Carbon Footprint Of Solar Panel Manufacturing

Panels produced in china which relies heavily on coal for power have a larger carbon footprint than those produced in europe.

Carbon footprint of solar panel manufacturing.

By scott cramer although the use of solar panels is green many solar panel manufacturing processes are not. For instance concentrated solar power csp has a footprint of 20 grams of carbon dioxide co2 per. The production of photovoltaic panels still has an important carbon footprint and creates a series of waste liquid and gaseous by products that are harmful to the environment. The footprint of solar comes in at 6gco2e kwh and wind is also 4gco2e kwh.

Solar panel manufacturers need electricity and thermal energy and carbon emissions from their generation can vary widely with location. Heath and colleagues at the doe s brookhaven national laboratory found that the footprint of solar power varied from 14 to 45 g co2 kwh depending on the type of material used. Using solar panels to harness energy from the sun is a great way to make the switch to green electricity. The carbon footprint of a solar photovoltaic pv panel the average level of greenhouse gas emissions it is responsible for over its lifetime is about 72 grams of carbon dioxide equivalent per kilowatt hour of electricity generated gco2e kwh.

To create a solar panel caustic materials will emit greenhouse gases. Solar energy is a naturally occurring renewable energy source which is why more and more people are choosing to invest in solar panels to power their homes. Firstly the extraction of quartz the crystalline form of silicon and of the other materials necessary for the construction of the panels. The fact is that even solar power plants have an environmental footprint on a lifecycle basis.

The figures for ccs are elevated for two reasons. A 2016 study reports that the overall emissions produced in this process decreased by 17 to 24 percent every time install capacity has doubled in the last 40 years. In contrast coal ccs 109g gas ccs 78g hydro 97g and bioenergy 98g have relatively high emissions compared to a global average target for a 2c world of 15gco2e kwh in 2050. As solar panel manufacturing becomes more efficient its carbon footprint shrinks significantly.
