[RFI] Anyone tested the Sunpower E-series 435 PV Panels?

[qrv at kd4e.com]

I had read somewhere that diodes in the panels could sometimes go bad 
and get leaky or something.


OK, so as long as RF doesn't get into the connecting wires the panels 
back to the controller should be clean.


The next step would then be to identify an RFI-quiet controller/battery 
bank manager, and inverter.


My south-facing shallow metal roof space is about 60 feel long and 24 
feet high, so I can arrange the

panels about any way I choose.


Thanks,


David KD4E
