Generating clean power, reaping a healthy financial return and all without lifting a finger, is still a luxury, but is one that is becoming much more common as the solar PV industry goes through a rapid growth phase. But is solar really as clean a technology as we might like to believe?
In terms of energy use, the answer is emphatically "yes". There is a myth that more energy is used in manufacturing solar panels than is ever produced by them.

And these modules have a lifespan of more than twenty years.
