Choosing a solar panel for camping, RVs, or backup power often comes down to wattage versus flexibility. The EcoFlow 175W Solar Panel and the EF ECOFLOW 100W Flexible Solar Panel are two EcoFlow options with different trade-offs. The 175W panel is built around higher output and a 25% conversion rate, while the 100W flexible panel is built to bend around curved surfaces and weigh less. Your main decision is whether you need maximum power from one panel or a panel that can conform to an irregular roof.
Quick verdict
If you need more watts per panel and you have a mounting surface that doesn't require flex, choose the EcoFlow 175W Solar Panel. If you need a lighter, flexible panel for a curved RV or van roof, the EF ECOFLOW 100W Flexible Solar Panel offers a lower listed price and easier placement.

| Current type | AC/DC | DC |
Where each product wins
- The EcoFlow 175W wins on output, with 175W and up to 25% efficiency.
- The EF ECOFLOW 100W wins on portability, weighing 5.1 lbs and flexing up to 258 degrees.
- The EF ECOFLOW 100W also has the lower listed price of the two.
Product notes
EcoFlow 175W Solar Panel 25% High-Efficiency Solar Modules for Outdoor Camping
The main draw here is output. This panel is listed at 175W with conversion efficiency up to 25%, and its MPPT charging mode helps manage the power going into your system. It is intended for Class B vans and home photovoltaic systems, with a shortened length of 46.3 inches to fit a van roof. The listed price is higher than the flexible panel, so it makes sense when you want more power from a single panel and you have a mounting surface that doesn't require flexibility. If you need a panel that can curve around a rounded roof, the flexible option is the one to consider.
EF ECOFLOW 100W Flexible Solar Panel with High Efficiency Solar Modules, IP68
This panel is built for curved surfaces. It weighs 5.1 lbs, flexes up to 258 degrees, and uses 182 monocrystalline silicon cells made with advanced glass fiber, making it 70% lighter than traditional solar panels. It lists a solar connector and DC output, so it pairs naturally with portable power stations or a Power Kits system. The product title also includes IP68. The trade-off is output: 100W at 23% efficiency, so it will generate less power under the same sunshine. Choose it when you need to fit a curved RV roof or want a portable panel that is easier to move around, especially if you prefer the lower listed price of the two.
Final choice by use case
- For a Class B van roof or a spot where you want more watts per panel: EcoFlow 175W Solar Panel 25% High-Efficiency Solar Modules for Outdoor Camping.
- For a curved RV/van roof or a portable panel that can flex: EF ECOFLOW 100W Flexible Solar Panel with High Efficiency Solar Modules, IP68.
- For the lower listed price of the two, the EF ECOFLOW 100W Flexible Solar Panel is listed at USD 211.25.
