Solar energy is most powerful and trending source among all renewable energy sources. For utility point of view, solar power is available at each place but problem is that the efficiency of solar cell is very low. In addition, the efficiency of solar cell under different atmospheric conditions like different temperature and irradiation, the power we get from the solar cell is different and same as that the efficiency is also changed so for analyzing the behavior of solar cell, we have analyzed mono-crystalline solar cell for different temperature and irradiation and results are taken. For analysis point of view, the mono crystalline solar cell is analyzed into solar simulator under different values of irradiation and temperature and then experimental results for the same are taken. For cross checking the results that we got from the solar simulator, we have done mathematical modelling of solar cell into MATLAB and then the simulated results are taken, the similar kind of results came from the simulation and experimental readings as well.

In the conditions of climate change and the scarcity of natural resources, the future of energy is increasingly associated with the development of the so-called green energy. Its development is reflected in the European Commission strategic vision to transition to a climate-neutral economy. This is a challenge that the Central and Eastern European (CEE) countries, members of the EU, are also trying to meet. In recent years, these countries have seen an increase in the share of renewable energy and a reduction in greenhouse gas emissions (GGE). On the other hand, basing the energy sector on unstable energy sources (photovoltaics and wind technologies) may imply new challenges on the way to sustainable development. These are old problems in a new version (ecology, diversification of supplies) and new ones related to the features of renewable energy sources (RES; instability, dispersion). The aim of the article was to classify, on the basis of taxonomic methods, the CEE countries from the point of view of green energy transformation (original indicator) and to predict new threats to Romania, Poland, and Bulgaria, the countries representing different groups according to the applied classification. The issues presented are part of a holistic view of RES and can be useful in energy policy.

Today, almost all of civilisation is based on energy. To a large extent, energy is being continuously acquired from non-renewable raw materials deposited in the Earth’s crust. Renewable sources provide alternative, infinite energy resources, particularly solar radiation, wind power and water movement. The Paris Agreement envisages the complete abandonment of fossil fuels by the year 2050 for all EU Member States. From a technical point of view, a complete transition to renewable energy sources (RES) is very difficult to achieve. In the case of Poland, the way to 100% RES is longer and more complex than in most EU countries. The main purpose of the conducted analysis was to thoroughly assess the possibilities for obtaining energy from inexhaustible sources as well as the benefits of various procedures in order to develop an optimal set of solutions. The aim of the presented study is to indicate the possibilities for the development of construction investments in the field of renewable energy sources that have an inseparable impact on spatial management. To achieve this aim, the method of research of the available literature and legislation was applied.

The energy used in the built-up environment represents at least 40% of the total energy consumed, out of which, at least 60% is required for heating, cooling and domestic hot water (DHW). Within the European Union, more than 6,000 communities (i.e. over 9%) use district heating systems, the majority of which use the conversion of fossil fuels as a source of energy. This aspect, which is corroborated by the directives of the EU legislation on the use of renewable energy sources and energy performance, imposes the development of new solutions through which the existing district heating systems may be adapted to use renewable energy sources. The solar-thermal systems that are used on a large (district) scale are becoming more and more efficient from the point of view of their feasibility; however, it is almost impossible to create systems that should satisfy the thermal energy demand throughout the four seasons of the year. The hybrid solar-biomass system is becoming the applicable solution for the majority of the communities that have from this potential, since it can secure independence from the point of view of the use of thermal energy. This paper presents the design stages for the implementation of the hybrid solar-biomass systems with a view to identifying the optimal solutions for systems to be integrated into an existing district heating system. A case study (Taberei District in Odorheiu Secuiesc City), which provides a detailed description of the feasible technical solutions, is presented.

Poland has great potential for the development of renewable energy sources. The implementation of support systems dedicated to renewable sources has resulted in the installation of over 10,500 MW of installed capacity. At present, with high electricity prices, stimulated by the costs of CO2 emissions and the costs of fuel purchase, renewable energy sources are of particular importance in the transformation of the Polish power industry. The RES auction system and the My Electricity Program contributed to the growth of entrepreneurship and the development of the economy. Energy consumers, from passive ones, have become active market participants—prosumers. The RES auction system alone contributed to the creation of approx. 5 GWp of installed capacity of photovoltaics (PV) sources in 2016–2021, while the My Electricity Program contributed to the creation of approx. 2 GWp of installed capacity in PV installations in 2019–2021. The aim of the study is to compare the economic and social costs of two photovoltaic development programs, My Electricity and the RES auction system, from the point of view of the country (in support distribution costs—subsidies) and investors, renewable energy installations operators and prosumers to which these programs are targeted, namely, individuals and enterprises.

Renewable energy technologies are increasingly integrated into the modernization of multi-apartment buildings, however their benefits are rarely assessed from a complex environmental, energy and economic point of view. The article presents the results of the modernization of a particular apartment building in terms of the production and consumption of energy in a building, from the viewpoint of the life cycle. The benefits of the building’s energy modernization were assessed by introducing active (heat pumps and solar collectors for hot domestic water production) and passive modernization measures. The results show that the integration of heat pumps when electricity is produced from non-renewable energy sources according to the analyzed categories of life cycle analysis is not eco-friendly.

The exploitation of renewable energy sources has assumed a significant role, especially in an integrated vision of problems concerning energy policies, The 2009/28/EC Directive of the European Parliament and Council has indicated ambitious energy and climate change objectives for 2020 (according to the so-called “EU2020 Strategy”): greenhouse gas emissions reduction for 20%, renewable energy increase for 20%, improvement in energy efficiency for 20%. The aim of this paper is to present a GIS based methodology able to support decision-making in energy supply from Renewable Energy Sources (RES), focusing on two specific case-studies: Photovoltaic (PV) and Wind energy. To decide what type of renewable energy font is the best choice for a specific territory, it's important to know the local energetic situation, exploring the potential renewable energy sources available in that specific area, deciding what is the territory more compatible/sustainable among them, and if it's exploitable by suitable environmental and economic point of view. The methodology is largely directed towards the development of a tool to support siting decision.

Abstract The aim of this research is to find a solution that can contribute to the more widespread use of electric vehicles and, through development, promote the use of renewable energy sources. It aims to eliminate the disadvantages of electric vehicles, such as self-discharge, stationary charging and limited range. The focus is mainly a solar-powered solution, since small solar cells have already been implemented on the commercially available Nissan Leaf model to solve similar problems but with very little or no improvement. Encouraged by this attempt I have engineered a larger, more useful auxiliary solar cell system to improve the range of these vehicles.

The article deals with the economic evaluation of investment and optimization of the renewable energy sources for family houses. For example, from the point of view of solar systems, the optimal solution is based on the specific application of it. The design is dependent on the location of the panels and ration between active aperture area and real daytime consumption. Common calculations according to actual standards often give overstated results, which also reflected in the value of the investments. The article shows the research of optimal parameters of the thermal solar system for preparing of domestic hot water. A combination of related standards and software TRNSYS are used to find optimal parameters. Thanks to created and verified simulation models, it is possible to design parameters so as to avoid under-dimensioning or over-dimensioning of the each system. Energy price is another factor affects the payback period of investments. This is affected by the used energy sources and their combination. For example, buildings that use electricity to heat water or heating have different energy charges than a building that uses natural gas. So, the aim is to find optimal solution of the combination of renewable energy sources.
