I'm on someone's Excel spreadsheet at SRP, with the sheet called "Assholes". I use, at my last check, like 2 megawatts per year, or something obscene like that. Powering my server stack is a part of that, but it's probably not that impactful. The two A/C, pool, pool heater/cool (like a third A/C unit) ... And my wife keeps the house around 68F all year ... Soooooo. I really do want solar, but my wife says that project isn't until the late 20s, at best, probably early 2030s. I really want the redundant A/B power supplies with the red cords and black cords. I'm the king of "Isn't that a bit excessive for a homelab?" ... So I think this is right up my alley! --- Thanks, Alexander Sent from my Google Pixel 7 Pro On Wed, Nov 27, 2024, 11:01 Stephen Partington via PLUG-discuss < plug-discuss@lists.phxlinux.org> wrote: > So solar usually pairs best with some level of power storage. and amazon > has some amazing options going right now for far less than what you are > getting quoted. > > Just the fast search comes up with this kit for a ton less than you are > getting quoted. > Bear in mind you will have to add in the cost of connecting it to your > panel, but still an interesting baseline. > > On Wed, Nov 27, 2024 at 12:41 PM George Toft via PLUG-discuss < > plug-discuss@lists.phxlinux.org> wrote: > >> A friend was looking into solar with a Tesla wall (battery).
