Using a solar panel as a dusk til dawn sensor? Answered
Someone on my youtube channel commented that you could use a solar panel as a dusk till dawn sensor. Let me explain the scenario. I used a solar panel to keep a battery topped up, which was wired with a digital timer switch to operate an automatic car antenna. At a certain time of the day, it would extend, and then at night, it would retract, according to the timer I programmed.
So enter this person's comment:
Can I just say, you don't even need the timer. Use the load outputs from the charge controller and the door will open as soon as sun hits the solar panel and close again at sunset.. The charge controller has the timer function already built in.
Now he is obviously referencing a charge controller, which is NOT part of my set up. The solar panel I use has built in overcharge protection, so no need for a charge controller.
Can someone tell me what he's referring to, or how to wire it? Would I need a different solar panel? Because the one I use doesn't play well with a charge controller. If I attach the solar panel to it, it doesn't charge the battery.
Thank you to anybody that can help.
