Help with solar circuit Answered

Hello again instructables community. I have yet another question. So i want to make a led sign and i want it to be on all day long. So i have bought a battery and a solar panel and i want the solar panel to light it in the day AND charge the battery if it has enough sunlight ( here it will have more than enough sunlight about 6 hours per day because it is a big panel). When not enough sunlight i want it to only light the leds and at night i want the battery to light them. So problem is how can i make it so that the solar will light the led and charge the battery but when it can't do both it will only light the leds?

Thank you for your reply. So would it be easier to just connect the solar to the battery and then make the led array be powered by the battery which will be connceted to the solar panel so it wont run low on energy fast? I dont want to overcomplicate things yet and i think this would work well!

The cirucuit you will need will have to measure the amount of electricity being created by the charging uinit, with a heuristic switch which will shut if off if it gets too low. With the power consumption required for this along with the just mentioned cirucuit, you are looking at a bit of complexity if it can be done.
