The output power of the solar photovoltaic panel decreases as the operating temperature increases. The use of photovoltaic/photothermal (PV/T) collectors not only effectively cools the operating temperature of the battery, increases photovoltaic power, but also produces hot water. Therefore, the PV/T collector improves the annual utilization efficiency of solar energy, and can meet the user's demand for different energies. This paper builds an experimental platform to compare the PV/T collector photovoltaic/photothermal performance and experimental comparison with traditional PV. The results show that the PV/T collector has a thermal efficiency of 31.5% and a photovoltaic efficiency of 17.82% at a flow rate of 0.023 Kg/s to achieve high efficiency in solar energy utilization.

According to the concern of WHO the less association of people in an office may restrict the likelihood of spreading this COVID-19 infection. And it applies to all kinds of organizations. On the other hand, the pharmaceutical companies are working hard to maintain uninterrupted production of vaccine and medicines. This paper focuses on the main layer which is the power system management and its utilization through the less involvement of any individual. Automation and controlling the system remotely can be a good solution. In the design process the FDA proposed structure for the Pharmaceuticals needs to be maintained as well. One of the significant necessities is most of the energy should come from environment friendly system and in Bangladesh sunlight-based energy is the best solution right now. Solar energy utilization efficiency can be increased using the data logging system and machine learning algorithms from that archived data. In this paper, a SCADA operated Off-Grid Solar PV Automation System has been proposed to increase the utilization efficiency. To predict solar power availability over time and perform efficient energy trafficking, the automation system will analyze previous data and perform situational awareness operations for uninterrupted solar power generation. The proposed automation system has been designed focusing on pharmaceutical manufacturing utilities. A comprehensive analysis of the proposed automation system for pharmaceuticals industry applications has also been presented in this paper. The continuous monitoring system for this Off-Grid Solar PV power generating unit preserves multiple data entries, which increases with time and subjected to energy trafficking. And this energy trafficking based on machine learning increases the overall solar energy utilization efficiency.

The energy is one of the most important needs of the humanity. One of its biggest challenge or danger is that the world's demand for energy continues to grow. The aim of present study is to review the introduction of solar energy utilization, the economic determination of the return of crystalline solar photovoltaic systems in Hungary, the electricity price reductions for individuals and the change in the payback period. The effect of the changing investment cost to the payback period based on the changes in electricity price reductions and in central bank interest rate is written in this study. An important question is for a household: decide by or against a solar (PV) system. The main direction of our recent research is the utilization of photovoltaic (PV) solar energy with crystalline solar systems. The research was carried out in solar-electric power plants extended from 1.5 kWp to 10 kWp. The calculation of payback time was performed by dynamic indices.

Abstract In this paper, a new design of a solar still powered by a compound parabolic concentrator (CPC-SS) for agriculture irrigation is proposed and investigated. The concentrating performance of its concentrator is simulated which is proved that it has a wide focusing angle and the receiving rate is still more than 80% when the incident angle of light reaches to 35 deg. Theoretical calculations show that the daily water production rate per unit area of the solar still can reach 4 kg/m2, which can meet the crop growth needs of 2 m2. The water production performance and operating temperature of the CPC-SS were tested experimentally under actual weather conditions, and the variation curves of system internal working temperature and water production performance with time were given. As the results, in the sunny weather conditions in Beijing in the autumn, the daily water production of the tubular solar still is about 2.03 kg/m2, and the maximum operating temperature in the tube reaches 60 °C. The actual solar energy utilization efficiency can be as high as 22%.

To solve the problem of rapid development of domestic water tourism and water pollution in scenic waters, windsurfing technology and solar photovoltaic technology are applied to small and medium-sized sightseeing cruise ships. While optimizing the hull design and component coordination, the application of automatic control technology further improves the utilization efficiency of wind and light energy, and achieves the adaptation of the sail angle of attack and the efficient coupling of the two energies. The ship mainly uses the natural resources of solar energy and wind energy. It will not burn fossil fuels during the ship’s travel, thus reducing the emission of toxic and harmful substances, which has positive significance for environmental protection. In short, the solar wind-assisted power generation ship studied in this project has remarkable features such as zero emission, high degree of intelligence, significant wind-assisted effect, high efficiency of light energy utilization, and low hull space occupation. Compared with the ordinary lake area cruise ship, the energy-saving and emission reduction effect of the power generation ship is very obvious[1].
