What is a simple way of connecting a PV panel to a battery to a set of lights?

Hi. I’d like to hook up a small (40-50 watt) solar panel to a battery (like a car battery) to a few LED lights (less than 10 watts). I’m not interested in powering my own home at this point, just making a sort of set-up that allows me to experiment. I’m looking for advice on how to best do this, but I don’t want to buy a kit. I think I know how to calculate my watt-hours, but I’m fuzzy on AC/DC power, and whether to buy a PV panel or make my own from some solar cells. Are a charge controller and inverter necessary? I’d like to do this as cheaply as possible (under 200 USD)- any suggestions from your experiences? It’s complex, so web page links are fine; ones with pictures and diagrams would be useful since I’m a visual learner. Thanks in advance.
