The Renogy folding setup gives you a lot more options for when and how you use it. It's worth the price premium IMAO.
I bought a defunct-brand folding panel with PWM much like the Renogy and built a locking roof rack / tray where the panels rides and functions all the time. And when needed I can readily dismount it and set it up away from the shaded vehicle into full sun, on a 25'+ lead.
