Kim, I am in the same type of situation about Commercial Solar Farms in LaGrange Indiana. The county commissioners passed a ordinance allowing agricultural property to be transformed into solar farms. This type of change can cause alot of problems for amateur radio operators.

Any type of information that can be shared will be useful! Thank-you Scott K9MA for sharing.

Respectfully,
Jim N9PXO

Hopefully not as bad as the 2.3 MS Siemens wind turbines in New Zealand. ZL6QH 
had to abandon a huge antenna farm because of RFI. Their noise floor went up 50 
dB on 80, and only a few of the planned turbines were in operation. While not 
quite the same, solar and wind power systems both use high frequency switching 
converters capable of generating lots of RFI.

I just learned that a 2 MW solar farm is being built about 3/4 mi from my QTH. I don’t 
know who is behind it, though I ssume it’s a utility company of some sort as 2 MW 
sounds moderately large. Does anyone have any experience with these? How much of an RFI 
source are they?
