Solar Charging for EV: Power Up Your Ride with the Sun

Homeowners up and down the country (and across the world) are moving to Electrical Vehicles, but one challenge to deal with is charging them – especially when you want to do it at home and see your energy bills multiply! There is a better way to power up your electric ride than connecting it to the grid though – solar charging. Yep, you read that right. You can harness the sun’s energy to fuel your car and say goodbye to those pesky electricity bills.

What Is Solar EV Charging and How Does It Work?

Are you one of the growing number of people looking for ways to reduce your reliance on fossil fuels? Have you considered using solar energy to charge your electric vehicle? Not only is this a more sustainable option, but it can also save you money in the long run. Green and cheap, just the way we like it.

How Solar Panels Generate Electricity

Solar panels generate electricity by converting sunlight into direct current (DC) electricity. The solar cells in the panels are made of semiconductor materials, typically silicon, that absorb photons from sunlight. When the photons strike the solar cells, they knock electrons loose from their atoms, allowing them to flow through the material to produce electricity.

How Solar Energy Powers EV Chargers

You can charge your EV with solar panels if you’ve got the right set-up – you’ll need to invest in a solar PV system and a solar compatible EV charger. You can also invest in a solar battery storage system if you’d like to charge overnight.

Benefits of Solar EV Charging

Another major benefit of combining home solar with electric car ownership is further reducing carbon emissions. Moving from a car with an internal combustion engine fueled by gas to one with an electric motor is already a huge improvement. If you’re charging that EV with electricity from the grid, chances are you’re still relying on fossil fuels. By using solar to power your electric vehicle, you become less reliant on nonrenewable energy and shrink your carbon footprint even more.

How Many Solar Panels Are Needed to Charge an Electric Car?

You can fully charge an electric car with solar energy. You’ll need to put up a domestic Solar Photovoltaic System (Solar PV), along with the solar charger for the car battery. Solar panels and electric vehicles are a match made in heaven, on your roof.

Factors Affecting Solar Panel Requirements

When you own an electric vehicle any standard 120-volt outlet can be the source of a few more miles. This may work in a pinch, and if you have time to burn, but it’s just not efficient. A 120-volt outlet will only add about 4 miles per hour and take a full 8-16 hours to fully charge.

Calculating Solar Panel Needs Based on EV Battery Capacity

Let’s assume you haven’t installed a solar energy system yet, and during the process of working with an installer, you let them know you’re planning on charging an EV with your solar system: they’ll factor that into the size of your solar system so it can generate enough electricity to power your EV.

Solar PV systems generate electricity from the sun, which can then be used to charge an electric car or anything else in your household. The average domestic solar PV system can generate one to four kilowatts of power (kWp). This is enough to fully charge an electric car with a battery capacity of 40 kWh in just over eight hours.

Real-World Examples of Solar Panel Setups for EV Charging

Of course, the amount of solar energy available to charge an electric car will vary depending on the time of year and the weather conditions. In winter, when there is less daylight and more cloud cover, you may need to supplement your solar PV system with power from the grid. But solar energy is a great way to charge an electric car in a really sustainable way, even if you only partly charge the car.

Generally, larger batteries need more panels. So if you’re looking to install a solar PV system specifically for charging your car, it’s best to speak to a professional about the right size and type of system for your needs. On average, a solar panel system with around 8-12 panels can power an electric vehicle – but please check this with whoever is installing your solar panels.

Types of Solar EV Chargers and Their Features

Yes, you can use a regular EV charger with solar panel charging but you’ll need a PV inverter unit that converts solar energy into electricity in order to start charging your EV with solar panels. Most installations will have an inverter as standard but it’s important to check. The inverter is what changes the current from DC to AC so you can use electricity from the panels to power your home and devices. EV home chargers use AC.

Smart Solar EV Chargers

Thankfully, the newest PV equipment automates the charge-scheduling question for you.

Some EV chargers already have this technology in the box so you can start charging straight away, but again, it’s important to check.

Integrated Solar EV Chargers

Secondly, solar panels generate power during daylight hours (when we get more sun), but most people charge their electric car overnight while they’re sleeping. So, if you want to charge your EV using that solar power at night, you’ll need a battery storage system that stores the energy generated throughout the day and then releases it when you need it – such as at night when charging your EV.

Installing Solar Panels for EV Charging: A Step-by-Step Guide

Let’s assume you haven’t installed a solar energy system yet, and during the process of working with an installer, you let them know you’re planning on charging an EV with your solar system: they’ll factor that into the size of your solar system so it can generate enough electricity to power your EV.

Adding more panels to your existing solar system or to one that you’re planning is one way to power all your home’s energy needs, including your EV. But it isn’t necessarily the only way to charge your EV. You can also build a stand-alone off-grid system that’s dedicated to just your car.
