This is a solar panel from Trina Solar from the “Vertex” series , model TSM-DEG19C.20 a monocrystalline, bifacial (double-glass) module. "Bifacial double glazing" means the panel can utilize light from both the front and the back, which can provide additional energy, especially on reflective surfaces. The panel uses 210mm PERC solar cells.
Overview & key data
This is a solar panel from Trina Solar, from the “Vertex” series.
Rated Peak Power: 550Wp (with power tolerance 0 ~ +5W ) — which means the panel will output at least 550W under STC.
Module efficiency: up to 21.0% under standard test conditions.

Performance, reliability & practical benefits
Thanks to its high peak power (550 Wp) and relatively high efficiency, this panel is particularly suitable for situations where you want to generate a lot of power per panel — for example on roofs with limited roof surface area, or when you want to minimize the number of panels.
The use of monocrystalline PERC cells and high-density interconnect/multi-busbar technology contributes to efficient power generation, better light capture, lower losses and reliability.
The double-glazed (glass-glass) construction increases durability and makes the panel robust — resistant to shock, wind/snow loads, and environmental factors (temperature, moisture, corrosion).
The low temperature coefficient means that performance remains relatively stable at higher outdoor temperatures (limiting yield loss in hot weather).
The integrated EMS automatically optimizes consumption, storage, and grid load. In the event of a power outage, the system switches to backup power within ≤10 ms.
With a built-in EMS (Energy Management System), support for peak shaving, and flexible charge and discharge settings, energy balance is automatically adjusted to consumption, grid status, and storage.
With an IP66 enclosure, silent passive cooling, and real-time monitoring via app or WiFi, the inverter offers reliability, ease of use, and minimal maintenance requirements.
- Businesses may need to employ various types of legal pages on their websites or mobile apps. Some, like Privacy Policies, are required by law, while others, such as a Terms and Conditions agreement (T&C), are not. Regardless of legal demands, you may find that your company needs one or more legal pages for compliance and optimal operation.
- In this article, we will go over the most common legal pages, walk you through a summary of what each requires, and explain why you may need it. In addition, you'll find a sample template for each type of legal page so you can quickly get started writing your own.
