thanks for the reply,

well first a hydro plant is not possible due to no river or floating water nearby. a generator consumes aprox 8-10k USD of Diesel at this Power. solar system i heard of something from 1000$ per kw for hardware and installation i dont have at the moment the place to host something like this. I got 12 hours free electricity at my place but need to cover the other 12 hours by myself. i think there is no other way then a big Diesel generator providing the electricity needed.
