Electrical energy is important because it is versatile, manipulated easily and can be used in everybody’s daily life. Without electricity, humans would have to use other kinds of energy that are less efficient & effective. Electricity is recognized as a very efficient way of one’s consumption in part because it is weightless as well as easy to distribute. Electricity is utilized without creating loss and without creating pollution. Other varieties of energy experience loss, pollution or both, such as non-renewable fuels. The sun provides a tremendous resource for producing clean and sustainable electricity. Photo voltaic panels glimmering in the sun invariably is an icon of all that is green and renewable. While producing electricity through photovoltaic is indeed better for the environment than burning fossil fuels.
However, the production technology for solar modules requires relatively high energy. Solar energy systems offer significant environmental benefits in comparison to the conventional energy options. So People are quickly moving toward solar PHOTO VOLTAIC panels because they are the best way to convert sun light in to electricity, and they also reduces air pollution which is produced through coal power plants. As coal power plants filter their emissions, trace amounts of toxic air particulates penetrate air filtering systems and enter the atmosphere. Mercury is among the pollutants that enter the air from coal electric power plant emissions, and it can contaminate local environmental systems and harm plant life, wildlife and human inhabitants.
So at one aspect we can say that solar PV panels is beneficial and helpful for us because they reduce different pollutants but in another side the predominant negative environmental impacts of photovoltaic come from while it’s production. Production of these panels consumes substantial amounts of energy and produces waste water and hazardous by-products which are released to the air
during the manufacturing process. Which usually effects on our environment. These types of possible problems may be considered a strong barrier for further advancement of these systems in some consumers.
For times however, the extensive scale deployment of such systems has to face potential negative environmental effects, that ought to be removed for batter expansion of PV panels.
Releasing Greenhouse Gases
The manufacturing of solar panels can have a negative impact on the environment. Solar panel manufacturers release greenhouse gases and other pollutants into the atmosphere during the manufacturing and doping process of photo voltaic panels. Transportation of photo voltaic panels will also have a negative impact on the environment if non-renewable fuels are being used during transportation.
Water is yet another issue
Photo voltaic manufacturers use a lot of it for various purposes, including cooling, chemical processing, and air-pollution control. The biggest water waster, though, is cleaning during manufacture and use. Utility-scale projects in the 230 to 550-MW range can require up to 1.5 billion liters of water for dust control during construction and another 26 million liters annually for panel washing during operation. On the other hand, the amount of water used to produce, set up, and operate photovoltaic panels is significantly lower than that required to cool thermoelectric fossil and fissile power plants.
The Photovoltaic Cell production technique consists of some of unsafe substances, nearly all of which might be getting used to clean and purify the semiconductor surface. These kinds of chemical substances, much like the ones used in the general semiconductor industry, consist of hydrochloric acid, sulfuric acid, nitric acid, hydrogen fluoride, trichloroethane, and acetone. The amount and type of chemicals used will depend on the kind of cell, the amount of cleaning that is needed, and the dimensions of silicon wafer. Workers also face risks associated with inhaling silicon dust.
Thin-film PV cells comprise a number of greater poisonous substances than those utilized in conventional silicon photovoltaic cells, which include gallium arsenide, copper-indium-gallium-diselenide, and cadmium-telluride. If no longer dealt with and disposed of| nicely, these substances should pose severe environmental or public health or fitness threats.
Land Use Consequences
Photo voltaic panels can be installed on the rooftops of buildings, which eliminates the necessity to clear land for this form of energy production. However, these rooftop installations are only capable to power one building. Utility-scale photo voltaic power installations require a lot of space because solar powered energy collection is relatively inefficient; usually it takes up to 10 acres of photo voltaic panels to produce 1 MW of electricity, based on the Union of Concerned Scientists. Clearing land for a solar energy plant can spoil flora and fauna habitat and degrade soil quality through disposing of vegetation and their root structures.
Recycling Photovoltaic Panels
The recycling of solar panels faces a massive problem, particularly, there aren’t sufficient places to recycle old solar panels, and there aren’t sufficient non-operational solar panels to make recycling them economically appealing. Recycling of solar panels is specifically crucial due to the fact the substances used to make the panels are uncommon or precious substances, they all being composed of silver, tellurium, or indium. due to the restricted capability of recycling the panels, the one’s recoverable metals can be going to waste substances which might also result in resource scarcity or shortage troubles in the future.
