In addition to selective passivation contact technology, our products also adopt multi-busbar technology, which effectively reduces power loss. This means you not only enjoy efficient performance, but also energy savings. At the same time, the high reliability design of our products is also unique in the market. N-type components using Hot 2.0 technology have better reliability and lower LID/LETID. We are certified to withstand wind loads up to 2400 Pascal and snow loads up to 5400 Pascal. In addition, our products are also highly resistant to salt spray and ammonia gas, allowing them to flexibly respond to various application scenarios. It is worth mentioning that our products also feature ultra-low LID. The attenuation is only 1% in the first year and only 0.4% per year from the second to the 30th year. This provides end customers with long-term stable power generation income. At the same time, our PID-resistant cells and packaging materials also help reduce the effects of attenuation. All of this is a manifestation of Topcon's use of the power of technology to create more possibilities for you.
