For a 24 volt system the panel at max power rating needs to be 32 to 36 volts. Roughly 16 to 18 volts for every 12 volts of battery. However that rule only applies if you are using a standard PWM or shunt regulator. Using that type of regulator you will loose 30% minimum of the power from the panels.
PV panels and batteries are available in the range of 12-23-36V etc. The most common is the 12V system. Obviously, the series connection is less common for solar panel and batteries installation as the system will only increase the level of voltage (from 12VDC to 24VDC) which is only applicable in a 24V inverter system.
This might sound weird, but both are correct and useful: Nominal 12V voltage is designed based on battery classification. With solar panels, we can charge batteries, and batteries usually have 12V, 24V, or 48V input and output voltage. It is the job of the charge controller to produce a 12V DC current that charges the battery.
If you know the number of PV cells in a solar panel, you can, by using 0.58V per PV cell voltage, calculate the total solar panel output voltage for a 36-cell panel, for example. You only need to sum up all the voltages of the individual photovoltaic cells (since they are wired in series, instead of wires in parallel). Here is this calculation:
A 24 volt solar system uses multiple solar panels wired in series to produce a higher DC voltage output around 24V. This 24V DC electricity is stored in batteries and converted by inverters to power 24V appliances and equipment. Installing a solar power system can be a confusing process, especially when dealing with higher 24V systems.
Here’s a step-by-step guide on how to wire solar panels in parallel for a 24V solar system: Gather the necessary materials including MC4 connectors and the appropriate length of solar PV cables to connect the panels to the charge controller. Identify the positive and negative terminals which are typically marked with a red and black wire or symbol.

Charge voltage needed for 24 V system
At higher voltage you use less current for a given power. Ok lets move on to amps. Amps is the function of power and voltage from the panels. So if you have a 200 watt panel at 36 volts the current = 200 watts / 36 volts = 8.3 amps. You mentioned 26 volts at 200 amps. That would be one hell of a big solar panel array of 26 volts x 200 amps 5200 ...
