N-Type TOPCon Solar Panels
TOPCon (Tunnel Oxide Passivated Contact) solar panels are advanced N-type modules designed to improve efficiency, reduce energy loss, and increase long-term power generation performance.
Compared with traditional PERC technology, TOPCon solar panels offer higher efficiency, lower degradation rates, and better performance under high temperature and low light conditions.
HBOWA offers you Tier 1 TOPCon solar panels from leading manufacturers, including Jinko, Trina, Canadian Solar, Astronergy, Tongwei, and Risen for utility-scale and commercial solar projects. Whether you are a solar panel installer, distributor, retailer, or solar power system solution provider, HBOWA can be your stable and reliable choice in the solar panel supply chain.
HBOWA supply you with high quality topcon solar panels of various powers, suitable for residential, commercial, and industrial applications.

HBOWA N-Type TOPCon Solar Panel
We will conduct a 100% EL test of each panel to check if there is any problem during processing.
The TOPCon Solar Panel is a clean and renewable source of components and generates no greenhouse gas emissions.
HBOWA is a solar panel manufacturer, directly buying from our factory, you can get the factory price of solar panels.
Our TOPCon solar panels are suitable for household energy backup, commercial and industrial energy systems, and so on.
What is TOPCon Solar Panel?
TOPCon solar panel technology is based on N-type silicon cells with a tunnel oxide passivated contact structure, which significantly reduces electron recombination and improves energy conversion efficiency.
TOPCon vs PERC Solar Panels
| Feature | TOPCon | PERC |
|---|---|---|
| Efficiency | 22–23.5% | 20–21% |
| Degradation | Low | Higher |
| Temperature Performance | Better | Average |
| Technology Type | N-Type | P-Type |
| Market Trend | Replacing PERC | Phase-out |
TOPCon Solar Panel Efficiency
Most TOPCon solar panels on the market, which are under mass production, achieve module efficiencies between 22% and 23.5%, while advanced laboratory and next-generation designs can reach up to 24%–25% under optimized conditions. The efficiency of TOPCon solar panels depends on cell structure and the manufacturer’s technology.

FAQ
High-power solar panels use TOPCon technology, including 550W-600W, 600W-650W, 650W-700W, 700W-720W+. And 700W-720W TOPCon solar panels are the most common high efficiency utility-scale products.
TOPCon solar panels are mainly produced by leading Tier 1 solar manufacturers, such as Jinko Solar, Trina Solar, Canadian Solar, JA Solar, LONGi Solar, Risen Energy, Astronergy, Tongwei Solar, etc. These manufacturers represent the mainstream global supply of TOPCon solar panels.
HBOWA have reached 22.84% high-efficiency conversion for 182mm TOPCon solar panels, and 23.18% conversion efficiency for 210mm TOPCon solar panels, and we will continue to develop our technology to reach higher efficiency to adapt to the market needs.
TOPCon solar panels are known for higher efficiency compared to PERC panels, and are more expensive than PERC solar modules.
Both HJT and TOPCon are advanced technologies to improve the power conversion efficiency compared to traditional solar panels. They are different in structure and manufacturing. The choice between them may depend on specific application needs.
Yes, sure. We support your business by providing standard and OEM/ODM solar products. If you have any special requirements, feel free to tell us, we are always here at your service.
The output power of photovoltaic panels will decrease as the temperature rises. The most commonly used method is to use natural wind for ventilation to improve power generation efficiency.
