Traditional photocatalytic research uses "lamps" as the light source for reactions, simulating sunlight with lamps. The PLS-STAS-I small-scale solar double-axis tracking application system can directly utilize sunlight to drive catalytic reactions in outdoor environments. It is an application-based testing platform for researching solar energy utilization.


Achieved high-precision solar tracking and focusing:

Conventional products typically use photoelectric tracking, which is highly accurate but may have difficulty responding to changes in light when it's cloudy or when sunlight is weak (while scattering is relatively strong). This can lead to misalignment or even serious accidents. Perfectlight Technology's independently developed solar tracking system employs both photoelectric tracking (light control) and solar position tracking (time control) to achieve higher accuracy and safety.
