Mismatched solar panel application—charging 6V batteries from 18V solar panels. Normally, solar panels are designed for a specific battery voltage applications. For 12V applications, the solar panel open circuit voltage is generally 18 to 20V. Similarly, for 6V applications, the solar panel voltage open circuit voltage is generally 9 to 10V.
If your charge controller is an MPPT type, you should be able to wire panels in series. If it''s a PWM type, you must use parallel wired panels. Bypass Diodes should exist in nearly all factory made panels. Your charge controller should provide the night time blocking action, and so I don''t think you need any extra diodes at all.

With your approach (directly connecting the solar cell to the battery through a diode) the closer the solar cell voltage is to the battery voltage, the less power is "wasted". But as I mentioned earlier, the solar cell''s voltage and the battery voltage will both vary over time.
A typical battery charging issue is that the solar panel may have too high a voltage to charge a 6-volt battery safely. Thankfully, there are solutions that we go over below.
