The voltage of a solar panel is the result of individual solar cell voltage, the number of those cells, and how the cells are connected within the panel. Every cell and panel has two voltage ratings. The Voc is the amount of voltage the device can produce with no load at 25º C.
Think of voltage as the pressure in a water pipe; the higher the pressure, the more water flows through the pipe. In the context of solar panels, voltage is crucial because it determines how much potential energy the panel can generate. Different solar panels have varying voltage ratings, typically ranging from 12V to 48V.
The current (in amperes, A) produced by the solar panel can be determined using Ohm’s law, where the current is the power divided by the voltage: Current (A) = Power (W)/ Voltage (V) Given that our adjusted power output is 258W and the operating voltage of the panels is 36V, we can substitute these values into the formula to find the current:
A 12-volt solar panel giving a peak output of approximately 18 volts will be enough to charge a 12-volt battery (with the solar charge regulator regulating the voltage). A power inverter converts the DC (direct current) power to regular household volt AC (alternating current), from which you can run most of your household appliances.
This means that when this solar panel is producing 100 Watts of power under Standard Test Conditions, It will be generating 5.62 Amps of current. On the other hand, the Short Circuit Current rating (Isc) on a solar panel, as the name suggests, indicates the amount of current produced by the solar panel when it’s short-circuited.
Measuring volts is a fairly simple procedure. A simple Voltmeter or Multi-meter from your local hardware store is all you need. Set the meter to DC Volt in the appropriate range. Touch the probes of the meter to bare wire at the end of the cables and you can measure the voltage of the panel. Be careful not to let wires touch each other.

Solar panels have great lifespans, and a 12-volt system can last up to 30 years if it''s maintained properly. As opposed to some of the higher voltage solar panels available, 12-volt solar panels are cheaper than most others. Lastly, if somehow the solar panel stops working or breaks, parts for 12-volt systems are always readily available.
