection
operation. On the other hand if there is inaccessibility of both solar panel and battery sources, at that point power from AC supply is utilized as satisfying energy need. On the off chance that both energy sources that is solar and battery are not operational, then system will automatically shift to third source which is from AC supply company Wapda. In case, if the solar and AC supply from Wapda are not available, in that scenario our need is fulfilled from the battery as a energy origin. Three power sources are utilized that is solar, battery and AC supply electric company Wapda. Power generated from battery and panel is Direct current (DC),while power from electric company Wapda is alternating (AC) which is rectified into DC through full wave rectification and then give it to the controller .Thus, microcontroller is used to make a comparison between the voltages. Charge regulator
has basic capacity, it controls the power source, which to be kept dynamic or inactive. It simultaneously charge the battery and besides passes on capacity to the load. The yield of sun powered board alters with the course of sun. On the off chance that the sun is straight over the board, we will get most extreme voltage, yet in the event that the sun is away from the board, by then voltage won’t be sufficient. Hence, for making its yield voltage consistent, we use MPPT (maximum power point technique) charge control. Basically MPPT is a buck-uphold converter, which keeps up the yield voltage of board. In the occasion that sun is straight over the board and the yield voltage is high, the buck-help converter will go probably as a buck converter and it will ventured down the voltage to an ideal level. For our circumstance the force from the sun powered board is moreover ventured down through buck converter and thereafter took care of into the microcontroller through entryway driver circuit. Moreover, if sun is away from the board and voltage is low, the converter will go probably as a lift converter and it will ventured up the voltage to an ideal level.
