I am on a net metering program where the rates are tiered, so the rates for electricity goes up as my consumption increase in 2 tier system. Electricity consumption and produced are metered separately, so given my production is less then consumption, it is best for me to actually net out my consumption and production as much as possible to minimize net consumption to minimum paying the higher tier 2 rates.
The largest electricity consumer that I can easily control is car charging. So instead of charging at night where I would consump from the grid, I would want to charge during the day to draw from the panels instead. I have a 15kWp system connected to a 10kW SolarEdge inverter. Peak production of 10kW usually occurs around 10am-3pm range, though the output is a lot lower when it is cloudy.

- Get an energy monitor with API access to observe the net production, use Tesla API to very the charge current to "use that up"
- API access between SolarEdge inverter and Tesla to charge during the day time and vary the charge current based on solar output. Reserving 2kW for base load of home.
- Manual schedule to start charging at 10am every day at 28A (~7kw)
