The Ultimate Guide to Installing a Residential EV Charging Station: What Every Georgia Homeowner Needs to Know

As electric vehicles (EVs) continue to gain popularity, more homeowners are looking for efficient ways to charge their vehicles at home. Installing a residential EV charging station can be a game-changer for EV owners, offering convenience and long-term cost savings. At Roswell Solar, we understand that investing in EV technology is a step toward a greener future, and we’re here to guide you through the process.

Whether you’re new to EVs or a seasoned owner looking to upgrade your setup, this comprehensive guide will walk you through everything you need to know about installing a residential EV charging station in Georgia. From understanding the types of chargers available to grasping local installation requirements, we’ll help you make the best decision for your home and lifestyle.


1. Why Install a Home EV Charging Station?

Before diving into the technical aspects, it’s essential to understand why having a dedicated charging station at home is beneficial.

  • Convenience: Charging at home means you can plug in your vehicle overnight and have it ready to go in the morning without needing to stop at a public charging station.
  • Cost Efficiency: Charging your EV at home is often cheaper than using public charging stations, especially if you install solar panels and harness the power of renewable energy.
  • Increased Property Value: As EVs become more popular, homes with pre-installed charging stations are becoming more attractive to buyers.
  • Energy Independence: With solar energy from Roswell Solar powering your EV, you can dramatically reduce or eliminate your reliance on the grid for your transportation needs.

2. Types of EV Chargers

There are three main levels of EV chargers available for residential use, each with its own advantages and limitations.

Level 1 Chargers

  • Power Output: 120 volts
  • Charging Speed: 3-5 miles of range per hour of charging
  • Best For: Occasional EV drivers or plug-in hybrid owners
  • Installation: Plugged into a standard wall outlet
  • Pros: No special equipment or installation costs
  • Cons: Slow charging times

Level 1 chargers are the simplest and most cost-effective option since they use a standard household outlet. However, they can take up to 24 hours to fully charge an EV with a large battery, making them less ideal for daily drivers.

Level 2 Chargers

  • Power Output: 240 volts
  • Charging Speed: 20-50 miles of range per hour of charging
  • Best For Daily EV drivers who need quicker charging
  • Installation: Requires a dedicated 240-volt outlet, similar to an electric dryer
  • Pros: Faster charging times and can be integrated with solar energy systems
  • Cons: Requires professional installation and costs more upfront

Most EV owners opt for Level 2 chargers because they offer a significant improvement in charging speed while still being affordable. These chargers typically need professional installation, but the convenience they offer makes them worth the investment.

 Level 3 Chargers (DC Fast Chargers)

  • Power Output: 400-900 volts
  • Charging Speed: 200-1200 miles of range per hour of charging
  • Best For Commercial or public use, not generally recommended for residential installations
  • Installation: Requires special equipment and usually a three-phase electrical supply, typically not available in homes
  • Pros: Ultra-fast charging
  • Cons: Extremely expensive, not suited for residential use

While Level 3 chargers provide the fastest charging times, they are rarely installed in residential settings due to their high cost and complex installation requirements. These chargers are more commonly found in commercial areas or along highways for long-distance EV travel.


3. How to Choose the Right EV Charger for Your Home

Selecting the right charger depends on your driving habits, home setup, and budget. Here are key factors to consider when making your decision:

Daily Driving Habits

If you drive less than 30 miles a day and have time to charge overnight, a Level 1 charger may suffice. However, for most EV owners, a Level 2 charger offers a better balance of convenience and performance, especially if you drive more frequently or longer distances.

Electric Vehicle Specifications 

Check the charging capacity of your EV. Some vehicles can only accept a certain maximum charging speed. If your car can’t take advantage of a Level 2 charger’s full output, you might not need the fastest charger available.

Solar Integration 

If you’re considering going solar with Roswell Solar, a Level 2 charger is ideal for maximizing your energy efficiency. Solar panels can power your home during the day while charging your EV simultaneously, allowing you to significantly cut down on energy costs and reduce your carbon footprint.

