Here in Burkina faso, I use between 5 and 12kwh per day with air con some months taking it close to 15kwh. If the price keeps coming down and with some solar installation, one can leave the grid in a couple of years time
I imagine most of the aircon energy usage coincides with the times of peak photovoltaic generation. So if you calculate by total energy consumption, you'll overestimate things by a huge margin.
You can imagine that, but it isn’t true. AC usage is relatively low in the middle of the day because people let their houses warm up while their at work. It jumps at the end of the workday.
