Hello everyone,

I'd go for using that extra module with the damaged frame. What is the
frame damage going to do to the system?
Is it bad enough that the module could quit working later (bad edge seal)?
The voltage mismatch isn't the end of the world either, but your over
all year round performance will be bett

The 43volt 5.5 amp panel will operate at 3.6 amps, so it's voltage will move up
toward open circuit voltage, raising the mppt voltage of that string. I would
bet that the voltage of that entire string will rise to match the higher
voltage string by moving toward open circuit voltage. It s
Hello everyone,
I am at present adding to a -20- panel array of old Sanyo HIT "lipped" 200
watt panels. They are configured in -4- series strings of -5- panels, with a
string MPP voltage of 279 vdc (55.8 v, 3.6 a each). The customer wants to
add another nominal 2 kw using the (now) Panasonic 23
I use gutters all the time. I zip tie the wires of the separate voltages
together and label them with a label maker.Psses inspection every time.
