Solar panel monitoring system

hello everyone ,
i’m using openhab with raspberry pi and esp8266 wifi module to make a solar panel monirtoring system . its a part of my masters-degree work .
i need suggestions for other options that can be added to my system for Maximizing benefit from the tools i’m using in such a project and make the system have Multiple functions .

Well, I thought a masters has a “scope” and requires a significant “research” component; why not start here:

Maybe have car chagrining api on the 8266 so you can tell the car when it can charge
