Solar simulators are core equipment in photovoltaic testing, used to simulate sunlight indoors and provide key data for the performance evaluation of cells and modules, directly impacting product quality and market pricing.

Early PV testing lacked unified standards, leading to discrepancies in power ratings and trade disputes. The IEC 60904 series requires that all measurements be conducted under Standard Test Conditions (STC), including 1000 W/m² irradiance (AM 1.5G spectrum) and 25°C cell temperature. Solar simulators ensure global consistency and fairness in testing.

We provide calibration services in compliance with IEC 60904-9:2020, covering the 300–1200 nm wavelength range. Key calibrated parameters include:

• Spectral match
• Irradiance uniformity
• Temporal stability
•  

GRGTEST ensures your equipment continues to meet international standards, with data recognized worldwide.

Flash Solar Simulators: Used in mass production sorting and power testing; measure I-V curves and key parameters (Pmax, Isc, Voc, FF, Eff). Calibration accuracy directly affects product grading.

Steady-State Solar Simulators: Used in R&D and quality validation (e.g., light soaking, hotspot tests); evaluate performance and durability through stable irradiation. Calibration supports process improvement.

• International recognition: Compliance with IEC standards ensures global data validity.
• Industry coverage: Services for PV and automotive sectors (e.g., environmental light testing, material aging tests).
• Geographical reach: Services cover China and Southeast Asian countries (Vietnam, Cambodia, Thailand, Laos), providing local technical support.

Regular calibration prevents power rating errors, reducing economic loss and brand risk. It is essential for ensuring product quality and fair trade.
