How much electricity bill do you pay monthly?

I went to a rich friends house this weekend and while casually discussing the new solar panels they installed, I got to know their average monthly electricity bill was around 30k-40k and since they have installed solar it has come down to 20k approx...

I was shocked because the maximum electricity bill, I've ever paid is around 7k which was pretty high for me and usually it is around 2k.

Is this kind of electricity bill usual?
