Outdoor Lantern Solar Solution needed

[The Pool Man]

Greetings,

I've been all over Amazon and AliExpress looking for a type of product that boils down to an LED bulb connected to a solar panel. Almost all options are a dim bulb with a tiny solar panel.

I don't understand is why someone doesn't offer way brighter bulbs with a way bigger solar panel. (Is it a battery storage issue?)

So I visit here under the presumption I may need to hire an electrician to 'make' the product I'm seeking. That is: I take a lantern and bulb combo I already use and juice it (somehow) with a larger solar panel.

I'm going to include links to my bulb and lantern. I must stick with these because I'm in a condo complex using only this fixture. (What I'm doing is adding a lantern where no electricity ever was set up.)

This is not spam. It's just so that anyone who has spec questions can simply go to the links.

So I'm looking for a way to set up a large enough solar panel/battery/convertor situation to power this.

In this picture I show where I'd like to run the exposed wiring.

The panel would run to a California rooftop typically bathed in light.

So is this possible? And reasonably affordable?

Any help would be greatly appreciated.
