When precision, flexibility, and scalability are paramount, not all Class AAA solar simulators are created equal. This side-by-side comparison of the G2V Sunbrick and ScienceTech SciSun-AM1.5G reveals key differences in spectral control, uniformity, automation, and beyond.
| Feature | G2V Sunbrick | ScienceTech SciSun-AM1.5G | Questions To Ask Yourself |
|---|---|---|---|
| Area of Illumination | 15 cm × 15 cm | 5 cm × 5 cm (Class AAA zone) | Will my sample size or test requirements grow as my research progresses? |
| Spectral Range | 350 nm – 1200 nm | 300 nm – 1100 nm (Xenon with AM1.5G filter) | Do I need coverage beyond 1100 nm or programmable profiles? Wil I need to filter out more of the spectrum for future research? |
| Spectral Control | 32 tunable LED channels | Fixed spectrum | Will I need to match non-standard or future testing profiles? |
| IEC 60904-9 Compliance | Class A+A+A+ (2020) | Class AAA (2007) | Am I publishing or certifying under the latest solar simulation standards? |
| Temporal Stability | <2% (over 100s of hours) | 0.13% (over 3.5 seconds) | Can I maintain test consistency over hours or days? |
| Spatial Uniformity | <1% | 1.4% | Do my samples need uniform illumination across every cm²? |
| Maintenance | No consumables | Requires periodic Xenon lamp replacement | How much downtime or recurring cost can I afford? What are the cost of bulb replacements? How many bulbs per year will I need? |
| Software & Automation | Full API (Python/REST), IV integration | Optional PC software (manual or TTL control) | Will I need to automate or run scripts across multiple instruments? |
| System Footprint | Modular, compact enough to fit on a desktop or lab bench | Free-space, optical rail layout | Does my setup require space efficiency? |
| Price per cm² | ~$56/cm² (225 cm² area) | ~$379.00 - $479.00/cm² (25 cm² area) | Am I paying more for less? What’s the real cost per usable test area? |
While both systems offer at least Class AAA performance, the G2V Sunbrick delivers significant tunability, automation, and certified area size advantages. With 32-channel spectral control and Class A+A+A+ compliance across the 15 × 15 cm area, it’s engineered for high-precision, evolving research needs.
While certified and well-built, the ScienceTech SciSun-AM1.5 G offers a fixed spectrum, a smaller test area, and a lamp-based design requiring periodic replacement and recalibration. It’s suited to basic workflows.
The G2V Sunbrick offers a more scalable and cost-effective path forward for labs prioritizing future-proofing, automation, and minimized downtime.
Top research labs, aerospace agencies, and photovoltaics innovators choose G2V because their work demands repeatability, compliance, and control. In fields where even a 2% deviation can invalidate results, “close enough” simply isn’t.
Whether you’re:
Validating next-gen solar cells
Investigating novel materials or light-dependent reactions
Automating precision photonic workflows
The G2V Sunbrick gives you engineered sunlight without the DIY workarounds, bulb swaps, or uncertainty.
