PV magazine presents the energy yield results from the outdoor test site in Xi’an,China, that was built in cooperation with CEA, this week. The results show bifacial modules outperforms and energy yield gains of the znshine Gra-polysilicon module excels in many polycrystalline products.
In order to verify the energy gains of Gra-poly modules under different conditions, Znshine entrusted third-party PV MAGZEINE designated laboratory to install modules and record performance in August.
A test was set up between three Znshine modules and other modules, of two graphene-coated modules (ZXP6-60-275/P), one is cleaned weekly while the other is not cleaned at all. An uncoated module (ZXP6-60-265/P), which is not cleaned, was installed as a reference. The result shows that Znshine Gra-poly modules achieve the best-performing among all poly products in the test and 1.1% energy yield boost from the coated module. As the dust continues to accumulate over time, it is expected that the energy yield boost will grow.

Znshine bifacial p-type PERC can greatly increase energy yield and drive down cost, owing to extra power generation on the rear side. in snow, water and other places, and even the ordinary ground with reflected light, it is sure to increase the power generation.
Znshine solar graphene-coating Module is installed a thin layer of graphene, which is made of a single layer of carbon atoms, allows light to pass through more efficiently with better efficiency in converting light to electricity. It’s excellent light transmittance, super hydrophobicity and unique self-cleaning capacity made its power output higher.
In recent years, the rapid development of solar photovoltaic (PV) technology has been accompanied by the continuous iteration of solar cell sizes. From the early 156mm era to today’s widespread use of larger 182mm and 210mm cells, each technological advancement has driven improvements in module power and optimization of system costs.
Graphene is hailed as the most revolutionary material of the 21st century, earning the title of "king of new materials" due to its exceptional properties. Composed of a single layer of carbon atoms arranged in a honeycomb lattice, graphene exhibits a range of remarkable physical characteristics. It is 100 times stronger than steel and has excellent electrical conductivity, with its carrier mobility at room temperature being approximately 10 times that of silicon. Additionally, graphene boasts outstanding thermal conductivity, with a thermal conductivity coefficient of up to 5300 W/mK, far surpassing most materials. Graphene is also nearly transparent, with an absorption rate of just 2.3% in the optical range. It retains excellent flexibility, allowing it to bend and deform while maintaining its structural integrity. These unique properties make graphene a material of enormous potential across various fields and are widely believed to herald a materials revolution.
When purchasing solar modules, performance and price are the two key factors to consider. The performance of a solar module depends not only on its photovoltaic conversion efficiency but also on the strength and durability of its structure. As a crucial support and protective component, the frame material has a direct impact on the overall performance of the module. Additionally, solar module frames, being high-value auxiliary materials, play a significant role in the module’s total cost structure. For instance, *the commonly used aluminum frame, with its strong mechanical properties, accounts for around 13% of the total module cost—surpassing other auxiliary materials like EVA, glass, backsheets, and solder ribbons—second only to the 55% cost share of the solar cells themselves.
Installing a solar photovoltaic (PV) system on a roof is a crucial process that requires ensuring the system efficiently captures solar energy while maintaining its safety and stability. This article will describe how to use the SRS (Solar Racking System) to install PV modules more securely and efficiently.
Una célula fotovoltaica es algo relativamente sencillo. Un material semiconductor, en el que se ha creado un diodo (se le ha dado polaridad), al que se le pone una capa azul antirreflejante y se conectan unos conductores eléctricos para extraer la electricidad. Digamos que la arquitectura de la célu
The first bifacial photovoltaic cells were created in the laboratory several decades ago. The first company that commercialized them was the Spanish company Isofoton (1981), based on the studies of Antonio Luque at the Institute of Solar Energy in Madrid.Today’s bifacial solar modules are a simplifi
Double glass photovoltaic modules stand out with remarkable advantages in power generation, embodying authenticity in their performance. The transparency and robust UV resistance of glass seamlessly align with the characteristics of double-sided cells, establishing a flawless synergy. When it comes to the module backsheet, the industry widely acknowledges the superiority of glass backsheets. In 2018, Joshua S. Stein from Sandia National Laboratories and Dirk C. Jordan from the National Renewable Energy Laboratory (NREL) conducted an in-depth review of double glass photovoltaic modules, delving into various pertinent issues.
Recently, ZNSHINE SOLAR, through its Singapore subsidiary ZNSHINE ENERGY INVESTMENT PTE LTD, officially launched a 549.26 kW solar project in the Bandar Baru Bangi area of Malaysia. This project will provide commercial and industrial rooftop solar support for the Malaysian factory of Japan’s Okumura Metal. Situated near Kuala Lumpur, Malaysia’s capital, the project marks a significant step in ZNSHINE SOLAR's strategic development in Southeast Asia’s green energy market. It also serves the solar rooftop needs of multiple Japanese corporations with overseas factories, demonstrating ZNSHINE SOLAR’s unique advantage in supporting global enterprises in their green transformations.
