EV Charger Integration with Solar in Roscommon
Electric vehicle ownership is growing rapidly across Ireland — and for those with solar panels already installed, or planning to install them, the opportunity to charge your car from your own free solar energy is significant. Saunderson Solar integrates smart EV chargers with solar systems across Roscommon and the surrounding areas, so every kilometre you drive can be powered by the sun.
Zero Fuel Cost Driving
Why Integrate EV Charging With Solar?
The cost of running a petrol or diesel vehicle in Ireland has never been more exposed as a financial liability. Fuel prices have surged repeatedly in recent years, and for many households and businesses the switch to an electric vehicle has been driven as much by running cost as by environmental principle. But the full financial benefit of EV ownership is only realised when you charge at home — and the full potential of home charging is only unlocked when it's powered by solar energy you generate yourself.
Without solar integration, an EV charger draws entirely from the national grid — and depending on your tariff, evening charging can cost €0.25–€0.35 per kWh or more. With a solar-integrated smart charger, that cost drops dramatically. When the sun is generating more electricity than your home needs — a regular occurrence during Irish summer days and even on many bright winter days — the surplus flows directly into your EV rather than being exported at a low rate. The result is charging that costs a fraction of grid rates, or in many cases nothing at all.
For businesses and farms across Roscommon, the case is equally compelling. Fleet vehicles, company cars, and farm machinery increasingly run on electricity — and a workplace charging infrastructure integrated with an on-site solar system delivers a measurable, ongoing reduction in operating costs that goes straight to the bottom line.
- ✓Fuel and grid electricity prices remain volatile in Ireland
Locking in EV charging from your own solar generation insulates you from future grid price movements — the fuel cost becomes zero for every unit you generate yourself.
- ✓EV ownership is accelerating across Ireland
Government policy, SEAI incentives, and falling vehicle prices are all driving adoption. Installing EV charging infrastructure now puts you ahead of the curve — and the demand curve.
- ✓Solar surplus is best used to charge your vehicle
Without an EV charger, surplus solar power is exported at low Clean Export Guarantee rates. With one, it charges your car instead — maximising the value of every unit your panels generate.
- ✓Reduce your household and business carbon footprint
Charging an EV from renewable solar electricity means near-zero operational emissions — delivering on the environmental commitment many households and businesses are increasingly expected to demonstrate.
- ✓Smart systems manage everything automatically
Modern smart EV chargers communicate directly with your solar inverter — prioritising solar generation for charging without any manual intervention from you.
Key Benefits of EV Charger Integration
Combining an EV charger with your solar system is one of the most practical and financially rewarding upgrades you can make to a property in Roscommon and the surrounding areas.
Lower Charging Costs
Charging from solar power costs a fraction of grid electricity rates. For a household covering 15,000 km per year in an EV, switching to solar-powered charging can save hundreds of euro annually compared to standard grid tariffs.
Smart Energy Optimisation
Smart EV chargers integrated with your solar system automatically prioritise renewable generation for charging. The system balances your home or business energy needs, battery storage (if installed), and EV charging without any manual input.
Faster & Safer Charging
A dedicated home or business EV charger delivers significantly faster charging than a standard 3-pin socket — typically 7–22 kW depending on the unit. Professional installation ensures your charging infrastructure meets all safety and electrical standards.
Reduced Carbon Footprint
An EV charged from grid electricity still carries a carbon cost associated with the generation mix. An EV charged from rooftop solar is as close to zero-emission transport as it's currently possible to achieve — a genuinely green driving solution.
Future-Proof Property Value
EV charging infrastructure is increasingly expected by buyers and tenants across residential and commercial markets. A professionally installed, solar-integrated EV charger adds tangible value to a property and demonstrates forward-thinking energy management.
Energy Independence
Combined with solar panels and battery storage, an integrated EV charger completes an energy ecosystem that minimises what you buy from the grid — for your property, your heating, and your transport. Maximum self-sufficiency from a single smart system.

