I'm a newbie in electronics, sometimes i do smaller projects, repair minor stuff. I would like to learn more about circuits, and calculating the structures needed. I study product design, so i'm interested in this stuff at every level. Any help appriciated.
We have a school project, we designed concrete covers for the bottom of traffic sign poles to protect them from cars running them over. The design features a lighting, powered by a solar panel and activated by a light sensor swich.
The questions i have: If i would like to power up 30 pcs of 3V 20 ma LED-s with a solar panel, and use a light sensor to activate and deactivate the lighting, what kind of/performance solar panel should i use, how big performance battery do I need to store the power, and what kind of light sensor do i need to complete the deal, finally: How do i put it together into a foolproof system, this will be cast into concrete.
I live in Europe, Hungary
Any help appriciated!
