In specific, can a 40 watt solar panel store 100 watts in a battery. Also what is the difference between volts and watts. Another question was that can I was a cigarette lighter power adapter from a car to change the voltage from DC to AC. How does a solar panel system store energy?Seems like your watts, volts and amps confusion has been handled. I'll tackle the headline question.
Some solar panel systems store energy and some don't.
One type of system has no storage capacity at all, hooks up directly to your meter (and the power grid) and delivers power to your house as long as it is generating electricity. Extra capacity is sent to the utility and the home owner's account usually gets credited.
The second type takes any excess capacity and stores it on site. This is done in a battery array. Although one university professor in NJ is doing it with hydrogen.How does a solar panel system store energy?They don't, the only way to store the power they produce is in batteries.
Battery capacity isn't measured in watts they're measured in volts and amps, multiply volts x amps and you get watts. Watts is a term used to measure electrical usage, volts is the amount of electricity passing through a conductor, and amp is the amount of pressure behind the electricity, like the number of gallons of water going through a hose and the amount of pressure behind it. You need what's called an inverter to change DC to AC.How does a solar panel system store energy?%26gt;can a 40 watt solar panel store 100 watts in a battery%26lt;
Yes.

Not that a question like this can really be answered here, a volt is sort of the electrical equivalent to pressure in a pipe whereas watt is a unit of measure for energy.
The last part of your question is clearly screwed up, but I think you are asking can a cigarette lighter from a car be changed from DC to AC.
The device that does that is an inverter, so yes, but you aren't going to be able to get lots of power for a cig lighter either...How does a solar panel system store energy?I think booboo made a booboo-- got your volts %26amp; amps mixed up.