Budget 

A Level 1 charger comes at no extra cost if you already have an available outlet. Level 2 chargers generally cost between $500 and $900, excluding installation. While this is a significant investment, the increased convenience and faster charging times make it worthwhile for most daily EV drivers.

Future-Proofing 

If you’re planning on keeping your EV for several years or even upgrading to a newer model, it’s wise to choose a charging station that can accommodate your future needs. Opt for a Level 2 charger with adjustable output settings to ensure compatibility with different EVs.

4. Installation Requirements

Installing an EV charging station involves more than just plugging in a charger. Here’s what you need to know to get your home ready.

Electrical Panel Assessment 

First, you’ll need to determine whether your home’s electrical system can handle the additional load of an EV charger. For a Level 2 charger, this often means installing a dedicated circuit. Homes with older electrical systems may require an upgrade to ensure safe and reliable operation.

A licensed electrician will typically assess your home’s electrical panel to see if it has enough capacity. If upgrades are needed, this could add to your overall costs.

Permits and Local Regulations 

In Georgia, homeowners may need permits to install a Level 2 charging station, depending on local regulations. At Roswell Solar, we help homeowners navigate the permitting process, ensuring all installations comply with local building codes and utility requirements.

Be aware that different cities and counties in Georgia may have specific regulations regarding EV charging stations. It’s always a good idea to check local codes or consult with professionals who are familiar with Georgia’s specific requirements.

Location of the Charging Station 

Where you install the charger in your home is critical. The ideal spot is usually in the garage, close to your EV’s parking spot. You’ll also need to consider the length of the charging cable and whether you’ll need to run new wiring through walls or ceilings to reach your desired location.

For outdoor installations, be sure to invest in weatherproofing to protect your charging station from the elements.

Professional Installation 

While it’s possible to DIY some parts of a Level 1 charger setup, Level 2 chargers generally require professional installation. A certified electrician or a solar professional from Roswell Solar will ensure your installation is safe, efficient, and up to code. This is particularly important if you’re tying the system into a solar energy setup.


5. How Solar Energy Complements Your EV Charging Station

At Roswell Solar, we specialize in helping homeowners power their lives with renewable energy. Combining an EV charging station with solar panels is one of the best ways to reduce your overall energy costs and environmental impact.

Here’s how it works:

  • Solar Panels Generate Energy: Your solar panels convert sunlight into electricity, which can power your home, including your EV charger.
  • Excess Energy is Stored or Sold: If you have a solar battery, excess energy can be stored for later use. If you don’t have a battery, you may be able to sell excess electricity back to the grid through net metering.
  • Charge Your EV with Renewable Energy: By using solar power to charge your EV, you can drive with zero emissions, reducing both your carbon footprint and your dependence on fossil fuels.

In Georgia, the state offers several incentives for homeowners who install solar panels, including tax credits and net metering programs, making it an even more attractive option for EV owners.


6. Cost Breakdown of Installing an EV Charging Station

Here’s a general cost estimate for installing an EV charging station in Georgia:

  • Level 1 Charger: $0 if you use an existing outlet
  • Level 2 Charger: $500 – $900 for the equipment, plus $300 – $1,500 for installation, depending on the complexity
  • Electrical Upgrades: $1500 – $4000, depending on your home’s current electrical system
  • Permits: $50 – $300, depending on local regulations

For level 2 chargers you can claim a 30% federal tax credit up to a maximum of $1000. Some utility companies like Georgia Power also offer rebates of up to $200 for the installation of residential level 2 chargers. At Roswell Sola, we can help you navigate the various incentives available to you to maximize your savings.

If you’re also installing solar panels, the typical system cost can range from $10,000 to $30,000, depending on the size of your system and energy needs. However, with tax credits and energy savings, your solar investment can pay for itself over time.

The 30% federal tax credit applies to the total solar system cost and installation including any electrical improvements bundled with the installation of solar panels.  Performing any necessary electrical work, battery installation, etc with Solar can be a cost-effective way to complete desirable upgrades and improve the value of your home. Depending on how much sunlight your property receives, systems can pay for themselves in as little as 5-7 years and continue generating savings for decades to come.
