Great read and loved the video showing your setup! I totally agree, there just aren't enough resources available out there for solar mining yet.

I've been mining Ethereum for a while now and had grown very interested in the plausibility of solar power for my rigs. I can see from your article that GPU mining would likely be too much power for a cost-effective solar setup. I'm assuming Antminers have considerably less draw than GPU-based mining?

This certainly looks to be a viable option!
