Yes it s true that making solar panels creates carbon dioxide but over the life of a solar installation it produces on average of 30x less co2 than coal power.
Co2 emissions solar panel.
Energy payback for solar panels is 1 3 years.
Even at this top end however solar s footprint is very low compared to other sources.
To create a solar panel caustic materials will emit greenhouse gases.
Solar panels payback the energy in 1.
For instance concentrated solar power csp has a footprint of 20 grams of carbon dioxide co2 per kilowatt hour kwh of electricity produced in addition to consuming vast amounts.
By scott cramer although the use of solar panels is green many solar panel manufacturing processes are not.
The findings are presented in units of global warming potential per unit of electrical energy generated by that source.
Here s another way to look at it even using lca life cycle assessment wikipedia.
Making and using solar panels emits zero co2 in a 100 renewable energy system.
