Understand the Technology

The best bifacial solar panels for efficiency and durability.

Bifacial Power Generation

Double- glass modules are able to absorb sunlight from two directions due to their double-sided design, thus increasing the efficiency of power generation. Under ideal conditions, double-glazed modules can generate 5% to 22% more power compared to single-glazed modules.

Reduced Hot Spot

With the use of multi-cut cells, the current is lowered, reducing localized overheating caused by current concentration. The glass backsheet has better heat dissipation performance, effectively reducing hot spots.

30- Year Warranty

Adopting glass backsheets with excellent waterproof performance effectively prevents water vapor from eroding the internal materials of the modules. This significantly reduces power loss and extends the service life of the module to about 30 years.

Certifications

SG-DG SERIES TESTING

Sungold SG-DG series bifacial solar panels are CE and RoHS certified, ensuring superior quality and safety. After a series of rigorous tests, including UV, humidity and heat resistance, thermal cycling and static mechanical load tests, they have demonstrated excellent reliability and durability under a variety of environmental conditions.

Bifacial Power Generation Technology

Bifacial solar panels can absorb sunlight from both sides. In addition to the 22.7% power generation efficiency, under ideal conditions, double-glazed modules offer a power generation gain of up to 22%.

Different installation environments can bring about different power generation gain effects, making it ideal for installations where the back side is exposed and can capture reflected light, including ground-mounted systems, solar carports and canopies.

Reduced hot spot formation

Sungold's double-glass modules have a significantly lower chance of hot spot effects compared to single-glass panels at the same power and voltage. Through the multi-slice process, the current in the cell is halved, reducing heat generation.

Meanwhile, the glass backsheet enhances the heat dissipation performance. This makes the hot spot effect in double glass modules half as likely or less than in single glass panels, ensuring greater safety and stability.

Adapting to Extreme Weather

Sungold bifacial solar panels are designed to withstand snow loads of 5,400Pa on the front side, ensuring that they can still function properly in areas with heavy snow accumulation. Meanwhile, the wind load of 2400Pa on the back side guarantees stability and safety in windy weather.

The application of IP68 protection rating enables the module to maintain reliability in hot, humid and dusty climatic conditions.

30 - Year Power Warranty

The glass backsheet significantly reduces power loss due to water vapor infiltration and reduces module life, extending its service life to approximately 30 years.

In addition, a 12-year material and workmanship warranty, a 30-year linear warranty, and a 30-year power warranty with a linear power degradation of only 0.45% ensure a long-term return on investment.

Explore More Application Possibilities

In addition to traditional installations, bifacial solar panels can be mounted vertically on fences, BIPV curtain walls and soundproof walls to increase energy yield.

 

The high durability of bifacial modules makes them ideal for sunrooms, agro-photovoltaic and fishery-photovoltaic projects, realizing efficient use of space and resources.

faq

What is the main advantage of the DG Series bifacial solar panels?
The DG Series features a dual-glass design that captures sunlight from both the front and back. Depending on the surface reflectivity, this can provide an additional power gain of 5% to 30%.
How does the dual-glass construction improve durability?
The dual-glass structure provides superior protection against PID, salt spray, and ammonia. It is exceptionally durable for coastal or high-humidity environments compared to traditional backsheet panels.
What type of installation is best for maximizing bifacial gain?
We recommend installing DG panels on highly reflective surfaces (like white roofs) and maintaining height above the ground to allow reflected light to reach the back side effectively.
What are the warranty and lifespan expectations for DG panels?
Sungold DG panels come with a 10-year workmanship warranty and a 25-year linear power output warranty, ensuring long-term reliability for your investment.
Does Sungold offer customized services for the DG series?
Yes, we provide full OEM/ODM services, including customized wattage, dimensions, and connection types for wholesale partners and large-scale projects.
