Balancing cells, how much voltage difference?? can they be
All the cells we receive are close to the same voltage. Some will charge in series before parallel top balancing and end up with higher differences in voltage. It''s not good for the cells to connect them if the voltage difference is too high due to inrush current. I don''t know what too high is. I would think under .5 volt difference would be safe.

6 FAQs about [How much current can a solar cell allow ]
What is the value of current in a solar panel?
Much like voltage, there are two important values for current. The first is the short circuit current (Isc). Isc is the maximum amount of current a module can supply and it occurs when the module is shorted and there is no voltage produced by the solar. The second important current is the power point current (Ipp).
What is the voltage of a solar module?
There are two voltages that are important for a solar modules. The open circuit voltage (Voc) is the maximum voltage that the cell will produce and it occurs when there is no current supplied by the module. The power point voltage (Vpp) is the voltage at which the maximum power is available from the cell.
How does a solar module produce current?
The current a solar module will produce is based on the area of the smallest cell. Since the current in an electrical circuit is the same throughout any series string in the circuit, the current out of a series connected solar module is the current generated by the smallest area cell.

What happens when sunlight hits a solar cell?
When sunlight—or even artificial light—hits a solar cell, it energises electrons in the cell’s semiconductor material (usually silicon). This creates a flow of electric current.
