High Conversion Efficiency: Topcon technology significantly increases the photoelectric conversion efficiency of the solar cell by adding a tunneling oxide layer and a polysilicon layer on the back side of the cell, which reduces the loss of electron complexes. Compared to traditional PERC (Passivated Emitter Rear Cell) cells, Topcon solar panels are more efficient and can utilise light energy more effectively.Luan 700W Topcon solar panel with a power generation efficiency of more than 20%.
Dual Side Power Generation Capability: Topcon solar panels can capture solar energy from both the front and back sides, with the back side taking advantage of light reflected from the ground (also known as the ‘Albedo Effect’) to further increase total power generation. For solar panels mounted on highly reflective surfaces, such as white roofs or snow, bifacial power generation offers higher efficiency.
Longer life: Topcon solar panels have a longer battery life due to the use of a tunnel oxide layer, a structure that dramatically reduces bandgap compounding, resulting in a lower attenuation rate, which extends the life of the battery and reduces long-term performance loss.
Excellent high-temperature performance: Topcon solar cells outperform traditional PERC solar cells in high-temperature environments, with lower temperature coefficients, which means that the efficiency drop is smaller under high-temperature conditions, and therefore still maintains a higher power generation efficiency under hot climatic conditions.
Good anti-PID performance: Topcon cells have good anti-Potential Induced Degradation (PID) performance, even in high humidity and high pressure environments, can maintain a stable output power, reducing the power loss caused by PID.

Solar panel efficiency is measured as the ratio of the electrical output generated by the panel to the amount of sunlight it receives. This is typically expressed as a percentage, with higher percentages indicating better performance.
Standard solar panels typically have an efficiency between 15% and 18%.
High-efficiency solar panels generally have an efficiency of 19% to 23% or higher.
High-efficiency panels generally perform better in lower light conditions (e.g., cloudy or early/late in the day) or in constrained spaces where maximizing energy output is critical.
Monocrystalline Silicon: Panels made from monocrystalline silicon are usually more efficient than those made from polycrystalline or thin-film. These panels typically have higher purity silicon and a more efficient manufacturing process, leading to better performance.
PERC (Passivated Emitter and Rear Cell) Technology: This technology increases the amount of sunlight captured by improving the cell’s rear surface, reducing electron loss, and enhancing efficiency.
Bifacial Panels: These panels capture sunlight on both the front and rear sides, potentially boosting overall energy production by capturing reflected light from the ground.
