Of course, you can have lots of battery power too (as long as there is enough capacity on the panals and batteries). Batteries are about 40% efficient so you are losing lots (60%) of energy there (heating the battery and giving off hydrogen and oxygen gas) and those inverters are inefficient too so... I am going to try out using pressurized air in a large underground air tank to store energy (very efficient, no acids, no chemicals, no explosive gasses, long lifespan of equipment) and you can get most tools in pneumatic form and I even have refrigeration ideas. I figure an AC alternator turned by a pneumatic motor with a speed control can make your AC at household voltage very efficiently (there is also a design that uses air to vibrate a coil or permanent magnet and make AC without turning parts to wear out... I will try that too)

wow, that sounds great! :-)
