    No, it's not advised to wire solar panels with different current in series. They should be wired in parallel if they have different current. Can you put solar panels of different voltage in parallel?

    Why do solar panels need to be connected in parallel?

    Connecting solar panels in parallel is just the opposite of series connection and is used to increase the total output current of the array, and hence the total output power while keeping the same voltage. 'The same voltage' is the system voltage which for off-grid solar panels systems is usually as low as either 6V or 12V.

    Are solar panels connected in series?

    When you connect solar panels in series, the total output current of the solar array is the same as the current passing through a single panel, while the total output voltage is a sum of the voltage drops on each solar panel.
