When getting a solar PV system installed on your home today, it is also considered advisable to get a smart monitoring system. Not only will this help you ensure that your solar panels are operating efficiently and in good working order, it can also help determine how your electricity is used.
Your system can be set up so that excess electricity created when your solar PV array is generating more power than is being used in your home is diverted to peripherals. This might be a solar battery, immersion heater, or it could be sent to a plugged in electric vehicle.
In this way your vehicle could use solar energy to charge during the day, and be set to finish charging from grid power at nightime, using the cheaper rates.
However, the majority of people will have their car charging primarily in the evening or night-time. With that, in order to make use of the solar electricity generated during the day, you’re going to need to invest in a battery storage system.
Batteries for home electricity are fairly new to the market, and allow for the storage of electricity produced by your solar panels, which is not used at the time it is generated. Otherwise, excess electricity is generally pumped back into the grid.
This means that if you are away from the house during the day, at work or elsewhere, you can still use your solar panels to charge your EV.
