ETFE Laminated
Solar Panel

Small solar panels are widely used in portable electronic devices.

New things comes out like solar robotic cleaners and solar pool skimmers which works in extreme environment as there are a lot chemical materials surrounded them which may corrode, rust or damage the solar panels. A new product then was designed to meet their requirement, which calls ETFE laminated solar panel, till now it is the most durability solar panel to against any harsh environment.

Below are the main features of the ETFE material.

1.ETFE  is a high-strength fluorine polymer that is corrosion and stain resistant, non-stick self cleaning, and retains its clarity (and therefore light transmittance) ensuring long service life for solar panels.

2.ETFE is robust and unlikely to degrade from exposure to environmental pollution, harsh chemicals or extreme temperature variations increasing the longevity on solar panels.

By using this special ETFE material as a top layer of a small solar panel,  it ensures the quality of the solar panel  and quality of pool cleaner.

There maybe some new innovated consuming items required to be powered by solar panel in different conditions, and we believe solar man like us will design and give the most suitable solution to match up these new items and provide them with durable, less expensive solar panels.

ETFE solar panel also powered some fantastic devices which provides tracking and relays critical information for containers, vessels, trailers, buoys and barges. This self-contained device uses solar-powered technology to self-charge, allowing Bluetooth or other sensors to communicate and deliver messages over a longer lifetime.

The choice of materials that will cover the solar cells is the most important aspect in ensuring the lifespan and the mechanical properties of the panel.

As you can see from below photo, there are not many layers of cell protection for the solar panel, the base one is the EVA, a very common material in the industry, which is used in solar cell encapsulation through a thermal lamination process of the cells to make them completely isolated from any contact with water, powder, dust.

We need to find a material to guarantee a high durability of the product for meet strict resistance requirements like sea side. While trying to preserve the flexibility and compactness of the panel, a ETFE outer protective layer is a better option.  ETFE is a fluorine-based plastic. It was designed to have high corrosion resistance and strength over a wide temperature range.  ETFE has a relatively high melting temperature, excellent chemical, electrical and high-energy radiation resistance properties.

ETFE is also self-cleaning (due to its nonstick surface) and recyclable.ETFE has an approximate tensile strength of 42 MP with a working temperature range of −185°C to +150°C. ETFE are resistant to ultraviolet light.

With above advantages like durability, self-cleaning, high light transmission and UV resistance,  The ETFE solar panel will be a priority solution as a clean energy sourcing to give consistent power to charge your electronic devices without worrying of the lifespan.
