Pros
  • One 200 W sheet for about 57 cents per watt, cheaper than most name-brand flexible panels
  • ETFE surface usually holds up better in sun than PET
  • Pre-drilled mounting holes allow fixing it without relying only on adhesive
Cons
  • The listing publishes no voltage, current, weight or warranty, which makes sizing a charge controller guesswork
  • Sold by a little-known store with few reviews
  • No independent output test
