Scalable Class A+ LED solar simulators for CdTe, Perovskite, Tandem, and CIGS modules.
Speed is everything in solar panel manufacturing.
But thin-film technologies like CdTe, Perovskite, Tandem, and CIGS demand more than just raw throughput. They require precise spectral control, long-term stability, and the flexibility to adapt testing as modules evolve.
Whether it’s long-term reliability testing, from 8 hours to 30 days of cycling, degradation, and MPPT validation, or new product introduction with glass-glass bifacial modules, novel laminations, and next-gen architectures, manufacturers need testing that keeps pace without slowing the line.
From long-term reliability testing to new product development, offline validation is essential for thin-film PV. But when days of cycling and degradation studies meet tight production schedules, manufacturers face a critical question: how do you test fast enough, without sacrificing accuracy?
We’ve partnered with PV researchers and manufacturers worldwide, combining their insight with our proven Class AAA solar simulators to design the next generation of testing. With Suntile, we’ve advanced our systems to Class A+A+A+, delivering even greater precision for the unique demands of thin-film reliability and product development.
Built on the proven foundation of our Class A+A+A+ solar simulators, Suntile brings scalable, tunable LED testing to offline labs supporting solar panel manufacturing.
It’s designed not just for accuracy, but for outcomes that matter to manufacturers:
Lower cost of ownership — eliminate bulbs, filters, and frequent recalibrations
Long-term stability — steady-state operation for degradation, cycling, and power variation studies from 8 hours to 30 days and beyond
Quick recalibration — tighten performance back to spec whenever required, without extended downtime or complex procedures
Configured illumination area — sized at build (e.g., 2.4 m × 1.4 m) and maintained at Class A+; tiles are individually serviceable for fast swaps
Sustainable ROI — reduced maintenance overhead, extended lifetimes, and longer capital purchasing cycles
With expertise drawn from global PV leaders, we’ve created a solar simulator that balances the precision tomorrow’s thin-film cells demand with the reliability and control your product development and reliability testing require today.
The technicals matter. Your testing needs to meet production-level specifications and adapt as QC requirements evolve. Suntile delivers the precision and flexibility thin-film manufacturers demand:
Class A+A+A+ quality — compliant with IEC 60904-9:2020 standards
Broad spectral range — 350–1200 nm coverage for thin-film and tandem materials
32 tunable channels — independent spectral control for junction testing and light soaking
Extended lifetimes — warrantied to 10,000 hours, eliminating frequent lamp changes
Swappable tiles — fast replacement minimizes downtime and recalibration cycles
Configured illumination areas — proven performance at 2.4 m × 1.4 m; tiles are individually serviceable but field expansion requires new arrays
Python API integration — streamline automation, MPPT routines, and long-term test campaigns
Optimizing offline reliability labs and new product development has never been this straightforward.
Next is how Suntile performs in real-world testing, with measured results for spectral match, temporal stability, and spatial uniformity.
Engineers know the technicals matter. Suntile is built to not only meet but exceed the latest IEC 60904-9:2020 requirements for solar simulator performance. With Class A+ ratings in spectrum, spatial uniformity, and temporal stability, you get reliable, repeatable data that satisfies the strictest quality control.
Covering 350–1200 nm with 32 independently tunable channels, Suntile delivers unmatched flexibility for junction testing, long-duration light soaking, and validation of new thin-film materials. With warrantied lifetimes of 10,000 hours and swappable tiles, you stay compliant without costly downtime or frequent recalibration.
And beyond illumination, Suntile includes an integrated source measure unit (SMU), giving manufacturers a complete solution for both optical simulation and IV curve testing in a single system.
Suntile isn’t just a solar simulator; it’s a complete testing solution.
With an integrated SMU, you can illuminate your modules and capture accurate, high-resolution IV curves in the same system, eliminating the need for external instruments or complex setups.
Key Capabilities:
0.5% accuracy and precision across voltage and current ranges
Operating range: 40–350 V, 0.3–3.5 A
Fast IV sweeps: 1000 points captured within 300 ms
Comprehensive outputs: Voc, Isc, Jsc, Rsh, Rs, Vmax, Imax, Pmax, and Fill Factor (%)
With Suntile, optical simulation and IV characterization happen together, streamlining workflows in reliability testing and new product introduction.
Here are the most common questions we get from solar panel manufacturers about Suntile
Yes. Suntile is already proven in the field. Over 2,000 units are deployed today with world-leading solar panel manufacturers, running directly on their production line under real-world conditions.
Through this partnership, we’ve continually iterated both hardware and software to meet today’s production demands while preparing for the next generation of PV materials.
Yes. Suntile can test virtually every major solar cell technology. Our simulators are designed for flexibility, making them suitable for both current and emerging PV materials.
Technologies supported include:
Mainstream cells: crystalline silicon, amorphous silicon, multicrystalline
Next-generation PV: perovskite, tandem, multijunction, GaAs
Thin films: CdTe, CIGS, CuBi₂O₄, and other novel compounds
Organic and hybrid cells: DSSCs, OPV, inorganic solar cells, quantum dots
Yes. Stable operation from hours to months makes Suntile ideal for degradation, cycling, and MPPT validation.
Yes. An integrated SMU provides high-resolution IV curves and key parameters (Voc, Isc, FF, etc.) without external instruments.
Yes. “Easily swappable” means a failed tile can be replaced in minutes. Each Suntile is individually controlled with its own operating infrastructure, allowing you to disconnect and swap a tile without reworking the entire array.
For safety, we recommend shutting the system off before removal. Thanks to the low heat output of LEDs and their near-instant warm-up, most tile replacements take less than 10 minutes, keeping downtime to an absolute minimum.
Yes. Suntile stays cool with integrated water cooling. The closed-loop system maintains stable operation, keeping temperature variation across the entire simulator to less than 3 °C.
This ensures consistent performance, protects components, and eliminates the overheating issues common in lamp-based systems.
No. Arrays are factory-configured to size; tiles are swappable for service, but expansion requires a new, configured array.
Yes. Suntile exceeds IEC 60904-9:2020 Class A+ requirements.
Optimizing solar production isn’t just technical; it’s about throughput, uptime, and cost efficiency. We’re here to help you on the journey.
