Dave Plowman (News) explained :
So you are saying all solar power devices take more energy to make than
they will produce in their lifetime? Which of course is rubbish. So the
alternative would be that all the energy they produce is wasted in some
way.

Without getting involved with any balance sheets, my guess would be
that yes they do generate more greenhouse gases in their manufacture,
installation and maintenance than they could possibly save.
