The NEM process is bass-ackwards in that you install and pay for the system, THEN apply for the interconnection. Never been a problem before, but with a recent 12 KW application, PG&E said the transformer was too small. We had to get the customer to sign a letter that he would only operate 41 of the 44 modules installed (not that we can disconnect 3 modules in a string system). That would allow the interconnection to go forward until the utility could upgrade the transformer at their expense, in a "few months", and only because it was shared with another customer's service. If it had been a dedicated transformer to the customer, he would have been responsible for the cost of an upgrade. (Eventually the utility said "never mind, operate the whole system".)<o:p></o:p></p><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>We had another 12 kW system coming up, and to be sure we didn't get into a deal-killing problem, I tried to find out in advance if the transformer was adequate. We did step one of the application (the "Agreement and Customer Authorization" form, which specifies CEC-AC rating and annual usage, but not specific equipment). Waited several weeks with no word, then with the job schedule approaching, tried several times to speak to someone. Finally got someone who said " it will probably work, but it needs to be reviewed by engineering", so we need to submit step 2 of the forms, which normally they won't accept unless it's accompanied by the finalled building permit. Catch 22. He said they would "try to work around that".<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>I also asked how a transformer supplying a 200 amp service could not accept 49 amps maximum backfeed, and was told "just because it's feeding a 200 amp panel doesn't mean it's rated for 200 amps. The transformer is only sized to the projected load which could be smaller." I asked how backfeeding is considered load, and was told about possible problems with "flicker factor." So, still waiting to see if I have to give my customer the choice of paying for a $10,000 plus transformer upgrade or downsizing the system. Downsizing to what size? Seems like we would still need guidance on the transformer capacity.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>This has NEVER been an issue before.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p><div><div><div><div><div><p class=MsoNormal><b><span style='font-size:13.5pt;font-family:"Palatino","serif";color:black'>Bruce Erickson</span></b><span style='font-size:13.5pt;font-family:"Palatino","serif";color:black'><o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:13.5pt;font-family:"Palatino","serif";color:black'>Mendocino Solar Service<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:13.5pt;font-family:"Palatino","serif";color:black'>PO Box 1252<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:13.5pt;font-family:"Palatino","serif";color:black'>Mendocino, CA 95460<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:13.5pt;font-family:"Palatino","serif";color:black'>707-937-1701<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:13.5pt;font-family:"Palatino","serif";color:black'>707-937-1741 fax<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:13.5pt;font-family:"Palatino","serif";color:black'><a href="mailto:bruce@mendocinosolar.com">bruce@mendocinosolar.com</a><o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:13.5pt;font-family:"Palatino","serif";color:black'><o:p> </o:p></span></p></div><div><p class=MsoNormal><i><span style='font-size:13.5pt;font-family:"Palatino","serif";color:#A603A8'>Celebrating 20 Years in Solar!</span></i><span class=apple-converted-space><span style='font-size:13.5pt;font-family:"Palatino","serif";color:#A603A8'> </span></span><span style='font-size:13.5pt;font-family:"Palatino","serif";color:#4E3FD3'>1994-2014</span><span style='font-size:13.5pt;font-family:"Palatino","serif";color:black'><o:p></o:p></span></p></div></div><p class=MsoNormal><span style='font-size:13.5pt;font-family:"Palatino","serif";color:black'><o:p> </o:p></span></p></div><p class=MsoNormal><span style='font-size:13.5pt;font-family:"Palatino","serif";color:black'><o:p> </o:p></span></p></div><p class=MsoNormal><span style='font-size:13.5pt;font-family:"Palatino","serif";color:black'><br><br></span><o:p></o:p></p></div><p class=MsoNormal><o:p> </o:p></p><div><div><p class=MsoNormal>On Jan 16, 2015, at 9:38 PM, jay peltz wrote:<o:p></o:p></p></div><p class=MsoNormal><br><br><o:p></o:p></p><div><div><p class=MsoNormal>I am just asking about any advice for the paperwork process above 30kW with pg&e as I've never done one this large for a residence. <o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Customer has a standard 400 amp 240v single phase connection. <o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Thanks <o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Jay<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal style='margin-bottom:12.0pt'>Peltz power <o:p></o:p></p><div><p class=MsoNormal><o:p> </o:p></p></div></div><div><p class=MsoNormal style='margin-bottom:12.0pt'><br>On Jan 16, 2015, at 5:25 PM, Jerry Shafer <<a href="mailto:jerrysgarage01@gmail.com">jerrysgarage01@gmail.com</a>> wrote:<o:p></o:p></p></div><blockquote style='margin-top:5.0pt;margin-bottom:5.0pt'><div><p>Well when you get that large the 3 phase makes a difference<o:p></o:p></p><div><p class=MsoNormal>On Jan 16, 2015 5:23 PM, "William Miller" <<a href="mailto:william@millersolar.com">william@millersolar.com</a>> wrote:<o:p></o:p></p><div><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-family:"Arial","sans-serif";color:#1F497D'>Friends:</span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-family:"Arial","sans-serif";color:#1F497D'> </span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-family:"Arial","sans-serif";color:#1F497D'>I would hesitate before offering three phase to a residential installation.
