Since watts equals volts times amps 18 volts x 5 55 amps 100 watts.

Solar panels can provide more voltage than listed in peak times and also less power with less sunlight. When just looking at residential solar panels the top wattage panel available is the sunpower a series ac module the top panel in the a series line boasts a wattage of 425 watts.
