Renogy 100W Lightweight Flexible Monocrystalline Solar Panel

The Renogy 100W Lightweight Flexible Solar Panel is a monocrystalline solar panel rated at 100W maximum power output, designed for load-sensitive mounting surfaces where rigid panels cannot be used, including curved van roofs, boat decks, RV tops, and truck camper shells. At 5.3 lbs and 0.1 inches thick, the panel is 75% lighter and 95% thinner than a comparable rigid 100W panel, making it a practical choice for weight-conscious builds and surfaces that cannot support standard framed glass panels.

Built for Surfaces Rigid Panels Cannot Reach

The Renogy 100W Flexible Solar Panel is engineered to conform to curved and uneven surfaces that would make a rigid framed panel impossible or impractical to mount. That flexibility matters in real-world builds: a van roof with a compound curve, a boat deck with camber, or a truck camper shell with a rounded profile all become viable mounting locations. Builders who would otherwise have to forgo rooftop solar, or pay for a custom rack to bridge a curved surface, can instead bond this panel directly to the surface itself.

Weight That Stays Off Your Roof

At 5.3 lbs, the Renogy 100W Flexible Solar Panel adds significantly less mass to a roof or deck than a traditional framed panel. For overlanders managing roof load on a vehicle with a weight-sensitive rack, or for boaters watching displacement, that difference is meaningful across a multi-panel array. The 0.1-inch profile also keeps the panel below the visual and aerodynamic threshold where a rigid panel would create noticeable drag or change a vehicle's roofline.

Weather-Resistant Construction for Outdoor Exposure

The Renogy 100W Flexible Solar Panel carries an IP67 waterproof rating on both the junction box and the solar connectors, making the panel suitable for continuous outdoor exposure including marine environments. The panel is tested to withstand wind loads of up to 2400 Pa and snow loads of up to 5400 Pa. The monocrystalline cell design (36 cells in a 4×9 arrangement) delivers a module efficiency of 15.7% at standard test conditions.

Specifications

Who This Is For and Isn't

The Renogy 100W Flexible Solar Panel suits overlanders, van builders, boaters, and RV owners who need to mount solar on a curved, uneven, or weight-sensitive surface where a rigid framed panel is not practical. It is well-suited for adhesive bonding to van roofs, boat decks, camper shells, and similar structures.

The panel does not include a charge controller, battery, or wiring. A compatible charge controller and deep-cycle battery are required to complete a functional solar charging system. The panel is not rated for foot traffic; walking on the panel can crack the cells. Grommets are intended for stationary (non-mobile) installations only; mobile installations require silicone structural adhesive mounting.

Common Questions

Does this panel include a charge controller or battery?

The Renogy 100W Flexible Solar Panel ships as the panel only, with no charge controller, battery, or adapter cables included. A charge controller is required to regulate current between the panel and a battery, and a compatible deep-cycle battery is needed to store the power the panel generates.

What is the IP rating on the junction box and connectors?

The Renogy 100W Flexible Solar Panel carries an IP67 rating on both the junction box and the solar connectors, making the panel suitable for outdoor and marine environments where exposure to rain, spray, and moisture is expected.

How should this panel be mounted on a vehicle or boat?

For mobile applications such as a van, RV, or boat, silicone structural adhesive applied to the back of the panel is the recommended mounting method for the Renogy 100W Flexible Solar Panel. The six metal-reinforced grommets are intended for stationary, non-mobile installations only. Consult a local contractor for detailed installation guidance.

Can I walk on this panel?

Walking on the Renogy 100W Flexible Solar Panel is not recommended. Foot traffic concentrates pressure on a small area of the panel surface, which can crack the cells and cause permanent damage to the panel.

How do I connect multiple panels: series or parallel?

The Renogy 100W Flexible Solar Panel can be wired in series, which adds the voltage of each panel while keeping current the same, or in parallel, which adds the current while keeping voltage the same. The right configuration depends on your charge controller's input voltage and current limits; both wiring methods can be combined to meet a specific system requirement.

How do I clean the panel surface?

The Renogy 100W Flexible Solar Panel can be cleaned with a non-abrasive sponge and water. Regular cleaning to remove dust, sand, and debris is recommended, as buildup on the panel surface reduces power output over time.
