DOKIO 100W 18V Flexible Solar Panel Monocrystalline for 12V Battery Charging, Semi-Flexible ETFE Lightweight with MC4 for RV Marine Boat Camper Van Trailer Off-Grid Power

【Ultra-Light & Thin】 Only 2.3 lb and 0.03 in thin—lighter than conventional glass panels. Easy to carry, hang, or move for mobile off-grid power. Best for travel, camping, and seasonal use, not a permanent roof replacement.
【Flexible up to 30°】 Safely bends to a 30° arc to fit curved or irregular surfaces on vans, campers, trailers, boats, and tents. Avoid over-bending or stepping on the panel to keep performance intact.
【Safety-Focused Installation & Cooling】 Leave ventilation space so heat can escape. Do not mount directly on combustible materials (e.g., wood, asphalt shingles, fabric, foam). Avoid trapping heat or running cables beneath the panel.
【Safe Use Tips】 Built-in bypass diodes reduce power drop in shade. For reliable use, always pair with a PWM/MPPT controller and avoid continuous heavy loads that exceed the 100W rating.
【Series or Parallel Expansion】 Wire panels in series for higher voltage or in parallel for higher current—MC4 connectors make it easy to build larger 12V/24V systems with a proper controller.

FAQ:

Q: How big is the renogy 100W flexible solar panel?

A: The Renogy 100W Flexible Solar Panel is anything but traditional. Perfect for marine use or placement on top of a van or vehicle, the Renogy 100W Lightweight Solar Panel is thin and capable of flexing up to 248 degrees. At 4 pounds, this flexible solar panel weighs only a quarter of its traditional 100W counterpart.

Q: Is the Flex solar panel easy to use?

A: The flex panels are also very thin and light so there is almost no extra weight added to our little lighter weight trailer. The Solar Kit comes with a solar controller panel which is very simple to understand and operate (it has two buttons and a screen, simple!).

Q: What is the efficiency of a 100 watt solar panel?

A: From a standard 100 watt panel, it’s common knowledge that you will get about 75% efficiency (75 watts) due to resistance/etc, that’s just the way things work. However, I was surprised to see that I was getting 84% efficiency (84 Watts) in direct Florida sunlight!
