<p style="margin-left: 0.5in;"> </p>
<p style="margin-right: 0in; margin-bottom: 12pt; margin-left: 0.5in;">This is from an installer in St Croix about and issue
he had. Any thoughts?</p>
<p style="margin-left: 0.5in;"><span style="font-size: 11pt;">
I have a client w/ an older solar array. They are at least as old as 1991, and
I installed 1 new panel and new SW4048 and L-16 bats in Jan 2000. The 24 modules
are Solarex "SX 110" but they have a 2.1 Isc and they measure
17.5" x 42 " each I believe they are @ 35W each. They are
wired 4 modules in series , 6panels@ 48V nom. w/ 2 panels parallel
in J box on roof w/no fuse, or diode. 3 pos </span></p>
<p style="margin-left: 0.5in;"><span style="font-size: 11pt;">power
leads go down to SQ D fused Disconnect (3, 10A FLNR fuses). </span></p>
<p style="margin-left: 0.5in;"><span style="font-size: 11pt;">After
opening PV disconnect at array site, and measuring Voc on each input
terminal (@ 75Voc each) I measured Isc . I got 3.9 on West, 1.9 in middle, and
3.9 on east. After I had finished w/this measure, I Heard a loud pop, and when
we inspected array found 1 panel w/cracked glass and an electrical blow out on
underneath on back sheet of module. </span></p>
<p style="margin-left: 0.5in;"><span style="font-size: 11pt;">This
was the East panel, and measuring Isc on all again, got 3.9 West, 1.9 Mid, and
1.9 Isc East. </span></p>
<p style="margin-left: 0.5in;"><span style="font-size: 11pt;">I
did not wire the array, though I did rewire the j box w.new busses.
Interestingly, each 48 V panel has 2 Pos wires, each measuring 75 Voc .;
i.e. each output circuit (to 10A fuse) has 4 Pos wires coming into it.
Though I did not confirm w/isc test, I imagine that 2 wires were used for Pos
on each 48 V panel. There are also a total of 4 ve wires for ea panel as
well, all ve on 1 buss.</span></p>
<p style="margin-left: 0.5in;"><span style="font-size: 11pt;">All
panels were in direct sun when this blowout event occurred. Also, all
modules had severe darkening of cells.</span></p>
<p style="margin-left: 0.5in;"><span style="font-size: 11pt;">Care
to comment on this, what happened and why?</span></p>
