In 2007 I measured the solar to AC and got 63% sorry I have not tracked it since then, other than the demand reduction for the facility, The facility is office 9-5 or 8 to 4 or like that, AC during the summewr is day time only, Every
month of the year this system reduces demand. </span></div><div><span>dt</span></div><div><br></div> <div style="font-family: arial, helvetica, sans-serif; font-size: 12pt;"> <div style="font-family: times new roman, new york, times, serif; font-size: 12pt;"> <font size="2" face="Arial"> <div style="margin: 5px 0px; padding: 0px; border: 1px solid rgb(204, 204, 204); height: 0px; line-height: 0; font-size: 0px;" class="hr" contentEditable="false" readonly="true"></div> <b><span style="font-weight: bold;">From:</span></b> "All Solar, Inc." <allsolar@scswifi.net><br> <b><span style="font-weight: bold;">To:</span></b> 'RE-wrenches' <re-wrenches@lists.re-wrenches.org> <br> <b><span style="font-weight: bold;">Sent:</span></b> Tuesday, December 20, 2011 5:00 PM<br> <b><span style="font-weight: bold;">Subject:</span></b> [RE-wrenches] System Performance | Battery Based Grid Tie<br> </font> <br>
