Environmental Cost of Solar Panel Manufacturing


Lots of people wonder if the manufacturing approaches for photovoltaic solar modules as well as other PV equipment are damaging to environmental surroundings or particularly carbon intensive. There has been plenty of negative press that photovoltaic solar power systems might be toxic for the environment. Do the cooking with your energy produced by solar power panels outweigh the harmful effects of the manufacturing process?

According to NREL (the country's Renewable power Laboratory), the simple truth is a PV polycrystalline module will produce enough clean power in about 4 years to offset the energy needed to manufacture it. You unfortunately have to enjoy a little energy in order to save much more. After a module is created and installed, it will be a zero emissions energy levels through out its life. Over the 30 year endurance, almost 90% with the energy produced by the solar power will probably be pollution free.

The main manufacturing input of PV modules is silicon, just about the most abundant elements on this planet. It really is easily gathered from your the top earth's crust and is also available across the world, eliminating the necessity to transport heavy recycleables. Purifying and crystallizing silicon is among the most energy intensive process of manufacturing Solar panels. Energy is also expelled when cutting silicon wafers, processing wafers into cells, and assembling cells into panels. The is moving towards recycling PV modules that may save energy within the reuse of silicon cells and metals.

Regarding the toxicity of solar power panels, experts have already been discussing the use of chemicals inside the manufacturing process. Consequently, the EPA has cited certain panels as toxic and has imposed regulations on employee safety when handling chemicals along with the disposal of toxic materials. It's, consequently, made PV manufacturers more aware of risks and they've implemented standards to help make the production safer.

Much of the negative news you read about solar is generated from incumbent energy producers. They need us to believe our current energy infrastructure could be the only logical answer when it's clearly not. From your first day a PV installation is fired up, it's going to create clean, green electricity. And, whatever the system generates will reduce its owner's must purchase "dirty" electricity. An average 5 kW solar electric installation in Massachusetts or Connecticut will provide an same in principle as Ten to twelve barrels of oil each and every year. This may save about 10,000 pounds of greenhouse gas emissions, which would be comparable to planting 20 mature trees annually or driving your vehicle 7,000 miles less a year.
