* solar panel is the major power source, and it will be the only power supplier as long as its output is sufficient to run the fan

* AC/DC power adapter is the backup power source, and it will be consumed only when sunlight is not available

there is the chance that solar panel is working together with AC/DC power adapter to supply power to the fan, however, solar panel is still of priority, and AC/DC power adapter is still as backup only

24 hours nonstop cooperating in a best way for you

if solar panel is supplying direct power at X%

AC/DC power adapter will be at (100-X)%

* there is an inbuilt controller inside the junction box to take care of the power supplies between solar panel & AC/DC power adapter
