Haitai PV Panel HTM450 Topcon Bifacial EVO2 (Silver/White)
Couldn't load pickup availability
The Haitai Solar HTM 450 series is a solid choice if you're looking for a bifacial module for distribution or larger rooftop installations where additional yield, modern technology, and robust construction are important. For smaller residential rooftop installations, the added value may depend on the mounting conditions (space behind the modules, reflective substrate, shade) and the price.
-
The module is equipped with bifacial technology : this means that both the front and the back of the module can absorb sunlight, which can provide additional yield compared to standard monofacial panels.
-
Monocrystalline cells (high efficiency) with modern construction (glass-glass or glass/ceramic back panel) for better durability.
-
Suitable for use in demanding installations: high system voltage up to 1500 V, resistant to wind and snow loads.
Technical specifications
-
Nominal power: 450 Wp (front) for the HTM450 variant.
-
Voltage at Maximum Power (STC) (Vmp): approximately 29.72 V
-
Current at Maximum Power (STC) (Imp): approximately 15.15A.
-
Weight: approximately 24.5 kg for the 1762x1134×30 mm variant.
-
Dimensions: 1762x1134x30
-
Glass thickness: 2.0 mm high translucency glass, for both front and back in “glass-glass” or double-glazed construction.
-
Temperature coefficient Pmax: approximately -0.29 %/°C (i.e. at higher temperatures the power decreases by approximately 0.29% per degree).
Other
-
Increased yield : The bifacial construction allows for additional energy generation at the rear, depending on reflection from the substrate (such as light roofing, snow, etc.). For example, up to 5-30% additional yield can be achieved in suitable conditions.
-
Durability and robustness : The module is certified for severe conditions: snow loads, wind loads, corrosion by salt/ammonia, etc.
-
High system voltage : With a maximum system voltage of 1500 V, the module is suitable for installations with larger strings, which can reduce BOS costs.
-
Modern cell type & construction : Monocrystalline cells, half-cut or high-density layout, which improves efficiency and reliability (fewer micro-cracks, etc.) compared to similar series.
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.
