Connecting solar panels for 24 volt.

This is how the panels that i have built in my other instructables are connected and feed my solar charge controller. Another option would be to replace the 12 volt panel with a 24 volt one but for best results make sure it is a true 24 volt panel with a vmp around 35. So if you connect two solar panels with a rated voltage of 40 volts and a rated amperage of 5 amps in series the voltage of the series would be 80 volts while the amperage would remain at 5 amps. If you answered this question i would like to charge a 24 volt battery bank you would have to connect your panels in series to be able to achieve the necessary charging voltage to charge a 24 volt battery bank.

When solar panels are wired in series the voltage of the panels adds together but the amperage remains the same. If you look at the arrows along the white and red lines they are showing the direction of flow. Since the wiring here is very short and i m certain the goal is to extend run time rather than fully charge the batteries even one of the gt panels with a vmp of 30 would help. They can be wired in parallel.

For this example i am showing you connecting panels that are for a 12 volt system. Volts with two solar panels and two batteries wired in series your panels volts increase to 36 volts and your battery bank s volts go to 24 volts which means you ll be able to power up to 24 volt appliances. In this first image there are 3 solar panels.

Parallel wiring two panel solar system. If we have two solar panels with the same voltage but different wattage there is no problem. Seems to me when you parallel the series wired 12 volt panels with the single 24 volt panel you would end up with something like 12 71 amps at something like 35 4 volts.
