Introducing the revolutionary electric vehicle (EV), a symbol of sustainable transportation and the future of mobility. As our world revolves towards eco-conscious solutions, EVs have emerged as a cornerstone of this movement, offering emissions-free travel powered by electricity.
These are successful inventions to decrease the use of fossil fuels, and in the past decade, they have become a primary vehicle in various countries. But among the buzz surrounding these vehicles, a common question arises: Can you charge an EV with solar power?
Yes, you can. As solar panels convert the sun’s renewable energy into electricity, this process will charge your EV. But there are a few factors and calculations of daily driving range and energy consumption you must understand to get sufficient energy to charge your EV from the solar panels.
Here, we dive deeper into the symbiotic relationship between solar energy and electric vehicles, exploring the feasibility, benefits, and considerations of this eco-friendly charging solution.
Also, find out all the mechanisms by which you can charge your EV with solar power. Let’s dig in!
What Is Solar Power?
Initially, grasp what solar power is. Solar power is a remarkable form of renewable energy received from the sun’s abundant light and heat. It involves harnessing the sun’s energy through specially designed solar panels, often found on rooftops or in dedicated solar farms. These panels are equipped with photovoltaic cells, which act as the workhorses of solar power generation.
When sunlight strikes these photovoltaic cells, it triggers an appealing process. These cells contain semiconductors, usually made of silicon, which absorb the energy from the sunlight. As a result, electrons within the semiconductor become excited and start moving, generating an electric current.
This direct current (DC) is then transformed into the alternating current (AC) used in our homes and businesses by passing through an inverter. Utilizing solar power produces no harmful emissions, perfect for a cleaner and healthier planet.
Can You Charge an EV With Solar?
The notion of charging an EV with solar power is an increasingly popular and green approach in today’s society. Unlike traditional vehicles relying on fossil fuels, EVs operate solely on electrical power. This leads to the natural question: Can you charge an EV with solar?
EV charging with solar power is possible, and it has become an ideal charging option in many countries. The process involves tapping into the sun’s energy using solar panels. These panels, commonly mounted on your rooftops or dedicated structures, tackle sunlight through photovoltaic cells.
When sunlight hits these cells, it triggers a magical transformation, which is basically the conversion of sunlight into electricity. This electricity is then directed to charge the EV’s battery, providing a clean and sustainable power source for your electric vehicle.

So, in a general sense, you can easily charge your EV with solar energy. But there are some minor aspects you must learn to get a sufficient amount of charging that is fine to fulfill your daily driving range.
Calculating the Power of the Solar Energy that EVs Needs
Although solar energy is renewable, it has a limit on how much it can generate each day as the sun doesn’t shine all day long. There is an easy way to calculate how much-fixed energy your EV will need from solar panels.
First, know the below things before calculating the regular natural energy needs.
- The total range of your EV can go up after a full charge.
- Capacity of your EV
- Range of miles you drive each day
- Ideal Sunlight (Insolation) hours in your area
Now, take a notepad and start the calculation with the kilowatt-hours of energy consumption per mile by dividing the capacity of the battery (measured in kilowatt-hours) by the total range of your EV.
For example, if your EV has 73.5 kWh and the total range is 358 miles, the result will be [73.5 kWh / 358 miles = 0.2053 kWh per mile]. It means your car consumes 0.2053 kW of energy per hour after every driving session.
After measuring the daily consumption, we will find out how much energy our car will need every day. Suppose, you drive 50 miles each day. So the required charging energy will be [50 × 0.2053 = 10.3 kWh per day]. It means your EV uses 10.3 kW of electrical energy after driving each day.
Eventually, we will calculate the solar system size. Your car needs 10.3 kWh every day, and the estimated sunlight time in your area is about 5 hours. So, the solar system size will be [10.3 kWh/5 hours = 2.03 or 2.1 kW]. It means you will need to install solar panels that can provide at least 2.1 kW of energy in an hour.
The solar system calculation will help you decide how many solar panels you will need to only charge the EV. But you might not get the same amount of energy every day if there are any weather issues, and a minimal amount of energy is always lost while converting from AC to DC or vice versa.
So, install solar panels, which can produce a bit more energy than the calculated daily needs for EV charging.
Factors Related to EV Charging With Solar
There are some factors you must determine before charging your EV with solar power. You will be able to get the maximum amount of renewable power for your car by understanding them. Take a look at the below factors:
Sunlight Availability
Before diving into solar-powered EV charging, assess the availability of sunlight in your location. Areas with more sunlight tend to yield better results, ensuring efficient energy generation from solar panels.
Energy Consumption of an EV
Understand the energy requirements of your electric vehicle from the calculations we have done. Different EV models have varying energy consumption rates, and knowing this information helps determine the number of solar panels needed for effective charging.
Roof Space and Solar Panel Capacity
Measure the available roof space for installing solar panels. The capacity of the solar panel system should align with both your energy consumption needs and the available rooftop area to maximize efficiency.
Battery Capacity and Charging Time
Consider the capacity of your EV’s battery and the desired charging time. This factor influences the size of the solar power system required to meet your charging needs efficiently.
Direction and Tilt of Solar Panels
Optimal energy generation depends on the orientation and tilt of solar panels. Ensure they are strategically positioned to receive the maximum sunlight exposure throughout the day, enhancing overall charging efficiency.
