I got a few mixed responses, but basically I am trying to find out what is the formula to determine the correct solar panel, solar regulator and battery combination. Right now, I only know the the voltage of the regulator must equal the battery voltage. I am not sure about the wattage required for the panel and also for the required current for the regulator and battery.
For example, I was asking what was the combination for a circuit whose power supply was 5 V/1 A. I want to power this circuit for about 10-12 hours/day. The responses I got were:
Another question I have is that if my circuit needs 5V, would a 12V battery fry it or will it compensate?
For example, I was asking what was the combination for a circuit whose power supply was 5 V/1 A. I want to power this circuit for about 10-12 hours/day. The responses I got were:
- 15W panel (voltage not specified)/12V+5A controller/12V+10A battery
- 20W/12V panel/12V+5A controller/12V+10A battery
- 10W panel (voltage not specified)/12V+5A controller/12V+10A battery
- 5V+1A panel / 6V+2A controller/3.7V+4A battery (??? this one made the least sense to me)
Another question I have is that if my circuit needs 5V, would a 12V battery fry it or will it compensate?
