Customization of
Flexible Solar Panels

Customized flexible, lightweight solar panels – ideal for application where weight and form of construction are critical factors, such as mobility, marine or custom lighting applications. Semi flexible solar panel technology allows to produce curved panels without breaking the high efficiency crystalline silicone solar cells.

Customization process

While every customer is different, our team typically follows a four step development process:

1. Exploratory Discussion
Typically a combination of phone and email conversation so we can learn about your project specifications and timeline.

2. Panel Specifications and Design
You will help us specify voltage, power, dimensions, materials and mounting mechanism and we will provide one or more designs that meet your requirements.

3. Prototype
Once a panel design is approved, we will produce prototypes for testing. Cost varies.

4. Full Production
Once fully tested, full production begins.

Selection of Power Supply and Voltage

Choose the right one

Total power is determined by surface area. We most frequently use 19% efficient monocrystalline cells which provide about 0.019 Watts per square centimeter or 0.12 Watts per square inch.

For example, the solar cell sections on this 2.2 Watt panel measures approximately 4in x 4.8in, adding up to 2.2W.

Selection of Coatings

Choose the right one

Urethane

Highly UV resistant, but heavier than ETFE. Our standard panels have a urethane coating and last up to 10 years in the sun with minimal power degradation. The urethane coating is poured or "potted" on the solar cells and leads to a highly waterproof panel. Each individual cell is completely encapsulated by the urethane.

ETFE

Slightly less UV resistance than urethane, but lighter weight. ETFE and EVA are attached to the cells via a lamination process. With high quality materials (there is a difference in the production quality of ETFE and EVA), these panels have an expected life of 5 years outside.

Epoxy or PET

Panels made with these coatings will be inexpensive, but we don't recommend this coating as it tends to have a relatively short lifetime. They are the least UV resistant of any of the options.

Glass

Most UV resistant, but also the heaviest and can be challenging to mount in a streamlined manner.

Substrate selection

Choose the right one

Cell

The solar cells are mounted on a substrate or backing. Again, there are several options.

Aluminum-Plastic-Aluminum

Very high strength to weight ratio material used in commercial building applications. Easy to create waterproof panel. Allows embedding of screw or nut into substrate.

PCB Plastic

Different thicknesses available, from 1mm to 5mm depending on requirements. Allows embedding of knurled nut into substrate. Higher density than Aluminum-Plastic-Aluminum substrate. Not waterproof without additional hardware.

Aluminum

Typically the strongest substrate option, but is also the heaviest. Thin and rigid.

Wire specification

Our standard wire has strain relief is about 12 inches long and terminates in a 3.5x1.1mm plug. This can be changed to whatever length and terminal you prefer. The wire can be embedded into the substrate to keep it waterproof or soldered on the outside of the panel. Power and ground wires can even be separated as shown below.
