690W-710W solar panel usage
690W-710W solar panels are used in large-scale projects and power-intensive areas that require efficient power generation, due to their advanced technology, high power generation efficiency and better utilization of mounting space
Demand for large-scale commercial projects and power plants: 690W high-power panels are mainly used in large-scale photovoltaic power plants and commercial projects. As the global demand for clean energy increases, especially in China, India, Europe and North America, the demand for high power solar panels is growing rapidly.
Improved system efficiency: Compared to traditional lower power solar panels, 690W-710W solar panels can significantly improve power generation efficiency, thereby reducing installation costs, land use, and power transmission losses.
Technological advancement in the PV industry: With the application of advanced technologies such as PERC (passivated emitter and back-side cell), HJT (heterojunction technology), TOPCON, etc., high power panels of 690W and above have become high-efficiency solar solutions.

What are the advantages of TOPCon technology?
The main advantages of TOPCon solar cells are their high efficiency and lower degradation rate. It reduces the recombination loss of carriers through the tunneling oxide passivation contact (TOPCon) structure, so it can significantly improve efficiency and achieve a conversion efficiency of more than 25%. This design is more stable in the face of high temperatures and different environmental conditions, and is especially suitable for applications with high energy requirements.
How much does a TOPCon battery cost?
Although the initial manufacturing cost of TOPCon batteries is higher, it can provide a higher return on investment in the long term due to its higher efficiency and longer service life. Its advanced technology and materials require more process steps, resulting in higher costs, but the higher power generation efficiency and lower decay rate make up for this
How does TOPCon technology compare to other battery technologies?
Compared with traditional PERC cells, TOPCon cells have higher efficiency and lower light attenuation, especially under high temperature conditions, and are more stable. Compared with HJT (heterojunction) cells, TOPCon’s production process and cost are closer to the existing PERC process, making its conversion to industrial-scale production more feasible
What is the future development trend of TOPCon batteries?
TOPCon technology is still developing and is expected to continue to break through efficiency bottlenecks. With further optimization of the manufacturing process, the cost of TOPCon batteries is expected to further decrease, while its efficiency may exceed 26%. Advances in this technology make it an important part of the future solar market.
