The electric power-driven economy of Ghana has necessitated the continual balance of demand with supply by making use of economically feasible sources of energy. In this paper, a 2.5 MW grid connected solar photovoltaic (PV) power plant in Navrongo is evaluated for its performance in 2014. The plant's output energy, including PV modules, and system efficiencies with other performance indicators were analysed based on IEC 61724 standard. The average ambient and PV module temperature determined was 31°C and 45°C respectively, with 514 W/m 2 as the average global radiation. The monthly daily average energy generated was 10.7 MWh with 320.5 MWh and 3845.8 MWh as total monthly average and annual generated energy respectively, during the period. The respective average array, reference, and final yields in hours per day (h/d) were 0.48, 0.51 and 4.13 as well as 18% Capacity Factor, and 81% Performance Ration. A total of 3768.0 MWh was delivered and the PV modules, inverter and system efficiencies were 10.1%, 84%, and 10.3% respectively. In conclusion, it was identified that, dust accumulations on the PV modules surface, significantly reduces the output power due to inefficient use of solar irradiation. Effective and efficient cleaning of the PV modules surface is therefore recommended for improved efficiency of the plant. The aim of this research; therefore; which was to evaluate the performance of the Navrongo solar PV power plant and optimise the energy output efficiently by the use of modelling and simulation has been achieved.

As one of the renewable energy sources, sunlight or solar energy is considered appropriate to be one of the alternative sources of electrical energy that can be used. In this study, an on-grid system simulation model was carried out using PV. The goal is to find out the characteristics of the energy obtained using the control logic algorithm. In this simulation model design, previously calculations were carried out to determine pv capacity, because it will be adjusted to the power capacity used in residential houses. In this discussion, it is in accordance with the electricity needs of residential houses of 1,500 Watts or hourly energy conumsion of 1.5 KWh. This electrical load will be on at 07.00 to 17.00, meaning that this electric load will consume electric power for 10 hours. Then the total energy consumed per day is 1.5 KWh. In this simulation, 2 100 Wp (Watt peak) solar panels with an output voltage of 12 V DC are used. In a day, it can more or less produce electricity of 200 Wp x 10 hours of heating = 2,000 Wh.

Purpose Solar photovoltaic (PV) is commonly used as a renewable energy source to provide electrical power to customers. This research establishes a method for testing the performance reliability of large grid-connected PV power systems. Solar PV can turn unrestricted amounts of sunlight into energy without releasing carbon dioxide or other contaminants into the atmosphere. Because of these advantages, large-scale solar PV generation has been increasingly incorporated into power grids to meet energy demand. The capability of the installation and the position of the PV are the most important considerations for a utility company when installing solar PV generation in their system. Because of the unpredictability of sunlight, the amount of solar penetration in a device is generally restricted by reliability constraints. PV power systems are made up of five PV modules, with three of them needing to be operational at the same time. In other words, three out of five. Then there is a charge controller and a battery bank with three batteries, two of which must be consecutively be in operation. i.e. two out of three. Inverter and two distributors, all of which were involved at the same time. i.e. two out of two. In order to evaluate real-world grid-connected PV networks, state enumeration is used. To measure the reliability of PV systems, a collection of reliability indices has been created. Furthermore, detailed sensitivity tests are carried out to examine the effect of various factors on the efficiency of PV power systems. Every module's test results on a realistic 10-kW PV system. To see how the model works in practice, many scenarios are considered. Tables and graphs are used to show the findings. Design/methodology/approach The system of first-order differential equations is formulated and solved using Laplace transforms using regenerative point techniques. Several scenarios were examined to determine the impact of the model under consideration. The calculations were done with Maple 13 software. Findings The authors get availability, reliability, mean time to failure (MTTF), MTTF sensitivity and gain feature in this research. To measure the reliability of PV systems, a collection of reliability indices has been created. Furthermore, detailed sensitivity tests are carried out to examine the effect of various factors on the efficiency of PV power systems. Originality/value This is the authors' original copy of the paper. Because of the importance of the study, the references are well-cited. Nothing from any previously published articles or textbooks has been withdrawn.
