The only time it would be recommended to wire in series would be if your solar panels have different voltages such as a 12V and a 24V solar panel as it will give you the higher voltage option.
Solar Cell Panel- 4V 100mA A solar cell is a key device that converts light energy into electrical energy in photovoltaic energy conversion. Solar cells are generally classified into four generations depending on the time and categories of materials that are used for their fabrication.
Thanks Mike, yes it could be batteries drifting down to resting voltage, I was just worried since I''ve seen other voltage charts showing 12.4v as 50% SOC but if the chart you''ve posted here is accurate then I think I shouldnt worry that much since the lowest I''ve seen the battery bank drop is 12.2v that is in the morning before the sun hits the panels.

Why would my system only show charger ouput of 12.4 volts and drop as it is in use, the voltage drops and then it runs the battery down. I have two 100w panels going to a 20amp charger, input voltage is 13.7 with 10.7 amps current draw. It acts like the panels can''t produce enough power to run my systems when the sun is up. Any thoughts?
This can be a good option if your roof isn''t a suitable place to put a solar panel system. However, they may need foundations and can also be pricey. Find out more about
so if your battery is at 12.4v, technically the charge controller only needs to be 12.5 to begin charging, it only needs to be slightly higher in order to push power into the battery. from my observation, the panel needs to reach pretty much full voltage, then i can start to deliver amps. Solar panels usually have multiple voltage ratings
