How to Charge EV with Solar Power.
Here are the procedures to charging your electric car using solar panels:
Step 1: Determine how much kWh your car requires based on your driving patterns. You may make an educated guess by calculating the average amount of miles driven every day.
Step 2: Determine how many solar panels you’ll need to generate that kWh. To charge an electric automobile, you’ll need between 10 and 17 kWh of power every day.
Step 3: Acquire solar equipment capable of producing that much power. You’ll need a solar energy system and all of the necessary equipment.
Step 4: Purchase a Level 2 vehicle charger.
Cost of Charging EV Directly from Solar Panels.
According to a survey done by consumer solar panel setup reviews site SolarReviews, using residential rooftop solar to charge an electric car in the US costs only 415 per year, opposed to 662 on-grid electricity at residential and 1,058 with a public EV charger. The survey also discovered that filling a petrol car’s tank might cost up to 1,260 per year.
Rooftop solar panels, a centralized string converter that converts the DC output of the solar boards to AC, and a level 2 EV charger are typical components of a solar EV charging arrangement. According to SolarReviews, five sun panels are required to charge an EV.
Solar roof panels have a lower long-term expense than buying power from the grid, where the average kWh of electricity price is growing over time in practically every country.
What Do you Need for a Solar Car Charging Station for Home?
Aside from a solar panel, you’ll need a mechanism to store the energy generated by the solar. There are several choices for home batteries on the market currently.
Station for Charging
You will also require a charging station (often placed in your garage or entrance) where you can connect to your automobile. We suggest level 2 chargers since they charge significantly quicker.
A centralized string inverter that converts the solar arrays’ Dc power to AC, or segments and sub that convert the power of each panel to AC and transmit it to a combiner box that links to your main AC board.

Solar charging stations for electric vehicles (EV’s)
The combination of solar energy and electric vehicle (EV) charging is the key in drastically reducing our dependence on fossil fuels. Electricity comes from a variety of sources and it’s crucial that electric vehicles will be powered by renewables. Electric cars are becoming immensely popular and coming years we expect nearly anyone who owns a solar energy system will install a solar charging station at its home. For this to happen we’ll need a fundamental change in how we think about refueling our cars and a natural evolution of our energy infrastructure.
What is the change in thinking that we need?
Most people believe we need to be able to charge our plug-in electric vehicle (PEV) or plug-in hybrid electric vehicle (PHEV) within 2-4 minutes, similar to pulling over at a gas station and filling up your car with gas. Even though Tesla’s super chargers are trying to do exactly that, electric charging is going to be different from what people are used to. From now on most people will charge their electric cars with their home solar charging station while they sleep or while they’re at work. Solar charging stations will be used for topping off” an electric car, giving the owner enough battery charge to return home where she can fully recharge the EV.
Fact: Just 10 solar panels should provide roughly enough electricity to power 21,000 kilometers of electric driving each year. How’s that?solar energy charging for electric vehicles
On-Grid solar charging stations
A grid-tied solar energy system is the most straight forward way to charge your electric car with solar energy. A grid-tied solar energy system will feed the power to the grid, regardless of whether your home needs the power at that moment or not. So when your solar energy system is feeding to the grid, and you are at your office, the electric power generated at home is sold to the utility company. You’ll get that power back from the utility company in the form of a credit. When you come back from work and park your car at home, you can use that credit to re-charge your car at home.
A conventional electric vehicle charger that is connected to the grid “will almost always be cheaper” than an Off-Grid charger that stores the power in batteries.
Off-Grid Solar charging station
An Off-Grid electrical car charger can also be named Electric Vehicle Autonomous Renewable Charger There’s no connection to local utilities required. The solar panel array will feed the battery energy storage system and the entire power needs are drawn from this storage system. Off-grid electrical car chargers can be placed virtually anywhere, as there’s no need for a connection to the electrical grid. The independent solar array canopy catches quite some wind, and for that reason a solid foundation is required. Some off-grid solar energy chargers have a heavy steel base plate that functions as ballast. Those are extremely easy and quick to install, as no foundation or digging is required.
Most electric car owners will completely charge their EV batteries at night at their homes. Therefore for most solar charging stations, the objective is not to fully charge an electric car, but to allow several cars to “top off” their batteries.
If you are still driving a conventional car using 100 years old technology (gas), sell that thing and be part of the future with an EV! As you know electricity comes from a variety of sources, including dirty fossil fuels, and now is the time to push for renewables to take its place. Solar charging stations for home and commercial use will play a major role in powering electric vehicles with renewable energy.

Top Questions About Solar EV Charging, Answered
Everyone knows that solar power is a highly sustainable source of electricity, and the cost advantages can be enormous. Beyond those two facts, however, questions abound. Here are answers to questions frequently asked by EV owners about solar EV charging.
How do solar charging stations work?
Solar panels convert sunlight into DC (direct current) electricity. A connected inverter changes the DC electricity received from the solar panels into the AC (alternating current) electricity needed for EV charging. The AC electricity goes to a distribution board to be used by power devices, and any surplus electricity is stored in a battery or fed to the grid for use by others.
A Smart EV charger takes the solar-generated AC electricity and charges your EV directly from the distribution board or a battery. The charger can use 100% solar power or a combination of solar and grid power to achieve the desired charging speeds. When AC power flows into your EV through the charging cable, your EV’s onboard charger converts it back into DC electricity.
What are the benefits of having solar EV charging stations?
Although most people think that the benefits of a solar EV charging station revolve around sustainability and cost savings, there are six primary benefits:
Energy Costs: Solar-generated electricity is almost universally less expensive to purchase than that obtained from any grid in the U.S. Many people find that their monthly power bills drop by as much as half.
Net Metering: Electricity generated by solar panels during the day can be pushed to the grid for credit against your power usage. If you can push more power to the grid than you use yourself, you can sell the surplus to the utility provider at a profit.
Zero Carbon Footprint: Between 40-80% of national grid power in the U.S. is still manufactured from fossil fuels and other non-renewable energy. However, a home solar EV charging station guarantees a 100% carbon-neutral footprint.
Convenience: Public charging stations can be inconvenient, particularly in areas that don’t have very many. Even a home-based station can be problematic if powered off the grid and there’s an outage. Home solar charging stations are the ultimate convenience and provide insurance against grid outages.
Tax Credits and Incentives: There are several Federal, State, and Local tax credits and incentives for EVs, EV charging, and solar EV charging. Start your search with the U.S. Department of Energy’s Alternative Fuels Data Center.
Increased Property Value: Studies show that homes with installed solar systems sell more quickly and at a higher price than homes that don’t. According to the National Renewable Energy Laboratory, home values increase by 20 for every 1 that a home solar system saves the homeowner on their electrical bills. The Zillow real estate website calculates that homes with solar panels sell for an average of 4% higher than those without them.
How can I charge my EV at home using solar panels?
- Solar panels mounted on your roof in metal racks
- A central string inverter combining DC output to AC, or micro-inverters that convert each panel’s output to AC and send it to a combiner box
- A Level 2 EV charger
Many vendors specialize in installing home solar systems to power households and electric vehicles. Three better known include Freedom Solar (12 locations nationally), Sunpower Solar. and Sunnova (both servicing all 50 states). For DIYers, Electric City outlines a six-step process for installing a solar at-home EV charger.
How many home solar panels does it take to charge an EV for daily use?
- How many miles do you drive on an average day
- How many hours of sun do you get on an average day
- The wattage of your solar panels
- Your EV’s fuel efficiency
You own a Tesla Model Y and drive it about 37 miles on a typical day. The rated fuel efficiency of a Tesla Model Y is 3.82 miles per kWh. The area you live in gets an average of 4.5 hours of sunlight daily. You’ll need to install six solar panels (each 400w) to provide the necessary power to charge your Tesla at home.
Say that, instead of a Tesla Model Y, you drive a 2014 Toyota RAV4. The Toyota has a rated fuel efficiency of 2.17 miles per kWh. With all other factors matching the Tesla example above, you would need ten 400w solar panels to produce enough power to charge your EV for daily use.
information on calculating the number of panels needed to handle both home power needs and EV charging requirements is available at TheSolarNerd.com.
How long does it take to charge an EV using solar panels?
Not surprisingly, the answer to this question varies significantly based on solar panel wattage, type of solar panel controller, battery AMPs, battery discharge depth, and more.
For example, let’s say you are charging a 12V 50Ah lithium battery that’s 80% discharged. You’re using a 100W solar array with an MPPT controller. You need six peak sun hours to charge your battery fully. If your location gets three peak sun hours daily, you’ll need two days to achieve a full charge.
- A charging time calculator that determines the number of peak sun hours you will need for your specific parameters
- A peak sun hours calculator that determines the average peak sun hours received by your location
What’s the best time to charge an EV with solar panels?
You want to charge your EV at the time of day that maximizes both the financial return and environmental benefit of your solar panels. This time depends on whether you have a time-of-use (TOU) plan with your electric utility company or a Net Metering/Net Billing plan.
With a TOU plan, the rate homeowners pay for electricity depends on what time they use it. Rates are less during times of lower demand. Net Metering plans give solar homeowners credit for excess power they produce that’s dumped into the grid based on the retail rate. Another option, Net Billing plans, pay the homeowner based on the wholesale rate.
- Net Metering plan with TOU – Charge during off-peak hours (usually overnight).
- Net Metering without TOU – Charge at any time of day, but doing so during off-peak hours will minimize carbon intensity.
- Net Billing with TOU – Charge during off-peak hours if the savings are greater than the difference between your retail and wholesale rate; otherwise, charge when your panels are producing power (while the sun’s out).
- Net Billing without TOU – Charge when your solar panels are producing power.
Most late-model EVs can be set to charge automatically at a specific time, making it easier for owners to target lower-cost periods. If your EV doesn’t, you can buy an EV charger with a built-in timer.
What are portable solar panels for EV charging?
Portable solar panels for EV charging are small, lightweight options for EV owners who want to charge their vehicles at home without installing a permanent solar panel system.
Portal panels are easy to install, needing little more than a connection between the panel and your EV battery. For that reason, you can charge your EV from anywhere you go using cheap, renewable solar energy. Like a permanent solar panel system, portable solar panels use photovoltaic cells to absorb the sun’s energy and convert it into electricity.
Light Tower Pro lists a variety of the best portable solar panels for EV charging. These include models by well-known manufacturers, including Bluetti, EF Ecoflow, Goal Zero, Jackery, Renology, and Rockpals.
What are off-grid solar EV chargers?
Off-grid solar EV chargers store solar-generated power in batteries for use on demand to charge electric vehicles. They do not require plugging into the grid.
Unlike portable solar panels, which are small and lightweight, off-grid solar EV chargers are usually close to the length and width of a full-size automobile, accompanied by a box-like structure containing the storage batteries.
The power generated and sold is usually less expensive than power purchased from the grid, especially during peak periods.
