Contacted seller, no longer available...

First time Craig's list user. Seller was very cautious. My friends wanted to know if the panels were being stored in the basement ;). Brought them home yesterday. Seller helped check OC voltages. Also got some rail and hardware from him. All around good experience.

My original post reads in part "anything longer than 65" will overhang my roof edge." They don't have to be 60 cells but most panels with more than 60 are longer than 65". After reading your post I did check Craigslist in my area and found some Trina Solar panels that look like they'd be a...

Another good option, although the width would only allow 2 rows of 6 in portrait mode instead of my original 7 across. But the added power (340 vs. 260W each) entirely compensates. Thanks!!!

Sorry to admit this but I won't have any qualms about reusing the old mounting clamps. I don't live in California;)

These will totally replace the old array so no worries about dissimilar panel voltages in this array. I plan to use the good panels that were left from this lower array, in the upper 2 row array, which are all AC panels with Enphase M215 microinverters.

Those look like a pretty good fit. A little long but maybe the best I can expect to find, unless someone turns up some used ones that are the right size. Thanks!

A tree recently fell on my barn roof and destroyed 15 of the PV modules mounted up there (see photo). 9 of the 15 were Talesun 260W panels about 65" X 40", and those are the ones I'm looking to replace (the lower array of 14 in the photo). However it seems no one is making panels that size...

Finally got a solution from Enphase. After about a dozen back and forth emails with their tech support, I got them to change the grid profile that the M215s were using. It had been IEEE 1547 default, which sets the high AC grid input voltage limit at 132. After requesting that they find a...

I have mechanical watthour meters on the top two rows. I guess I need to take a couple readings to see if my monitoring system is acting up. It's not always bad - screenshot below from 2/26.

Occasionally my barn roof array, comprised of 44 Enphase M215 equipped PV panels, reports extreme variations in the day's energy output between panels (see attached screenshot from today). The roof does have some tree shading issues, but I find it hard to believe that explains some of the...

I use a long handled soft brush. It will only reach the bottom 2 rows unless I get out the ladder, which enables me to reach 3 out of 4 rows. The brush has a squeegee on the reverse side for tougher to remove snow, when I've left it go too long. A lot of work for my 58 panel rooftop areay.

My FLA batteries are in an unheated garage that can get down below 40°F in winter. I added a loop from my hydronic heating system to maintain them at 60°F. Lithium is your best bet but as the Steve_S said you cannot charge them at temperatures below freezing. Also note most building codes...
