Zamp solar manufactures their own USA made panels, made in Bend, like the ZS-US-160-30A-DX (160 watt deluxe solar kit), up to the 480 watt kit. Zamp has changed the part numbers and no longer uses ZS-320-30A-DX, instead they use the 160 watt US deluxe kit plus an expansion panel kit like ZS-US-EX-160-DX to complete the 320 watt kit, up to their 480 watt kit.
We do have a mix of the portable solar kits listed separate from the ZS-US-40S-P, ZS-US-80-P, ZS-US-120-P, Z-US-160-P and the ZS-US-200-P. We also have some of the previous generation models available in the ZS-160-P, and the ZS-200-P. The ZS-40-P is no longer available, and has been replaced with a single panel 40 watt ZS-US-40S-P. All generations have the latest upgrades, including the new stronger legs, and a handle back on the frame itself.
