the light and use it in solar panels at the same time; as it is,
mirrors in this set up are far more effiecient than stand alone
solar panels. Drawback is that you need to do this on a

kind of efficience rates. Also mirrors are far less expensive to
produce and replace than solar panels. September 19, 2007 Sunny
