 A Simple Explanation of What Solar Energy is and How it Works

This is the first in a 4-part series by Anna Stone

Light (particularly sunlight) can be used to create heat or generate electrical power.  This is referred to as solar energy.  It is a clean form of energy production, which doesn’t pollute the environment as some other forms of energy production do.

There are two forms of solar energy:

The first is solar thermal conversion, which uses sunlight to create heat and then electrical power.

The second is photovoltaic conversion, which uses sheets of special materials to create electricity from the sun.  “Photo” means “light” and “voltaic” means “producing electricity.”

Many news sites are now retracting the “hair solar panel” story. Unfortunately, it appears to be a hoax. See http://sites.google.com/site/edwardcraighyatt/hairsolarpanelnepal for details.

I suspected it might be that’s why I never promoted the story. Thanks for the update.

Its nice to get the basic facts about solar power. I am looking to find out as much as possible before considering making a move in that direction, as the initial cost is very steep.
