You can! Grab the Redarc Parallel Cable Kit # RED78VR. It lets you combine both MC4-based panels safely into a single input. We helped a couple in Kansas City daisy-chain two 200w kits to keep their 12V fridge and LED party lights running from morning kickoff through post-game cleanup. Just be sure the controller can handle the total wattage.
For example, you'll need to make sure your controller is rated for at least 30A to handle 2 of the Rich Solar Mega 200 Portable Solar Panel with Case - MC4 Connectors - 200 Watts # RS85FR or a 40A controller for 2 of the Rich Solar Mega 250 Solar Panel 250 Watts # RS35FR.
