The entire system at rest is 9.68mA and 39.9mA with one timer on.
That's some good information. So based on that you know the system uses about 250mAh in 24 hours plus how much energy it takes to open and close the door. A person just needs to know how much sun they get and size the solar panel and battery to suit their location.
For me when it get complicated like the through beam and dual timers I prefer to use a Raspberry Pi 3 B or 4 B with a 4 relay board as it makes for a much more compact setup. The drawback is you have to program that in Python. The advantage is it updates the sun events each morning so you don't have to change timers.

It is not really all that complicated. Two timers are the same amount of wiring compared to one timer and a DPDT relay. Yet the two timers is way less complicated.
