Testing Solar Stringers
How to test your
solar stringers to
make sure they're working properly.
 Procedure For Testing PV Solar
Stringers
Testing pv solar stringers is easy. You can test
your solar stringers one at a time by placing them in direct sunlight and using your multi-meter
just like you did before...
...only this time, instead of testing just one cell, test the whole 9 cell stringer by setting
your multi-meter to "volts" and...
Testing Stringers For
Volts
- touching the multi-meter's (red) positive lead to the tab wire coming from the positive
side of the first cell in your stringer.
- Then touch, the multi-meter's (black) negative lead to the tab wire coming from the
negative side of the last cell in your stringer.
The volt reading on your multi-meter should be close to (or just under) 4.5 volts. If it's not,
there is a problem. Go back and check all the connections of your solar cells or check for cracks
in the cells themselves.
Testing Stringers For
Amps
Next, test your 9 cell solar stringers' amp output by setting your multi-meter
to "amps" and...
- touching the multi-meter's (red) positive lead to the tab wire coming from the positive
side of the first cell in your stringer.
- Then touch, the multi-meter's (black) negative lead to the tab wire coming from the
negative side of the last cell in your stringer.
The amp reading on your multi-meter should be close to (or just under) 3.5 amps.
