I am disappointed that no labs have responded! We have a very bright halogen lamp which we will use. Hopefully we don't melt the plastic!!
Thanks!

But the test is not about the detailed performance of the solar panel, but only that the device-under-test runs off electricity generated by the solar panel. Unless the EMI signature somehow depends on the type of light impinging on the panels, as opposed to a nominal electric output from the panels, it would seem that any electrically quiet light source would suffice.

The spectrum (or energy) for artificial light will not be the same as the spectrum of sunlight. UL 1703 makes reference to a few different standards, including ASTM E927 <https://www.astm.org/Standards/E927.htm> , which describes performance requirements for a solar simulator <https://en.wikipedia.org/wiki/Solar_simulator> . IEC 60904-9 <https://webstore.iec.ch/publication/3880> does the same. Here <http://www.eternalsun.com/industries/certification/><http://www.eternalsun.com/industries/certification/> is an example of a solar simulator manufacturer claiming that their product is appropriate for PV cert testing, including for IEC 61215 <https://webstore.iec.ch/preview/info_iec61215-1%7Bed1.0%7Db.pdf> . This is very likely overkill for what you need to do, but you should be aware of the limitations of using a common incandescent. IEC 62920:2017 covers PCE (power conversion equipment, i.e. the inverter), but not the modules themselves so I don't believe it has guidance on an artificial light source.

The solar panel is integrated with the electronics. Does anyone have any ideas on how to have the panel function when testing in a chamber? I am looking at you test labs!! Thanks!
