I build a system of 2 solar panels. 18 times 0.5 Watt per panel is 9 volt. I want to make 18 V system so it can handle the 12 V battery I am looking to buy.
Is this correct> or is it better to buy 6 V battery?
I have to buy the diodes for this system.
I look to use my supercheap charger controller 20 amp,
All the system needs to do is keep flooding the front garden with a light of some sort. I need to buy this thingy that detects light, but I forgot the name. I put this before the lights. Is that enough or should I use a diode too?
