The answer depends mostly on how much air conditioning you consume. If you use a large central AC, a solar system could easily cost you 100,000 USD or more. If you use AC responsibly, it could be as little as 8,000 USD.
Louaizeh: 3.3kwp solar panels, 5.12kWh batteries.
Very simply, it is the total amount you spend on an electricity generating system over the course of its lifetime divided by the amount of electricity you get.
For example, how much you spend on fuel, maintenance, and replacement parts for a diesel generator divided by how much electricity it gives you.
Generators are about $0.30/kWh. Solar is about $0.05/kWh.
The price of solar panels has been declining rapidly for years, to the point where they are almost free.
But over the past 3 years, the price of LifePo4 batteries – batteries that last 3,000-5,000 cycles or 10 to 15 years – has crashed as well.
This makes the levelized cost of solar + batteries the cheapest 24/7 electricity available commercially.
In fact, no. Lebanon is one of the richest countries in light – and remember that solar runs on light not heat. About 25-30 m2 is sufficient for an average house.

A lot of people ask about the difference between amps and kilowatt hours (kWh).
4.55 amps = 1 kw.
So if you use 4.55 amps for one hour, you have used 1 kWh.
As you might know, inverters transform the sun's rays into usable electricity (DC to AC). But which inverter is best for you? There are three main types:
Clearly, hybrid inverters are the future.
Yes. It can power air conditioners, washing machines, refrigerators, and water pumps. It can power electric cars and buses. It can (and even does) power oil rigs.
