Environmental Price of Solar Panel Manufacturing
A lot of people wonder if the manufacturing processes for photovoltaic solar modules along with
other PV equipment are bad for the planet or particularly carbon intensive. There has also been a
lot of negative press that photovoltaic solar power panels might be toxic on the environment.
Perform the together with your energy produced by solar panel systems outweigh the harmful
connection between the manufacturing process?
According to NREL (the nation's Alternative energy Laboratory), the fact remains a PV
polycrystalline module will produce enough clean power within 4 years to counterbalance the
energy needed to manufacture it. You unfortunately need to have a little energy to save additional.
After having a module is manufactured and installed, it's going to be a zero emissions energy
source through out its life. On the 30 year life expectancy, almost 90% in the energy produced by
the solar power will be pollution free.
The key manufacturing input of PV modules is silicon, one of the most abundant elements on the
planet. It's easily gathered in the the top of earth's crust and is available around the globe,
eliminating the necessity to transport heavy recycleables. Purifying and crystallizing silicon is the
most energy intensive means of manufacturing PV panels. Energy is also expelled when cutting
silicon wafers, processing wafers into cells, and assembling cells into panels. A is moving towards
recycling PV modules that can save energy from the reuse of silicon cells and metals.
Around the toxicity of solar panels, experts happen to be discussing the use of chemicals within
the manufacturing process. Because of this, the EPA has cited certain panels as toxic and contains
imposed regulations on employee safety when handling chemicals along with the disposal of toxic
materials. It has, consequently, made PV manufacturers more aware of risks and the've
implemented standards to help make the production safer.
Much of the negative news you learn about solar is generated from incumbent energy producers.
They want us to think our current energy infrastructure is the only logical answer if it's clearly not.
From the first day a PV installation is fired up, it will create clean, green electricity. And, no matter
what system generates will reduce its owner's have to purchase "dirty" electricity. A typical 5 kW
solar electric installation in Massachusetts or Connecticut will provide an equivalent of Ten to
twelve barrels of oil annually. This may save about 10,000 pounds of greenhouse gas emissions,
which may be much like planting 20 mature trees annually or driving your car 7,000 miles less per
