Manufacturing a solar panel consumes more energy than it will ever deliver.

Truth: Electricity generation plants are measured by the energy yield ratio which is the energy delivered by a system over its lifetime, compared to the energy required to make it. In northern Europe a grid-connected system, with a lifetime of 20 years, produces 4 times the energy required to make (it has an energy yield ratio of 4). In sunnier climes this figure goes up to 7.
