FAQS about 6v photovoltaic panels connected in series to charge lithium batteries
Can a 6V battery be connected to a 12V solar panel?
When connecting batteries and solar panels, ensure the voltage rating is the same. A 6V battery should not be connected in series/parallel with 12V or other voltage rated batteries or solar panels. Make sure the battery and solar panel voltage rating is the same while connecting them in series, parallel or series-parallel.
Can a solar panel charge a 6 volt battery?
Ideally, the best solar panel to use to charge a six-volt battery is a six-volt solar panel. Because solar energy ebbs and flows throughout the day, the panel will deliver less than six volts of current at its weakest power production. The solar panel will provide a little over 9 volts at its peak.

What if we have one 12V panel and two 6V panels?
How to connect two solar panels with same voltage & power?
If we have two solar panels with same voltage and power, the connection will be very simple.

You connect solar panels in series when you want to get a higher voltage. If you, however, need to get higher current, you should connect your panels 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.
What is the effect of parallel wiring in photovoltaic solar panels?
