Watts = Volts x Amps, if you use your algebra you will find that it's approx 14 Amps.
To calculate the amperage, use the formula: Amps = Watts / Volts. In this case, it would be 580 watts / 120 volts = 4.83 amps. Therefore, you would need approximately 4.83 amps for a 580 watt device at 120 volts.
A 1000 watt ballast operating at 120V would draw approximately 8.33 amps of current. This can be calculated by dividing the power (in watts) by the voltage (in volts).
A panel does not generate any current, the generating happens at the power plant. A 280 watt panel on a 120 v supply can supply up to 2.3 amps.
The amps drawn by a 65 watt light bulb should be 65/120 or 0.54167. This fraction of an ampere may be restated as 541.67 milli-amps.
Amps measure the current flow so they flow all the time whether it's a minute or an hour, until they are switched off. A solar panel generates watts, that is volts times amps, so if the panel were a 20-volt panel the current would be 2 amps.
Watts = Volts x Amps, if you use your algebra you will find that it's approx 14 Amps.
Answer You need the Voltage and the amps it can supply then use the magic triangle formula that is Watt = Amps X Volts say 400mA 12 volt that will work out to .4X12 = 4.8 watt
There is too much information there. Charging a 100 amp-hour battery fully would take 18 hours at 5.5 amps, or 6 hours at 16.67 amps. At 5.5 amps the power would be 12x5.5 or 66 watts, and this is the rating of the solar panel required. That would be about 0.4 of a square metre.
You would have to add panels in parallel to get more amps and then add a variable resistance in one leg to drop the voltage to your device.
A solar panel develops volts of EMF across its terminals when it's illuminated. If a conducting path is provided between its terminals, then amps of current flow. Just like any other battery or generator.
To calculate the amperage, use the formula: Amps = Watts / Volts. In this case, it would be 580 watts / 120 volts = 4.83 amps. Therefore, you would need approximately 4.83 amps for a 580 watt device at 120 volts.
The short-circuit current (Isc) of a 100W 12V solar panel can be calculated using Ohm's Law: Isc = Pmax / Vmp. Assuming the panel's maximum power point voltage (Vmp) is around 17V, the Isc would be approximately 5.88 Amps.
A 1000 watt ballast operating at 120V would draw approximately 8.33 amps of current. This can be calculated by dividing the power (in watts) by the voltage (in volts).

Use the formula A = W/V, where A is amps, W is watts and V is voltage.
