Introduction: A Cleaner Way to Charge Your EV

Electric cars (EVs) gain popularity with each year. They are environment friendlier and cut on fuel consumption. But have you ever wondered what you do with your EV to charge it?

Using grid electricity,The majority of citizens recharge their EVs. Yet frequently this electricity is produced by coal or other fossil ingredients. This implies that your clean car is still doing some forms of pollution to the surroundings.

Then the bright idea of solar EV charger is here. These are chargers that harnessed the power of the sun to do some charging of your electric car. It is just like driving your car on the sunshine!

In this article, we are going to talk about solar EV chargers in an uncomplicated way, what are they, how are they beneficial, what is their price, and is it a good idea to use it by you.

Solar EV Charger

What is a Solar EV Charger?

A solar EV charger is an electric vehicle that uses solar energy (sunlight) as it is the energy source.

As opposed to relying entirely on the grid energy supply, a solar charger is powered by solar panels. They mount these panels on a rooftop, garage, carport, or on land that is open. Solar energy is then employed to recharge your automobile.

Types of Solar EV Chargers

  1. Grid-Tied Solar EV Charger

  • Linked to the electricity grid.
  • Solar is leaned on and the grid is switched to when there is less solar (such as night time, or on cloudy days).
  1. Off-Grid Solar EV Charger

  • It is not linked to the grid.
  • Requires a battery system to store solar energy to use in the nights or rainy weather.
  1. Hybrid Solar EV Charger

  • Combination of both grid-tied and off-grid. 
  • Prefers solar over battery & over the grid at last.

How Does a Solar EV Charger Work?

Here’s a simple step-by-step explanation:

  • Solar panels have the ability to convert sunlight into electricity (DC).
  • The inverter produces the DC current into AC that can be utilized by EVs.
  • This power is delivered to your EV battery by sending them by the charger unit.
  • Should there be excess power, then it could be stored in a battery or out to the grid.

Benefits of Using a Solar EV Charger

  1. Eco-Friendly Charging

You are even using the sun, which is a clean, and renewable source of energy to charge your car. Carbon footprint is lowered, close to zero.

  1. Saves Money in the Long Run

While the installation cost is high at the beginning, you save a lot on electricity bills over time. Sunlight is free!

  1. Energy Independence

No need to rely on the power grid or worry about rising electricity prices.

  1. Government Subsidies

subsidies, tax benefits, and discounts for solar systems and EVs are offered by many countries.

  1. Increase in Property Value

Most valuable in the market are homes with solar panels and EV chargers .

What Do You Need to Set Up a Solar EV Charger?

During installation of a solar EV charging system at home or company, the following will be required:

  • The amount of solar panels you need is based on your battery size and frequency of driving (number of panels)
  • Solar inverter (to invert DC to AC)
  • Level 1 or Level 2 EV charging station
  • Mounting ( roof or ground mounts )
  • Option battery storage (can be useful to off-grid systems)
  • Installation service (technicians certified)

Amount of Solar Panel Needed to Charge an EV?

This depends on the size of your EV battery and how much you drive daily.

Let’s take an example:

  • You drive 50 km per day.
  • Your EV consumes around 0.2 kWh/km.
  • That’s 10 kWh per day.
  • 300 watts is provided by a standard solar panel(0.3 kW) per hour.
  • So, you need around 10–12 panels to produce 10 kWh/day.

But the number may change based on sunlight in your area, panel efficiency, and battery size.

Cost of Installing a Solar EV Charger

Here’s a rough cost estimate for a home solar EV charger in India or similar countries:

Component ApproximateCost(INR) 
Solarpanels(2 – 4 kW) ₹1,00,000–₹2,00,000  
Inverter ₹20,000–₹50,000      
EVchargingunit ₹40,000–₹70,000      
Mounting&wiring ₹10,000–₹20,000      
Battery(Optional) ₹60,000–₹1,00,000    
TotalEstimate ₹2,00,000–₹4,50,000

 Note: Prices vary depending on brand, location, and type of setup.

Charging Speed of Solar EV Chargers

 Level 1 Charger (Slow Charging)

  • Uses a normal home socket (AC)
  • Takes 8 to 12 hours for full charge

 Level 2 Charger (Fast Charging)

  • Special AC charging station
  • Takes 4 to 6 hours for full charge

Solar EV chargers are mostly Level 2, which is good for daily use at home or work.

Solar EV Chargers at Workplaces or Commercial Spots

More companies are now installing solar EV charging stations at:

  • Office buildings
  • Shopping malls
  • Schools and colleges
  • Hotels and resorts
  • Parking lots

EV users are helped to be attracted, and it is shown that the environment is cared for by the business. Free charging as a service to customers is offered by some of them.

Real-Life Examples of Solar EV Chargers

  1. Tata Power EZ Charge

Tata Power has set up solar-powered EV chargers in Mumbai and Delhi. They are easy to find using a mobile app.

  1. Delhi Metro

Some Delhi Metro stations now have solar panels and EV chargers, encouraging green travel.

  1. Bangalore Tech Parks

Many tech companies in Bengaluru have installed rooftop solar chargers for employees’ EVs.

Challenges of Solar EV Chargers

While they are great, there are a few challenges:

  1. High Initial Cost

Even though you save money later, the setup cost is still high.

  1. Sunlight Dependence

Solar chargers work best in sunny areas. In rainy or snowy places, output drops.

  1. Space Needed

You need a good amount of roof or land space to install solar panels.

  1. Battery Cost (for Off-Grid)

If you want full independence from the grid, you need a battery system, which is expensive.

Is a Solar EV Charger Right for You?

Ask yourself these questions:

  • Do you get good sunlight where you live?
  • Do you drive your EV regularly?
  • Can you invest in the initial cost?
  • Do you want to save on electricity bills?
  • Do you care about the environment?

If you answered yes to most, then a solar EV charger is a smart investment for you.
