What Are Solar EV Chargers?
A solar EV charger is a device that allows you to charge your electric vehicle using electricity generated from solar panels installed at your home. Unlike traditional EV chargers that draw power from the grid, solar EV chargers prioritise using renewable energy, reducing electricity bills and carbon emissions.
How Solar EV Chargers Work at Home
Solar EV chargers are designed to connect your home solar system with your EV’s battery. During the day, your solar panels produce electricity that can either power household appliances, feed excess energy into the grid, or charge your EV. When the sun isn’t shining, your charger may pull energy from the grid or a home battery if one is installed.
This setup ensures that your vehicle can be charged efficiently while maximising the use of free solar energy, reducing your dependence on costly electricity from the grid.
Why Solar EV Charging Is Growing in Perth
Several factors are driving the rapid adoption of solar EV charging in Perth:
- High Sunshine Levels: Perth enjoys one of the highest average annual sunshine hours in Australia, making solar energy highly reliable.
- Rising Electricity Costs: With increasing energy tariffs, homeowners are motivated to generate their own electricity to reduce bills.
- EV Adoption: More Perth residents are switching to electric vehicles, increasing the demand for convenient and affordable home charging solutions.
Solar EV chargers combine these factors into a practical, environmentally friendly solution that makes sense financially and ecologically.
Is Your Home Ready for a Solar EV Charger?
Before installing a solar EV charger, it is important to understand whether your home can safely support the additional electrical demand. While many Perth homes are suitable for EV charging, some may require minor upgrades or planning adjustments to ensure reliable and safe operation. Assessing readiness early helps avoid installation delays and unexpected costs.
Electrical Capacity and Safety Considerations
Your home electrical system is the foundation of a safe solar EV charging setup. The switchboard is one of the first components that installers evaluate. Older homes may have switchboards that were not designed to handle high-powered appliances like EV chargers. In such cases, an upgrade may be required to meet current safety standards and allow for consistent charging performance.
Wiring quality and capacity are equally important. EV chargers draw a continuous electrical load, which means the wiring must be capable of handling sustained current without overheating. Load capacity is also reviewed to ensure your household appliances, solar system, and EV charger can operate together without tripping circuits or stressing the system. A professional assessment helps identify whether load management or safety devices are needed to balance power usage effectively.
Preparing Your Home for EV Charging Installation
Beyond electrical capacity, practical installation factors also play a major role in readiness. The location where you park your vehicle influences charger placement, cabling distance, and overall installation cost. Garages, carports, and dedicated parking areas each require different mounting and cable routing approaches.
Cabling paths should be planned carefully to maintain a clean appearance and comply with safety regulations. Installers often look for routes that minimise drilling and avoid exposure to weather or physical damage. Thinking ahead is also essential. Many homeowners plan for future needs such as a second electric vehicle, a larger solar system, or battery storage. Preparing for these possibilities now can save time and money later.

Different Ways Solar EV Chargers Can Be Set Up at Home
Solar EV chargers can be configured in several ways depending on how your home uses energy and when your vehicle is typically charged. Understanding these setup options helps homeowners in Perth choose a system that delivers the best balance of convenience, savings, and future flexibility.
Common Solar EV Charging Configurations
The most common setup is a grid-connected solar EV charging system. In this configuration, the EV charger prioritises electricity generated by your solar panels during the day. When solar production is not enough, such as in the evening or on cloudy days, the system automatically draws power from the grid. This setup is popular because it is simple, reliable, and compatible with most existing solar installations.
Another option is smart solar diversion charging. This setup uses intelligent controls to detect excess solar energy that would otherwise be exported to the grid. Instead of sending surplus power away, the charger directs it to your electric vehicle. This approach increases solar self-consumption and is ideal for homeowners who want to maximise the value of their solar system without adding batteries.
Battery-supported charging is the most advanced configuration. In this setup, solar energy is stored in a home battery during the day and used to charge the EV later, often at night. This allows for greater independence from the grid and provides consistent charging even when the sun is not shining. While this option involves higher upfront costs, it offers long-term flexibility and energy security.
Choosing a Setup That Fits Your Lifestyle
Your daily routine plays a major role in determining the best solar EV charging setup. Homeowners who work from home or are often present during daylight hours can benefit greatly from daytime solar charging, as their vehicles can charge directly from solar production.
Households where the EV is used mainly for commuting may prefer systems that support evening or overnight charging, especially when paired with battery storage. Planning for future needs is also important. If you expect to add another electric vehicle, expand your solar system, or install a home battery later, choosing a flexible charging setup now can prevent costly upgrades down the line.
The right configuration is not just about current usage but about aligning your energy system with how your household will evolve over time.
