A solar panel lasts 30 years.
This is why solar energy is clean but not so much.
In 2011 hydrofluoric acid used by the company for solar panel manufacturing contaminated.
To create a solar panel caustic materials will emit greenhouse gases.
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.
Yet manufacturing all those solar panels a tuesday report shows can have environmental.
According to the study a solar panel in sweden generates 50g of co2 per kwh so that is a total of 274 kg of co2 or 600 lbs of co2.
A 6 6kw solar system will produce around 10 600 kwh a year which will save around 10 6 tonnes of co2 emissions per year.
But on average 1m2 of current design solar panels will produce about 0 5 kwh per day better in sunny places and worse in others.
Of electricity generated from conventional sources creates approximately 1kg of co2.
Also recycling faulty panels or those at the end of their life leads to environmental problems.
Once the team accounted for all this they found that solar panels made today are responsible on average for around 20 grams of carbon dioxide per kilowatt hour of energy they produce over their.
As a result when the panel produces clean energy in china the production of greenhouse gases increases.
This will displace electricity purchased from your utility.
