Can 10W solar panel keep a car battery charged or topped up? How do you connect it?

Is a 10W solar panel enough to charge a car battery in the UK? How do you connect a solar panel to your car battery and does it charge it?

If you want to know the answer to these questions, this video is for you.

Car batteries are pretty expensive and despite all the warranties that they last 5 years, I have never had a battery that lasts that long. Most of the times is that they are left standing for too long and the voltage drops and you can do that very few times. The optimal is if you keep the battery topped up.
The best way to do that is through a solar panel. I wanted something fairly cheap, but relatively powerful. So I bought ECO-WORTHY 10W solar panel. This includes the 10W solar panel, crocodile clips for the car battery and auxiliary SAE plug. The solar panel comes with an SAE connector at the end.

This test was ~1 month test. First charging the battery with the Noco Genius 5 charger, then leaving the battery for 1 day, so the chemistry settles. Then I will leave the solar panel facing West for 20 days. Of course the solar panel is connected to the battery. The car battery measurements were done with Foxwell BT100 Pro car battery tester. I have a review of this battery tester here:    • Car battery tester review (Foxwell BT100 Pro)  

Also, I am using a straight SAE connector and an OBDII to SAE adaptor.
