This research presents the performance of four grid-connected solar photovoltaic (PV) systems installed at the Adamawa State College of Health Technology, Mubi, Adamawa, Nigeria. The system consists of 3.5 kWp each of four different PV technologies. The mis and psi cells manufactured by China Sunergy and Conergy comprised 14 modules with a power capacity of 250 watts. The asi produced by Moser Baer consists of 10 modules, each having 350 watts, and the CIS manufactured by Solar Frontier has 20 modules, each having 175 watts. The PV was observed and recorded data from January 2022 to December 2022. The system performance was analyzed using eleven evaluation criteria. Based on the technical assessment of the systems for this location, the asi solar PV has the best annual performance. It demonstrated the most favorable performance ratio (PR) and capacity factor (CF) of 90.7% and 27.6%, respectively, when considering energy output, system yields, performance ratio, and capacity ratio. On the other hand, the msi system, manufactured by China Sunergy, exhibited significant efficiencies at both the panel and system levels, with values of 14.3% and 13.7%, respectively. This system stood out for its minimal overall losses, recorded at 7.78 hours, demonstrating superior efficiency and lower overall losses than the other systems under study. This study is critical because the result will provide valuable information to researchers in identifying the appropriate PV systems suitable for Nigeria. In addition, it will assist PV installers and manufacturers with updated information on the PV system with the best performance.

This paper demonstrates the investigation of the acquired outcomes from consistent information observing a 467.2 kWp solar photovoltaic (SPV) framework commissioned on the roofs of three separate high-rise buildings, which are located at the location of 26.9585° N and 80.9992° E. Onside real-time performance for this system was investigated for three years, 2018–2020; this system contains 1460 SPV panels of 320 Wp each, having 20 PV panels per string, 09 DC/AC power conditioning units (PCU), and a SCADA (supervisory control and data acquisition) system for monitoring the other necessary parts of a grid-interactive SPV system. The outcomes of the different buildings are compared with each other to analyze the power output at the same input conditions. Hardware components of the plants with approximately the same ratings (P2 ~ 108.8 kWp + P3 ~ 128 kWp) are compared (with P1 ~ 230.4 kWp). Simulation modeling of the year 2020 in PVsyst tool for generated energy, Performance Ratio (PR), and Capacity Utilization Factor (CUF) are carried out additionally and compared with the installed rooftop grid-interactive SPV system of 467.2 kWp (~P1 + P2 + P3) at the site. Numerous performance parameters such as array efficiency, inverter efficiency, system efficiency, Performance Ratio (PR), and Capacity Utilization Factor (CUF) of the plant are evaluated and compared with already installed systems in different regions of the world. These points demonstrate great feedback to framework architects, workers, designers, and energy suppliers regarding the genuine limit and plausibility of the framework they can offer to clients. Moreover, one of the environmental benefits of the SPV plant is that the 467.2 kWp PV framework reduces the tremendous measure of CO2, SO2, and NOX that is discharged into the air.

“…Increased initial investment and limited lifetime of a PV array makes it essential for the user to take out the utmost power from the PV system (Jacob et al, 2018;Li et al, 2017b) (Gaurav et al, 2015). The nonlinear i-v characteristics of PV array (Chimtavee and Ketjoy, 2012) and the revolution and rotation of the earth around the sun requires the application of maximum power point tracking (MPPT) to the system. Accordingly, grid connected PV systems have turn out to be very popular because they do not require battery back-ups to make sure about the MPPT.…”

Purpose Increased investment of a photovoltaic (PV) array makes it essential for the client to attain better results from the PV system. The nonlinearity of the PV array and the revolution and rotation of the earth require the appliance of maximum power point tracking (MPPT) to the system. Accordingly, grid connected PV systems have turn out to be renowned, because they do not require battery back-ups to accomplish MPPT. Stand-alone systems could also attain MPPT; however, they require appropriate battery back-ups for this function. Design/methodology/approach This survey intends to formulate a review on the PV-based microgrid (MG) systems. Here, the literature analyses on diverse techniques associated with PV-based MG systems. It reviews 65 research papers and states the significant analysis. Initially, the analysis depicts various controllers that are contributed in different papers. Subsequently, the analysis also focuses on various features such as PV capacity and inverter topology, and it also analyses the renewable grid source that are exploited in each paper.
