hello! I have been given and old solar panel and I want to use it to charge up my leisure battery while I'm away in the van. I have no idea about what connections or cable I need for it. Any advice would be great.

+ is positive. - is negative. with the panel connected and in sunlight, you should read >12V on these 2 terminals.

Tel is right there is a socket connection missing for the + connection. You could probably adapt something to fit, but I would look on eblag for solar pv connector due to the amps that could go through it in full sun with a heavy load on. ( depending on how big it is and it's output)
You will probably need some cable and a charge controller as well to make it all work!

cheers for the reply! Ye I no there's a + socket connection missing can I not just buy one? If not how could I adapt something to fit? I have a charge controler on its way I bought it before I took the back off and realised one of the conections wasn't there! Any advice is good I'm new to all this solar business.
