I ordered the 100W panel, alone, to try with the battery charger and inverter I already had. This panel is not cumbersome. It is really easy to pack and bring to camp. I was suprized to see how flexible the outer grommet rim of the panel is. Yet, the panel itself is rigid. It's encapsulated in a fiberglass-like material to keep it flat and waterproof. I think the most practical part is the carrying case though. It slips in and out with ease. And the case also has a rigid side to it, so you don't have to worry about other gear breaking the panel when its packed up. On a cool sunny day around 40⁰F, I was producing 24.2V. When some clouds passed overhead, it was still producing 22V. The battery I was charging was almost full, so only 2amps were flowing when I measured it. But I was able to run a Jigsaw off an inverter as long as I needed with just a tiny 8Ah battery used as a buffer. I used the built in stands, which you can easily adjust to the sun's vertical angle. I discovered that laying the panel flat on the ground was my best option when leaving it unattended, so I didn't have to keep adjusting the direction it was pointed to follow the sun. The next time I leave my car at the airport for long term parking, I'm leaving the panel in the windshield to keep the battery topped off. I hope this was helpful.
