Environmental Cost of Solar Panel Manufacturing

A lot of people wonder if the manufacturing methods for photovoltaic solar modules and other PV equipment are unhealthy for the planet or particularly carbon intensive. There has also been lots of negative press that photovoltaic solar panels can be toxic to the environment. Perform the cooking with your energy produced by solar panel systems outweigh the damaging results of the manufacturing process?

As outlined by NREL (the nation's Renewable power Laboratory), the reality is a PV polycrystalline module will produce enough clean power within 4 years to cancel out the energy forced to manufacture it. You unfortunately must have a little energy in order to save additional. After a module is produced and installed, it will be a zero emissions power source for the rest of its life. Over the 30 yr life span, almost 90% with the energy produced by the screen is going to be pollution free.

The main manufacturing input of PV modules is silicon, just about the most abundant elements on this planet. It can be easily gathered in the the top earth's crust and is available around the globe, eliminating the requirement to transport heavy recycleables. Purifying and crystallizing silicon is regarded as the energy intensive means of manufacturing PV panels. Energy can also be expelled when cutting silicon wafers, processing wafers into cells, and assembling cells into panels. The market is moving towards recycling PV modules that can save energy in the reuse of silicon cells and metals.

With regards to the toxicity of solar power panels, experts happen to be discussing the application of chemicals inside the manufacturing process. As a result, the EPA has cited certain panels as toxic and contains imposed regulations on employee safety when handling chemicals and the disposal of toxic materials. It's, subsequently, made PV manufacturers more aware of risks and they've implemented standards to really make the production safer.

A lot of the negative news you read about solar is produced by incumbent energy producers. They want us to trust that the current energy infrastructure could be the only logical answer if it's clearly not. In the first day a PV installation is turned on, it is going to create clean, green electricity. And, regardless of the system generates will reduce its owner's need to purchase "dirty" electricity. A normal 5 kW solar electric installation in Massachusetts or Connecticut will provide an same in principle as 10 to 12 barrels of oil every year. This might save about 10,000 pounds of greenhouse gas emissions, which will be similar to planting 20 mature trees annually or driving your vehicle 7,000 miles less annually.
