AIKO ETFE Solar Panels Series - Flexible and lightweight, semi-flexible modules designed for situations where a traditional framed panel is simply impractical. A key advantage is the ETFE coating - resistant to UV radiation, salt, and harsh conditions, while also allowing better light transmission than popular PET laminates. This ensures that the modules maintain their aesthetics and stable performance for longer, even in challenging outdoor environments.

The use of modern back contact monocrystalline solar cells allows for minimizing losses due to shading and improves efficiency, which is crucial when every square centimeter counts. The flexible design makes installation on slightly curved surfaces easier - without heavy frames and without lifting the roof load.

This solution is ideal for users who need power outside of a standard installation: campers, boats, off-grid setups, roofs with limited load-bearing capacity, as well as mobile projects. Compared to the competition, this series stands out due to its greater laminate durability, improved environmental resistance, and easier integration on unconventional surfaces.

What owners get
Dominant flexibility within the segment

With an efficiency of 18.73-19.22%, this series outperforms its direct competitor in the flexible class - DMEGC GH400M10T-B48HST (15.48%) by more than 3.7 percentage points, which translates to approximately 24% more energy generated from the same surface area on a camper or boat.

ETFE Laminate - Premium Grade

ETFE (fluoropolymer) maintains high light transmission and UV, salt, and moisture resistance for over 20 years of operation without yellowing, unlike popular PET laminates used by budget-conscious manufacturers of flexible panels. It is particularly important in marine and off-grid environments.

BNEF Tier 1 - fully bankable

AIKO has maintained BNEF Tier 1 status since Q3 2025 (verified by BNEF Tier 1 Methodology, March 2026), placing it among the top 2% of over 17,000 manufacturers. This ensures access to bank financing for projects and provides credible 25-year guarantee options.

25-year linear warranty on power

The manufacturer guarantees stable power output for 25 years, which is the standard for high-quality rigid panels. In the flexible segment, where many competitors only offer 10-year performance warranties, this is a significant advantage when calculating the total cost of ownership (TCO) for off-grid installations.

Back-contact PERC - reduced shading losses

The design of back-contact cells (electrodes on the rear) eliminates metallic busbar shadows from the front of the cell and reduces partial shadowing losses - which are crucial on irregular surfaces (e.g., camping roofs, boat decks), where perfect panel alignment is impossible.

Trade-offs
PERC technology - higher LID degradation

Monocrystalline PERC cells exhibit a higher Light Induced Degradation (LID) rate in the first year of operation compared to N-type TOPCon/HJT/ABC. AIKO utilizes ABC technology in its flagship rigid (Neostar, Stellar) modules, achieving >25% module efficiency - however, this technology is not available in the flexible ETFE series format, which represents a technological step backward compared to the company's own product portfolio.

Superior performance compared to similarly powered, rigid competitors

Within a group of comparable products, the 400 Wp series achieves a maximum of 19.22%, while Meyer Burger White achieves 21.7% (+2.5 percentage points), and Solaria PowerXT achieves 20.2% (+1 percentage point). In situations where both rigid and flexible panels can be installed, the difference in efficiency can be a deciding factor in the choice of installation type.

About the ETFE Solar Panels - Flexible series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

What distinguishes the ETFE coating from popular flexible panels made with PET laminate?
AIKO ETFE Series Solar Panels - Flexible panels utilize ETFE film instead of the cheaper PET laminate. ETFE is more resistant to UV radiation, salt, and moisture, which means it yellows and loses transparency more slowly. In practice, this translates to better light transmission throughout the lifespan and higher energy yield per square meter compared to PET panels in a similar price range.
What is the warranty on Aiko ETFE solar panels - flexible?
The manufacturer provides a 12-year product warranty (for material and workmanship defects) and a 25-year linear warranty on power output. Over the 25-year period, the panel should maintain a specified percentage of its nominal power output, according to the degradation curve provided in the product catalog. AIKO is a Tier 1 manufacturer, which ensures the financial stability of the company and the effective enforcement of claims.
Are Aiko ETFE Flexible panels suitable for RVs or boats?
Yes, this is one of the intended applications for this series. The lightweight construction, without a rigid aluminum frame, allows the panel to be directly attached to the roof of a camper or the deck of a boat. The ETFE coating is resistant to saltwater and the harsh marine environment. With a power output of up to 400 Wp, a single panel can power basic off-grid appliances without overloading the vehicle or vessel.
What is the maximum curvature that AIKO ETFE Flexible panels can be mounted on?
The series is designed for mounting on slightly curved surfaces, typical of camper roofs, boat bows, or industrial buildings. The manufacturer does not recommend bending the module beyond the angles specified in the product catalog (usually up to several dozen degrees), as excessive stress can damage the cells. Before mounting on heavily curved surfaces, it is advisable to check the permissible curvature radius in the datasheet for the specific power model.
Do flexible PERC solar cell technology in the AIKO ETFE series perform adequately under partial shading?
The monocrystalline PERC cells used in this series have a higher efficiency than standard polycrystalline cells, but, like any technology, they are susceptible to losses due to partial shading. For mobile installations (e.g., RVs, boats), where the angle of incidence and shading change dynamically, it is advisable to use MPPT (Maximum Power Point Tracking) controllers instead of PWM (Pulse Width Modulation) controllers to minimize losses and improve energy yield under varying conditions.
Can Aiko ETFE Flexible panels be installed without a professional installation team?
For small off-grid installations (e.g., camper vans, boats, mobile homes), installation is significantly simpler than with traditional panels. The absence of a frame and the low weight make it easier to attach or mount to a surface. However, proper electrical connection, cable selection, safety devices, and a charge controller require basic electrical knowledge or consultation with an installer, especially for systems with power outputs close to 400 Wp.
