The age of industrialization and modernization has increased energy demands globally. Solar energy has been recognized as an inexhaustible source of energy and has been applied for desalination and electricity generation. Among different non-conventional energy resources, Solar Energy (SE) is one of the main contributors to the global energy system. A photovoltaic system (PS) is applied to produce SE using photovoltaic cells. The selection of a solar panel includes many intricate factors involving both subjective and quantifiable parameters; therefore, it can be regarded as a complex Multi-Criteria Decision-Making (MCDM) problem. As the uncertainty commonly occurs in the selection of an ideal solar panel, the theory of Pythagorean fuzzy sets has been proven as one of the flexible and superior tools to deal with the uncertainty and ambiguity that arise in real-life applications. The aim of the study is to present an MCDM framework for solving the Solar Panel Selection (SPS) problem within the Pythagorean fuzzy (PF) environment. For this, first, a new integrated method is proposed based on the Stepwise Weight Assessment Ratio Analysis (SWARA) and VlseKriterijumska Optimizcija I Kaompromisno Resenje (VIKOR) approaches in the Pythagorean fuzzy sets (PFSs) context. In the proposed approach, subjective weights of the evaluation criteria are calculated by the SWARA method, and the preference order of alternatives is decided by the VIKOR method in the PF context. The criteria weights evaluated by this approach involve the imprecision of experts’ opinions, which makes them more comprehensible. The computational procedure of the proposed methodology is established through a case study of the SPS problem under PF environment, which proves the applicability and efficiency of the proposed method. Furthermore, this study performs sensitivity analysis to reveal the stability of the developed framework. This analysis signifies that the solar panel option R4 constantly secures its highest ranking despite how the parameter values vary. In addition, a comparative study is discussed to analyze the validity of the obtained result. The results show that the proposed approach is more efficient and applicable with previously developed methods in the PFS environment.

Energy consumption is a major factor in relation to an organization's costs and expenses, determining the need to apply methods that can minimize or reduce these expenses as much as possible. Having these factors in context, the present work aims to present the technical feasibility of implementing a project that uses solar energy through the on-grid solar system to supply the energy demand of a company. The methodology used was the descriptive, in which several data were collected and documentations were analyzed that supported and justified the elaboration of a photovoltaic project and development of the budget and analysis of the costs of a solar energy system. Through the results obtained, it was possible to arrive at a solar project that would be able to establish the necessary power for the company for a cost of R $ 20,916.96 and a payback of 5 years and 5 months. Thus, it is possible to conclude that the photovoltaic system is viable in its use and application, not only because of the advantages associated with the environment, but taking into account its self-sustainability over time and with a useful life of up to 25 years.

Solar energy modelling is increasingly popular, important, and economic significant in solving energy crisis for big cities. It is a clean and renewable resource of energy that can be utilized to accommodate individual or group of buildings electrical power as well as for indoor heating. Implementing photovoltaic system (PV) in urban areas is one of the best options to solve power crisis over expansion of urban and the growth of population. However, as the spaces for solar panel installation in cities are getting limited nowadays, the available strategic options are only at the rooftop and façade of the building. Thus, accurate information and selecting building with the highest potential solar energy amount collected is essential in energy planning, environmental conservation, and sustainable development of the city. Estimating the solar energy/radiation from rooftop and facade are indeed having a limitation - the shadows from other neighbouring buildings. The implementation of this solar estimation project for Istanbul uses CityGML LoD2-LoD3. The model and analyses were carried out using Unity 3D Game engine with development of several customized tools and functionalities. The results show the estimation of potential solar energy received for the whole area per day, week, month and year thus decision for installing the solar panel could be made. We strongly believe the Unity game engine platform could be utilized for near future 3D mapping visualization purposes.

Abstract We face many situations in day to day life where multi-polar statistics is offered. The prevailing models like Pythagorean fuzzy sets and m-polar fuzzy sets become inoperable in handling such situation efficiently e.g. if someone wishes to invest his capital in some scheme, he would for sure like to know repeated information about pros and cons of that scheme. Pythagorean m-polar fuzzy sets (PmFSs) serve as the most appropriate model to cope with such situations. The motivation behind this article is to extend the notions of PmFSs coined by Naeem et al. (J Intell Fuzzy Syst 37(6): 8441–8458, 2019) and introduce some new operations and results on PmFSs. Owing to the idea of Pythagorean m-polar fuzzy relation, we render an application in the selection of most appropriate life partner.

Solar energy systems are becoming potential option for numerous applications. It has been shown that the application of solar energy system is strongly dependent on criteria’s used in their evaluation. Single criteria evaluation of solar energy systems has shown its deficiency due to limited possibility to compare them with other potential options. In particular, present economic system is based on the econometric analysis with priority given to the optimum obtained by the economically justified optimization function. For this reason, it has become needed to introduce multi-criteria evaluation procedure in the assessment of solar energy system and its comparison with other potential options. This paper presents evaluation of the solar photovoltaic system and its comparison with other renewable energy system options for stand-alone application. In this evaluation following energy systems will be taking into a consideration: grid electric energy supply, wind energy system, gas turbine with cogeneration, small hydro energy system and solar photo-voltaic energy system. In the evaluation of these systems the multi-criteria evaluation procedure is used. The multi-criteria evaluation procedure will comprise a following criteria’s: economic, environmental, technological and social indicators. Each of indicators will be based on the sub-criteria which are defined in the paper. The sustainability index as the agglomeration function indicators will be used in the determination of the rating among the options under consideration. Special emphasize in evaluation is given to to the conditional priority of indicators leading to the investigation of the effect of the indicator priority to the finale rating among options.

The article is a continuation of the article entitled "Reconciliation of the solar climate of Krasnodar for the effective operation of solar panels in residential buildings" published in the Bulletin of BSTU named after V.G. Shukhov in 2017. At present, the vast majority of stationary weather stations are located at a sufficiently large distance from the zone in which it is necessary to assess the potential of renewable energy resources. The article presents the results of field studies of the solar climate of Krasnodar conducted from 2014 to 2020. The results of the study are compared with normative documentation and a climate guide. The use of solar panels is important factor to reduce harmful emissions into the atmosphere. For the correct selection of the number of solar panels, it is necessary to know the exact amount of solar energy that will fall on this panel. This information allows to calculate the amount of energy that will be generated by the building’s solar energy system or solar power station. The correct selection of the number of solar panels affects the quality of life of people and allows to fully cover the energy consumption of buildings and structures using solar energy as the main source of energy.

Solar Photovoltaic System

Brunei Darussalam is a country that receives high amounts of solar irradiation annually as it is located near the equator. With the abundance of oil & natural gas resources, the country has one of the cheapest electricity costs in the world. This would in turn make solar power underutilized. The purpose of this project is to design a solar system for Brunei’s medium sized residence to meet the daily energy demands. A comprehensive analysis was conducted on the solar photovoltaic system for determining the optimum sized parts and components. The design process was divided into detailed sections so that the values are calculated using PVSyst simulation software. The simulation also predicted the specific energy production, performance evaluation, and the losses. Cost analysis was also conducted to find the efficiency and the feasibility of the system. The designed solar energy system has a capacity of 60 kWp, producing 75 MWh of usable energy annually. This system uses 66% of the energy available from the sun to generate electricity which covers the electrical demand of Brunei’s residences.
