This is assuming your shading is from east and west located obstacles...as the morning sun hits the west string, you'll have full output in that string, esp with opti-track. Same in afternoon. Not quite as granular as micros or optimizers but an option. Simple. You'll also have 1500 watts of power without batteries when the grid fails.</div><div style="font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255);" class=""> </div><div style="font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255);" class="">Bill</div><div style="font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255);" class="">Feather River Solar Electric</div><blockquote style="font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); padding-right: 0px; padding-left: 5px; margin-left: 5px; border-left-color: rgb(0, 0, 0); border-left-width: 2px; border-left-style: solid; margin-right: 0px;" class="" type="cite"><div style="font-style: normal; font-variant: normal; font-weight: normal; font-size: 10pt; line-height: normal; font-family: arial;" class="">----- Original Message -----<span class="Apple-converted-space"> </span></div><div style="background-color: rgb(228, 228, 228); font-style: normal; font-variant: normal; font-weight: normal; font-size: 10pt; line-height: normal; font-family: arial;" class=""><b class="">From:</b><span class="Apple-converted-space"> </span><a title="solarworks@gmail.com" href="mailto:solarworks@gmail.com" class="">Kirpal Khalsa</a></div><div style="font-style: normal; font-variant: normal; font-weight: normal; font-size: 10pt; line-height: normal; font-family: arial;" class=""><b class="">To:</b><span class="Apple-converted-space"> </span><a title="re-wrenches@lists.re-wrenches.org" href="mailto:re-wrenches@lists.re-wrenches.org" class="">RE-wrenches</a></div><div style="font-style: normal; font-variant: normal; font-weight: normal; font-size: 10pt; line-height: normal; font-family: arial;" class=""><b class="">Sent:</b><span class="Apple-converted-space"> </span>Monday, October 26, 2015 4:32 AM</div><div style="font-style: normal; font-variant: normal; font-weight: normal; font-size: 10pt; line-height: normal; font-family: arial;" class=""><b class="">Subject:</b><span class="Apple-converted-space"> </span>Re: [RE-wrenches] 72 cell micro inverters</div><div class=""><br class=""></div><div dir="ltr" class="">Jay you also might consider Solar Edge optimizers for partial shade mitigation.
