Evaluating the Most Effective Solar Panel by ENTROPY and COPRAS Methods

Introduction

Due to continued industrial expansion, the decline of fossil fuels, and increased environmental awareness, the need for renewable energy sources has risen steadily this century. The sun is the renewable source of all life on Earth. Through fusing H₂ into He at its core, this inexhaustible source radiates energy and supplies with both light and heat. This known as solar irradiation. Only approximately half of the sun's energy reaches the surface of Earth. The rest is either reflected or absorbed through the atmosphere and clouds. Even so, the sun provides enough energy to meet the needs of the whole human race — millions of times over. Solar energy is one of the options to petroleum-based fuels for producing power in tandem with today's quickly expanding industries. It is the cleanest and the most significant power resource that it can be utilized in almost every area. The first of these areas is lighting systems. Solar energy or sunlight, can be utilized directly for lighting and heating businesses and homes, for hot water heating, and for producing electricity, cooling with sun, and a range of other industrial and commercial uses. The fact that electricity production by sun is an excellent option to electricity generated from fossil fuels, with no water and air pollution, no global pollution by warming, threats to public health, and no electricity price spikes’ risk, is especially significant. The amount of solar energy available is immense. The quantity of sunshine that touches the earth's surface in an hour and a half is adequate to power the entire world's energy usage for a year, according to the United States Department of Energy. The amount of energy contained in all of the world's natural gas, coal, and oil reserves is equal to sunshine’s eighteen days on Earth.

Once a system is in location to use the sun source and convert it into beneficial power is free. Since 2010, the mean price of photovoltaic panels has decreased by more than 60 percent, while the solar electricity system’s cost has decreased through roughly 50 percent. The solar electric is regarded to be cost-competitive with other forms of energy now. Without considering the given installation’ specifics, there are solar energy industries’ 2 primary kinds: concentrating and photovoltaic solar energy. When the solar irradiances are come on one of photovoltaic panels, photons from the sun are adsorbed through the solar cells, causing an electricity area to form across the sheets and energy to flow. Photovoltaic panels can be installed on the ground, on the roof, or on the wall. They can be permanently oriented to maximize output and value. In the same way, they can be mounted on trackers that follow the sun across the sky. In the future, our capacity to use solar and other sustainable energy resources is clearly dependent on our ability to do so. The tax incentives, expanding technologies, and utility firms adjusting to solar users are all positive signs in the solar energy business. The most significant thing to remember is that one m² collects 4.2 kWh of energy from the sun every day, which is about equivalent to nearly a barrel of oil per year when averaged over the entire surface of the earth. The key conditions for operating and developing an efficient solar energy station are: Right site (favorable climate and available land), right equipment choice (such as panels, inverters), and solar power availability (preferably direct sunlight unobstructed). Photovoltaic panels are one of the most expensive pieces of equipment due to their manufacture and installation expenses among used equipment.

In this reason, a photovoltaic panel is photovoltaic system’s significant component, and much research has been done around the world to minimize material prices while boosting energy efficiency. The solar panel’s total cost depends on, the brand, size (in W), the durability/longevity, the physical size, and panel’s any certifications. During the last years, photovoltaic panels have been utilized for fewer scale energy production, especially for residential or commercial use in individual or complex buildings with performance ranges between 18 percent to 12 percent. Generally, solar panels have a whole life cycle of twenty-five years. Solar panel selection for a photovoltaic system is a multi criteria decision-making problem involving both quantitative and qualitative characteristics. Multi criteria decision-making is a combined decision-making mechanism as it includes both qualitative and quantitative criterions.
