[FAQS about How many watts does a 250kv solar panel require]
We usually measure or convert the watts into amps of solar panels to figure out how much current (amps) is being stored in the battery. Or we measure the amperage of the solar panel. To calculate the current when your solar panel is generating its maximum power, you need to divide the maximum rated power of the panel in watts by the maximum power voltage (Vmp) which is also in volts. You can find the wattage of your panel on the back of it, or in the installation manual. [pdf]
