Salamander works with a mix and everyone should work with a mix of wind and solar power.
If you have a wind mill then you really should add solar panels. There are times when you have enough wind to run your wind mill and maybe less sun and there are times when you do not have too much wind but enough sun.
I never mentioned a price of 50000 US$. I always said that the list price without shipping and customs is 50000 US$. I'm going to sell this windmill to somebody who offers a reasonable price.
