Environmental Cost of Solar Panel Manufacturing

A lot of people wonder if the manufacturing processes for photovoltaic solar modules along with other PV equipment are harmful to the surroundings or particularly carbon intensive. We are seeing plenty of negative press that photovoltaic solar panel systems might be toxic to the environment. Perform benefits of the energy produced by solar panel systems outweigh the dangerous results of the manufacturing process?

As outlined by NREL (the National Renewable power Laboratory), the simple truth is a PV polycrystalline module will produce enough clean power in approximately 4 years to cancel out the energy required to manufacture it. You unfortunately have to enjoy a little energy to save lots of additional. After having a module is created and installed, it's going to be a zero emissions source of energy for the rest of its life. More than a 30 yr life span, almost 90% from the energy produced by the solar panel will probably be pollution free.

The most important manufacturing input of PV modules is silicon, probably the most abundant elements on earth. It really is easily gathered from your the surface of the earth's crust which is available worldwide, eliminating the need to transport heavy unprocessed trash. Purifying and crystallizing silicon is among the most energy intensive procedure for manufacturing Solar panels. Energy can also be expelled when cutting silicon wafers, processing wafers into cells, and assembling cells into panels. The industry is moving towards recycling PV modules which will save energy in the reuse of silicon cells and metals.

With regards to the toxicity of solar power panels, experts have already been discussing the usage of chemicals from the manufacturing process. As a result, the EPA has cited certain panels as toxic and it has imposed regulations on employee safety when handling chemicals along with the disposal of toxic materials. It is, consequently, made PV manufacturers more mindful of risks and they've implemented standards to help make the production safer.

A lot of the negative news you hear about solar is produced by incumbent energy producers. They really want us to trust our current energy infrastructure could be the only logical answer when it is clearly not. From the first day a PV installation is turned on, it is going to create clean, green electricity. And, whatever the system generates will reduce its owner's must purchase "dirty" electricity. A typical 5 kW solar electric installation in Massachusetts or Connecticut will produce an same in principle as Ten to twelve barrels of oil each and every year. This might save about 10,000 pounds of greenhouse gas emissions, which will be much like planting 20 mature trees annually or driving your vehicle 7,000 miles less a year.
