it will definitely cost over 8000$
I disagree. It depends how much kWh do you spend per day. But it's absolutely less, with basic spending. I'm not sure how much shipping to Lebanon will cost, but with less than 3000$ you can build a system that provides at least 1 kWh (understandably not much but enough for basic needs). And it can scale cheaply too.
Keep in mind that prices of solar panels are going down, thanks to chinese online retailers. This affects efficiency too. There are lots of factors that goes into the build price of your solar system.
Even on amazon, you can get 1.5 USD/Watt for solar panel with a 20A controller, and that's on the pricey side too.
Also batteries play a big role in the price estimation, and they can be provided locally or recycled. So there is lots of room for saving.
Guys, please take some time to actually read the guide, as the components prices are listed there. Prices varies depending on your needs and the efficiency of your system. Also shipping plays a role.
Roughly speaking, solar panels alone, with 200W would cost around 339$ (not including shipping to Lebanon). That's less than 1.5$/Watt.
Keep in mind that, this is on the "pricey side" too. With enough research you can reduce that, especially if you consider chinese online retailers (again links included in the actual guide above).
If you also source batteries locally, and recycle some other material you can save up more.
I would estimate the total would be less than 3000$ for a 1kWh system (this is rough upper bound estimation).
The Ecoflow 220w panel will NOT work with your Bluetti because it has an open-circuit voltage of 21.8V and the AC200P accepts a minimum of 35V to start working. The AC200P works with voltage up to a maximum of 150V for 700W of solar charging.
You will need to either purchase a second one of those panels and wire them in series or purchase different panels. I personally can vouch for the portable Renogy suitcase panels, I have both the 100W and 200W versions. IMO they're better than the Ecoflow 220w because they're sturdier and they use glass for better longevity and heat dissipation than plastic film protection on most portable panels. If you have a ~$600 budget for your panels I'd go with 2x 200W panels wired in series (which brings the open-circuit voltage to 2x21.8V = 43.6V) - you would not have any use for the bundled 20A solar controller that comes with the panels which is just for charging batteries directly and is not for power stations because the stations have their own MPPT charge controller.

They are designed to be left outside and are rated IP66 against dust and water - I've had mine out consistently for many months with no problems. Just learn from my mistakes and tie them down to the ground with sandbags or strings and hooks so they don't sail away in strong winds!
1 kWh is good enough, given that it's self sufficient solution. You can also scale it up with time.
For reference, you can power a modem, a ceiling fan, a laptop and a light with less than 1 kWh.
The pricing of solar pannels are in 1 watts = 2.4-3$
I am not sure how accurate is that estimation. The total calculation of the cost of setup is quite complicated, and varies depending on the different component used. This include, size and amount of batteries. the controller, converter and the type of the solar panels (which itself affect the efficiency). Also if you're referring only to the efficiency of the solar panel (watts/usd), it's also not true. For Renology for example, 200 watts with a 20A controller costs 339 USD from amazon. That's less than 1.5 $/Watt. And that's on the relatively pricey side. You can find cheaper panels on Bangood. Again, the links are included in the guide referenced above.
