AbstractThe photovoltaic technologies have been developed year by year in different countries; however, there are some countries where this kind of energy is being born, such as the Brazilian case. In this paper, some important parameters are analysed and applied to different solar cell materials, identifying that if the fossil fuels were substituted by solar cells, it would reduce the CO2 emissions by 93.2%. In addition, it is shown that the efficiency of solar cells is not as farther as it could be thought from coal thermoelectrical plants in Brazil and the cost of energy using solar cells could be as good as these thermoelectrical plants. Finally, the potentiality of Brazilian territory to implant this technology is presented, identifying that with the use of 0.2% of the territory, the energy demand could be supplied.

In this paper a motorized solar energy collector system-a driver system that positioned the solar cell panel differently during day-time was design and implemented. The aim is to optimize the amount of solar energy that can be trapped from the sun using a solar cell panel. This is achieved by using a stepper motor, controlled by Atmel AT89C52 microcontroller, to align the panel such that all incident rays strike normal to the panel’s surface thereby maximizing the amount of solar energy that can be trapped from the sun. The alignment is time dependant. This model was implemented and tested and the results proved to be successful in maximizing the energy received from the sun than if the solar panel was fixed at a particular position.

Photovoltaics (PV-also called solar photovoltaic devices) are used to harness the power of the sun via the electronic process that occurs within semiconductor cells. The solar energy is absorbed by the cells, which causes the electrons to break away from their atoms, allowing them to flow within the material to produce electricity. This electricity will become the renewable energy for Kentucky, as the generation of coal will but come to a stop within the near future. Like Denmark who is running on 100% renewable generation we must stride to become fully operational on solar. In the present work, we systematically studied about renewable energy resources, in particular, solar energy for the application of photovoltaic panels in Eastern Kentucky. By analyzing data from our PV cells at Morehead State University designed to follow the direction of the sun for optimized output and by incorporating MPPT charge controllers, we have constructed a maximum power algorithm that performs best for the location. Utilizing these, measurements of daily electricity production in comparison to the average power needed for household use has validated our research. With the advancements in solar cell technology what was once impossible is now reality, as solar power can easily power this region based on our data. Knowing this, being a prime location we can now push to enable the advancement of renewable energy production and become less dependent on fossil fuels, thus creating an infrastructure that will run off solar power.

This paper deals with the influence of solar modules soiling on their energy efficiency. Soiling is the term used to describe the deposition of dust on solar modules. Dust, most often contains organic minerals and particles which result from the burning of fossil fuels, etc. In research studies investigating the influence of dust on the solar modules efficiency in the world, in the Solar Energy Laboratory at the Faculty of Sciences and Mathematics in Nis, and in the Solar Energy Laboratory at the Academy of Sciences and Arts of the Republic of Srpska, it was concluded that all types of dust negatively affect the energy efficiency of solar modules, with ash, limestone (calcium carbonate), red soil and sand (silicon dioxide) having the greatest impact.

Energy has important meaning in social and economics achievement to continously development and support to national economics activities. Energy consumption in Indonesia increases rapidly parallel with economics engagement and people growth. To supply energy requirement, renewable energy source should be developed. Renewable energy potency like solar energy hasn’t been used for big scale although Indonesia has big energy potency. Indonesia be included on tropical area which is exposed sun radiance almost year. It means solar energy has good prospects to be developed in Indonesia. Solar energy is one kind of energy which is gotten by converting sun calor energy to another type of energy. Solar energy can be used in form solar cell for electrical power plant. The utilization of solar cell can help people who lives on isolated area which is far from electrical network to use electrical energy.

Pollution and climate change due to the use of fossil fuel can no longer be denied, and this coupled with a waning supply of oil leads one to inevitably conclude that a clean, sustainable energy source is needed. That source is solar energy, the cleanest, safest, and most environmentally friendly energy source we have. In this paper, a photovoltaic (PV) solar energy system is used to generate electricity that will recharge a battery (DC 12V). The portable recharged battery will serve as the energy source for an electric vehicle. Moreover, in order to reduce manpower, a PC-based remote electrical monitoring technique used in the battery’s recharged system will be established via a TCP/IP network. Consequently, a PV solar panel with a 30 Watt capacity used to generate electricity using a PC-based monitoring system is exemplified.

Solar energy is often known by other terms solar energy is a form of renewable energy source. The potential of solar energy certainly affects the power generated in solar modules, there are several influences that cause solar energy not to be obtained optimally. In this study will be made mathematical modeling using multiple regression methods exposed to the angle of tilt and intensity of the sun with the research object of the polycristalline type solar module. The results obtained by calculating mathematically obtained the accuracy of the model with MAPE, as well as the adjusted value of R square of 0.960363563 which states that the percentage of the influence of irradiation-free variables and temperature simultaneously on the current obtained is very strong. While the results of calculations with double linear regression, the value of the regression coefficient on the irradiation variable (x_1) by 0.0000316, it means that if other variables remain and irradiation variables increase by 100 W/m2, then the current increases by 0.00316 A. Then the regression coefficient on the temperature variable (x_2) by 0.010573, this means if other variables remain and temperature variables increase by 1oC, then the current increases by 0.010573 A. From these results, it should be known the level of accuracy of the model which in this case uses MAPE. MAPE obtained on this model is 7.046%, this corresponds to the error standard of 0.007650294 with an average current measurement scale of ±0.1 A. Thus, the MAPE results show that the model has an accuracy of 92.954%, which means that the modeling obtained is very good.

Today, excessive consumption of fossil fuels in architecture, especially air terminals and with the increase in the number of terminals along with population growth, the energy shortage crisis in the not-so-distant future in this high-use structure predicted. Therefore, the present study aims was designing an air terminal using photovoltaic panels with an energy efficiency optimization approach. The most important energy efficiency of the sun is its direct conversion to electricity. One of the systems for direct conversion of energy from radiation to electrical energy is the photovoltaic system. Advantages of using photovoltaic panels have led to the growing use of these plates at various scales. In addition, the use of photovoltaic panels as structural elements in architecture has created innovations in the building industry and has given a new meaning to the architecture. The use of photovoltaics in terminals is a smart method to bring contemporary architecture to a new concept in green architecture. Finally, we can say that photovoltaic module has a double function in the terminal; that is, photovoltaic module also replaces conventional building materials and they produce electricity. By replacing photovoltaics, cost of materials is deducted from the total cost of the building and the cost of the photovoltaic acquisition is partially offset. Such as the integration of photovoltaics with the roof which is the best way to get the maximum efficiency of the system in which the sun is perpendicular to it.
