I just installed a PV system in columbia in April, 2010 and just had BGE install the Net Meter. I was surprised that it does not show my daily Kwh useage, but just the net Kwh useage. I've got a 4 KW system. Is their any way to cross check that the meter is properly working? You can call or Email me at 410,997-3879 or verchinski@yahoo.com
