This is how the panels that i have built in my other instructables are connected and feed my solar charge controller.

In this first image there are 3 solar panels. 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. If we have two solar panels with the same voltage but different wattage there is no problem. Connecting these panels in parallel will produce 200 watts 18 9v and 10 58 amps under optimum conditions.

If you look at the arrows along the white and red lines they are showing the direction of flow. On the other hand if our two solar panels have both different wattage and different voltage then parallel connection is not possible since the panel with the lowest voltage would behave like a load and would begin to absorb current instead of producing it with the. 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. When solar panels are wired in series the voltage of the panels adds together but the amperage remains the same.

For this example i am showing you connecting panels that are for a 12 volt system. 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. They can be wired in parallel.
