Efficient Double Glass Solar Modules
High durability, suitable for various climates, offering extended lifespan and excellent energy yields.
Why Choose Double Glass Solar Modules?
Glass-glass solar modules (bifacial modules) increase energy production by approximately 2% to 5% compared to traditional glass-backsheet modules, thanks to their ability to capture light from both sides. They are particularly suitable for high-reflectivity environments, such as white roofs or snowy surfaces. Their dual-glass structure ensures superior durability, extends system lifespan, and reduces maintenance costs. With glass-glass modules, you benefit not only from enhanced efficiency but also from a stable and long-lasting return on investment.

FAQ
Although the manufacturing costs of double glass modules are slightly higher than those of glass-backsheet modules, their increased durability and extended lifespan provide a better long-term return on investment (ROI). Additionally, due to their superior efficiency, double glass modules generate more energy from the same surface area.
The maintenance of double glass modules is relatively low. Due to their robust construction, regular cleaning of the glass surface is usually enough to ensure that dust or dirt does not hinder light absorption.
It is approximately -0.24%/°C (for example, for Maysun HJT modules -0.24%/°C and for Maysun TOPCon modules -0.32%/°C). A low temperature coefficient means that the performance loss at high temperatures is relatively low.
The lifespan of double glass modules is typically 25 years or more, which is longer than the lifespan of most glass-backsheet modules, which is around 20 years. The additional glass layer increases resistance to aging and physical damage.
The efficiency of double glass modules is typically about 2% to 5% higher than that of glass-backsheet modules, depending on environmental conditions and module design. This is because the rear side of double glass modules can reflect light, further improving energy conversion.
A solar panel with damaged safety glass can still function, but two issues arise: First, the protection of the solar cells from moisture is no longer guaranteed. Second, loose glass shards may fall off. It is therefore recommended to replace the damaged module as soon as possible.

Double Glass Solar Module Introduction
Double glass modules use an innovative design with glass on both sides, offering higher photovoltaic conversion efficiency and better environmental characteristics. This structure allows for stable operation under various weather conditions and significantly extends the lifespan of the photovoltaic system. It is suitable for various installation scenarios, particularly in high wind speeds, heavy snow loads, and extreme weather conditions.
Introduction to Double Glass Modules
1. Advantages of Double Glass Modules
Compared to traditional single glass modules, double glass modules offer significant advantages, particularly in terms of efficiency and durability. The rear glass layer can absorb reflected light, increasing photovoltaic conversion efficiency. The double glass design ensures excellent performance in terms of durability, wind and snow resistance, as well as adaptability to temperature variations. It is used in various fields such as commercial, residential, and agricultural photovoltaic applications.
2. Applications of Double Glass Technology
Double glass technology not only enhances the overall performance of photovoltaic systems but also effectively protects against potential-induced degradation (PID) and reduces the degradation rate of solar modules. With the ongoing development of the solar energy market, double glass modules have become an ideal choice in industries, agriculture, and urban construction. For photovoltaic systems requiring efficient energy production and stable long-term operation, double glass modules are undoubtedly the best choice.
3. Performance Parameters of Double Glass Modules
Double glass modules generally offer higher power output and perform particularly well in low light conditions. Their photovoltaic conversion efficiency is typically above 17%, making them suitable for various climatic and geographical conditions. Additionally, double glass modules have a low temperature coefficient, allowing them to better handle high temperature conditions.
4. Durability and Lifespan
Double glass modules are made with high-quality glass and reinforced packaging technology to ensure their stability in extreme conditions. Their resistance to shocks and corrosion is higher than that of single glass modules, and their lifespan typically exceeds 30 years, which far surpasses the industry average. This feature gives double glass modules a clear advantage in terms of long-term return on investment.
5. Environmental Adaptability
Double glass modules are particularly well-suited for environments with high humidity, high salinity, and high altitudes. They effectively resist external environmental influences, thus reducing maintenance and replacement costs. As a result, double glass modules are especially suitable for use in islands, at high altitudes, and in extreme climatic regions.
6. Effective Choice for Photovoltaic Systems
If you're looking for an efficient and stable photovoltaic solution with long-term return on investment, double glass modules are the ideal choice. By increasing light absorption and reflection at the rear, double glass modules can generate more energy from the same surface area, providing superior economic benefits for your photovoltaic system.
7. Development of the Double Glass Photovoltaic Module Market
With the continuous advancement of solar technology, double glass modules are increasingly becoming the preferred choice in the market. More and more solar system designers and engineers are opting for double glass modules to ensure the stability, long lifespan, and low maintenance costs of their photovoltaic systems. The growing trend of double glass modules is driving the entire photovoltaic industry towards a more efficient and environmentally friendly direction.
