ECN Forum Forums General Topics of the Trade General Discussion Area Solar a viable energy alternative?

It uses a far greater amount of energy to create silicon solar cells than they will return in their limited lifespan as electrical output. The end user may see a benefit of purchasing and installing solar pv in his residence, but as far as " helping to save planet Earth" goes its another looser method. Having said that , I as an electrical contractor see solar pv system installations as a gold mine, and would never let the customer know he is helping to fuel the energy crisis, since he is helping to fund my Mercedes crisis.
