Need finding for DP-4

Andrew and I went to San Francisco and talked to a friend that owns and operates a snowboard manufacturing shop called Glisade snowboards.  

He let us have a look at his solar array and talked to use about his set up.  

He told use that it will take seven years for the investment to pay off, but that his power bill was 2/3 rds lower.

His favorite thing to see is the meter "running backwards"!

The company has many large machines that eat a lot of power but the Bender Brothers have made the commitment to get as much of there power from clean source as possible.
