The yearly energy yield of a Solar Photovoltaic (SPV) system is a rendition pointer utilized by the erector to determine the output energy generated by it. From the energy speculation, the payback period and the return on investment can be contemplated. The system energy yield formula consists of many parameters, the most important of which is the SPV inverter efficiency. The European and peak (maximum) efficiency factors from the inverter data sheet are typically utilized, but this utilization is unsound because the SPV does not always work at the peak of its effectiveness due to varying irradiance. The inverter's weighted efficiency is considered more sound as it deems the inverter output power peculiarities. The European weighted efficiency is the most widely accepted inverter efficiency determination. Since it is derived and documented on a rimmed European irradiance profile, it may not be appropriate for inverters constructed in different climatic conditions, especially in the equatorial and subtropical environmental regions. This work aims to formulate a fangled weighted efficiency equation for the inverter's work in the Iraqi environment (especially in Baghdad city as a case study) documented on the IEC 61683: 1999 Standard and Irradiance-Duration curve. The sophisticated formula is endorsed on experimental data from the field using an SMA-SB-4000-TL inverter. It was found that the speculated energy yield using the derived efficiency formula for the Baghdad environment closely matches the energy yield of an original 4.0 KW SPV inverter system with only 1% difference between the determined and acquired values. This means that the employment of the Baghdad weighted efficiency in place of the European or peak weighted efficiency will result in a sounder speculation of the system energy yield, return on investment, and payback duration of the SPV system project.

Photovoltaic (PV) arrays have been recognized as one of the main clean renewable sources of electrical energy. In practice, PV arrays are subject to unavoidable non-uniform partial shading (PS) due to clouds, buildings, dust, etc. PS causes the hot spot problem, mismatch losses, and output power degradation. A widely used approach to mitigate the effect of PS is dynamic reconfiguration, where, the interconnection of PV panels is modified according to the shading condition to achieve maximum output. Dynamic reconfiguration techniques use sensors, a programmable controller, and a switch matrix for optimal operation. However, they have drawbacks such as system complexity and scalability issues. For instance, reducing the number of switches limits the flexibility of the reconfiguration algorithm. In this paper, an automatic dynamic reconfiguration scheme is proposed in which PV panel irradiation activity controls the interconnection of switches, without the need for a programmable controller. A modular building block is proposed from which easily scalable PV arrays can be constructed in a hierarchical manner. Experimental and analytic results have verified the effectiveness of the proposed reconfiguration scheme.

“…It is possible to increase the energy intensity and, as a consequence, the temperature of the source of the heat by focusing sunbeams [4][5][6].Because this is a technology that can be used for both electrical and thermal conversions, and because it employs a completely clean and infinite source of energy, it is obvious that this is a solution that can assist to reduce the amount of fossil fuel that is utilized [5][6][7][8]. A mirror arrangement is used in all methods of concentrating solar power (CSP) to focus sunlight onto a single target and convert it to heat [9].…”

Solar energy has piqued people's curiosity since the dawn of civilization, and the technology for harvesting it has advanced at a rapid pace. The development of technology to increase the efficiency of the solar system is of critical relevance due to the energy difficulties that civilization has been facing. Scientists have used the solar concentrated system for several years since it allows for the concentration of solar energy into a concentrate, allowing for a significant increase in energy efficiency. A parabolic dish setup is described in this article as a dish-shaped concentrating collector that reflects solar energy onto a receiver located at the focal point. This concentrator is set atop a framework with assumption of a two-axis tracking system to track the sunlight. Typically, the acquired heat is utilized directly by a heat engine constructed on the receiver that travels with the dish. Typically, the acquired heat is utilized directly by a heat engine constructed on the receiver that travels with the dish. The suggested dish could achieve very high temperatures and might be utilized in solar reactors to generate high-temperature solar fuels. Even though dishes are seldom utilized commercially for power production, engines are now favored for power conversion. Consequently, the purpose of this study is to explain the benefits of this technology in a world where fossil fuel usage is a genuine issue that society must address.
