If its got 5 contacts then its either dual or triple power supply/ Like one is 5v one 12v and one 3volt. Then 12v ground and 3+5v ground on same line. This is only a example but the point is Im sure it uses more than one power feed. Your best bet is to find a spec sheet on it and find out what the pin-outs are. Also use a good PSU as the original ones for the panels are regulated very well like a psu for a pc. If you get any voltage spikes it can kill the panel due to sensitive electronics. So select the psu carfully with that in mind.
