Can I modify outdoor lights to be solar-powered, with a night/day on/off switch?

Hi Everyone,

I'm new to the forum, and have a question about solar lighting for an outdoor garden. So, I apologize if this is in the wrong place. "Electrical" seemed like a good place to start. Basically, I'm wondering if it's possible to modify these lights:

I got a handful of boxes of them for free, and I'm wondering if it's possible to convert them to solar using a combination of this panel, and this on/off switch:

PANEL:

SWITCH:

I tried to match up the 5W power on the panel and the light strings, and I'm wondering if any outdoor switch would do. Ideally, I'd be able to hang them in my garden, let them charge during the day, and come on either at night (maybe with a light/dark sensor?), or by pushing that switch.

Is it possible to connect multiple strings of these lights in sequence to one another? Or would each string require its own power source/switch?

If anyone is up for explaining to my why or how this would or wouldn't work, I'd appreciate it. In my head, I'm thinking: "Yeah, this makes sense." But, I know that there's always a part of projects like these that I overlook.

Thanks so much for your help!

Can you? absolutely, would it be worth it?
One of the rules of solar is it's immensely easier and cheaper to use less power than to buy more solar.
"This incandescent light bulbs normally runs for 1000 hours, if you need more spare bulbs, pls search B00R25V92Y for replacement bulbs. If you prefer long lasting bulbs, pls search B01J3RP90G for led replacement bulbs. "

Those are by default incandescent. Your solar requirements for that are maybe 6x as expensive as just buying LED ones. Are you against LED for the look? (asking before I do more work on research and math)

Either way, your switch will have to match ac vs dc of the lights, as well as be somewhat near the amp or watt requirements (amp * volt) if DC (just for efficiency)
