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.

Abstract Battery systems are critical factors in the effective use of renewable energy systems because the self-production of electricity by renewables for self-consumption has become profitable for building applications. This study investigates the appropriate capacity of the Battery Energy Storage System (BESS) installed in all-electric zero energy power houses (AEZEPHs). The AEZEPH used for this study is a highly energy-efficient house. Its criteria indicate that all the electrical energy within the home is covered based on the generated electricity from on-site renewable energy systems, including that the annual net site energy use is almost equal to zero. The experiment for measured data of electricity consumed and generated in the buildings is conducted for a year (i.e., Jan. through Dec. 2014). Based on the measured data, patterns of the electricity consumed by the AEZEPH and generated by an on-site renewable energy system (i.e., photovoltaic (PV) system), and BESS's appropriate capacity is then analyzed and evaluated using the EES analysis tool, named Poly-sun. This study indicates that self-consumption can be increased up to 66% when the ESS system is installed and used during operating hours of the PV system. The amount of received electricity during the week tends to be reduced by about two times.

The energy demand of buildings represents in the balance of heat use and heat consumption of energy complex in the Slovak national economy second largest savings potential. Their complex energy demands is the sum of total investment input to ensure thermal protection and annual operational demands of particular energy systems during their lifetime in building. The application of energy systems based on thermal solar systems reduces energy consumption and operating costs of building for support heating and domestic hot water as well as savings of non-renewable fossil fuels. Correctly designed solar energy system depends on many characteristics, i. e. appropriate solar collector area and tank volume, collector tilt and orientation as well as quality of used components. The evaluation of thermal solar system components by calculation software shows how can be the original thermal solar system improved by means of performance. The system performance can be improved of more than 31 % than in given system by changing four thermal solar system parameters such as heat loss coefficient and aperture area of used solar collector, storage tank volume and its height and diameter ratio.

In today’s world we are going towards the major share of renewable energy to reduce the effect Green House Gases (GHG) in the atmosphere. The limitation of energy sources which produces clean energy, the rise in the pollution in the environment, and programs initiated by the Indian Government have encouraged lots of open field researches on Solar Photovoltaic Systems or Solar Energy Systems. As producing the clean and renewable energy is main component of energy sector, solar photovoltaic could be considered as an alternative in various regions. Although Solar Photovoltaic does have different advantages and can be used for various purposes, but also there are several challenges for it. This paper took a whole overview of the advantages and uses of Solar Photovoltaic and barriers in their adaptation/opportunities.

System Sustainability

The sustainable development of energy systems does not only involve the use of renewable energy resources but the increase in their efficiency as well, enabling society to maximise the benefits of their consumption. The production of electrical energy from clean and renewable sources contributes to lowered fossil fuel exploitation and the reduction of its damaging effect on the environment. This is a way to reach the global target of sustainable development - striking a balance between resource consumption and the achievable natural cycle regeneration. Environmental protection is in the focus of attention. Namely, when energy system sustainability is assessed, in addition to the ecological sustainability assessment (based on life cycle analysis - LCA), attention should be paid to the decrease in energy quality in energy processes (exergy loss). This paper presents the thermodynamic approach to energy system sustainability assessment by applying life cycle exergy analysis (LCEA). The key issue is the assessment of systems which use sustainable energy sources: the wind turbine and the stand-alone photovoltaic solar system.

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.

Despite the success of the German Energiewende in increasing the production of electricity from renewables and the positive global spillover effects of renewable technologies, one of the lessons learned is the insight that simply shifting to renewables and recommending improving energy efficiency is not sufficient to lower greenhouse gas emissions. Combined with the expected radical change of technologies, this requires a more profound understanding of our energy systems. Therefore, in contrast to many conventional energy economy approaches, we propose a deepened structural analysis that covers the full energy value chain from the required functionalities for mechanical, thermal and specific electric energy services via application and transformation technologies up to primary energy. This deepened structural approach opens and substantially enhances our understanding of policy designs that are compatible with the Paris Agreement and Sustainable Development Goals. We discover the essential role of four energy grids, namely for electricity, heat, gas, and information as the key for integrating all components of a newly structured energy system. Consequently, we conclude that policy strategies focusing on individual components of an energy system like shifting to renewables may, from a comprehensive perspective on more sustainable energy systems, prove even counterproductive.

Selection Of

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.
