Solar or solar energy can be an alternative source of energy in the future, where solar energy can be converted into electrical energy by utilizing the photoelectric effect that occurs in photovoltaic components or solar cells.  Solar cells or photovoltaic components can convert sunlight into electrical energy that can be used directly by the load or stored in a battery, a kind of electrochemical device that can store electrical charges in the form of chemical energy. The electrical energy generated by the solar cell is influenced by the intensity of light received by the sun. To gain the desired power and voltage, the solar cells are connected in series and parallel into a solar cell module. 2N3055 & MJ2955 transistor based solar panels are the basic materials for designing alternative power generation. In the process of manufacture, this solar panel utilizes the components of used components that are still feasible to use, so it can be used to be the appropriate technology to produce a solar panel that utilizes solar energy in the form of sunlight and solar heat. In this study also conducted experiments using glass components as a reflection effect from light sources. The result of this experiment obtained that the amount of electrical energy output resulting from the reflection effect of light by using 2N3055 transistor and MJ2955 transistor can produce increased current and increase electrical power.Keywords: Solar cell, Transistor 2N3055 & MJ2955, The effect of reflection light

Fishing Boat

This article aim to be able to take advantage of an electric motor as a net puller on a fishing boat using solar energy. The use of human labor as a net puller requires a large amount of energy and needs a break to be able to do more withdrawal activities, so the number of withdrawals that can be done is very limited. Pantai Jaya fishing groups as partners are among the 20 active fishing groups in the Pasie Nan Tigo sub-district of Koto Tangah subdistrict of Padang City who experience these problems. The problem of this partner can be given a solution in the form of the use of an electric motor as a towing net on a fishing boat. In order not to cause problems in terms of electricity supply, solar energy can be used by using solar cells, so there is no addition of fuel oil. The implementation method given is direct installation and provision of extension materials on the use of solar cell technology and the introduction of components and hand tools. This activity was carried out for two days which included preparation, installation and training, followed by a group of fishermen. The fishing group received a set of solar cells, electric motors, batteries and other accessories and installed them. Based on tests that have been carried out in sunny weather conditions at 300C, a load of 50 kg with a rated voltage at that time 12.4V, motor speed 2.7m / min, 2.4A. Based on the results of these tests indicate that the solar cell system has worked according to the parameters it should. Therefore, it can be said that this activity has been carried out properly and the solar cell system is functioning properly. Participants hope for these activities to be carried out for the following year, because there are still a number of fishing boat groups that are in dire need.

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.

Currently, the world has a lot of research and practical application of intelligent building systems integrated with intelligent power systems. Because Vietnam is a country with potential for solar energy, the integrator of solar energy is being strongly developed. However, the research result of the optimization of electrical energy used by the intelligent type solar integration is rare. This paper presents the design and structure of the module of intelligent control and monitoring via wireless network integrated with the automatic solar concentration system. The system allows easy connection and operation of all electrical power sources including the dispersal solar power to ensure the efficient and lower power consumption. In addition, the solar cell system is applied the Maximum Power Point Tracking technique (MPPT), which helps to stabilize and improve the power generation efficiency of the PV panels. The test results on the module showed absorption performance of automatic solar-cell flat plate systems is raised by 20-30% and power consumption in small households reduced approximately 30%.
