I few years ago I bought a 40W solar panel from Yahoo Auction Japan for my tiny prefab at work. For years I have been using generators to power up my tools and sometimes I even use a DC/AC converters hooked to my cars just to get some juice to power-up lights. One time I hooked my DC/AC converter to power-up my vacuum cleaner and the vac killed the car's ECU... HAHAHA!
I asked the power guy if he can hook electricity to my prefab and his price is just too much. The only thing that he has that I don't have is the license for hooking-up the power. I have been playing with 240V since I was 7, I climbed electric posts and towers, have played with high voltage and even got electrocuted several times and this guy said that I have to pay around 100,000 Yen. I refused and he offered me that if I do all the work (building the pole, installing the meter, hooking-up the wires to the power pole, and doing all the set-up by myself) and all he has to do is to make it legal, he'll give me a 10% discount... I refused and showed him my huge generator which is enough to run a welding machine.
This is the reason why I stay off-grid because I don't like some wise-ass telling me that I have to pay a lot for his services that I know that I can do myself...
I spend most of the time working at home or moving around and I don't spend much at my lot but when I do, I often get visitors mostly kids. Kids needed the prefab to play and they needed electricity to connect their iPods, PSP or Nintendo DS. Kids also love playing with my Macbook listening to iTunes which is connected to a huge speaker that needed juice from my solar panel.
