The TX unit can be powered by any 12V DC power supply. Power consumption is less than 100mA.
If you believe that powering the TX unit by solar energy is not feasible in your location, another possibility is to install the TX unit in the attic, and feed it from a 12V DC power supply. In this case, the cable to the anemometer should have no more than 5 meters.
I think a 10W solar panel, and a small 9 to 15Ah battery, is sufficient to ensure the functioning of the unit, even in a country like UK, but I can not guarantee.
