An all time myth that keeps hovering over the minds of several solar supporters is whether the making of solar panels is environmentally clean or not. Let’s discuss the making of solar panels from scratch and unleash some unknown facts about solar.
Essentially, a solar panel or a solar board is a series of interconnected silicon cells joined together to create a complete circuit. On a grand scale, the amount of power generated from each of these interconnected cells can be amplified and utilized as a giant hydro production system. At cellular level, solar panels are composed of poly-silicon, mono-silicon or even thin-film cells. While poly silicon cells are made by melting a variety of silicon crystals all together, mono silicon cells are cut from different cylindrical ingots and enhance the overall efficiency of a solar panel as they usually have a higher rating than other technologies.
As quoted by a regional renewable energy advocacy group on their website www.nesea.org, the Northeast Sustainable Energy Association,
“Of all the renewable energy sources available, solar cells have the smallest environmental impacts. Electricity produced from photovoltaic cells does not result in air or water pollution, deplete natural resources, or endanger animal or human health. The only potential negative impacts are associated with some toxic chemicals, like cadmium and arsenic, that are used in the production process. These environmental impacts are minor and can be easily controlled through recycling and proper disposal.”
Even though solar is here and will stay forever, there is no denying in the fact that the making of photo-voltaic panels might involve the use of some explosive and toxic gases, but the magnitude of potential effects varies on the toxic properties of the materials involved and also depends on the frequency, duration and intensity of human exposure to the manufacturing. Solar is among those fewer power generation technologies that have a very little impact on the environment and that too can be controlled by apt utilization of resources. Besides the general making process, solar is the quietest mode of electricity generation, no motors or turbines or heavy machinery involved. Photo voltaic does not remit out any hazardous waste or air pollution. Above all, it does not involve the combustion of any gaseous or liquid fuels for electricity generation.Furthermore, as compared to electricity generated from coal, solar power generation over its lifetime consumes 86 to 89 percent less water, makes use of 80 percent less land, adds 97 to 98 percent less to acid rain and marine eutrophication.
To unravel the mystery, environmental risks from Photo voltaic cells are minimal. Huge scale utilization of PV modules does not present any risk to the health and environment and also, the recycling of modules at the end of life resolves all the environmental issues. In fact, by displacing fossil fuels, they offer great environmental benefits. That is the environmental impact of solar panels!
Grasshopper solar is a long term advocate of good energy and we take every possible measure to reduce the environmental impact from fuels and help more and more people benefit from clean renewable energy and thereby contribute towards a sustainable province, nation and eventually a sustainable world.
We believe solar is free and forever and hence, we offer our Free solar program to make solar free and accessible by one and all.
