I just noticed the original post mentioned "middle TN", so sorry for my first comment. Still, I have to be a little pedantic here, do you mean to imply that developing countries do not have electrical infrastructure? Or that somehow the issues that affect developed countries electrical infrastructure do not affect developing ones? I'm genuinely interested in your line of thinking.

Edit: Let me attempt to be clearer here. Lets assume the reddit post is true. Imagine someone living in Brazil or India, they currently do have electrical power. Imagine the electric grid(or parts of) goes down due to the lack of hardware. Now they don't have electricity nor money to invest in solar power. How is that discussion "immaterial" to them?
