As electric vehicles (EVs) become more prevalent in Australia, so do the options for charging them. Many automakers now offer EVs at more affordable prices, and the renewable energy sector is proliferating, making it easier than ever to charge your EV using solar panels. Transparent Solar Solutions (TSS) is leading this sustainable movement.
Why Charge Your EV with Solar Panels?
According to recent industry reports, electric vehicle sales in 2022 hit a record high, capturing a significant portion of the auto market. EVs not only help reduce your carbon footprint compared to petrol-powered cars, but they also save you money on fuel. Most EV owners prefer to charge at home or work, relying on public chargers only when travelling long distances.
Here are some things to consider:
- Energy Requirements: How much energy does an EV need to fully charge?
- Efficiency and Cost: Is there an economical and efficient way to power your EV?
Energy Consumption and Calculation
The energy efficiency of EVs is typically measured in kilowatt-hours per 100 kilometres (kWh/100km). While this varies across different makes and models, the average EV in Australia might use around 18-25 kWh per 100 km. This translates into approximately 0.18 to 0.25 kWh per kilometre driven.
For home charging, there are two main options:
- Level 1 Charger: Also known as a trickle charger, suitable for overnight charging.
- Level 2 Charger: Faster and more efficient, ideal for those with limited time.
Solar Charging Setups
Integrating solar panels with an EV charger is straightforward. A typical solar EV setup includes rooftop solar panels, inverters, a current transformer (CT) meter, and a Level 2 EV charger. TSS’s innovative solar systems enable you to create an integrated solar EV charging station. With our systems, you can monitor and control energy consumption via an app, ensuring your EV is primarily or exclusively powered by solar energy.
How Much Solar Capacity Is Needed?
On average, an Australian household might need about 4-6 kW of solar capacity to meet the annual energy requirements of an EV, which equates to approximately 18-25 kWh per 100 km of travel. This typically means installing around 10-15 solar panels, depending on their wattage. Use Enphase’s solar calculator for a personalised estimate based on your driving habits and specific vehicle.
Cost-Effectiveness
Charging your EV using solar power at home is environmentally friendly and cost-effective. The annual cost of charging an EV with solar energy can be significantly lower than using grid power or public charging stations, potentially saving you hundreds of dollars each year.
Enhancing Independence with Battery Storage
A solar system combined with battery storage offers greater independence from the grid. Battery storage ensures that you can access stored solar power during blackouts or peak demand periods, allowing for better control over your energy use. Bi-directional chargers can transform your EV into a power source for your home through vehicle-to-home (V2H) and vehicle-to-grid (V2G) systems.
