Solar Panels and Electric Vehicles
The main question often asked by homeowners new to solar panels and electric vehicles is:
“Can electric vehicles be charged by solar panels?”
The answer is, yes! Yes, a home solar system can charge electric vehicles. There are two options for charging your electric vehicle from home. The first option is to go through your utility provider and purchasing an electric charging station. However, you will pay more on top of your current electric bill to charge your car. This could get pretty expensive, that is depending on how much you drive your vehicle.
The second option is cleaner because you can power it with solar panels. Let’s say you already have solar. If this is the case, you just add the panels needed to charge your car to what’s required for the home. Perhaps you owned an electric vehicle before going solar, then the required panels should have already been calculated.
If you purchased your electric vehicle after going solar then the great news is the required panels are minimal.
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 the Miles-Per-Gallon equivalent or also known as MPGe. You can find this at fueleconomy.gov.
Step 2: Once you know the kWh, then you just need to calculate how many miles do you drive per day?
Step 3: Estimate (round up) how many miles you will drive per year.
For instance, if your car rating is 30 kWh/100 miles that means you’re only using 7.5kWh per day when driving 25 miles a 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 required for your home and vehicle, an electric vehicle charger will need to be installed. You can purchase these just about anywhere now, your car dealership will sell them, you can purchase them off Amazon, eBay, Craigslist, even Walmart now sells them.
If you’re in the process of installing solar, make sure the inverter installed can handle the amount of power needed 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’ll be greener because with fewer vehicle and electricity emissions you’re positively affecting the environment.
If a solar system was installed to charge the car then this second purchase can be claimed on taxes.
You will reduce the cost of your car significantly by not paying for gas and by claiming a bonus credit on your taxes.
