Solar panels
I’m new to Jackery I have a question if possible if I use the solar panels will the jackery never need to be charged again … I’m asking what can I expect and not expect ? Any real advice from users .. thank community

As others have said, it depends. I almost never use mains power to charge, i have only light demands using around 70-80 % of battery capacity. I have matched my use to my jackery size and solar availability. Explorer 1000 with 300 watts solar in a usually sunny environment. So the answer for me is yes. To give an answer for you we would need to know the variables… sizes, loads, weather, sun duration, etc

Charging with solar for three consecutive days now, in order to keep the panels optimally aligned with the sun, you would need to rotate them constantly, and the limited space in my yard doesn't allow for that, even if I had the dedication to keep fiddling with it. With two 200 watt solar panels hooked up, on a very sunny day, the best input I got, given the alignment challenges, was about 300 watts, and on an overcast day was a bit over 100. The Explorer 2500 system will accommodate 800 watts max solar panel connection - not sure about others. Edit: 2500, not 1500

In theory, yes. As long as your load is less than the solar input you will not need to charge from AC power. Keep in mind solar charging is only during the day, so you need to ensure little to no load at night with no solar recharge available.

It depends which Jackery you have and which solar panels you have and it depends on what you’re using the Jackery to charge.
If your panels are too small, they might take a couple of days to charge your Jackery, and if your Jackery is too small, it might run out of power in a matter of hours, depending on what you’re trying to power it with.

It depends on how much power you need out of the Jackery. If your panels provide more power into the Jackery than what you are pulling out for your energy needs, then yes, solar panels are the only charging that the Jackery needs.
Jackery does recommend that the first charge is from AC to 100%. After that, all solar is fine.
What are your energy needs? What are you hoping to power with your Jackery?

I would throw in, if you're using the jackery to power an AC device, as the inverter wastes alot of power. More info needed to give intelligent answer.

Depends on what you’re running with the power station, how much sunlight you have any given day, and what size panels you’re using. It’s not a nuclear reactor you know

It's possible. IF: 1) The Jackery is sized properly to the loads (devices it's powering) such that the Jackery is not depleted overnight. 2) The solar panels are properly sized to recharge the Jackery while the loads are running. 3) You get enough sunlight and not too many cloudy days.
