Electric vehicles (EVs) are transforming the transportation landscape worldwide. As concerns about climate change and fossil fuel dependence grow, more people are turning to electric cars for a cleaner, greener commute. At the same time, renewable energy sources like solar power are gaining momentum in homes and businesses. This convergence has sparked interest in innovative solutions that combine EV charging with solar energy generation — and one of the most promising of these is the solar carport.
A solar carport is a covered parking structure fitted with solar panels on the roof, allowing you to produce clean electricity right where your vehicle is parked. But can it really charge your electric car efficiently and conveniently? This article will answer that question in depth, explaining how solar carports work with EVs, what charging speeds you can expect, and how to optimize your system for day and night use.
Solar carports function just like traditional solar panel systems, but with a dual purpose: providing shelter for vehicles while harnessing sunlight to generate electricity. The panels mounted on top of the carport capture sunlight and convert it into direct current (DC) electricity. This electricity then passes through an inverter, which converts DC into alternating current (AC), suitable for home or commercial use, including EV charging.
When you connect an EV charging station under the solar carport, the electricity generated by the panels can be fed directly to the car’s battery. The power flow can either be used immediately, stored in a battery system for later use, or sent to the grid if your system is grid-tied.
Most solar carports are grid-tied, meaning they remain connected to the utility grid. When solar production exceeds immediate demand, excess electricity is sent back to the grid, often earning credits or payments through net metering programs. When the solar output is low—such as at night—the EV charger can draw electricity from the grid to continue charging the vehicle.
In off-grid systems with battery storage, energy generated during the day is stored in batteries and used later to charge EVs at night or during cloudy weather. This option requires more upfront investment but offers energy independence.
The effectiveness of charging an EV from a solar carport depends largely on the system’s size and the EV charger’s capabilities.
Residential solar carports typically range from 3 kW to 10 kW, while commercial installations can be much larger. A 5 kW solar carport might produce around 20 kWh of electricity on a sunny day, enough to add roughly 60-70 miles of range to an electric car with average efficiency.
For example, Tesla Model 3 and Nissan Leaf have energy consumption rates roughly between 250 to 350 Wh per mile, so 20 kWh could provide:
20,000 Wh ÷ 300 Wh/mile = approximately 66 miles of driving range
EV chargers are classified into levels based on power output:
Level 1 chargers use a standard 120V household outlet and provide about 2-5 miles of range per hour of charging.
Level 2 chargers operate on 240V and can deliver 10-60 miles of range per hour.
DC Fast Chargers (Level 3) supply very high power, charging vehicles to 80% in 20-40 minutes but are less commonly paired with residential solar carports.
Solar carport systems are most often paired with Level 2 chargers. The solar power output and charger capacity together determine how fast your EV charges from solar energy alone.
For instance, if your solar carport produces 5 kW of power and you have a 7 kW Level 2 charger, your vehicle will charge slower during peak solar hours compared to a scenario with grid backup.
Charging speed depends on sunlight availability. During peak sun hours, a solar carport can provide substantial energy, but in early morning or evening, solar production falls and charging from solar alone slows down unless supplemented by grid or battery storage.
One limitation of solar power is its dependence on daylight, while EV charging often occurs overnight. To address this, many solar carport owners install battery storage systems such as Tesla Powerwall or LG Chem batteries.
These batteries store excess solar energy produced during the day for use at night. This means you can charge your EV overnight using clean, stored solar energy instead of grid electricity, maximizing your use of renewable energy and reducing costs.
While adding batteries increases upfront cost, it also enhances energy resilience and independence. The size of the battery needed depends on your daily EV charging requirements and typical solar production.
Many EV owners install home wall chargers inside their garages, but solar carports offer some unique advantages:
Integration with Solar Generation: Solar carports directly couple renewable energy production with EV charging, reducing electricity costs.
Vehicle Protection: The carport shelters your vehicle from sun, rain, and snow.
Flexibility: Solar carports can be installed where rooftop space is limited or unavailable.
Scalability: Larger commercial carports can serve multiple vehicles simultaneously.
However, solar carports require suitable outdoor space and investment in solar infrastructure, whereas home wall chargers are simpler and cheaper to install but rely entirely on grid electricity unless combined with a rooftop solar system.
For many EV owners, the best solution might combine a solar carport with a home charger and battery storage to optimize energy use.
Most electric vehicles on the market today are compatible with solar charging through Level 2 chargers connected to solar power sources, including solar carports. Popular EVs well-suited for solar charging include:
Tesla Model 3, Model Y, Model S, Model X: Tesla vehicles are known for their high efficiency and come with the Tesla Wall Connector for home and solar carport charging.
Nissan Leaf: One of the most affordable EVs, with good compatibility with Level 2 chargers.
Chevrolet Bolt EV: Offers long range and quick charging.
Ford Mustang Mach-E: Supports Level 2 and DC fast charging, ideal for solar carport setups.
Volkswagen ID.4: Compatible with home and solar charging solutions.
When selecting an EV for solar charging, consider battery capacity, charging speed, and daily driving needs. Vehicles with moderate battery sizes may be more practical for charging primarily from a solar carport.
Can a solar carport really charge your electric car? Absolutely. Solar carports offer a smart, eco-friendly solution to power your EV while shielding your vehicle from harsh weather. Although charging speed and capacity depend on your solar setup, location, and sunlight availability, pairing a solar carport with a Level 2 charger can provide significant daytime driving range. Adding battery storage further extends charging into nighttime hours, increasing convenience and independence.
Compared to traditional home chargers, solar carports combine the benefits of clean energy use and vehicle protection, making them an ideal choice for EV owners who want to save on energy costs and reduce their carbon footprint.
