This paper focused on the procedure to test PV modules according to the IEC 61215 standard and compare these modules for prediction of the actual energy production and comparing the different technologies (Mono Crystalline, Multi Crystalline, CdTe, CIGS and A-Si). Here we are taking both the Crystalline and Thin film PV modules which are being evaluated on the basis of the datasheet results which...
Electrical transmission system is a very complex structure. To provide quality power to the end user customer. It is required to control the power by avoiding the congestion effect. To meet the quality power distributed generation may be adopted at different location nearer to the load. This paper investigate the performance of a renewable energy based grid connected system through load voltage ride...
This paper proposes a special type of converter with solar photovoltaic cell for extracting maximum amount of power from a variable source. The converter topology uses a special characteristics which enables it to extract maximum power from the source. Partial shading is a very critical problem which sometimes leads to permanent damage of the cell. This effect also reduces the system performance and...
Of the 1.24 billion people in the country, more than 450 million people do not have access to electricity as well as over 95,000 villages still remain dark after sunset. Even the electrified villages suffer power cuts of 15 hours or more on a daily basis. These problems compel us to resort to other energy sources that are inexhaustible. The paper proposes analysis and comparative study of Hybrid Renewable...

Incorporating the understanding of contact technology, its related problems and the possible solutions is utmost necessary in this era in order to achieve results which will ultimately show better device performance. The contact layer electrically couples metal layer with semiconductor layer and forms a semiconducting contact having low specific contact resistance. The fact that ohmic contact plays...
This paper provide a brief idea about the modeling of solar photovoltaic grid connected system. As the grid is a highly nonlinear system so it requires highly efficient inverter so as to minimize total harmonic distortion. It is also required to find out the exact position where maximum power can be injected. Moreover the paper tries to explain the controlling method used for controlling the duty...
This paper describes about the solar photovoltaic cell and its different modelling phenomena. In solar cell modelling generally curve fitting is adopted to calculate or extract the parameter. However for better calculation of error it is not recommended to adopt the curve fitting. the objective behind this paper is to find a suitable optimization technique so that it can be applied to all other models...
Transmission and distribution of power over the tie line depends upon the amount of load connected to it. As the entire power system is a completely non linear network so steady state analysis of the power system is a very difficult task. In order to maintain the system voltage and frequency with that of the change in the loads demand it is require to modify the system suitable controller. If the...
