EV Chargers and Solar: The Perfect Match for NZ Homes

Electric vehicles (EVs) are rapidly gaining popularity across New Zealand. Offering lower running costs, reduced emissions, and backed by government support, EVs are becoming an increasingly common sight on the nation’s roads. But the next step toward truly sustainable driving is combining EV chargers with solar power.

Pairing solar energy with EV charging not only makes powering your car more affordable but also ensures that the energy you use is clean, renewable, and future-focused. For households across New Zealand, it’s the ultimate way to maximise both cost savings and environmental impact.

Why Solar and EV Chargers Work So Well Together?

When you plug your EV into the grid, the electricity you use may come from a mix of renewable and non-renewable sources. By integrating solar panels with a home EV charger, you’re tapping directly into free, renewable energy generated on your roof.

Here’s why they’re a perfect match:

• Cost Savings – Once your solar system is installed, sunlight is free. Charging your EV during the day reduces or eliminates reliance on paid grid electricity for your vehicle.
• Lower Carbon Footprint – Solar-powered EV charging ensures you’re driving is powered by clean, renewable energy.
• Energy Independence – Instead of depending on rising electricity prices, you take control of your household energy use.
• Increased Efficiency – In the future, EVs could act as a storage extension for your solar system, especially as vehicle-to-home (V2H) technology advances.

How Much Can You Save with Solar EV Charging?

The average Kiwi household spends thousands annually on fuel. Switching to an EV already delivers significant savings, but when paired with solar, the costs drop even further.

For example:

• Charging an EV from the grid may cost around NZD $3–$4 per 100km.
• With solar, charging during daylight hours can be essentially free, depending on your system size and household energy use.

Over time, this adds up to thousands in savings while also shielding you from future price hikes in electricity or petrol.

The Energy Efficiency and Conservation Authority (EECA) notes that combining renewable energy with EV chargers is one of the most effective ways to reduce household carbon emissions. It’s not just about saving money, it’s about making an investment in your family’s sustainable future.

Smarter Energy Use with Solar + EV Chargers

Modern EV chargers are designed to work intelligently with solar power systems. Many units can be programmed to prioritise charging when solar output is highest, making use of the clean energy generated during the day.

Some smart chargers also allow you to:

• Monitor energy use in real time.
• Adjust charging speed to match available solar supply.
• Schedule charging during off-peak times for additional grid savings.

This flexibility ensures you get the most from your solar investment while ensuring your EV is ready whenever you need it.

The Environmental Impact of Solar EV Charging

Transport is one of the largest contributors to New Zealand’s greenhouse gas emissions. By driving an EV, you’re already cutting down your personal emissions, but pairing it with solar takes your impact to the next level.

According to the Ministry of Transport, electric vehicles are central to New Zealand’s decarbonisation goals, and renewable energy is key to unlocking their full potential. With over 80% of New Zealand’s electricity already generated from renewable sources, adding rooftop solar means you’re going above and beyond, making your household even more sustainable.

Key Considerations Before Installing Solar EV Chargers

If you’re thinking of pairing solar with EV charging, here are some important points to consider:

• System Size – Larger solar systems allow for more charging capacity. Work with an installer to size your system based on EV use and household energy needs.
• Smart Chargers – Choose an EV charger that integrates with solar to maximise efficiency.
• Battery Storage – Adding a home battery lets you store excess solar energy for night-time charging.

Why Now is the Right Time to Act?

Electric vehicle ownership in New Zealand is growing rapidly, and government policy continues to encourage greener choices. Installing solar panels and an EV charger together positions your home for long-term sustainability and savings.

With rising electricity costs and growing environmental awareness, there has never been a better time to combine solar energy with EV charging at home.
