Photovoltaics – Does this kind of energy generation really have a positive eco-balance?

A misconception stubbornly maintains that PV modules don't produce as much energy that was required to manufacture them.

The state of production technology and processes for monocrystalline modules as practiced during 2009 and 2010 translate into an energy pay-back time of 1.27 years. That means that a monocrystalline solar module from Bosch will produce as much energy as was required to manufacture it in under one and a half years. Nor has the effort ceased to drop that number even further.

Quite the contrary, we're working continiously to improve our products and the processes used to manufacture them.
