Investigative analysis of the influence of diverse fin configurations on the performance of a dual pass solar air collector

This study conducts a thorough investigation into the thermal performance of the double pass solar air collector, with a specific focus on the effects of three distinct fin configurations: parallel, vertical, and opposed. It is significant as it delves into the realm of solar air heating efficiency, a critical component in the broader application of solar energy technologies. Utilizing the geometric details and experimental findings, this study broadens its scope by examining a range of mass flow rates, specifically 0.0036 kg/s, 0.0110 kg/s, 0.0146 kg/s, and 0.0183 kg/s. Such an approach allows for a comprehensive understanding of the double pass solar air collector’s performance across diverse operational scenarios. The methodology is Computational Fluid Dynamics, which facilitates an in-depth analysis of temperature and velocity contours in both XY and YZ planes of the double pass solar air collector. The results of this study indicate that the parallel fin configuration significantly enhances heat transfer, evidenced by notable temperature increases, especially at the lower end of the mass flow rate spectrum. Conversely, while vertical and opposed fins result in greater pressure drops, they do not proportionally increase the temperature in a similar manner to parallel fins. The study concludes with a strong recommendation for the incorporation of parallel fins in future double pass solar air collector designs, particularly in situations where lower mass flow rates are predominant. This study contributes significantly to both the theoretical and practical aspects of solar collector efficiency, offering valuable insights for the development of more effective solar heating solutions.

Investigation of conical passive solar still by incorporating energy metrics, efficiency, and sensitivity analyses for sustainable solar distillation

The application of solar energy technology to solve the freshwater scarcity problem of society will contribute to the sustainable development goal of the United Nations. It will also recede the dependency on fossil fuels. This paper deals with the investigation of conical passive solar still (CPSS) by incorporating energy metrics, efficiency, and sensitivity analyses. Fundamental equations have been obtained from the thermal modelling of CPSS followed by experimental validation. The coefficient of correlation for water temperature is about 0.96, for condensing surface temperature is about 0.99 and for freshwater yield is also 0.99. The present work involves diverse monthly weather conditions for the performance analysis of CPSS. In the present work, a MATLAB-based computational code is used to compute hourly freshwater output, exergy, and energy assessment for their yearly results. Afterward, energy metrics and different efficiencies were computed, and the outcomes were compared with recent investigations. Finally, the energy payback time has been lowered by 161.40%. The energy production factor and life cycle conversion efficiency for CPSS were improved by 61.71% and 28.20%, respectively, compared with the conventional solar still. The comparative study of daily thermal efficiency reveals that the efficiency of CPSS is higher by 51.47% than V-type solar still.

Structural design of solar car body based on solid mechanics analysis of solar panel surface

With the increasingly serious problem of global warming and the growing scarcity of energy represented by oil, automobile development has reached a historical tipping point. Nowadays, the most popular solution is to use other clean and sustainable energy to replace current oil and natural gas, thereby addressing both environmental and energy shortage issues. Solar energy, as a "inexhaustible" source of energy, has made significant technological advances over the course of human history. There is, however, a gap in the application of solar energy technology in automotive technology. This paper uses COMSOL software to model the most commonly used solar panels and simulates and studies the streamline distribution, velocity distribution, pressure distribution, and stress distribution of the solar surface under high-speed movement of 90km/h. SoildWorks simulation is used to design a vehicle body structure for future solar cars based on these data. FLUENT software is used to simulate and study the streamline distribution and pressure distribution of the car body at a high speed of 90km/h. Finally, the design's logic and feasibility are validated. The fluids on the surface of a single solar panel and a vehicle body are simulated in this paper. Testing the pressure distribution and stress and strain tests can reveal the rationality and feasibility of the structural design.

Project of Building: Solar Hot Water

The rapid development of urbanization in China has led to an increase in high-rise residential buildings, leading to a surge in the construction industry. However, this prosperity has brought about a significant increase in energy consumption, prompting people's demand for alternative energy. As a solution to this problem, solar hot water systems are becoming increasingly popular in China. The following contents need to be considered in the design of solar hot water systems. The general solar hot water system consists of solar collectors, solar water distribution pipes and water storage tanks. The arrangement of the water storage tank and the water distribution pipe is matched with the design of the building, which has great influence on the operation of the solar energy in the building. With the rapid increase in building height and the increase in residents, the roof area has not changed. The architectural layout will have an impact on the absorption performance of solar radiation. Therefore, in order to optimize the use of solar energy, regional planning should be considered. Different solar radiant intensity and different locations of solar collectors will lead to different collection efficiency and hot water supply conditions of solar water heating systems. Throughout the entire process of architectural design, the application of solar energy technology in buildings also requires consideration of the operating area conditions and architectural style, in harmony with the architectural style.

