Solar Photovoltaic System

Renewable energy sources are becoming important for the production of electricity used in residential, commercial and industrial applications. These resources include nonconventional sources like solar, wind, hydro, biogas, tidal and biomass. All these are contributing in the production of electrical energy and also help in reducing the pollution by reducing the green gas emissions which were one of the reasons to reduce the use of conventional sources. Out of all of the above, the source which is gaining an importance and maximum usage is a solar energy. The reason behind its extensive use is it is freely available, abundant, non-pollutingin nature and its conversion without involving any rotating device. Combining the two systems increases the performance and efficiency of a particular system. Hence to improve its performance and use by two-fold, a solar system can be integrated with thermal, hydro or wind power system. Also, a suitable converter topology will be used along with an appropriate control algorithm. Solar energy changes as per irradiance and temperature in a day also one factor which reduces the power output is the partial shedding in cells. This will alleviate the conversion efficiency of solar system (About 20%). Many conventional and advanced algorithms are used for getting the optimum output from a solar system. Now days to get optimum energy from a solar system, soft computing algorithms are used in a system which are called as operating point tracking algorithms. This paper intended to emphasize on converter topologies and a brief introduction of MPPT algorithms

An experimental study has been carried out to reduce the costs of freezing products from artisanal fishing in Peru using a photovoltaic solar system. The refrigeration chamber and the photovoltaic system have been equipped with electrical sensors to determine the cooling efficiency and thus calculate the savings. The results indicate that it is possible to reduce costs up to 45% using photovoltaic solar energy. The target users of this technology are artisanal fishermen in Peru. Using photovoltaic energy for freezing would allow them to add value to their products and improve their selling price. In this way, fish commercialization can be performed in better sanitary conditions and at fair prices.

The need for electrical energy continues to increase every time. Concerns about the depletion of fossil energy reserves encourage the acceleration of the development of renewable energy use. One of renewable energy is the solar energy. Due to the irreversible irradiation conditions, it takes controls to keep the solar panel's maximum power. The most widely in Maximum Power Point Tracking (MMPT) is Perturb Algorithm and Observe (P&O) but P&O Algorithm has deficiency of oscillations when steady state and MPP trace errors when irradiation changes rapidly. In this paper proposed P & O-Fuzzy algorithm is a modification of conventional P & O to improve the efficiency of solar panels. This research uses Matlab for simulation and hardware implementation using microcontroller Arduino Uno and buck converter topology. The result of simulation and hardware implementation, conventional P & O has an average efficiency of 85.03% while MPPT modification with P & O-Fuzzy algorithm can improve MPP tracking efficiency with 89.67%.

Energy Storage Systems

In the presented work, the possibility of using photovoltaic silicon panels with a double-sided arrangement of solar cells on the front and back sides is presented. With a lack of space for placing solar panels, these types of modules can significantly increase the generation of electrical energy. Equipping photovoltaic systems with rechargeable batteries contributes to a more rational consumption of electrical energy, while energy storage systems significantly increase the efficiency of solar generating systems. The proposed designs are intended to increase the power characteristics of solar energy converters in the winter months, in the presence of snow or when using reflective surfaces on road surfaces. The results of the experimental studies have shown a significant efficiency of the proposed designs, as well as an increase in the total generation of electrical energy. With the development of the global technical potential and a significant increase in the production of power plants for solar energy, a new opportunity has emerged to use combined solar plants for photovoltaic conversion of the flux of incident solar radiation. At the Department of Renewable Energy Sources and Electrical Systems and Networks at Sevastopol State University, at the site of the Institute of Nuclear Energy and Industry, a photovoltaic installation was developed and studied, consisting of two side silicon solar cells and energy storage systems. The article presents the results of experimental and theoretical studies, presents diagrams, drawings and graphs of various characteristics of the FSM-110D photovoltaic panel and storage batteries. The research results show the increased efficiency of the proposed installation, as well as a good possibility of using the presented photovoltaic systems to provide them with autonomous and individual consumers living in the Crimean region and the city of Sevastopol.

The Cost

It is becoming increasingly important to include information about power generation from renewable energy sources in the training of electrical engineers. Solar energy is arguably the most common renewable energy source in use today. Providing practical hands-on training on solar energy power generation today requires the use of photovoltaic panel devices which are used for transforming solar energy into electrical energy. In many developing countries, practical hands-on training on solar power generation is limited due to the cost of photovoltaic panel devices and so the training consists of theoretical and tutorial classes sometimes supported by remote and virtual laboratories. This paper presents an augmented virtuality tool where real-time information from a mobile device’s sensors is used directly within a virtual or computer generated environment. The tool provides a practical context for hands-on tutorial exercises on solar energy power generation.
