Environmental Cost of Solar Panel Manufacturing


Many individuals ponder whether the manufacturing systems for photovoltaic solar modules along with other PV equipment are harmful to the surroundings or particularly carbon intensive. We are seeing a great deal of negative press that photovoltaic solar power systems might be toxic for the environment. Perform the benefits of the energy produced by solar panels outweigh the damaging outcomes of the manufacturing process?

In accordance with NREL (the country's Alternative energy Laboratory), the fact remains a PV polycrystalline module will produce enough clean power in approximately 4 years to offset the energy required to manufacture it. You unfortunately need to consume a little energy to avoid wasting far more. After having a module is produced and installed, it'll be a zero emissions energy levels throughout its life. Over a 30 year life span, almost 90% with the energy generated from the cell will probably be pollution free.

The major manufacturing input of PV modules is silicon, just about the most abundant elements in the world. It's easily gathered from your the top of earth's crust and is also available all over the world, eliminating the necessity to transport heavy recycleables. Purifying and crystallizing silicon is regarded as the energy intensive technique of manufacturing PV 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 can save energy from the reuse of silicon cells and metals.

In regards to the toxicity of solar power systems, experts happen to be discussing the application of chemicals within the manufacturing process. Therefore, the EPA has cited certain panels as toxic and possesses imposed regulations on employee safety when handling chemicals and the disposal of toxic materials. It has, consequently, made PV manufacturers more conscious 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 really want us to think that the current energy infrastructure will be the only logical answer when it is clearly not. In the first day a PV installation is fired up, it will create clean, green electricity. And, no matter the system generates will reduce its owner's should purchase "dirty" electricity. The average 5 kW solar electric installation in Massachusetts or Connecticut will provide an equal of Ten to twelve barrels of oil each year. This would save about 10,000 pounds of greenhouse gas emissions, which would be similar to planting 20 mature trees annually or driving your car or truck 7,000 miles less per year.
