Electricity Usage:
We can help you determine the electricity usage of your electric vehicle, or future one, when sizing your solar system. We would need to know the electric vehicle you have, or are planning to purchase, and your average daily mileage. It’s that simple! If you would like to prepare your solar system for your future electric vehicle you can install an inverter that can handle more power, utilize microinverters, add additional panels to your current system, or build an additional solar system.
Inverter:
If you install an inverter that can handle more power, you will want to know the number of panels that you plan on adding. String inverters are the most common with solar systems and the solar panels are arranged in strings which feed into the inverter. The inverter is then sized for the output of those solar panels only. Therefore, if you go this route you will need to make sure that the inverter can handle your current solar panels and the ones you plan on adding in the future.
Microinverters:
Another option is to install microinverters with your solar panels. In this scenario, each of your solar panels has its own inverter. Therefore, adding extra panels in the future is easily done without needing to have an inverter that can handle more power than what you originally installed.
Additional Solar System:
Installing an additional, smaller, solar system is also an option but only if you have the room for it. You could install a smaller roof or ground mount to meet the energy needs of your electric vehicle. The good news is that you can claim the federal tax credit for solar more than once so you can save even more! You can also initially build a larger system that will accommodate your future needs. However, some utilities will not approve a system that is significantly larger than your current needs.
Energy Efficient:
Lastly, there are other ways that you can make your home more energy efficient. This will in turn make more room for your future electric vehicle energy needs. You can switch out light bulbs for energy efficient ones, use a programmable thermostat, upgrade your appliances, and improve your home’s insulation.
