[IEEE 2018 4th International Conference for Convergence in Technology (I2CT) - Mangalore, India (2018.10.27-2018.10.28)] 2018 4th International Conference for Convergence in Technology (I2CT) - Performance Analysis of a 48 kWp Grid connected Rooftop Photovoltaic System
摘要： The dropping market prices of power generated from solar photovoltaics is making it an attractive option for decentralized power in the form of rooftop and ground mounted systems. In the present scenario, the presence of solar photovoltaics in the energy mix is continuously increasing. Thus, it is important to monitor the performance of these systems to identify deviations from expected performance and to maintain higher system efficiency. This paper presents the details of performance analysis study conducted on a 48 kWp rooftop solar PV system located in the Northern India monitored over a 1 year period. The actual measured values of system performance parameters are compared to results obtained from simulating the systems using the PVsyst software. The values estimated using PVsyst for performance ratio and yearly average of system efficiency are 82% and 13.67%. The yearly average value of CUF estimated is 16.14%.The results of this study can aid in providing a glimpse into the operation of solar PV systems operating in the North Indian climate and can help in carrying out future comparative studies. The results obtained in the current study are also compared with the performance parameters of other plants operating in India.

Assessment of power generation performance characteristics using different solar photovoltaic technologies
摘要： Solar energy is a relatively free renewable, clean, green, and environmentally friendly energy resource produced from the sun, using different technologies like solar thermal and photovoltaic (PV) modules to generate heat and electricity, respectively. This paper aims to assess and compare the power generation performance characteristics of different solar PV module technologies by simulation, deploying identical input temperature and irradiance parameters. The solar PV designs were simulated using PVsyst Version 6.73 for 26.0 kW annual power and 42.9 MWh/year annual yields using the climate data of Sydney, Australia. The results show that monocrystalline solar technologies needed an area of 163m2, while polycrystalline and thin films needed areas of 173m2 and 260m2 respectively to generate 42.9MWh annual yield. The monocrystalline PV modules are more efficient at solar energy conversion than polycrystalline and thin film technologies, respectively (94.2% and 62.7%). The symmetric semi-toroid dome of sun heights against azimuthal angles show 13 bimodal pyriforms, that cut the azimuths at least twice on each of the optimisation lines. These optimal solution points were visible for every sunlight hour of between 6 and 18 hours (inclusive). They show convex sets of global optima (or local optima) with one minimum in the interval of convexity. Also, each of the minimum points for each of the 13 directed fish-like bimodal pyriforms was on azimuth. However, the assessment of respective PV module characteristics with respect to variation of irradiation and temperature, show that the general results from simulation displayed disparate changes in the voltages and currents of the generated power with respect to different solar PV modules. The proposed semi-toroid model indicates that many optimisation solutions for easier, cheaper, quicker and more efficient power generation are possible with appropriate design. It is recommended that the installation of a single-axis solar tracker or maximum power point tracker could overcome the azimuth angle effect.

摘要： Today most of the countries are fulfilling their energy need from fossil fuel resources, which are vastly depleting and era of fossil fuel is gradually ending. Power generation using fossil fuel is creating harmful effect on environment, leading to global warming which has become matter of great concern. Massive use of these fuels, release large amount of waste heat, causing thermal pollution in surrounding area, leading to destroy of various types of plant and animal life. In case of nuclear power plants, disposal of radioactive wastes and release of radioactivity during accident creates long term sever problems. Therefore every country is now embarking on search of alternative sources of energy, specifically, solar energy, which is inexhaustible source of energy and freely available in almost all parts of the world. Our research team suggested solar PV plant of 10 Kwp for Shree Samarth Agro-Tech Foundation, Which is a small scale Agricultural based business enterprise operated by farmer’s self-help group, located in Solapur District of Maharashtra State, India. Thus, our research team, tried to provide technology up gradation to these conventional diesel generator powered jaggery making units that helps in reducing green house gas (GHG) emission. Detailed performance analysis of the proposed system will be carried out using PVsyst simulation tool.

摘要： The aim of this study is to develop a procedure for the design of institutional grid-connected solar PV (Photovoltaic) systems using campus buildings' roofs and car parking shades. This procedure was developed and validated in the design of a single phase 10 kW solar photovoltaic system at King Faisal University, Al Hofuf, and Kingdom of Saudi Arabia. The method consists of 12 grid steps including resources assessment, site selection; access and requirements; supporting structure and roof type, area, orientation, strength and shading. Once the roof and supporting structure are selected, the facility layout, required grounding and lightning protection are finalized according to IEC Standards. The final stage of the design is to testing the facility. The 10 kW facility has been operating since March 2014. The results for 2014 and 2015 indicate that daily energy production were slightly below the rated values and in some months of the years, the station better that the simulated lightning performance and protection, system w subsequent near future. PVSyst as modification The software. the in necessary study in the considered would be using.

New approach for maximizing generation and optimal utilization of available space for solar PV system
摘要： To accomplish an enormous demand of power with solar energy, a cost effective and optimum system has to be developed which works in synchronisation with the existing grid. The Government in developing countries like India is providing momentous opportunities and marvellous schemes to promote renewable energy sources like solar for generating power. This paper aims to analyse the generation of power from solar photovoltaic (PV) systems economically and efficiently as it is always a challenge for the design engineer to develop an economical and efficient solar PV system. Apart from technical issues, structural aspects also affect the power generation from PV modules. This paper proposes an innovative design of non-movable tracking system that enhances the power generation of PV modules by just providing two grooves in the mounting structure in place of the tracking system. A formula for the optimum space calculation for PV installation is also proposed in this paper. A comparative analysis of total annual energy generated by the hardware setup and the results obtained using software of the rooftop solar PV system has also been analysed for practical consideration. To verify the results, first, the system has been simulated using the PVSYST software considering all practical and existing realistic losses like PV loss due to irradiance and temperature, array soil loss, module quality loss, array mismatch loss, ohmic wiring loss, and inverter loss which formulate a bonafide case of consideration and then hardware implementation of the proposed system. The hardware and software results have been compared to analyse the proposed topologies adopted to address the aforesaid problems.
