"I want to power a module that requires 3.3V and 500mA minimum for startup. I have a solar panel that outputs max 3V at 70mA and a 3.3V 3A max output boost converter. I know I need a super capacitor or a capacitor bank to store energy so I can get the current needed for start up. Also, my module only needs around 500mA for less than 1 second. I will probably consume an average of 10-40mAh.
I do not know too much about power electronics, but I want to know how can I design a capacitor power bank circuit that can handle 3.3V, can store a minnimum of 500mA, only takes less than 5 minutes (if possible) to charge the capacitor bank to 500mA, discharge the current for 30ms or more and have the capacitor discharge when full.
This 500mA current is only required once per day or when the solar panel drops below 1V.
I only want my device to be on during the day."
Above was my previous question. Below is my new information!
- My size requirement is a 2x2 solar panel
- Cannot have a battery, customer wants power only during day or peak hours
- The figure is what I have been calculating on the wattage required
Will this work?
- I have purchased the evaluation board for the boost converter and set a breadboard circuit up with smaller capacitors and supplied voltage to a red led, but it doesn't have consistent power, it blinks fast like a relay.
Also, when i supply this power to my wifi module, will this provide consistent power throughout the day after the startup requirement?
