I went to part one of a three part evening class tonight, an Access class at Champlain Valley Union High School.  It was presented by Gary Becker of the Solar Bus.  The idea is to get some information about photovoltaics.  Everyone there has some desire to use the sun for electricity generation, including me.  This first class was pretty basic.  We got some general ideas about how things work.  It got me more curious.

Some key points:

Enough sunlight hits the earth every minute to supply all the electricty demand of everyone in the world for a year.

The United States could generate all of its electricity demand from solar power from an area about 45 miles square.

Vermont could generate all of its electricity demand from solar power from an area about 4.2 miles square.

Questions I need answered:

How much electricity would a 1-kilowatt system produce?  What would I need?  And what would it cost?

Those are questions for the next class, when we will get more into the details of how systems work.  We’ll see if I get my 40 bucks worth.
