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><o:p></o:p></p>

opening PV disconnect at array site, and measuring Voc on each input

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><o:p></o:p></p>

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><o:p></o:p></p>
