Myths about sustainability, episode 2: Solar panels production requires lots of CO2 emissions and energy ...

What's the experts view on that? According to the "Photovoltaics report" (July 2021) of Fraunhofer Institute for Solar Energy Systems, ISE, Freiburg, the average "Energy Payback Time" of photovoltaic systems is dependent on the geographical location where they are used: PV systems in Northern Europe need around 1.2 years to balance the input energy, while PV systems in the South equal their energy input after 1 year and less, depending on the technology installed and the grid efficiency. In consequence, in a 20 years lifespan, this kind of system can produce twenty times the energy needed to produce it!
