Locating Ground Faults ("Current Leaks") and Short Circuits
Switch off all equipment individually and disconnect solar panels. Leave the battery switch on. 2. Disconnect the positive battery cable and, with the meter set to the DC volts setting, take a voltage reading between the battery terminal and the cable. If it reads 12 volts — or any voltage, really — you have a leak. 3. Turn the battery ...
I shorted my Panels ... Are they Dead?
Solar panels are CURRENT SOURCES and NOT Voltage Sources like a battery. You can short any panel out for a day, week, month, or year with no problems. In fact that is how you test a solar panel. As CURRENT SOURCE current is limited and in a solar panel is Isc. A shorted panel cannot even heat up its own wires.
Calculation & Design of Solar Photovoltaic Modules & Array
When we connect N-number of solar cells in series then we get two terminals and the voltage across these two terminals is the sum of the voltages of the cells connected in series. For example, if the of a single cell is 0.3 V and 10 such cells are connected in series than the total voltage across the string will be 0.3 V × 10 = 3 Volts.
