What Are Flexible Solar Panels?

Flexible solar panels are lightweight, bendable photovoltaic modules that can conform to curved surfaces. Unlike traditional rigid panels with aluminum frames and glass coverings, flexible panels use thin-film technology or specially manufactured crystalline silicon cells encased in polymer materials that allow them to bend without breaking.

These innovative panels typically weigh 70-80% less than conventional solar panels, making them ideal for applications where weight is a concern. Their ability to flex up to 30 degrees (and some models up to 248 degrees) allows for installation on curved surfaces that would be impossible with traditional panels.

While traditional panels excel in efficiency and longevity, flexible solar panels offer unique advantages in portability, installation versatility, and applications where weight and form factor are critical considerations.

How Do Flexible Solar Panels Work?

Flexible solar panels operate using the same photovoltaic effect as traditional panels. When sunlight hits the semiconductor material within the panel, it excites electrons, creating an electric current. The key difference lies in their construction.

Construction Technology

Most flexible panels use one of two technologies:

Thin-film solar cells - Photovoltaic material is deposited directly onto a flexible substrate like plastic or metal foil
Crystalline silicon cells - Ultra-thin monocrystalline or polycrystalline silicon wafers are embedded in flexible polymer materials

The cells are encased in durable, weather-resistant materials like ETFE (Ethylene Tetrafluoroethylene) or PET (Polyethylene Terephthalate) that protect the cells while allowing flexibility.

Tools and materials needed for flexible solar panel installation

Installation Steps

Plan Your Layout
Measure your installation surface and determine the optimal placement for your panels. Consider shade patterns throughout the day and proximity to where the wiring will enter your vehicle or structure. Mark the positions with a pencil or removable tape.
Prepare the Surface
Thoroughly clean the mounting surface with isopropyl alcohol to remove any dirt, grease, or contaminants that could affect adhesion. Allow the surface to dry completely before proceeding.
Create an Air Gap (Optional but Recommended)
For optimal performance, create a small air gap (1/4" to 1/2") between the panel and the mounting surface. This can be done using spacers at the corners or a frame. This gap helps with cooling and can extend the life of your panels.
Attach the Panel
Apply VHB tape or industrial adhesive to the back of the panel (or to your spacers if using them). Carefully position the panel according to your markings and press firmly to secure. If your panel has grommets, you can alternatively use screws for mounting.
Wire the System
Connect the positive and negative wires from your panel to your charge controller. The charge controller should then connect to your battery or power storage system. Use cable management clips to secure wiring and prevent strain on connections.
Test the System
Once everything is connected, test your system to ensure it's generating power. Most charge controllers have indicator lights that show when the panels are producing electricity.

Pro Tip: If installing on an RV or vehicle, consider routing the wires through a refrigerator vent or other existing opening rather than drilling new holes to maintain your vehicle's weatherproofing.
