Environmental Cost of Solar Panel Manufacturing


Many people ponder whether the manufacturing approaches for photovoltaic solar modules as well as other PV equipment are bad for environmental surroundings or particularly carbon intensive. We are seeing plenty of negative press that photovoltaic solar panels may be toxic towards the environment. Do the making use of your energy generated from solar power systems outweigh the harmful outcomes of the manufacturing process?

As outlined by NREL (the National Alternative energy Laboratory), the fact remains a PV polycrystalline module will produce enough clean power inside 4 years to cancel out the energy required to manufacture it. You unfortunately must consume a little energy to avoid wasting a lot more. From a module is manufactured and installed, it'll be a zero emissions energy levels for the rest of its life. Over a Thirty year endurance, almost 90% of the energy produced by the solar panel will likely be pollution free.

The most important manufacturing input of PV modules is silicon, one of the most abundant elements on this planet. It can be easily gathered from your the top earth's crust and it is available all over the world, eliminating the call to transport heavy unprocessed trash. Purifying and crystallizing silicon is easily 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 is moving towards recycling PV modules that may save energy within the reuse of silicon cells and metals.

Around the toxicity of solar panel systems, experts are already discussing the use of chemicals within the manufacturing process. As a result, the EPA has cited certain panels as toxic and possesses imposed regulations on employee safety when handling chemicals and the disposal of toxic materials. This has, consequently, made PV manufacturers more aware of risks and they have implemented standards to really make the production safer.

A lot of the negative news you hear solar is produced by incumbent energy producers. They need us to think that our current energy infrastructure is the only logical answer if it's clearly not. From the first day a PV installation is switched on, it's going to create clean, green electricity. And, no matter what system generates will reduce its owner's need to purchase "dirty" electricity. A typical 5 kW solar electric installation in Massachusetts or Connecticut will provide an equivalent of 10 to 12 barrels of oil each and every year. This may 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 a year.
