45 Drives is a brand ;). Modern servers are reasonably power efficient, and solar helps a lot.

I've got a high density 42RU rack at home, it's a fun hobby.

Could you share some details on your solar setup?

It's not set up yet, but I've been planning it with a sparkie mate.

My rack - despite being high density - is relatively low draw. I'm currently pulling around 500w/h and expect to only burst to about 800w/h.

As such, I'm looking at a 25-30kwh system, depending on what I can efficiantly squeeze in. I'd also like to chain together 2-3 Powerwalls or similar battery systems for a storage capacity of 2 days or so of total draw. I also have an electric car and a family, so 2 days is probably about 40kwh.

The expectation is it'll save around $300-350 a month, so it'll take a few years for ROI, but that's ok - as long as it allows me to feed my hobby!

Ha, that makes more sense!

Actually not bad. I’m Not sure of the actual power draw but it can’t be too bad. Has just a single Corsair 650 watt psu. But the server also has two xeons so I’m probably at least 400 watts.

Oowhee that’s a lot of power. My “server” idles at 50W and it’s already costing me about 10$/month in electricity.

What's your 'server' setup? I like hacky solutions

Nothing fancy, just an i5 4790k
