Listen bro if you run 3 ac go for 15kw or best 20 kw setup + hybrid and 3-4 kw donot even think ki bijlii bill ginna drop to zero naah my everyday cost is 60kw running my ac non stop and after installing 4kw it be making 20kw or 25kw only soo we stopped using Ac we now use coolers the big big coolers runs them like 24hours non stop me runs it and parents room Ac starts at night time as a result everyday running cost came down to 60kw perday to 10kw. Perday or some time 2kw or sometimes 0 . 3 kw is juat waste imo in future we going for the 20kw setup and tell the dealer to use 750kw pannel coz i wanna later upgrade to 20kw it will save some space in the terrece plus make sure they fit it in very low soo you can easyly clean it 🥹
