If you own an electric vehicle or are thinking about getting one, and you have also been considering solar panels, there is one question worth asking before you do anything else: should you install both at the same time?
The short answer is yes. And the reasons go well beyond simple convenience. Installing an EV charger and solar panels together as a combined system is one of the most financially rewarding home energy decisions an Irish homeowner can make in 2026.
At Vision Solar, we install both solar PV systems and EV chargers across Limerick, Cork, Galway, Kerry, Kilkenny, Laois, and beyond. We speak to homeowners every week who come to us for one and leave with both because once they understand how the two systems work together, the decision becomes straightforward.
This guide explains exactly why, with real numbers and no sales pressure.
How Does Charging an Electric Car With Solar Panels Actually Work?
When your solar PV system generates electricity during daylight hours, that electricity powers whatever is running in your home at that moment lights, appliances, heating. Any surplus that your home is not using in real time is either exported to the national grid or wasted unless you have a way to capture it.
An EV charger connected to your solar system gives that surplus electricity somewhere to go. Instead of being lost to the grid for a minimal export tariff, it flows directly into your electric vehicle’s battery effectively giving you free fuel every sunny day.
This is not a complex technical setup. Modern EV chargers like the Zappi by MyEnergi, which Vision Solar installs as part of our EV charging service, are specifically designed to work with solar PV systems. The Zappi intelligently detects when your panels are generating surplus power and diverts it to charge your car before drawing from the grid.
The result is a home that generates its own electricity, uses that electricity to power daily life, and charges your vehicle for free using whatever is left over all from the same system on your roof.
What Are the Real Financial Benefits of Combining Both?
This is where the numbers get interesting.
Electricity Bill Savings
A well-designed residential solar PV system in Ireland can reduce your household electricity bills by 50% to 80%. For the average Irish home spending €2,000 to €2,500 per year on electricity, that is a saving of €1,000 to €2,000 annually from panels alone.
EV Charging Cost Eliminated
The average Irish EV driver covers approximately 15,000 km per year. Charging that on the public grid or at home using grid electricity costs roughly €600 to €900 per year depending on your tariff.
When you charge your EV using surplus solar electricity, that cost drops to effectively zero during daylight hours. If you add a solar battery storage system, you can store the surplus generated during the day and use it to charge your car in the evening extending free charging further into the night.
Combined Annual Saving
For a typical Limerick or Cork homeowner with solar panels and an EV charger working together:
- Electricity bill saving: €1,000–€2,000 per year
- EV charging saving: €600–€900 per year
- Combined annual saving: €1,600–€2,900 per year
Over the 25-year lifetime of a solar PV system, that is a saving of €40,000–€70,000 from a single combined installation decision.
Why Installing Both at the Same Time Makes Practical Sense
Beyond the financial case, there are very good practical reasons to install your solar PV system and EV charger at the same time rather than doing them separately.
One Survey, One Disruption, One Installation Team
When you install solar panels and an EV charger together, your installer carries out one site survey, designs one integrated system, and completes one installation. This means one set of scaffolding, one electrical inspection, one day or two of work rather than two separate visits weeks or months apart.
Homeowners who install panels first and add a charger later often need to revisit their consumer unit, redo cabling work, and rebook electrical inspections adding cost and time that could have been avoided.
Better System Design From the Start
When Vision Solar designs a combined solar and EV charging system, we size the solar PV installation with your EV charging needs factored in from day one. This means we ensure your panels generate enough surplus to cover meaningful EV charging not just household consumption.
If you install panels first without considering EV charging, you may end up with a system that is undersized for your actual total energy needs. Retrofitting a charger later can also mean your system is not optimised to divert surplus intelligently.
Electrical Work Is Completed Once
Both solar PV systems and EV chargers require electrical work at your consumer unit. Completing this once rather than twice saves labour time and reduces the risk of disruption to your home’s electrical system.

What About Adding a Battery — Should You Do All Three?
Adding solar battery storage to a solar and EV charging combination takes the system to its maximum potential. Here is how it works in practice.
During daylight hours, your panels power your home first. Any surplus charges your battery. If the battery is full and you still have surplus, it charges your EV. In the evening, when the sun goes down, your battery discharges to power your home and continue charging your car.
The result is a home that uses grid electricity for an absolute minimum number of hours per day — and in some cases, households achieve close to full energy independence during the summer months.
Vision Solar installs battery systems from Huawei and Sigenergy, both of which are fully compatible with our solar PV installations and EV chargers. The Sigenergy system in particular is AI-powered, featuring smart energy management that automatically optimises how your solar generation is distributed between household use, battery storage, and EV charging.

FAQ — EV Charger and Solar Panels Together in Ireland
Can I charge my electric car using solar panels in Ireland?
Yes. A solar PV system connected to a compatible EV charger such as the Zappi by MyEnergi allows you to charge your car directly from your solar generation. During daylight hours, surplus electricity that your home is not using is diverted automatically to charge your vehicle instead of being exported to the grid.
What is the best EV charger to use with solar panels in Ireland?
The MyEnergi Zappi is widely regarded as the best solar-compatible EV charger available in Ireland. It is specifically designed to detect surplus solar generation and prioritise it for EV charging before drawing from the grid. Vision Solar installs the Zappi as part of our combined solar and EV charging service.
Do I need a battery to charge my EV with solar panels?
No you can charge your EV with solar panels without a battery. However, adding a solar battery storage system allows you to store surplus solar electricity generated during the day and use it to charge your car in the evening. This significantly increases the amount of free solar charging your vehicle receives.
Is there a grant for EV charger installation in Ireland?
Yes. The SEAI provides a grant of up to €300 toward the cost of a home EV charger installation. This is separate from and in addition to the solar PV grant of €2,400 and the battery storage grant of €600. Vision Solar manages all grant applications on your behalf.
How much does it cost to install solar panels and an EV charger together in Ireland?
A combined solar PV system and EV charger installation for a typical Irish home costs between €8,000 and €14,000 before grants. After the SEAI solar grant, battery grant, and EV charger grant, the net investment is typically between €5,000 and €11,000. Most combined systems achieve full payback within 4 to 7 years.
Should I install my EV charger at the same time as my solar panels?
Yes in almost all cases, installing both at the same time is the better decision. It means one site survey, one installation visit, one set of electrical work, and a system designed from the start to optimise both household solar generation and EV charging. Installing them separately adds cost, disruption, and the risk of a system that is not fully optimised.
