Eco-Friendly Driving: Charge E-Car With Mini PV System

Eco-Friendly Driving: Charge E-Car With Mini PV System

In today's environmentally conscious world, the idea of powering electric vehicles through solar energy is gaining traction, promising a sustainable and renewable energy source. This article explores the exciting possibility of employing a small-scale photovoltaic (PV) system specifically for charging electric cars.

We'll look into how much power is actually needed to charge an electric vehicle, assess whether a mini PV system can meet these requirements, and outline the steps you'd need to take to implement such a system yourself. What's more? We'll discuss some of the common challenges that might come up when you charge E-Car with mini PV system and provide a solution. Let's get started!

What Wattage Does An Electric Car Need To Charge?

The wattage required to charge an electric car predominantly depends on the charger level being used. On average, Level 2 EV chargers, which are common for residential use, utilize about 7,200 watts, or 7.2 kilowatts (kW), of electricity. The consumption can vary as these chargers can operate between 32 and 40 amps and are usually connected to a 240-volt outlet. For instance, assuming an average driving distance of 14,000 miles per year, the daily distance is 38.4 miles and the usual daily consumption stands at 13.4 kWh, which translates to monthly usage of approximately 408kWh for the average driver.

Can a Mini PV System Really Charge an Electric Car?

Given the energy needs, a mini photovoltaic (PV) system can potentially charge an electric car. However, its effectiveness hinges on various factors, including the size of the system and the vehicle's battery capacity and efficiency. A standard domestic solar PV setup, with an average output, could theoretically supply enough electricity to support EV charging, although it might take significantly longer to fully charge the vehicle compared to a dedicated EV charging point.

Typically, about 12 average-sized solar panels rated at around 600 watts each are required to meet the power needs of a Level 2 EV charger. Therefore, a suitably sized mini PV system could indeed contribute to the charging of an electric vehicle, particularly if it's supplemented with a battery storage system or used in conjunction with grid electricity.

Setting Up Your Mini PV System for E-Car Charging

Now that a mini photovoltaic (PV) system can facilitate the charging of electric cars (E-cars), it's time to set up one to harness renewable energy while reducing your carbon footprint. Here’s how you can get started:

  1. Assessment and Planning:Evaluate your daily and monthly EV energy consumption. Consult with a professional to estimate your home’s solar potential.
  1. System Sizing:Based on your consumption and solar potential, size your PV system to meet your EV charging demands, ideally incorporating a buffer for efficiency losses and potential expansion.
  1. Permitting:Secure necessary permits and approvals from local authorities and utility providers, adhering to all regulations and standards.
  1. Installation:Choose reputable solar installers for the PV system setup. Ensure optimal placement and orientation for maximum sunlight exposure.
  1. Integration:Connect the PV system to an EV charging station, integrating suitable inverters and battery storage systems to manage energy flow and storage.
  1. Commissioning and Testing:Once installed, thoroughly test the system to ensure optimal operation and efficiency for EV charging.
  1. Monitoring:Implement a monitoring system to track energy production, consumption, and system health, adjusting settings as needed for efficiency.

Common Issues When Charging An E-Car With A Mini PV System

Here are some common issues when charging an electric car with a mini photovoltaic (PV) system:

  1. Insufficient Power Output:The small Photovoltaic (PV) system may not generate enough power to charge the electric vehicle (E-car) efficiently. Charging could take much longer compared to using traditional grid-sourced electricity.
  1. Weather Dependency:Solar power relies heavily on weather conditions. The mini PV system's output can drop significantly during cloudy or rainy days, compromising the charging efficiency of the E-car.
  1. Limited Charging Times:PV systems essentially operate during daylight hours. Limited or no charging opportunities exist after sunset unless the system includes a robust power storage solution.
  1. Battery Storage Issues:Mini PV requires a storage mechanism (like batteries) for storing and then providing power. If the storage capacity is inadequate, it won't be able to provide the required power for charging the E-car.
  1. Initial Investment and Maintenance Costs:The setup cost for a mini PV system can be high, and maintenance costs over time can outweigh the benefits of charging an E-car.
  1. Compatibility Issues:Not all E-cars and charging stations are compatible with solar charging systems. Cross compatibility checks between the PV system, charging station, and the E-car are essential.
  1. Infrastructure and Space Requirements:The installation space required for mini PV systems might be significant. Also, local building codes and regulations might restrict the installation of these systems.

While setting up a mini photovoltaic (PV) system for E-car charging presents challenges like insufficient power output, dependency on weather, and compatibility issues, the Anker SOLIX Balcony Solar Power System (820W) with 600W/800W Microinverter offers a robust solution.

The smart monitoring capabilities via the Anker app provide real-time and historical energy usage insights, making it an attractive investment for eco-conscious drivers looking to charge e-car with a balcony power station to optimize their renewable energy use. 


Indeed, embracing the initiative to charge E-Car with Mini PV system brings about a paradigm shift towards more sustainable and eco-friendly transportation methods. This approach not only meets the energy demands of electric cars but also presents an efficient and self-sufficient way of charging. By optimizing this process and addressing common issues, we can pave the way towards a more greener and cleaner future of transportation. The journey may come with challenges, but the destination certainly paints a promising picture of environmental responsibility.


Here are some commonly asked questions about the charge E-Car with mini PV system.

How big does a PV system have to be to charge an electric car?

A typical electric car might need a photovoltaic (PV) system of around 2 to 4 kW to provide sufficient charge for daily use, depending on the vehicle's efficiency, the driving distance, and the geographical location. This estimation assumes an average solar panel efficiency and a daily driving distance that aligns with national averages.

How long does it take to charge an E-Auto fully with a 600w mini PV system?

Charging an E-Auto fully with a 600W mini PV system could take over two weeks under optimal conditions, due to limited power output. For a more efficient charging solution, consider using multiple 600W PV systems. This setup will increase the power supply, reducing charging time significantly and providing a more reliable energy source for daily use.

Is 800w mini PV system enough to charge an E-Auto?

An 800W mini PV system, while somewhat more efficient than a 600W system, would still not be sufficient for efficiently charging an electric car on its own, as the system’s output is limited and dependent on sunlight availability. For a more practical charging solution, it is advisable to supplement the 800W system with additional solar panels or a higher capacity system to ensure more consistent and faster charging of your electric vehicle.
