The need to electrify all rural areas in India is quite compelling. However, the focus has now shifted from traditional fuel-based systems to generate electricity to renewable sources for energy generation. Though there are subsidies and policies that encourage the use of solar Photovoltaic (PV) systems, there is a need for an appropriate framework. This framework could not only offer substantial directions but it would also act as grounds to enhance rural electrification in India using solar PVs. From this perspective, the current research attempts to structure an innovative framework for solar PV system that could facilitate rural electrification in India. In particular, the district of Damoh in Madhya Pradesh was chosen as there are many villages without electricity in this district. PVsyst software was utilized to simulate the outcomes that included mathematical models and diverse components based on PV, for simulation. Three designs were developed to facilitate the simulation. These included; PVs linked with microgrid devoid of battery, individual PV systems without microgrid link and solar PVs linked to microgrid with battey. The framework for rural electrification using solar PVs will offer policy makers with insights with regards to implementing PV systems. It will also offer inputs as to the feasibility of implementing a specific system on several parameters. These would comprise of; number of households within a village, detached households etc. Nonetheless, research in future is also warranted to explore the scope for other sources of renewable energy.

Small scale PV systems are mainly used in Distributed Generating systems (DG).The problem with PV DG system is for designing this system high voltage gain need to be required. In order to achieve this high gain we are choosing Grid connected PV system that is large scale Grid connected PV system In Grid connected PV system Power Electronic devices such as converters and inverters are main parts along with PV panels. In our work we have designed a solar PV system with varying irradiation in MATLAB/SIMULINK and enhance its output capacity before its integration with the grid. To design a suitable controller for per phase designed power converter such that it produces better output results than the traditional converter. The controller has to be designed along with buck boost control of DC output from the system instead of designing a whole new and separate control algorithm for inverter. It was concluded that active power output from the system from approximately 1MW in conventional inverter has improved to 12MW in the proposed scheme.

Sunlight is energy that can be converted into electrical energy. One of the uses is by applying it to the roof ofthe building. The application in this building has restrictions such as the placement of the PV moduleshorizontally and vertically. In the study comparing the results of energy obtained from the PV system withhorizontal and vertical positions with a standard degree angle in the direction of azimuth sunlight. Positionusing the horizontal produces more energy and reaches a performance ratio of more than 80%.
