Traditional PV: The Cornerstone and Mainstay of the Solar Era

When we talk about solar power generation, the first image that comes to mind is often those neatly arranged dark blue or black panels on rooftops or vast lands. These are traditional PV, also known as crystalline silicon PV—absolute mainstays in today’s solar power sector. With their mature and reliable technology, they have laid a solid foundation for the global green energy transition.

What is Traditional PV?

The core of traditional PV lies in power generation using high-purity crystalline silicon. Its classic 'sandwich' structure comprises:

- Upper Layer: High-strength tempered glass for protecting solar cells.

- Middle Layer: The power generation core consisting of multiple silicon wafers—solar cells themselves.

- Lower Layer: Backsheet and aluminum frame, which deliver sealing, insulation, and structural support.

This structure endows it with sturdiness and stability, while also defining its rigid and relatively heavy physical form.

Core Advantages: Time-Tested Superior Quality

Traditional PV has dominated the market for decades, backed by three long-verified core advantages:

1. Mature Technology & High Reliability: After decades of development, the crystalline silicon technology route is highly mature with stable product performance. Boasting a service life of over 25 years typically, it is a 'reliable partner' validated by countless projects worldwide.

2. High Conversion Efficiency & Strong Power Generation Capacity: Both in laboratory settings and large-scale mass production, the conversion efficiency of crystalline silicon cells remains an industry benchmark—meaning it can generate more electricity under the same lighting conditions and area.

3. Distinct Cost Advantage & Prominent Scale Effect: Benefiting from a complete global industrial chain and fierce market competition, the manufacturing cost of traditional PV modules has dropped significantly. It has become one of the most economically competitive power generation methods, driving the large-scale popularization of solar energy.
