How to Implement Current Limiting for TI Energy Harvesting Chip With Oversized Solar Panel

Hi,
First post here

I'm building an IOT device that needs to be solar powered.Due to existing conditions (northern hemisphere) I need to size my solar panel to worst case scenario making it over-sized in the summer months. I'm using a TI energy harvesting chip with 6V and around 500mA maximum spec. This will definitely be a problem during peak period so I guess I need to implement current limiting (that's what I'm guessing).

But I don't what to interfere with the energy harvesting part. Any pointers on where to start??

In Sicily (Italy) the Sun is very powerful and we have to limit more current.You can use bigger batteries.Or you can check the voltage on the batteries with a PIC with ADC. If the voltage of the battery is at upper limit, the PIC can unconnect the solar cell.Remember this as follow for a 12V batteries. For 6 Volt divide by 2:
- to measure the voltage of battery wait some minutes, without load;
- 12.6 V = 100%- 12.4 V = 75%- 12.2 V = 50%- 12.1 V = 25%- <12V = died
During the recharge, don't exceed 14.4V (good is between 13.8V and 14.4V).
