ZKFN SOLAR lightweight photovoltaic modules are a new generation of flexible crystalline silicon PV modules developed and manufactured by a high-tech enterprise incubated by a research team from the Chinese Academy of Sciences. They adopt revolutionary flexible encapsulation technology, achieving a perfect combination of lightweight design, flexibility, and high reliability.
The power generation principle is the same as that of traditional photovoltaic modules and is based on the photovoltaic effect. When sunlight strikes the module surface, photon energy is absorbed by silicon crystals to form free electrons and holes. Under the action of the PN junction, a voltage is generated, and when connected to an external circuit, current is produced.
They feature extreme lightweight design (only 2.9~5.9 kg/m²), excellent flexibility (bending radius of 0.3 m), revolutionary anti-microcrack technology (hail-resistant and walkable), outstanding wind and snow load resistance, and comprehensive environmental adaptability.
They are widely used on weight-restricted commercial and industrial color steel tile rooftops, TPO/PVC waterproof membrane roofs, curved/special-shaped buildings, BIPV building-integrated photovoltaics, as well as in mobile energy applications such as RVs, yachts, and portable systems.
Their weight is only 20%–30% that of glass modules, eliminating the need for costly roof reinforcement. They support direct adhesive installation or lightweight clamp installation without racks, greatly improving construction efficiency while avoiding damage to the original waterproof roof layer.
They use high-efficiency monocrystalline silicon cells (PERC or TOPCon), and the maximum module conversion efficiency can exceed 23.5%, consistent with the efficiency of mainstream conventional glass modules.
It has passed TÜV, CE, and CQC certifications and complies with IEC 61215 and IEC 61730 standards. It has also successfully passed extreme condition tests including a 25 mm hail impact test, a Level 17 wind tunnel test, and a 5400 Pa mechanical load test.
The core technology is TSR-Armor™ three-dimensional multiscale synergistic reinforcement technology. Through nano-scale graphene oxide, micron-scale fiber reinforcement layers, and a macroscopic high-strength resin matrix, it provides brittle solar cells with an “invisible armor.”
The designed service life exceeds 25 years. We provide a 15-year product material and workmanship warranty, as well as a 30-year linear power output warranty, backed by PICC insurance.
Yes. Although solar irradiance decreases in rainy or smoggy weather and power generation will be reduced accordingly, the modules can still capture diffused light for photovoltaic conversion and generate a certain amount of electricity.
Photovoltaic modules themselves convert light energy into direct current and do not generate high-frequency electromagnetic radiation. The electromagnetic radiation generated by electrical equipment such as inverters is also strictly controlled within national safety standards and is harmless to the human body.
Installation is very convenient. The flexible series (SolarVela) can be directly bonded using special structural adhesive for photovoltaics; the lightweight rigid series (SolarPega, SolarNoah) can be fixed non-destructively with dedicated clamps. Neither requires heavy mounting structures.
For flexible modules, installers need to master the standard adhesive application process for structural adhesive. For the lightweight rigid series (SolarPega), since they are walkable, installers can directly work on the modules wearing soft-soled insulated shoes, greatly reducing installation difficulty.
They are highly suitable for low-load, large-span factories, curved or wave-shaped special roofs, glass skylights, and TPO/PVC membrane roofs with very high waterproofing requirements.
The safe operating ambient temperature range of the modules is -40°C to +85°C, enabling them to adapt to the extreme cold and heat conditions of most regions.
ZKFN SOLAR lightweight modules use flame-retardant composite encapsulation materials, and their fire performance reaches UL790 Class C and above, meeting the fire safety requirements for building rooftops.
Thanks to TSR-Armor technology, the modules have passed rigorous hail resistance testing (25 mm ice balls impacting at 23 m/s). EL inspection shows no microcracks and zero power degradation, thoroughly solving the pain point of traditional lightweight modules being easily damaged by hail.
Very convenient. Models installed with clamps can be directly loosened and replaced; for models bonded with structural adhesive, a single module can be removed and replaced without damage within 30 minutes using specialized adhesive removal tools.
The module surface has a super-hydrophobic self-cleaning function, and normal rainfall can remove dust. If manual cleaning is required, it is recommended to use a soft brush and clean water. For the SolarPega lightweight rigid series, O&M personnel are allowed to walk directly on the modules wearing soft-soled shoes for cleaning.
The surface uses highly weather-resistant fluororesin material and features a frameless design. It has passed IEC salt mist (Level 6) and enhanced ammonia corrosion tests, making it very suitable for coastal areas and heavily polluted industrial plants.
