The main question often asked by customers new to solar panels and electric vehicles is:
“Will my Solar Panels also charge my Electric Vehicle?”
The answer is, yes! Yes, you can charge your electric vehicle with your home solar panels.
There are two options for charging your electric vehicle from home.
Option One is going through the electric company and purchasing an electric charging station. You will pay more on top of your current electric bill to charge your car. This can get pretty expensive depending on how much you drive your vehicle.
Option Two is with solar panels. Since you already have solar, you will only need to factor in how many solar panels you need to charge the car and add that into how many you need total for your home. If you owned your electric vehicle prior to solar installation, the number of solar panels necessary should have been calculated for you.
If you purchased your electric vehicle after your solar panel install, the good news is the number of panels you need is very small.
Here is a step by step guide to determining how many solar panels you will need for your vehicle.
Step 1: Determine how many kilowatt-hours it takes your car to go 100 miles. This is called Miles-Per-Gallon equivalent or MPGe. You can find this at fueleconomy.gov.
Step 2: Once you know your kWh, ask yourself how many miles you drive per day.
Step 3: Estimate (round up) how many miles you will drive per year.
Example: If your car rating is 30 kWh/100 miles and you only drive 25 miles a day than you’re only using 7.5 kWh per day. That’s around 2,700 kWh energy usage in a year. With this estimate, you can add up your household usage and add the required number of panels to your system.
Once you have the solar panels you need to power your home and vehicle, you will need to purchase and install an electric vehicle charger. You can purchase these just about anywhere now. Your car dealership will sell them, you can purchase them off Amazon, eBay, Craigslist, even Walmart.
If you are in the process of solar panel installation, that the inverter you install can handle the amount of power you will be using for your vehicle charger. If you already have a solar panel system installed, you will need to install a new inverter that can handle more power coming from the panels.
On average, you will need about 10 solar panels per electric vehicle.
That’s about it for the nuts and bolts of charging your electric vehicle using solar panels.
Here is some added bonus to electric vehicle charging with solar panels:
The first is you aren’t paying the electric company to charge your vehicle if set up right the electric company may even give you credits for solar they purchase from you.
You will support the environment with fewer vehicle emissions and fewer electricity emissions affecting the environment.
If you already have a Solar System installed and you claimed the Solar purchase on your taxes and you install another system to charge your car then you can claim the second solar panels purchase on your taxes also and save even more money.
You will reduce the cost of your car a great amount with not paying for gas and receiving bonus credit on your taxes.
Just as you did before you purchased your Solar Panels, make sure you do your research on your best options for Electric Vehicles, Chargers and Solar Systems needed. Make sure you are purchasing solar panels that will meet your needs and will save you money in the long term.
