The VSUN N-132BMH-DG series represents the latest generation of modules utilizing N-type TOPCon cell technology. Thanks to this architecture, the panels are characterized by almost zero light-induced degradation (LID), which translates into significantly higher efficiency over a long service life. A key differentiator is the Bifacial Dual Glass design, which, through the use of tempered glass on both sides, not only increases mechanical strength and resistance to extreme weather conditions but also allows for additional energy recovery from radiation reflected from the ground. This solution effectively eliminates the problem of micro-cracks and backsheet aging, which is a common issue with standard competitive products. These modules are an optimal choice for investors developing photovoltaic farms and large-scale commercial installations, where the priority is maximizing yields per square meter while simultaneously reducing the LCOE. This series performs excellently even at a low sun angle, offering a better temperature coefficient compared to traditional P-type cells. Choosing the VSUN N-132BMH-DG ensures Class A fire safety and energy stability that outclasses solutions based on older silicon technologies.

Common questions

6 answered
What is the N-type TOPCon technology used in the VSUN N-132BMH-DG series, and how does it differ from P-type?
TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell technology where an additional passivating oxide layer reduces carrier recombination. In practice this means higher efficiency (22.05-22.53%), near-zero LID degradation, and better performance at high temperatures compared to classic P-type PERC cells. Modules in this series reach up to 700 Wp with 132 cells, making them one of the higher-power constructions available for commercial-scale projects.
How much extra energy does the Bifacial Dual Glass construction of the VSUN N-132BMH-DG series generate?
Thanks to the double-sided design with tempered glass on both sides, the module captures light reflected from the ground surface. Depending on terrain albedo (e.g., light gravel, white roofing) and mounting height, this typically adds 5-15% extra annual energy yield compared to a monofacial panel of the same rated power. Dual glass also improves mechanical durability and eliminates the backsheet degradation risk common in cheaper single-sided panels.
What warranty does the manufacturer offer on the VSUN N-132BMH-DG series?
VSUN provides a 12-year product warranty and a 30-year linear power warranty, guaranteeing around 87.4% of initial output remains after 30 years of operation. This is a standard benchmark for modern N-type modules and stems directly from the low light-induced degradation characteristic of TOPCon technology.
How does the VSUN N-132BMH-DG series perform in high summer temperatures?
The series has a power temperature coefficient of -0.3%/°C, better (less negative) than the typical -0.35% to -0.40%/°C found in P-type cells. This means a smaller output drop on hot days and when modules heat up on a roof or ground-mount structure, resulting in higher energy production during summer months, especially in large-scale installations exposed to prolonged sunlight.
Are VSUN N-132BMH-DG panels suitable for mounting on a residential sloped roof?
This is not the ideal choice for a typical sloped roof. The module measures 2384x1303x35 mm and weighs around 38.5 kg, significantly more than standard residential panels, making rooftop handling and single-person installation difficult. The series is designed for solar farms and large commercial installations, where maximizing power output per square meter and lowering LCOE take priority over ease of installation on a small roof area.
Is VSUN a Tier 1 manufacturer, and where is the company based?
VSUN is not listed as a Tier 1 manufacturer under the BloombergNEF classification, meaning a shorter track record of bank-financed projects compared to top-tier players like Jinko or Trina. The company is headquartered in Germany, which simplifies warranty service and support for the European market. This is worth considering for large bank-financed commercial projects, though it does not affect the module's technical performance.
