Connecting solar panels in series
With a series connection, the voltages of the panels are added together. The current does not change.
Since each panel has a voltage of +-35V and can deliver a current of 7A, we obtain a voltage of 105V at the charge regulator and a current of 7A.
It's the charge regulator's job to convert this voltage into a voltage suitable for the batteries. (lower the voltage and increase the current).
For example:
If 105V and 7A reach the charge regulator (3 panels of 245W in series, 735W), the output of the regulator on a 24V system will be: +- 25V and 26A which will go into the batteries. (650W)
Be careful never to exceed the maximum voltage accepted by the charge regulator.
