The Sunova Tangra L Pro HD solar panel series represents a breakthrough in energy yield optimization through the use of advanced N-type TOPCon cell technology. The use of this solution allows for the near-complete elimination of the LID degradation phenomenon, which, combined with excellent PID resistance, guarantees stable power for decades. These modules are characterized by a high bifaciality factor, meaning they can generate additional energy from reflected radiation, which is key to increasing the profitability of ground-mounted farms and large commercial roofs. The Bifacial Double Glass construction not only reinforces the mechanical structure of the panel but also provides extreme resistance to harsh weather conditions, including high humidity and snow loads. The Tangra L Pro HD series addresses the issue of performance drops at high temperatures through an exceptionally low temperature coefficient, distinguishing it from standard market solutions. Thanks to the use of precision Half-Cut cell technology, these panels perform excellently in partial shading conditions, minimizing internal losses. It is a product dedicated to demanding business investors and developers who care about the lowest Levelized Cost of Energy (LCOE) and maximum reliability of PV systems.

Common questions

6 answered
What is the maximum power output of the Sunova Tangra L Pro HD panels?
The Tangra L Pro HD series reaches a maximum power output of up to 720 Wp. This high output is achieved through N-type TOPCon cell technology combined with precise Half-Cut cell cutting, which minimizes internal losses. A higher power rating per module means fewer panels are needed to reach a target system size, reducing mounting structure and installation labor costs.
What warranty comes with the Sunova Tangra L Pro HD panels?
The manufacturer provides a 15-year product warranty and a 30-year linear power output warranty. This means that even after three decades of operation, the panel is expected to retain a significant share of its original rated power. This level of coverage is typical for modern N-type modules and reflects the manufacturer's confidence in the durability of the cell technology used.
What is bifaciality, and do the Tangra L Pro HD panels have it?
Yes, the Tangra L Pro HD modules are bifacial, meaning they generate electricity from both the front and rear side of the panel by capturing reflected light from the surrounding surface. Thanks to the Bifacial Double Glass construction, the additional energy yield can range from a few to over ten percent, especially in ground-mounted installations over bright or reflective surfaces such as gravel or white roofing membrane.
Are the Sunova Tangra L Pro HD panels suitable for solar farms and large commercial roofs?
Yes, this series is designed for large ground-mount installations and commercial flat roofs where minimizing the levelized cost of energy (LCOE) is a priority. The high per-module power output, bifacial design, and robust Bifacial Double Glass construction resistant to humidity and snow loads make it a strong choice for investors seeking maximum reliability at utility scale.
Does N-type TOPCon technology in the Tangra L Pro HD reduce power degradation?
Yes, the N-type TOPCon cells virtually eliminate light-induced degradation (LID), the power loss that typically occurs during a panel's first hours of operation. The technology also offers excellent PID resistance, allowing the module to maintain stable performance over many years, which translates into higher real-world energy yield compared to conventional P-type panels.
Do the Sunova Tangra L Pro HD panels perform well in high temperatures?
Yes, the Tangra L Pro HD series features an exceptionally low temperature coefficient, resulting in smaller power losses on hot days compared to standard market modules. This is a key advantage in high-irradiance regions with elevated ambient temperatures, where modules regularly operate well above the STC reference test temperature.
