I am looking for an optimized power supply set up with solar panel and battery for field measurement with the Rasberry Shake Boom model.
If I consider that the set up require a 5V DC 2.5 Amp power supply, than I need a daily supply of 306 watt-hour. Consequently, I need a 85 amps-hours at 12 volts battery and a 101 watts solar panel.
This agrees with the set up presented in this link: Solar Power Recommendations — Instructions on Setting Up Your Raspberry Shake
But I want to optimize the set-up with smaller battery and solar panel.
In the manual, it is mentioned the following power supply characteristics:
Startup: 5 Volts x 0.550 A = 3.1 Watts
Run-time: 5 Volts x 0.290 A = 1.9 Watts
In this case, I would need 74.40 watt-hours/days corresponding to a battery of 21 amph at 12 volts and a solar panel of 25 watts.
Anyone has feedbacks on solar panel/battery set up?
Thanks in Advance,
