Improve the Efficiency of the Photovoltaic System by Controlling the Incident Solar Radiation
The main objectives of this paper are to identify and implement the basic steps in building a photovoltaic (PV) field. Starting with the identification of the location where PV panels will be installed and the calculation of the level of solar irradiation in that specific region, a specific algorithm can be used to analyze the real energy generated by the PV system. This paper aims to identify a simple solution to increase the real energy generated by the PV systems on the hypothesis of using semi fixed panels, mentioning that the number of panels mounted on a fixed surface is smaller if the angle of inclination of the panels is changed twice a year because the panels that are going to be installed are resulted from the calculation of inclination angle maintained during winter when the length of the shadow of the panel is higher than in summer, resulting in a higher distance between rows of the photovoltaic panels. Although the number of installed panels is smaller with the alternating inclination angle than the fixed inclination angle solution, the real energy obtained exceeds 20 [%] which could mean an earlier return of the investment in photovoltaic panels.
Energy demand in India increasing as population growth increasing but it is difficult to fulfill energy demand as the resources are limited. India has a significant capacity for solar energy generation from renewable energy sources-solar photovoltaic, solar thermal, small water, wind, biomass, biofuels, and others. While proven technologies have emerged over the last few decades, the economic practicality of renewable energy is yet to be achieved and requires creation and adoption of innovative business and financial models. India's energy problems include: Over 40 per cent of the households in India still don't have electricity. One third of our total energy availability is from non-commercial sources (organic manure and fertilizer). Per capita energy consumption is one third of the world's average and per capita electricity consumption. India faces a supply gap of about 11% shortage and 14% of peak power shortage supply demand. Solar energy is at forefront of clean, renewable energy, and this pace is increasing due to the progress in solar panels production and efficiency as well as rapid unstable fuel costs. Photovoltaic (PV) solar cells are the most easily achievable solar technology, and they work best in bright days, in which the event does not have little or an obstacle in the sunlight. Photovoltaic (PV) technologies convert energy into electricity directly from the sunlight. Sunlight semiconductor strikes the substance and produces electrons, releasing electrons from their nuclear bonds. PV panels have no moving parts and usually live with less maintenance for twenty years or more. Landlords can set up PV panels to reduce or eliminate their monthly electricity bill, and utilities can create large "farms" of PV panels to provide pollution-free electricity to their customers. When the sun is at its highest point in the sky, then the power generation can offset the costly electricity generated when daily demand is greatest. Concentrated photovoltaic technology (CPV) uses optics such as mirrors and lenses to focus on sunlight on solar cells to generate electricity. CPV benefits on photovoltaic concentration because it is the number of solar cells required for the same power generation. With the duration and intensity of the sunlight, the temperature also puts a big impact on the performance of the PV module because high temperature reduces production efficiency. This experiment tells a practical approach to increase the efficiency of the solar panel by the number of uses of the mirror mechanism. These reflectors are cheap, easy to use, quite simple to use and no additional equipment or device is required to use. But experimental results show a remarkable increase in the overall production of solar panel. Experimental readings received from (a) without reflectors, (b) with one reflector, (c) with two reflectors and (d) with three reflectors) with numbers of reflectors are compared.

PAPER TITLE: IMPROVEMENT OF EFFICIENCY OF SOLAR PANEL USING DIFFERENT METHODS
The recent upsurge in the demand of PV systems is due to the fact that they produce electric power without hampering the environment by directly converting the solar radiation into electric power. Solar energy is completely natural, it is considered a clean energy source. So the study on improving the efficiency of solar panel is very necessary In this paper I have discuss various methods of efficiency improvement of solar panel. We can improve efficiency of solar panel by using solar tracker with panel which continuously tracks sunlight throughout the day to get maximum solar energy. Second method to improve the efficiency is dust cleaning. Dust is barrier between sunlight and solar panel. Third method is cooling technique. As panel temperature increases output voltage of solar panel decreases so cooling of panel is necessary for improvement of efficiency. Other method is anti-reflecting coating for solar panel, which improve efficiency of panel. Aim of this paper is to increase the efficiency and power output of the solar panel.

Improving the performance of the photovoltaic panels
There are many factors that affect the performance of photovoltaic (PV) panels, e.g. (i) dust accumulation on PV panels, and (ii) overheating of the panels. Dust accumulation on PV panels, especially in desert areas, can obscure the solar radiation, and therefore reduce the efficiency of the panels dramatically, as well as heating of PV panels due to excessive solar radiation and high ambient temperature reduces the efficiency of the panels, significantly. Many studies have been carried out to solve dust deposition and overheating of solar panels separately, however, none of them was done to solve both problems at the same time. The main objective of this research is to solve the problems of dust accumulation and overheating of PV panels at the same time using the minimum amount of water and energy. These two issues, i.e. dust accumulation and overheating, are tackled by developing a system that can clean the PV panels from deposited dust, and at the same time cools the panels. The ...
Enhancement of power generated by solar panels using reflected sunlight
IRJET, 2022
The enhancement of energy generated using solar photovoltaic panels in a limited space is important in urban areas due to increased land cost in the recent years. Although there exist different procedures, technologies and methodologies to focus the sunlight on solar panels, we have suggested a new approach to enhance the energy generation from the photovoltaic panels, i.e., by keeping two solar panels facing each other to make use of the sunlight reflected off panels. Furthermore, inclusion of a self-cleaning technology for solar panel setup can promote efficiency in terms of electricity produced, reduce manual maintenance required and protect the solar cell.

Photovoltaic Module Efficiency Optimizing Techniques: A Review
Journal of Applied and Emerging Sciences, 2021
The solar irradiation falling on PV-module that converted into heat hence the reducing efficiency. The dust deposition decreases efficiency and resist the amount of solar radiation interacting on surface of PV-panel. The mismatch position placed of PV string can make the mutual shading between the PV-Module, Due to this reason of shading the totally efficiency of PV system falls. To overcome all mentioned problem, in this paper the review of environmental factor and their latest minimizing techniques for optimizing performance of PV-Module is discussed. This paper merely focused on the review of cooling, Cleaning and shading effect techniques.
A conventional solar photovoltaic cell has a drop in electrical efficiency as the day passes by. This is due to the fact that the efficiency largely depends on the operating temperature. The surface temperature of the photovoltaic cell is inversely proportional to the electrical efficiency. As a consequence of this phenomenon, the efficiency of the solar panel is approximately in the range of 15-16% and it gradually decreases further when the day passes. To eliminate this drawback there are two methodologies employed in this research work:
