The number of electric vehicles (EVs) on the road is growing rapidly as more drivers realize the benefits of going electric. Not only are EVs better for the environment, but they also save drivers money on fuel and maintenance costs in the long run. One smart way to power your EV is by installing solar panels. Using solar energy to charge your electric car is a win-win – you’ll be using clean, renewable power while also maximizing savings. Here’s a closer look at why powering your EV with solar makes sense.
Slash Your Electric Vehicle Charging Costs
For many households, one of the biggest deterrents to buying an EV is the higher upfront cost compared to gas vehicles. However, when you account for all the costs associated with owning and fueling a car over its lifetime, EVs can save you thousands of dollars. This is especially true when you use solar energy to charge your car.
Charging an electric vehicle at home costs around half as much per mile compared to gas vehicles. The average cost to charge an EV is just $0.04 to $0.06 per mile. With gas prices fluctuating wildly, powering your car with electricity is more affordable and predictable. By using solar power from panels on your roof, you can reduce EV charging costs to near zero. The sun’s energy is free once your solar system is paid off.
Using Solar Energy to Charge Your EV
Solar panels convert sunlight into usable electricity that can power your home, appliances, and vehicles. The amount of solar energy available depends on your region and local weather, but most places in the U.S. have enough sunny days to make solar worthwhile.
When solar panels are connected to the grid, any excess energy they produce is sent back to the utility. This results in a credit on your electricity bill through a net metering agreement. If you own an EV, you can use this solar credit to fuel your car and reduce total electric costs. You’ll maximize savings by timing your EV charging during sunny midday hours when solar production peaks.
A typical 6 kW solar system produces an average of 20-30 kWh of electricity per day. This is more than enough to power an EV that uses around 25-35 kWh per 100 miles driven. With enough solar capacity, you could earn enough credits to charge your EV for free.
Increase Your Energy Independence
In addition to saving money, powering your electric vehicle with solar provides greater control over your energy supply. With gas prices fluctuating and electricity rates on the rise, energy costs are unpredictable. But when you tap into the sun’s energy with solar panels, you can take charge of your transportation fuel costs.
Solar energy is always available during daylight hours and not subject to volatile price swings. By investing in a solar and EV ecosystem, you’ll have access to clean, renewable fuel at low, predictable rates for decades. This energy independence and stability will pay off over the lifetime of your vehicles.
Cut Your Carbon Footprint
Going green is another major motivator for many new EV buyers. Electric vehicles have a smaller carbon footprint compared to traditional gas cars. However, the emissions impact depends greatly on how the EV is charged.
Charging your electric car using a coal-powered grid often results in higher emissions. But when you charge your EV battery using clean solar electricity, you can drastically reduce your carbon footprint from driving. Solar power emits zero greenhouse gases during operation.
Each gallon of gas used by a typical car produces around 8,887 grams of CO2. For an EV powered by renewable solar energy, emissions from driving can be nearly eliminated. You’ll be doing your part to fight climate change by going solar.
Earn Tax Credits and Incentives
To encourage more environmentally friendly transportation, federal, state and local governments offer tax credits, rebates and other incentives for electric vehicles and solar power installations.
The federal tax credit for EVs is worth up to $7,500 based on battery capacity. There is also a federal solar tax credit worth 30% of installation costs. Additional state-level incentives can save you thousands more on your electric car and solar panels.
Utilities are also joining the push for emissions-free driving by providing special EV rates, solar rebates and charging station funding. Check with your utility and local government to identify all possible EV and solar incentives available in your area. The savings can make going green very rewarding.
Enjoy Seamless Integration
Charging your EV using solar energy is made even simpler with smart technology and integration. Many EV chargers and solar inverters communicate to optimize charging times and maximize solar usage.
With a smartphone app, you can monitor your solar production, track EV charging status, control charging times, and view energy usage. Advanced home energy management systems automate the process of routing excess solar to your vehicle battery as needed.
Modern EVs can even send signals back to your house to adjust home energy use and charging speed based on driving patterns and solar availability. This seamless integration means you’ll spend less time worrying about charging and more time enjoying emission-free driving.
Take Full Advantage of Your Solar Panels
Investing in an electric vehicle is the perfect opportunity to also go solar if you haven’t already. Powering your EV with home solar energy enables you to unlock the full value of your panels. You’ll slash your electric bill, tap into clean power, reduce environmental impact, and maximize savings.
The incentives and tax credits available now make going solar and electric more affordable than ever. Boost your home’s sustainability and minimize your driving costs for years to come by harnessing renewable energy from the sun to power your EV. The transition to emission-free, solar-powered transportation is here. Take charge and make the switch to clean driving on sunshine.

How can I use solar panels to charge an electric vehicle?
You will need to have solar panels installed on your home that are connected to the electrical grid. The solar energy that is collected from the panels is fed into your home’s electrical system. You can then use this solar-generated electricity to charge your EV by plugging it into an outlet, just as you would with grid electricity.
What equipment do I need?
You will need a sufficient number of solar panels installed on your home to produce enough energy to meet your EV charging needs. You’ll also need an EV charger installed where you park your vehicle. A bi-directional charger allows you to both charge from and send energy back to the grid as needed.
How many solar panels do I need to charge an EV?
Most EVs require about 25-35 kWh of electricity to travel 100 miles. To power an EV that drives 1,000 miles per month, you’ll need a solar array sized around 3-4 kW. More driving and fewer sunny days would require a larger system.
When should I charge my EV to use the most solar power?
Charge your EV during the sunniest parts of the day, typically between 10 am and 4 pm, to maximize your solar usage. Avoid charging overnight when solar production is low unless you have a solar battery. Orient your panels to the south if possible to capture the most sunlight.
Will I have enough solar in the winter to charge an EV?
If sized properly, your solar system should meet your EV charging needs year-round, even when the days are shorter. Just be sure to charge when the sun is out. Batteries can supplement solar when needed.
What incentives are available for solar EV charging?
The federal government offers a tax credit for 30% of solar installation costs. Some utility companies offer special EV rates and rebates for installing solar and charging equipment. Your local government may provide additional solar incentives.
How can I monitor solar production and EV charging?
Solar inverters and EV chargers have built-in monitoring capabilities and apps to view your energy usage and charging history. Smart chargers automatically adjust charging speed and times to sync with solar output.
