Life / Installing a solar panel in Poland [14]
Ignorant rubbish. Solar cells have a 25 year guaranteed life to 80% output. Thats a hell of lot of energy
10 to 25 years, depending of manufacturer. We had some 40W chinese panels (on a off-grid low power telemetry equipment, of course) that survived only 2-3 years.
And try to figure out how much energy is consumed to produce typical panel starting from sand and bauxite. And compare with typical output of such panel during its complete life cycle. You'll be surprised.
