Factors to consider: A sun-powered puzzle

Unfortunately, there’s no one-size-fits-all answer. The number of solar panels you’ll need depends on several factors, including:

  • Your car’s energy consumption: EVs have varying battery capacities and energy efficiency. A city car like a Hyundai Kona Electric will need fewer panels than a lower-efficiency SUV like a Tesla Model X.
  • Your driving habits: How much do you drive each day? If you’re a daily commuter, you’ll need more panels than someone who only drives on weekends.
  • Sunshine hours in your location: Australia’s diverse landscape means sunshine hours vary considerably across the country. Places like Darwin bask in over 7 hours of sunlight daily, while Melbourne averages around 5 hours.
  • Your solar panel system’s efficiency: Panels come in various wattages, with higher wattages generating more power per panel.

Solar power to EV charger: Let’s do the maths!

To give you a rough idea, let’s assume you drive an average Australian distance of 15,000 km per year in a moderately efficient EV with a 50 kWh battery. You live in a sunny city like Brisbane with about 5 hours of daily sunlight.

Here’s a breakdown:

  • Daily energy consumption: Assuming an average consumption of 15 kWh/100km, you’ll use 22.5 kWh daily (150 km/day x 15 kWh/100km).
  • Solar panel output: A typical 6.6 kW solar panel system in Brisbane generates around 4 kWh per day per kW capacity. You’ll need a system size of roughly 6 kW (22.5 kWh / 4 kWh/kW) to meet your daily needs.
  • Number of panels: Depending on the panel wattage (say 370 W), you’d need around 16 panels (6 kW / 0.37 kW/panel).

But wait, there’s more!

Remember, this is just a rough estimate. Your actual needs may vary. Here are some additional factors to consider:

  • Charging efficiency: Not all the energy from your solar panels will be transferred to your car’s battery. Expect a loss of around 10-15% during charging.
  • Solar EV charger: A dedicated solar EV charger can maximise efficiency and minimise energy loss.
  • Battery storage: Consider adding a home battery system to store excess solar energy for charging your car at night or on cloudy days.
