What is home solar EV charging?
Home solar EV charging is an innovative way to power your electric vehicle (EV) using the sun’s energy. By installing solar panels on your roof and connecting them to an electric vehicle charger, you can charge your EV sustainably, reduce your carbon footprint, and save money in the long run. As the demand for clean energy solutions grows, combining home solar power with EV charging is a smart investment for homeowners looking to embrace both sustainability and energy independence.
How Solar EV Charging works
Solar panels - the basics:
Solar panels are devices that convert sunlight into electricity. They are made up of photovoltaic (PV) cells that capture sunlight and convert it into direct current (DC) electricity. This energy can be used to power your home, charge your EV, or be stored for later use with the help of battery systems. The more sunlight your panels absorb, the more electricity they generate, which makes solar energy a free, reliable and renewable source of power. Read more in our blog post here.
Integration Solar with EV charging:
To set up home solar EV charging, the electricity generated by the solar panels is fed into your home’s electrical system, where it powers your appliances and can also charge your EV. You will need a solar inverter, which converts the DC power produced by the solar panels into alternating current (AC) electricity, which is used by most household appliances, including your EV charger.
In most setups, the energy generated during the day can be used directly to charge the EV. If your panels produce more energy than you need, excess energy can either be stored in a battery for use later or sent back to the grid so you're paid for the excess electricity, depending on your system’s configuration. In the summer, we see customers with enough sun to run the household, charge the batteries to full, and still send the excess back to the grid - amazing right!?
Benefits of home solar EV charging
Save Money on Electricity Bills:
One of the most appealing advantages of home solar EV charging is the potential to reduce your energy costs. By generating your own electricity, you can significantly reduce the amount of energy you purchase from the grid. Charging your electric vehicle using solar power, especially if you have excess energy from your solar panels, can drastically cut the costs of fuelling your EV.
Environmentally Friendly:
Charging your electric vehicle with solar power is an eco-friendly choice. Solar energy is a renewable resource, meaning it doesn’t produce harmful emissions. By powering your EV with solar, you are reducing your reliance on fossil fuels, cutting your carbon footprint, and supporting the fight against climate change. This is a great way to take action for a cleaner, greener planet.
Energy Independence:
With home solar EV charging, you gain greater control over your energy consumption. You are no longer entirely dependent on the national grid, which is subject to price fluctuations and outages. Solar energy allows you to produce your own electricity, giving you more energy security and flexibility, particularly when paired with energy storage solutions like batteries.
How to set up home solar EV charging?
Step 1: Install Solar Panels:
The first step in setting up home solar EV charging is installing solar panels. This involves assessing your roof’s suitability for solar panels (size, orientation, and shading) and determining how much energy you’ll need based on your household usage and driving habits. Once this is done, your solar panel installer will place the panels on your roof and connect them to your home’s electrical system.
Step 2: Install an EV Charging Station:
Next, an electric vehicle charging station is installed at your home. There are two main types of EV chargers: Level 1 and Level 2. Level 1 chargers use a standard 120V outlet, which is slower, while Level 2 chargers require a 240V outlet and provide faster charging speeds. The type of charger you choose will depend on your EV’s requirements and how quickly you want it to charge.
Step 3: Battery Storage (Optional):
While it’s not necessary, adding a battery storage system (like a Tesla Powerwall) can enhance your setup. Batteries store excess solar energy generated during the day so it can be used at night or during cloudy days. This means you can continue charging your EV even when your solar panels are not producing electricity.
Step 4: Integration with the Grid:
Your solar panels can be connected to the grid, allowing you to draw energy from it when your solar panels aren’t producing enough electricity. In some cases, you may be able to sell any excess power your solar panels generate back to the grid through net metering, which can earn you credits or payment from your utility company.
