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.

Smart Traffic

The objective of this project is to control the traffic signal with help of solar energy. This project has been developed as a model of Traffic light controller. The signals can be controlled through software programs and can be varied depending upon the location. For example some places needs green signal to glow for long time. And some directions need red signals to glow for long time. This can be achieved simply by varying the delay in the software. Solar power is used to provide the power to the solar lights. So this project is very useful to the government to save the power.The solar panel is solar photovoltaic modules use solar cells to convert light from the sun into electricity. Now-a-days, instead of using the power from the supply line for various operations, most of them are going for solar energy source, as it is cheapest.

There are eight columns in the Periodic Table. The eighth column is comprised of the rare gases, so-called because they are the rarest elements on earth. They are also called the inert or noble gases because, like nobility, they do no work. They are colorless, odorless, invisible gases which do not react with anything, and were thought to be unimportant until the early 1960s. Starting in that era, David Fisher has spent roughly fifty years doing research on these gases, publishing nearly a hundred papers in the scientific journals, applying them to problems in geophysics and cosmochemistry, and learning how other scientists have utilized them to change our ideas about the universe, the sun, and our own planet. Much Ado about (Practically) Nothing will cover this spectrum of ideas, interspersed with the author's own work which will serve to introduce each gas and the important work others have done with them. The rare gases have participated in a wide range of scientific advances-even revolutions-but no book has ever recorded the entire story. Fisher will range from the intricacies of the atomic nucleus and the tiniest of elementary particles, the neutrino, to the energy source of the stars; from the age of the earth to its future energies; from life on Mars to cancer here on earth. A whole panoply that has never before been told as an entity.

The Difference

People can make solar energy alternative energy by employing solar panels to generate electricity. The utilization of solar energy on a solar panel to generate electricity is affected by the weather and the duration of the radiation, and they will affect the solar panel’s temperature. There are various types of solar panels that can be found on the market today, including Mono-Crystalline and Poly-Crystalline. The difference in the material used needs to be observed in terms of temperature changes in the solar module. Our study’s findings showed that a change in the temperature would impact the solar panel’s output voltage, and the solar panel’s output voltage would change when it was connected to the load although the measured temperatures were almost the same.

In the present study, performance analyses of a solar module are made through the optimal variation of solar tilt angle, pertaining to the maximum generation of solar energy. The work has been carried out for a particular location at Tripura, in India, considering three different cases on an annual basis. An intelligent behavioural based algorithm, known as artificial bee algorithm (ABC), has been implemented for finding the optimal orientation of solar angle in analysing the performance. The result shows marginal differences are obtained in producing yearly maximum solar energy for different orientations of the PV module. It has been observed that the maximum average solar energy is obtained for the case where continuous adjustment is made by rotating the plane about the horizontal east-west axis within 20° to 30° tilt angle. The computed maximum and minimum of the monthly average efficiency is 10.9% and 8.7%, respectively. Further, a comparative study has been performed in generating average solar energy through optimal tilt angle by the implementation of Perturb & Observe method (P&O). The monthly average solar power computed by P&O method resulted better in a range of 2% to 15% in comparison to that obtained by ABC. While on the other hand, the efficiency computed by ABC algorithm was 15% to 19% better than that evaluated by P&O method for all the cases studied in the present work.
