About 1 to 2 years. Highly variable by technology.
There is a persistent myth that solar panels take more energy to fabricate than they produce in their lifetime. It is shown false with minimal effort (consider if the entire cost of a panel was energy. no labor, not capital equipment overhead, no raw materials… they still have payback periods shorter than their lifetimes).
- vilda 14y agoFor the newest, most efficient panels, it's about 5 years.
