Hi, I am working with cube cell development board to collect data from remote place where power is not available. I have to use solar panel with reasonable battery capacity. I am thinking of using 2600 mAh lithium ion battery with 10 w solar panel. I need to know the charging current of the onboard battery charger to find out the duration for charging the battery. I couldn’t find this information in the technical specification. This place is away from my present location so I cant go frequently if the module not working properly.
I need to collect the data for every minute and sensor consumes approximately 100 mA for every reading. The entire system should run for 15 days without sun shine (considering worst monsoon season). The place where I am going to install the sensor is getting average sun shine except monsoon season.
I am also thinking of LoRa kit from heltech instead of cube cell series which is newly released and having some issues.
suggest me the suitable battery capacity, rating of solar panel and others if any
Thanks in advance
