What is a double glass module?
Double glass module contains two sheets of glass, whereby the back sheet is made of heat strengthened (semi-tempered) glass to substitute the traditional polymer backsheet. With * Corresponding author. Tel.: +86 13776101913; fax: +86 51268961413.
Are double glass modules better than traditional modules?
Compared to traditional modules with backsheet, modules with double glass are stronger and more durable, presenting less degradation due to thermal cycling stress. Results from the thermal cycling test up to 400 cycles show about 35% to 43% less degradation with double- glass modules than with traditional modules with backsheet (Fig. 3).
Why is white double glass PV module more powerful than transparent?
Due to the high reflectance of white EVA, the power of white double glass module is higher than that of transparent double glass module by 2-4%. Double glass PV modules is an area of significant investigation by many companies and institutes in recent years, for example Dupont, Trina, Apollon, SERIS, MIT, Meyer Burger and Talesun.
What is double glass PV module?
Double glass PV module is known as the ultimate solution for the module encapsulation technique. Although double glass modules have many advantages, they are not yet widely used in photovoltaic power plants, for which one important reason is the large power loss due to the transmission of light in the cell gap region.
Why is double glass important for solar panels?
Double Glass is especially important in photovoltaic facilities such as solar power plants and with the expected long service life of modules such as AKCOME, Jinergy or Jolywood. Why solar panels with glass-glassTechnology? Why is solar double glass more durable?
Are double glass modules safe?
In addition, because of less micro-cracks and less moisture ingress, double-glass modules present a much lower risk of so-called “snail track” generation. A double- glass module was designed to pass fire-safety class A certification and UL1500V system voltage certification.
Featured Solar Products
High - Efficiency Photovoltaic Panels
Our photovoltaic panels are at the forefront of solar technology. With advanced cell designs and high - quality materials, they offer exceptional energy conversion rates, allowing you to maximize your solar energy harvest. Whether installed on a residential rooftop or a large - scale solar farm, these panels are built to last, withstanding harsh weather conditions and providing reliable performance for decades.
Advanced Monocrystalline Solar Panels
These advanced monocrystalline solar panels are crafted from single-crystal silicon, which endows them with outstanding electrical properties. They have a higher efficiency in converting sunlight into electricity compared to other types of panels. Their sleek appearance also makes them a popular choice for both residential and commercial installations. Moreover, they are durable and can maintain stable performance under various environmental conditions, ensuring a long lifespan and excellent return on investment.
High - Capacity Lithium - Ion Energy Storage Systems
Our high - capacity lithium - ion energy storage systems play a crucial role in optimizing solar energy usage. Utilizing state-of-the-art lithium-ion battery technology, they can store a significant amount of energy generated by solar panels during the day. This stored energy can then be used during peak demand periods or when sunlight is insufficient, such as at night or on cloudy days. With features like high energy density, fast charging, and long cycle life, these systems provide a reliable and efficient solution for energy storage, enabling you to achieve greater energy independence.
Smart Hybrid Inverters
Smart hybrid inverters are the key to a seamless and intelligent solar power system. They can intelligently manage the flow of electricity between solar panels, energy storage systems, and the electrical grid. These inverters not only convert the direct current (DC) from solar panels into alternating current (AC) for household or business use but also optimize the charging and discharging of energy storage systems. With built-in monitoring and communication features, you can remotely control and monitor your energy system, making it easy to adjust settings and track performance.
Portable Solar Power Stations
Portable solar power stations are designed for on-the-go power needs. They integrate solar panels, energy storage, and inverter functions into a single, lightweight unit. Ideal for outdoor enthusiasts, campers, and those in need of emergency backup power, these stations can charge various electronic devices like smartphones, laptops, and even small appliances. Their portability and ease of use make them a convenient choice for anyone who wants to access clean energy wherever there's sunlight, providing a reliable power source in remote locations or during power outages.
Distributed Photovoltaic Power Station Solutions
Our distributed photovoltaic power station solutions are tailored for various applications, from small communities to large industrial complexes. By distributing solar panel installations across multiple locations, we can make better use of available space and increase the overall energy generation capacity. These solutions are designed with high-performance components and integrated monitoring systems to ensure efficient operation, easy maintenance, and maximum energy yield. They also contribute to reducing the reliance on the main power grid and have a positive impact on the environment.
Micro Inverters
Micro inverters offer a unique advantage in solar power systems. Unlike traditional string inverters, each micro inverter is connected to a single solar panel, allowing for individual panel optimization. This means that even if one panel is shaded or has a lower performance due to some reason, it won't affect the overall output of the entire system. They are easy to install, highly efficient in converting DC to AC power, and provide better flexibility in system design, making them suitable for both residential and small commercial solar installations.
Roof - Integrated Photovoltaic Power Stations
Roof - integrated photovoltaic power stations combine the functionality of solar power generation with the aesthetics of building design. These stations are custom-designed to fit directly onto rooftops, replacing traditional roofing materials in part or in whole. They not only generate clean energy but also enhance the overall look of the building. With advanced installation techniques and durable materials, they can withstand the elements while providing a long-term and reliable source of electricity, making them an ideal choice for both new construction and retrofit projects.
