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.
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.
Frequently Asked Questions
A bifacial solar panel is capable of capturing sunlight from both sides, generating electricity. Unlike traditional panels that absorb light from only one side, bifacial panels can enhance energy output by utilizing reflective surfaces around them, such as rooftops, the ground, or snow.
Bifacial solar panels, with their ability to harness light from two sides, can offer higher energy outputs, especially in environments with large reflective areas, making them a potentially worthwhile investment. However, their higher initial costs should be weighed against the long-term energy savings to assess their overall value
In optimal conditions, bifacial solar panels can outperform monofacial panels in efficiency and energy output, particularly in open and reflective environments. However, whether to choose bifacial or monofacial panels should depend on specific project needs and budget considerations.
Bifacial panels generally surpass monocrystalline panels in efficiency and potential energy output, especially in favorable installation environments. However, the higher cost may impact their cost-effectiveness.
Higher cost: Bifacial panels require a greater initial investment compared to monofacial panels.
Complex installation: The performance of bifacial panels heavily depends on their installation, requiring precise considerations of height, tilt, and ground reflectivity.
Roof space limitations: Bifacial panels may not offer an advantage over monofacial panels in limited roof spaces.
Weight issues: Some bifacial panels may be heavier or more fragile due to glass on both sides.
Bifacial solar panels can be installed on the roof, but they perform better in ground-mounted systems where they can capture more reflected sunlight. On roofs, the additional energy gained from the back side may be limited due to low reflectivity. However, with appropriate roof configurations, such as implementing special measures to enhance reflectivity, bifacial panels can still be a good choice.
