You now see TOPCon solar panels becoming very popular. They are the next step after bifacial PERC. Solar energy keeps getting better as companies want better solar technology. TOPCon uses both sides to make energy and has new features. Many companies pick TOPCon because it can reach 23% efficiency. This is much higher than PERC modules. The special technology uses a tunnel oxide layer and passivated contact. This helps stop energy from being lost. By 2025, experts think TOPCon will have 45% of the market. This shows that many people in the industry support it.
TOPCon solar panels can reach 23% efficiency. This is 5.69% higher than bifacial PERC panels. You get more electricity from the same sunlight.
TOPCon panels last for 30 years. They lose power slower than other panels. They give steady power for a long time. This makes them a good choice for buyers.
TOPCon technology works with PERC production lines. Companies can upgrade easily and save money. They do not need big changes to their factories.
These panels work well in many conditions. They do well in high heat and low light. This makes them good for many places and weather types.
The market for TOPCon solar panels will grow a lot. This shows strong support from the industry. Prices may go down in the future.
You want your solar panels to work well. TOPCon solar panels are better than bifacial PERC panels for efficiency and performance. Tests show TOPCon panels make 5.69% more energy than bifacial PERC panels. TÜV Nord did a study in Malaysia. They found n-type TOPCon modules made more energy than p-type PERC modules in three months. This means you get more electricity from the same sunlight.
TOPCon technology works well in tough places. You will see good results in strong sunlight or high heat. TOPCon panels keep working even if the weather is not great. They do well in low light and high heat. If you live in a hot place like India, the Middle East, or Africa, TOPCon bifacial solar panels are more reliable. The low temperature coefficient helps TOPCon panels stay efficient when it gets hot.
You want your solar panels to last a long time. TOPCon solar panels last longer than bifacial PERC panels. Most companies give TOPCon panels a 30-year warranty. Bifacial PERC panels usually have a 25-year warranty. This extra time means your panels will work for many years.
Here is a quick look at the average lifespan:
| Panel Type | Average Lifespan (Years) |
|---|---|
| TOPCon | 30 |
| Bifacial PERC | 25 |
TOPCon panels lose power more slowly over time. In the first year, bifacial PERC panels lose about 2% of their power. TOPCon panels lose only 1.5%. After 25 years, TOPCon panels keep about 88.9% of their power. Bifacial PERC panels keep about 84.95%. This means TOPCon gives you more power for a longer time.
| Panel Type | Year 1 Degradation | 25-Year Capacity Remaining |
|---|---|---|
| Bifacial PERC | 2% | 84.95% |
| TOPCon | 1.5% | 88.9% |
You may see more companies using TOPCon technology. The solar industry thinks TOPCon will soon be the main choice for new projects. As more factories make TOPCon panels, the price will go down. This makes TOPCon cheaper for you and others.
Many big solar panel makers are changing from bifacial PERC to TOPCon. For example, LONGi made TOPCon technology better and reached a record cell conversion efficiency of 25.19%. This shows the industry trusts TOPCon for better results.
The market is moving toward TOPCon because it is more efficient, works better, and lasts longer. If you want the newest and most reliable panels, TOPCon solar panels are the best choice beyond regular bifacial solar panels.
You may ask why TOPCon technology is special. It uses a tunnel oxide passivated contact. This helps solar panels work better and last longer.
Here is a simple table that shows the main parts:
| Component | Description |
|---|---|
| Tunnel Oxide | A very thin layer, usually made of silicon oxide. |
| Doped Polycrystalline Silicon | This layer helps control electric charges. |
| Function | It lowers energy loss and helps move charges easily. |
Electrons move easily through this structure. The tunnel oxide layer acts like a gate. It lets electrons pass fast and keeps them from getting stuck. This means less energy is lost. You get more power from your solar panels. TOPCon technology can reach up to 25.7% efficiency. You get more electricity from the same sunlight.
TOPCon cells have advanced features. Here is a table that compares TOPCon cells to PERC cells:
| Feature | PERC Cells | TOPCon Cells |
|---|---|---|
| Technical Structure | Oxide film on the back | Thin tunnel oxide layer on the rear |
| Electron Collection | Good at collecting electrons | Even better at collecting electrons |
| Manufacturing Process | Simple process | Needs extra steps for the tunnel oxide layer |
| Efficiency Potential | Improved efficiency | Higher efficiency with better electron collection |
TOPCon technology works with PERC production lines. Companies only need a few new machines. This makes switching easy and saves money. You do not need to pay much more. TOPCon is cheaper than other advanced solar technologies like HJT. You get better performance without high costs.
Tip: If you want solar panels that give more power and last longer, TOPCon technology is a smart choice.
You want solar panels that make more electricity. TOPCon solar modules can make more power than before. Companies like LONGi and Trina Solar are leading this change.
