If you’ve got solar panels on your home and you’re thinking about buying an electric vehicle, you may be wondering whether you can charge your car using the electricity generated by your solar panels.
The good news is that you can.
Combining solar panels with a home EV charger can be an excellent way to make better use of renewable energy generated at your property. Instead of relying entirely on electricity from the grid to charge your electric vehicle, you can potentially use some of the electricity generated by your own solar PV system.
For homeowners across Maidstone, Medway, Kent and the wider South East, solar panels and EV charging are becoming an increasingly popular combination.
TH Electrical provides solar PV, battery storage and home EV charger installation, helping homeowners create more efficient and flexible home energy systems.
If you’re considering installing an EV charger at home, upgrading your solar panels or combining the two, speak to TH Electrical on 01622 910021 or email info@th-electrical.co.uk.
Can Solar Panels Charge an Electric Car?
Yes, solar panels can be used to generate electricity for charging an electric vehicle.
Your solar PV system generates electricity from daylight. That electricity can be used by appliances and electrical equipment within your home, including a compatible EV charging point.
If your solar panels are generating more electricity than your home is using at that moment, a suitable EV charging system can potentially use some of that surplus electricity to charge your car.
This means your electric vehicle can effectively be powered using renewable electricity generated at your own home.
The exact way your system operates will depend on the solar PV installation, EV charger, vehicle and energy management equipment you have installed.
Why Combine Solar Panels With an EV Charger?
There are several reasons why homeowners are choosing to combine solar PV and electric vehicle charging.
Firstly, it allows you to make greater use of the electricity your solar panels generate.
Secondly, charging your car with your own solar electricity can potentially reduce your reliance on grid electricity.
And thirdly, it brings two renewable-energy technologies together in one home energy strategy.
If you’ve already invested in solar panels, an EV charger can provide another way to use the electricity they generate.
If you’re considering both technologies for the first time, having them assessed together can help you plan a system that works with your home’s electricity requirements.
What Happens When Your Solar Panels Produce More Electricity Than Your Home Needs?
This is an important part of understanding how solar EV charging works.
Imagine your solar panels are generating electricity during the day. Your home is using some of that electricity to power lights, appliances and other equipment.
If your panels are generating more electricity than your home requires, the surplus electricity has to go somewhere.
Depending on your setup, surplus electricity could potentially be exported to the grid, stored in a home battery or used to charge your electric vehicle.
With a suitable solar-aware EV charging system, your vehicle can potentially make use of surplus solar generation.
This can help increase the amount of electricity you consume within your own property rather than exporting all of the surplus.
What If My Car Is Not at Home During the Day?
This is one of the biggest considerations when combining solar panels and EV charging.
Solar PV generates the most electricity during daylight hours, but many people take their cars to work during the day.
If your vehicle isn’t at home when your solar panels are generating electricity, you won’t be able to use those solar-generated kilowatt-hours to charge the car at that time.
However, this doesn’t mean solar and EV charging aren’t worthwhile together.
A smart EV charger can allow you to schedule charging at particular times, while a home battery may allow you to store surplus solar electricity for later use.
Your electricity tariff may also offer cheaper overnight charging periods.
The best setup depends on your lifestyle, electricity usage and when your vehicle is normally parked at home.
Can You Charge Your EV at Night With Solar Power?
Not directly from solar panels, because your panels aren’t generating electricity from sunlight at night.
However, if your home has a battery storage system, surplus electricity generated by your solar panels during the day can potentially be stored and used later.
Alternatively, you can charge your EV from the grid at night, potentially taking advantage of a suitable time-of-use electricity tariff.
This is why an integrated approach to solar panels, battery storage and EV charging can be useful.
What Is a Solar-Compatible EV Charger?
Some EV chargers have features that allow them to work alongside solar PV systems.
Depending on the charger and system design, the charger can monitor electricity generation and household consumption.
This can allow it to adjust the amount of electricity being sent to your vehicle.
For example, if your solar panels are producing surplus electricity, a compatible charger may be able to use that surplus to charge your vehicle.
The exact functionality depends on the charger and installation, so it’s important to choose equipment that is compatible with your requirements.
Is Charging an EV From Solar Panels Cheaper?
It can be.
Electricity generated by your solar panels is electricity you have produced yourself, so using it to charge your vehicle can reduce the amount of electricity you need to purchase from the grid.
However, there are several factors to consider when looking at the overall financial benefit.
These include your solar generation, electricity tariff, EV battery size, driving habits, charging times and the proportion of solar electricity that you can use directly.
There is also the initial cost of installing the solar PV system and EV charger.
For homeowners who already have solar panels, adding an EV charger can be a particularly attractive option because the solar system is already generating electricity.
Should You Install Solar Panels and an EV Charger Together?
If you’re planning to buy an electric vehicle and don’t already have solar panels, it can be worth considering both systems together.
The advantage of doing this is that your installer can look at your home’s overall electrical requirements rather than treating each installation separately.
Your future electricity consumption may be significantly higher once you have an EV.
Charging an electric car can add a substantial new electrical load to your property, depending on how much you drive and how frequently you charge.
Considering solar generation, EV charging and battery storage together can therefore help you plan for your future energy requirements.
Can You Add an EV Charger to an Existing Solar System?
Yes, in many cases.
If you already have solar panels installed and have recently purchased an electric vehicle, an EV charger can potentially be added to your existing electrical installation.
Before installation, the electrical system should be assessed to determine whether it is suitable for the additional load.
The existing solar PV system should also be considered if you want to make use of surplus solar generation.
At TH Electrical, we can discuss your existing solar installation and your EV charging requirements to help determine what options may be suitable.
What About Battery Storage?
Battery storage can make the combination of solar panels and an EV charger even more flexible.
During the day, your solar panels may generate more electricity than your home immediately requires.
A battery can potentially store some of this surplus electricity.
Later, when the sun is no longer shining, stored electricity can be used within your home or potentially towards EV charging, depending on the system design.
This can help you make greater use of your own renewable electricity.
Whether a battery is worthwhile will depend on your electricity consumption, solar generation, EV usage and energy tariff.
