We have added an additional 100 KW of PV at that site, and at the new temple, Cintimani. Those Kyocera modules that were installed there failed. I found that about 1/3 of the modules were producing 0-10 Voc, vs the 21 Voc specified. As a result, of the low string voltages,the SMA inverters were underperforming significantly or not turning on at all. Kyocera replaced the entire array with new modules, and paid us a fair wage for the trouble. I have spent a couple months of my life working there, which was very peaceful and interesting, to say the least.<br><div> Each one of those prayer wheels has over a mile of prayers
inscribed on a long strip wrapped inside of them. I think I calculated that their were nearly 800 of those wheels, spinning continuously. They say that those wheels send out ~500 million prayers a day!<br></div>Nick Soleil<br>Project Manager<br>Advanced Alternative Energy Solutions, LLC<br>PO Box 657<br>Petaluma, CA 94953<br>Cell: 707-321-2937<br>Office: 707-789-9537<br>Fax: 707-769-9037<div><br></div><div style="font-family: arial,helvetica,sans-serif; font-size: 12pt;"><br><div style="font-family: times new roman,new york,times,serif; font-size: 12pt;"><font face="Tahoma" size="2"><hr size="1"><b><span style="font-weight: bold;">From:</span></b> Jeff Oldham <starpower4u@juno.com><br><b><span style="font-weight: bold;">To:</span></b> re-wrenches@lists.re-wrenches.org<br><b><span style="font-weight: bold;">Sent:</span></b> Fri, February 11, 2011 8:51:34 AM<br><b><span style="font-weight: bold;">Subject:</span></b> Re:

<meta http-equiv="x-dns-prefetch-control" content="off"><div>Jay is correct about the economics, but sometimes we must live with them as the only way to increase daily water production. However when the tracker fails they will not be making the daily need anymore and it is far more likely to be left dead than even batteries.</div><div> </div><div>In developing communities I have often used a "village tracker", a manually tracked array that anyone walking by can move to the sun. Along the line of Buddhist Prayer Wheels that are kept spinning by passerby's. As an aside I once did a 40kW grid-tied PV system for a temple to offset the load of the countless motors spinning their Prayer Wheels (not enough people passing to keep them all spinning).</div><div> </div><div>From the Solar, Wind and Hydro powered office of Jeff Oldham/Regenerative SOLutions</div><br><br><font color="#000000"
