When should I expect this cheap electricity to be reflected in their utility bills?
It would be reasonable to expect at least half of those nations to realize lower cost per kWh if solar LCOE is so cheap. Else, it indicates extreme corruption and the expectation that those corrupt agents spend time behind bars.
All that said, I could see solar being cost effective in a place like Hawaii where the weather and temperature is fairly consistent day and night, and through the seasons. They've got limited area to install said solar, so it probably makes the most sense to utilize rooftops and incorporate battery storage.
Anyone saying that a particular energy solution is the best universal energy solution hasn't got a clue, because every area has unique resources and electricity demand profiles.

As I understand, fluorescent is the most popular way to create white light, but it isn't as efficient as RGB lighting. Perhaps the reason it's more popular is a superior Color Rendering Index (CRI)?
