Excess Solar Power Charging

20

Description

When a house’s solar array is generating more power than the house consumes, have the car use the excess energy to charge the batteries. This means the charge rate will vary depending on how much excess energy is being created. The timer would still be used to ‘top’ off the power in non-peak hours.

This feature is useful in regions where the electric company either provides no compensation for excess power generation, or more commonly, a far lower rate of compensation than rates charging in non-peak hours (i.e. midnight to 6 am).

Competitive/Pricing/Notes

This system would have some outside costs – as the solar and main house power must be monitored, and a means (likely WiFi) to communicate with the car. Retail products that perform similar actions typically cost under $500. The car itself would require some additional software, but no hardware changes.

This is a feature the power controller of the solar panels need to support. The car would only be a consumer of where the controller decides to deliver power (IMHO).
The hardware already exists to do this called Zappi.

Zappi is a mode 3 charging station  ... If you have solar panels, or a wind turbine micro generation system, together with a Tesla then you could consider Zappi as a charging solution that does this functionality
Zappi looks to be a good solution for Europe. They only offer Type 1 and Type 2 connectors so far.  For those that want more information: https://myenergi.uk/product/zappi-product/
