Monocrystalline silicon PERC (Passivated Emitter Rear Contact) module is a kind of solar cell module, which is made of monocrystalline silicon material and applied PERC technology. PERC technology is to improve the photoelectric conversion efficiency and performance of the solar cell by adding a reflective layer and additional metal electrodes on the back of the solar cell. Specifically, the PERC module introduces an additional metal electrode on the back of the cell, allowing solar light to travel longer in the solar cell, increasing light absorption and opportunities to generate current, thereby improving photoelectric conversion efficiency. Therefore, monocrystalline silicon PERC modules are currently one of the most common and widely used high-efficiency solar cell modules in the solar field. It can be used in various types of solar power systems, including rooftop installations, commercial applications, and large-scale solar power plants.Higher photoelectric conversion efficiency: PERC technology makes the photoelectric conversion efficiency of monocrystalline silicon PERC modules higher, usually reaching more than 20%. Better low-light performance: Monocrystalline silicon PERC modules perform better in low-light conditions and can generate higher power output. Higher reliability and lifespan: Monocrystalline silicon PERC modules are made of high-quality monocrystalline silicon materials, which have high reliability and long-term stable performance.Q1: How could I buy the solar panel if there is no price in the website?
