Specifications

It is important to only connect matching solar panels in parallel.

Some people recommend to use a blocking diode when connecting non matched panels in parallel. However if you do put a blocking diode in then only the panel with the higher voltage will provide electricity to the system at any given time. The other diode will be off (reverse biased) and no power will be produced from that panel at all. A blocking diode should be used in the positive output to the  controller if the controller does not include one internally. All LUX Solar controllers include a blocking diode.
