And another one to supply 9V to the RF transmitter? Powered with just 5V its range is just a few meters.

This one will not be so simple. It would imply significant changes on the code and a lot of work investigating the output voltage for each wind direction for the FO anemometers. There are still other possible problems.
Isn't more easier increasing the power of the solar panel a just few watts more?
