Reliable Validation of Solar Panel Manufacturing Performance

Whether you are manufacturing solar panels for homeowners or businesses around the world,  you’re a leader in the renewable energy movement and people are counting on you to deliver.

When it comes to delivering a top product on time unexpected maintenance delays cost time, money, and potential partnership

But what if you could reduce the risk of solar simulator line maintenance?

Switching from traditional xenon solar simulators to LED might just be what your lines need.

With G2V Optics Class AAA solar simulator you are no longer left in production limbo waiting on bulb replacements, excessive warm-up times, or field calibration just to get back on schedule.

With >10,000 on the LEDs, minimal warm-up times, no field calibrations, and no risk of bulb dimming you can better plan your maintenance times.

Are you ready to improve your production uptime and give your QC department Class AAA light?

Sunbrick™ Solar Simulator for Solar Panel Manufacturers

Your solutions are as big as your ideas. Whether your manufacturing expertise is in thin-film for mobile power, building-integrated photovoltaic (BIPV) module, or silicon solar panels, our G2V Sunbrick will allow you to illuminate and test all of it. Improve your line's QC with reliable and accurate sunlight.

Engineered Sunlight for your solar panel manufacturing lines.

How the Sunbrick Helped Rayleigh Solar Tech Commercialize Perovskites

Problem: Dr. Sam March, co-founder of Rayleigh Solar Tech, had demonstrated his perovskite technology in the lab at a 1” x 1” scale, but he needed a reliable larger-area solution to reach commercialization.

Innovation: G2V’s Sunbrick provided the large area, reliable solar simulation that Dr. March needed.

Outcome: The G2V Sunbrick was integrated into a testing chamber design that has enabled Rayleigh to accelerate its testing to push perovskites to commercial viability.

Frequently Asked Questions (FAQs)

G2V doesn’t currently provide automated testing solutions out of the box. However, there is a Python API (included with the Sunbrick and the Pico’s Variable Module) and a LabView DLL (Sunbrick only) so customers can implement a scripted automated solution that fits their needs. We’re always happy to work collaboratively to ensure the fit is right. Furthermore, we’re always building out and planning our future product roadmap; any feature suggestions you have are welcome!

All of our solar simulators are currently calibrated using several detectors calibrated by a third-party lab, which qualify as “gold” cells, all of which are metrologically traceable to NIST. This is done to reduce the reliance on a single source and achieve a calibration closer to the world average. In the future, we may introduce some comparisons against “silver” cells, but that information will be communicated transparently in the metrology section of our extensive QC reports.

Reported LED lifetimes range from 10,000 to 100,000 hours depending on manufacturer and conditions. Most reported lifetimes are for LEDs driven at maximum current. We design our solar simulators to drive LEDs at lower currents, which results in the LEDs performing closer to the maximum of their lifetime range. Our solar simulators are rated for 10,000 hours and covered by a full two-year warranty.

The EQE module (only available with our Pico product) uses individual LEDs to probe a device’s spectral responsivity, and as such, the resolution of the resulting EQE curve is limited to the wavelengths of the LED types used in the solar simulator. While you won’t achieve nanometer resolution from our EQE module, you will get a low-resolution snapshot (between 25 nm to 100 nm on average) that still contains valuable device information.

The IV module is currently only available with the small area solar simulator, the Pico, but an IV module solution for the Sunbrick is currently on G2V’s product development roadmap. In the meantime, we recommend pairing Sunbricks with a source meter such as a Keithley 2400 series and a custom characterization system with Sinton Instruments. Contact us for extra information.

Our solar simulators will illuminate their specified areas with Class A spatial non-uniformity (Sunbrick providing large area, Pico for small areas), so the number of busbars is ultimately limited by the size of the individual solar cells you’ve connected on a busbar. If you are concerned about micro-features in the illumination field, get in touch and we can discuss the resolution of our validation measurements and whether a higher-resolution spatial measurement may mitigate your concerns.
