wired the panels in parallel.
LEDs will blow if the maximum current is exceeded. But if you have a long string of LEDs and they have enough bulk resistance, it can work for a while. Furthermore, many wall warts have current limiting. So people can and do connect their LEDs directly to wall warts and they do work OK for a while. It is still bad form.
with no resistor the LEDs for sure will blow, DUH!
