Hi,
I don't have any "experience" with that sensor; the data sheet is easily available, but appears to give less detail than their UV sensor. You may get a few more "clues" from that (6490) data sheet/manual, which seems to use a similar enclosure.
The supply voltage is specified as 3.0 +/- 10% so ideally you should adhere to that (but a nominal 3.3 v is probably"safe"). The output signal voltage is also up to 3 volts (1.67 mV/W/m2), about 3 times larger than the Nano reference voltage so you probably need a resistor divider of about 1/3 (e.g. 2k + 1k, but the sensor output impedance doesn't appear to be specified). It's difficult to know if you should "modify" the standard Weatherduino Solar interface PCB, or build a simple, new "divider" interface directly between the 6450 and the "Transmitter" board.
The temperature sensitivity is specified as 0.12% per degree C, which may not be totally negligible. It would/could be corrected in the software, assuming that the temperature is "known" (probably not the normal "external" temperature because it's sitting in the sunshine).
Cheers, Alan.
