Grid-connected PV system is considered as electricity generated solar cell system which is connected to the grid utilities. This paper characterizes an exhibiting and simulating of PV system that executed with MATLAB /Simulink. The impact of solar irradiances as well as ambient temperature performances of PV models is investigated and noted that a lower temperature provides maximum power higher so that the open circuit voltage is larger. Furthermore, if the temperature is low, then a considerably short circuit current is low too. 1. INTRODUCTION The vast improvement of the recent common economy is a crisis factor of energy as well as the environment, that needs to decrease the requirement on conventional energy besides level improvement of utilization and enlargement of the energy resources such as renewable gradually [1], [2]. By concentrating on renewable source types, solar photovoltaic (PV) can be considered as the main contributors in the world energy sources due to unlimited offer features of power generation in addition to its clean (i.e. no emitted pollution and considers100% environment friendly), therefore it may be a completely renewable energy technology which has afforded an expansion potential in addition to their world's quickest developing industries [3], [4]. A photovoltaic (PV) system utilizes a solar cell for converting the solar energy to electricity with depends on the photoelectric effect. PV system basically is a cell which may be classified as mono-crystalline, poly-crystalline, organic cell, amorphous, and Nano-PV cells. Now the technology of PV can be used in various applications like plants of solar power, PV grid-connected, home-produced usage, power communication, satellites, and currently aircrafts as well as electric vehicle applications [5]-[7]. In applications of photovoltaic (PV) system, it's necessary to design a comprehensive system to activate the solar cells (SCs) with optimal conditions and maximum efficiencies. The Maximum power point (MPP) is changing greatly with depending on the sunlight angle on the panel surface in addition to cell temperature, therefore the MPP may not be considered as the load operating point of PV system. PV systems can be designed for comprising many required modules with the purpose of supplying reliable energy for the grid [8], [9]. The feeding of electricity by Grid-connected PV systems are directly active with electrical network and working in parallel with a conventional power source. These systems had been satisfying an exponential

This work presents the design and simulation of 10 kW grid-connected photovoltaic (PV) systems as feasible power generators for the Hashemite University campus (32.05°N, 36.06°E). The simulation is performed to justify the accuracy and reliability of such design using PV-SOL and Meteonorm simulation software. In the primary simulation runs a set of parameters including the module power, PV-solar panel size, inverter type, global radiation and angle of inclination were used. The results of those runs lead to the final simulation parameters which are used for the 10 kW PV system. This work also presents a comparison between the performances of different PV panel sizes and different inclination angles. The final design of 10-kW PV-system consists of 33 PV panels of 300 W each and three inverters of 3.4 kW each. In order to highlight the economical and ecological effectiveness and the promising potential of the proposed system, a comparison between the costs of one kWh generated by our system with that of the public electricity tariff has been conducted.

ERJ. Engineering Research Journal, 2022
Photovoltaic (PV) technology is in the forefront of renewable energy and gained a lot of attention as a very promising green technology towards direct solar energy conversion to electricity. So, enhancing the PV solar cell performance is an important target for improving PV system performance. In this paper, a recent algorithm called Arithmetic Optimization Algorithm (AOA) is proposed to find the optimal PV model parameters to build a Simulink model for an actual case study of the New and Renewable Energy Authority (NREA) 42 kW PV system. The results of the proposed AOA are compared with that obtained by means of particle swarm optimizer (PSO). Also, performance analysis is introduced for the practical measurements from the grid-connected PV system. Energy is measured for the installed PV system at the NREA in Cairo and the proposed system is simulated during daily weather conditions to test its operational performance based on simulation results. The system is installed to produce 2.17 MWh/year of energy production. Based on the optimal parameters for the study module using the proposed AOA, the detailed Simulink model of small-scale 42 kW PV system is accurately designed and connected to the utility grid. Furthermore, the output energy of the investigated system, with the aid of the proposed AOA, is efficiently estimated compared with the actual energy generated of case study.

THE PERFORMANCE ANALYSIS OF A GRID CONNECTED PHOTOVOLTAIC SYSTEM
The International Physics Conference Tirana, 2015
Performance, quality and reliability issues are becoming more and more important for the emerging photovoltaic markets worldwide. PV-grid connected systems allows consumer to reduce energy consumption from the electricity grid and, also, to feed excessive energy into the grid. This paper presents the results obtained from monitoring the first grid connected PV system in Albania which is composed by two sets of 12 panels of poly crystalline silicon modules connected in parallel; each with open circuit voltage 44.8V DC and nominal power is 190 Wp. The system is installed on the roof of the building of Institute of Geosciences, Energy, Water and Environment. The system was monitored for one year. Electrical energy generated was fed through a low voltage grid, 220 V, 50 Hz, to the consumer. Monthly, daily and annual performance parameters of the PV system are evaluated which include: energy generated, system efficiency, inverter efficiency and array efficiency. The performance of PV system changes due to meteorological condition, technology of PV arrays, inverter technology and sizing. During monitoring period the efficiency of PV module ranged from around 17% for low insolation (around 500 W/m 2) to around 10% for highest value of insolation (around 1000 W/m 2). Also relationship between DC output power and AC output power seems to be almost linear, however for low irradiances, below 500 W/m 2 , losses in inverter increase. The equation fitting better the data seems to be Y =-0.02 ln(x) + 0.237 and correlation coefficient R 2 =0.834.

This paper presents some analytical studies on the performance of grid connected solar photovoltaic system with different parameters in Rajasthan. The various factors that are considered for performance evaluation are: solar irradiation, ambience, tilt angle, orientation and shading. Rajasthan is rich in solar energy with varying ambience. Thus, due to change in climatic condition the PV system performance varies from place to place to a considerable extent. This influences the energy yield as well as economics of such system. In this paper a performance evaluation have been carried out for a 5 MW p crystalline silicon solar photovoltaic power plant in Rajasthan. As a part of the plant design, considerations have been taken in account on aesthetic, safety and cost aspects. The optimised annual energy yield of the 5 MW p is in the order of 8 GWh at a tilt angle of 22 o , average ambient temperature of 26 o Cand relative humidity (RH) of 60%. The minimum yield observed was about 7 GWhat 28 o tilt angle, average ambient temperature of 20 o C and RH of 75%. These studies justified on the implementation of photovoltaic system in urban areas of developing countries where peak load demand is very high.
