Full 2.4 frequency noise

Hi Community

I have resently scanned a sports facility on the 2.4 mhz band and found noise that I haven’t seen before. Is there any who have seen noise similar to his ?

There is solar panels on top of the building - but I dont know if they can producre this noise ?
The solar panel setup produces 60kw/h on a sunny day - so it is rather big.
But the noise does not increase when i go near the inverters.

Hope that you have an idea ?
I can upload or send a spectrum file if it helps.

Best regards

Could be lots of sources. Being sports facility, Microwave ovens leak badly, cordless phones, Blue tooth devices, video systems.
