Yes you're right! Right now I have three S7s and they are running on solar and hydropower which's power is stored on batteries for night time. I live far from urban area and here is the right place to expand my site. I have solar panels which are on a 150sqF area and hyrdropower from the heavy river.
where are you in europe or usa?

So the Solar + Hydro with Battery Storage is up and running? How much Solar & Hydro Power can you generate?
Rich
Solar + Hydro if your doing it yourself will never end up being as cheap as cheap electricity. I think you might be better off at a hosting center.
Some are no vat. And it saves you from having to spend on long term investments like solar.