The Implementation of Conservation Policy and the Application of Solar Energy Technology in Small House Areas: Stockholm, Sweden

ABSTRACT This paper investigates the dynamic between protection of the historic environment and the application of solar energy technology on 1- or 2-family houses in Sweden. More specifically, the building code relating to the installation of photovoltaic (PV) panels on house roofs and how existing policies are implemented in Stockholm City is investigated in order to better understand the challenges in reconciling renewables and the conservation of built heritage. Especially when applied in urban areas PV panels may have a large impact on socio-cultural values, making them difficult to insta where the historic environment is to be protected from large changes. By using a mix of methods (policy analysis, case studies, and interviews) we come to the conclusion that municipalities should develop routines and guidelines that offer homeowners precise information on the potential of solar energy and requirements motivated by concern for the historic environment. Guidelines that are well-known, clear and also require homeowners to dismount exhausted panels could work both to protect built heritage and to promote more use of solar energy in some small house areas.

Application of Solar Energy Technology in Green Healthcare Camps for Fighting COVID-19 Outbreak in Saudi Arabia

The healthcare facilities sector is an energy-intensive organization especially at a time of spreading dangerous infectious viruses, such as new Coronavirus, or what is known as COVID-19. Recently, many countries have opened several mobile field quarantine hospitals provided with the required technical equipment to prevent the COVID-19 outbreak in these countries. Unfortunately, most of these healthcare camps are lacking in the application of the necessary sustainability principles and health standards to become green healthcare facilities. Solar energy can be used for various purposes in green healthcare facilities, such as power generation and other sterilized applications. Therefore, in the present paper, a new design for the mobile, quick built, and solar-powered green healthcare camp, in safe and effective 24 hours a day services, is introduced. The proposed green healthcare camp is built using modern building technologies for rapid constructions, in which the building design is proposed to incorporate the photovoltaic power generation consideration. Photovoltaic systems are designed according to the loads required for the operation of the designed model of the green healthcare camp. Moreover, the total cost of a solar-powered green healthcare camp is estimated according to local conditions and standards in Saudi Arabia. The practical recommendations are presented with the designed photovoltaic system to attain the overcurrent and overvoltage protection. The photovoltaic designed system is proposed under the condition of ascertaining the service continuity of the photovoltaic power system during the electric faults in the photovoltaic strings. This is achieved by incorporating series diodes at the terminals of each photovoltaic string. The performance of a 50-kW PV system simulated using Matlab/Simulink is evaluated for the fault disturbance to enhance the service continuity.

A study on China's economic growth, green energy technology, and carbon emissions based on the Kuznets curve (EKC).

China's rapid economic development is unavoidably characterized by environmental pitfalls, especially the carbon dioxide emissions of greenhouse gases from the use of energy. Since there is a relationship between economic growth, energy consumption, and carbon emission, it is important to note that the continuous improvement and application of solar energy technology will play an active role in carbon emission reduction. Therefore, this paper uses the Kuznets curve to probe the relationship between economic growth, solar energy technology, and carbon emissions. The results show that solar energy technology, economic development level, and carbon emissions are all integrated at the second order with a long-run cointegration relationship. In the long-run, the relationship between economic growth and carbon emissions is inverted "U," which suggest that there is a turning point of carbon emissions, where the carbon emissions first increase with economic growth and then gradually decrease, which is reflected in the image as an inverted "U" curve. Also, the impact of economic factors on carbon emissions and the innovation of solar technology can negatively influence carbon emissions, and enhancing the innovation of solar technology has a positive effect on reducing carbon dioxide emissions.

Assessment of solar energy technologies in Africa-opportunities and challenges in meeting the 2030 agenda and sustainable development goals

Renewable energy sources like solar energy have an important role to play towards the implementation of the 2030 agenda and Sustainable Development Goals (SDGs) in Africa. While renewable energy was not stated as one of the technologies for the achievement of the Millennium Development Goals (MDGs), it played an indirect role towards meeting MDG targets especially in the areas such as household application, health, education and poverty reduction in Africa. However, renewable energy's impacts (including solar energy technologies) were not quantified, and lack of performance assessment could be in part attributed to the weak implementation of solar energy projects in the developing world including countries in Africa. The aim of this paper is to conduct meta-analysis of the literature on the performance of solar energy technologies in order to determine solar energy adoption trends in African countries. This is supplemented with expert interviews and data gathered from the World Bank/Global Environment Facility. Using three case studies of Ghana, Kenya and South Africa, this paper examines the benefits and challenges that are associated with the application of solar energy technologies for meeting SDGs in Africa. Finally, the paper concludes by highlighting the policy implication for the application of solar energy technologies.

Exploitation of solar energy in Cyprus

This paper reviews the application of solar energy technology in Cyprus and presents an energy analysis with emphasis on the contribution of solar energy to the energy consumption in the island. The almost full reliance of Cyprus on imported oil to meet its energy demand, together with the abundance of solar radiation and a good technological base, created favourable conditions for the exploitation and development of solar energy in the island. Cyprys began manufacturing solar water heaters in the early 1960s and today it produces more than 30,000 m 2 of solar collectors yearly. It is estimated that more than 130,000 solar water heaters are in operation providing the equivalent of 9% of the total electricity consumption in the country; this corresponds to, approximately, 4% of the national energy consumption. However, the use of solar energy for space heating and cooling provides a further challenge, because it does not appear to be economic under the climatic conditions and system design practices currently prevailing in Cyprus. The paper provides a statistical analysis of the energy demand and identifies areas of further growth for solar energy technology.
