Ok let me explain even though you want the system to run 24/7 you still need to come up with a run time for the batteries so you can size them properly. Meaning without sun how long do you want the system to run for....... example 24 hours or 72 hours. Once you have your run time needs you now can size the solar panels for your needs. Remember to have enough wattage to charge the batteries and run your equipment when the sun it out.
Also I would spec the equipment to run on 12VDC or 24VDC to have the most efficient setup.
Thanks for sharing such useful information..I am trying to get similar system and i will surely keep these points in mind.
