Class A+AA Solar Simulators

1. Product Overview

The Class A+AA Solar Simulators (Solaris Series) provide high-precision solar simulation for photovoltaic testing, research, and materials evaluation. Designed with a single Xenon Arc Lamp, these simulators meet IEC 60904-9:2020 Class A+AA standards, delivering 1 SUN output power without compromising on spectral quality, spatial uniformity, or temporal stability.

With five illumination area options, the Solaris Series enables testing of single solar cells, modules, or large-area devices, providing accurate and reproducible results in both laboratory and production environments.

2. Key Features

Class A+AA Performance

Certified Class A+ spectral match and Class AA spatial uniformity, with Class A temporal stability according to IEC 60904-9:2020.

Ensures high confidence in solar cell efficiency measurements with minimal measurement error.

Spectral Match – Class A+

Ideal spectral match across 6 wavelength ranges, deviation limited to 0.875–1.125× the ideal percentage.

AM 1.5G filter ensures long-term optical stability under continuous 1 SUN illumination.

Extended wavelength range: 300–1200 nm, covering the full solar spectrum (UV to IR).

Spatial Uniformity – Class AA

Irradiance uniformity ≤ 2% across the working area, minimizing hot spots and ensuring accurate PV cell binning.

Each unit is supplied with an irradiance non-uniformity plot for quality assurance.

Temporal Stability – Class A

Short-term instability ≤ 0.5%, ensuring accurate measurements during rapid fluctuations.

Continuous-wave (CW) operation allows all PV materials to be tested without flash-lamp limitations.

Xenon Arc Lamp – Continuous Wave (CW)

Ozone-free, single-lamp design certified for 1000 hours of spectral performance (extendable to 2000 hours).

Continuous illumination enables soaking cells at constant intensity prior to testing.

Replacement lamps and alignment palettes recommended for continuous production environments.

Power Supply & Monitoring

CE-compliant universal AC mains operation suitable worldwide.

Lamp usage hours tracked by the power supply to maintain 1 SUN output and spectral accuracy.

Spectral Coverage and Divergence

Reports include Spectral Coverage and Spectral Divergence per IEC 60904-9:2020 standards.

Verifies how well the simulator covers the full 300–1200 nm wavelength range and the deviation from the AM1.5G spectrum.

Adjustable Output

Variable attenuator enables 0.1–1.0 SUN output for versatile testing conditions.
