A Solar Simulator For Wearables

Replicate the light conditions your products will encounter

Solar Simulation Trusted By These Companies

Test Your Wearables In Any Sun or Ambient Light Condition

Customers around the world will be wearing your technology and exposing it to different light conditions, both indoors and out. You need to ensure the viability of your wearable tech, from the highest to lowest intensities, in mW/cm2 or in lux.

Testing your product in every corner of the globe is not feasible, but with G2V LED technology you have access to every possible solar spectra and most ambient light to prove your wearables perform in every environment.

G2V solar simulators give you the flexibility to confidently scale your innovation out of the laboratory to the mass market.

Supercharge your research and development with flexible illumination.

Some of its features include:

Fully tunable intensity for every LED channel to produce AM1.5G, AM0, indoor lux values, and unlimited spectral creation
Python API and LabView DLL for automation
Large area output that’s scalable to fit your operation
World-class calibration services to ensure synchronicity across multiple site simulators

How Integrated Photovoltaics Are Powering Wearables

Battery life – in other words, available electrical energy—is a concern for any wearable technology. Thin-film solar cells are opening the door to solar charging rather than relying on traditional wall-plugs. You’re ready to incorporate photovoltaic technology, but need to know the most appropriate type. Is the solar cell that’s good for clothing the same as what you’d want in your fitness tracker? The details matter, and performance characteristics are essential in wearables.

Case Study: Wearable Tech Developer Needed Scalable Wide Spectrum

Problem: A multinational wearable technology company was developing a product they needed to rapidly test under a wide spectrum.

Innovation: G2V provided them with a 2×2 unit Sunbrick array covering the spectral range from 400 nm – 1500 nm.

Outcome: The wearable tech company was able to conduct initial testing to validate their devices, and scale up their operations and experiments with additional Sunbrick arrays.

G2V's FAQs

Do I have to reveal details about my proprietary technology in order to find the right solar simulator for my application?

No, we don’t need to know about your proprietary tech, and are willing to sign an NDA if needed. We’ll ask you a few questions about the dimensions (both area and volume) you’re trying to illuminate, as well as what your most important specifications are, but we’ll respect your confidentiality while still delivering an excellent solar simulator.

We are global and our team is spread out. Can you do multi-site support?

Yes, we can! We can calibrate multiple simulators in tandem to ensure synchronicity before shipment to multiple sites. Additionally, we provide ongoing support to monitor individual simulator output to ensure alignment in testing results across your organization, no matter the physical geography.

I want my device to work in low-light conditions. Can you produce accurate spectra at low levels?

Because G2V solar simulators were designed for maximum efficiency at 1-sun intensity, the drivers are not optimized for very low current outputs. However, low-flux solutions are still achievable in combination with neutral density filters. If this is a requirement, please get in touch with us to discuss how we can deliver the dynamic ranges you require for your research.

Can the solar simulator be used in combination with a test chamber?

Yes. In most cases if you can tell us the window material and thickness, we can calibrate your solar simulator to compensate for the glass transmission, so the irradiance your sample receives is the same high-accuracy spectrum we would normally produce without a window.
