NMOT test conditions account for the most conditions (solar irradiance, wind speed, air mass, back-of-module temperature, efficiency drop at higher solar panel temperatures, measuring the solar panel output when under load) and will thus produce the most accurate real-world solar panel outputs (in terms of wattage, voltage, and amps).
When we connect N-number of solar cells in series then we get two terminals and the voltage across these two terminals is the sum of the voltages of the cells connected in series. For example, if the of a single cell is 0.3 V and 10 such cells are connected in series than the total voltage across the string will be 0.3 V × 10 = 3 Volts.
