I purchased this solar panel before doing my homework. Volts x Amps = watts. 18v x 1.2 amps = 21.6 watts. It's ok if you are charging a cellphone. I wanted to connect to an AGM Battery and power inverter to run 2 - 29 gallon aquariums for a few hours. 21 watts won't cut it. This is a light duty solar panel. I taped the wire down to the back of the panel that comes out of the junction box as it almost pulled out from just handling it. I will glue down the wire. I wish the description was more accurate. It's not charging my 33ah battery fast enough to keep it charged enough that my power inverter alarm won't go on, so I had to incorporate a battery charger which defeats the purpose. After this little experiment, I purchased a real 100 watt solar panel that actually puts out 100 w in full sun for 75.00. Remember to read the specs of any solar panel you buy. Volts x Amps = Watts Oh, if you buy this with a charge controller to charge a car battery that is stored over winter, it probably would be enough to trickle charge it...

  • DigitalConcepts Rule of thumb for anything coming from China regarding power, Drop Off the last zero, in other words this panel is 10 Watts

  • rocketmrv Thanks for Ohm's Law! read below comment. My 1,600 ma is actual 160 ma! Open circuit voltage is different from load voltage. I would also like to know where you bought true 100w for $75. Thanks again!

  • BG196573252 The effectivness of solar panels is 20 percent, so no mppt 100w solar panel should give 20w. Somehow this panel gives at noon in Poland almost 20v with 1.5 amps with is 30 W in regular use. Not bad I say.
