Environmental Cost of Solar Panel Manufacturing


Many people wonder if the manufacturing processes for photovoltaic solar modules and also other PV equipment are bad for the surroundings or particularly carbon intensive. There has been a lot of negative press that photovoltaic solar panels could be toxic towards the environment. Carry out the making use of your energy generated from solar power panels outweigh the harmful connection between the manufacturing process?

In accordance with NREL (the nation's Renewable Energy Laboratory), the reality is a PV polycrystalline module will produce enough clean power in approximately 4 years to cancel out the energy necessary to manufacture it. You unfortunately must follow a little energy in order to save far more. Following a module is created and installed, it will be a zero emissions power source for the rest of its life. On the Thirty year life-span, almost 90% in the energy generated from the solar power is going to be pollution free.

The key manufacturing input of PV modules is silicon, the most abundant elements on the planet. It's easily gathered through the the top earth's crust and is available around the globe, eliminating the necessity to transport heavy raw materials. Purifying and crystallizing silicon is among the most energy intensive procedure for manufacturing Solar panels. Energy is additionally expelled when cutting silicon wafers, processing wafers into cells, and assembling cells into panels. The is moving towards recycling PV modules which will save energy in the reuse of silicon cells and metals.

Around the toxicity of solar power systems, experts are already discussing using chemicals within the manufacturing process. Consequently, 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 has, in turn, made PV manufacturers more mindful of risks and they have implemented standards to make the production safer.

Much of the negative news you hear about solar is produced by incumbent energy producers. They really want us to trust which our current energy infrastructure is the only logical answer when it is clearly not. Through the first day a PV installation is turned on, it's going to create clean, green electricity. And, no matter the system generates will reduce its owner's have to 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 every year. This might save about 10,000 pounds of greenhouse gas emissions, which would be similar to planting 20 mature trees annually or driving your car 7,000 miles less 12 months.
