Need guidance on solar system installation in Karachi

Hi, I have been planning on installing a solar system for my house, but solar tech is an area where I don't have much knowledge on what is a good product/brand or not. I have just done the basic amount of research and know that I want a hybrid system with batteries, so I wanted to ask what I should be getting and around how much it will cost me in total. My daily consumption is high (I feel) due to it being summers, and we have erratic load shedding in the area; like, there can be weeks without any power outage, but then there can be 3 or 4 back-to-back, so it depends. My house also has the following appliances: 7 normal fans, one fridge, one deep freezer (run 24/7), two 1-ton non-inverter ACs, two 1.5-ton ACs (one is an inverter), one water motor, one microwave, 3 WiFi routers, and one iron (used almost daily), one desktop PC, two smart TVs, and then other small stuff like charging of phones/laptops, etc. I would love to get info on what kind of KW system I should get for all this, plus how much battery backup I should have if I want to run most of the stuff at night as well. Overall, I want information on how I should proceed with the current appliances we have.
