Arthur T Knackerbracket has found the following story:
Google has for the first time shared some of its data centre designs with the OpenCompute Project (OCP).
Google joined OCP back in March 2016 and, at the time, talked up its 48v racks and promised a new spec that would allow them to work with OCP servers in its own bit bars … and yours, should you choose to use OCP standards.
The Alphabet subsidiary has made good on that promise and shared a rack design in the hope they become part of the Open Rack 2.0 standard. Facebook's chipped in with some help, too.
Google says its efforts comprise a “48V power architecture with a modular, shallow-depth form factor that enables high-density deployment of OCP racks into data centers with limited space.”
The ads-and-search company says it has “extensively deployed these high-efficiency, high-availability systems since 2010.”
“We have seen significant reduction in losses and increased efficiency compared to 12V solutions,” writes technical program manager Debosmita Das and technical lead manager Mike Lau,” adding that “The improved SPUE [Server Power Usage Efficiency] with 48V has saved Google millions of dollars and kilowatt hours.”

I think the biggest ATXV48* you could get will have 0.7kw 48v rail and those panels are in the 2 - 7kw ranges... When it comes to solar, I personally like the idea the air conditioning companies are running with: They offer installs with dedicated solar support. So, you can just setup the AC to turn on whenever it's getting power off the panels and target a specific temperature, and then turn it on manually when it's cold and the skies are cloudy. That covers 2/3 of the year for me. Maybe even much of the winter :)