How Solar EV Charging Works
The integration between your solar panels and EV charger happens automatically in the background — once it's set up correctly, the system manages itself without any input from you.
Solar Panels Generate Electricity
Your solar panels convert sunlight into DC electricity throughout the day. This generation profile peaks around midday and gradually tapers in the afternoon — producing the most power during the hours when many households have their lowest consumption and the most surplus available for EV charging.
Energy Flows Through the Inverter
The solar inverter converts DC electricity into the AC power your property and charger use. Modern hybrid inverters communicate directly with compatible smart EV chargers — sharing real-time generation data so the charger knows exactly how much solar power is available at any moment.
Smart Charger Prioritises Solar Power
When surplus solar generation is available, the smart charger automatically adjusts its charge rate to consume that surplus directly — rather than letting it export at a low rate. This is solar-priority charging mode: your car gets charged first from what you generate, and the grid only makes up any shortfall.
Battery Storage Extends Solar Charging
If you have a battery storage system installed, the energy management system can also draw on stored solar power for EV charging after the panels stop generating — extending the window of solar-powered charging into the evening. The system prioritises domestic loads, then battery charging, then EV charging based on your configured preferences.
Grid Provides Seamless Backup
When solar generation and battery storage are both depleted — typically overnight or during extended dull periods — the EV charger draws from the grid as normal. Smart chargers can be configured to do this during off-peak tariff windows, minimising the grid electricity cost when solar charging isn't possible.
The Result: Near-Zero Fuel Cost for Your Vehicle
A well-integrated solar EV charging setup means a significant proportion of your annual driving distance is covered by electricity you generated yourself — at zero fuel cost. For a typical Irish household driving 15,000 km per year, the annual saving versus grid charging runs to several hundred euro.

Smart Charging & Energy Management
The difference between a standard EV charger and a smart solar-integrated one isn't just convenience — it's financial. A basic charger draws from the grid whenever plugged in, regardless of time or cost. A smart charger communicates with your solar system in real time and makes intelligent decisions about when and how fast to charge, based on what you're generating, what you're consuming, and what you're paying for grid electricity at that moment.
Through a dedicated smartphone app, you have full visibility and control of your charging setup — checking charge status, setting departure targets, and reviewing your energy savings data from wherever you are. The system generates analytics showing how much of your charging has been solar-powered, how much has come from the grid, and what the comparative cost would have been without solar integration.
- Scheduled charging for off-peak grid use
Set your charger to draw from the grid only during low-tariff overnight windows — minimising cost when solar generation isn't available.
- Solar-priority charging mode
The charger automatically adjusts its charge rate to match available solar surplus — consuming what you generate before drawing a single unit from the grid.
- Dynamic load balancing across all circuits
The smart system monitors your total property consumption and adjusts EV charging rate to prevent overloading your supply — particularly important for properties with multiple large loads running simultaneously.
- Remote app monitoring and control
Start, stop, and schedule charging remotely. Check charge level, energy consumed, and solar contribution from your phone at any time.
- Energy analytics and savings insights
Track how much of your EV charging has been solar-powered over the day, week, and month — and see the financial value of that solar contribution compared to grid charging costs.

Safety, Certifications & Compliance
EV charger installation involves significant electrical work — and the qualifications of the people carrying it out matter. Here's what our certifications mean for the safety and compliance of your installation.
RECI Certified Electrical Work
All EV charger installations are carried out by RECI-registered electricians — the Register of Electrical Contractors of Ireland. RECI certification means your installation meets the competence, insurance, and safety standards required for domestic and commercial electrical work in Ireland. You receive a Certificate of Completion for all notifiable electrical works, which is a requirement for home insurance validity and any future property sale.
I.S. 10101 Compliance
Every EV charger installation is carried out to the National Wiring Rules (I.S. 10101) for Electrical Installations (I.S. 10101) — the governing standard for all electrical work in Ireland. This covers the correct sizing and protection of supply cables, earthing arrangements, RCD protection, and consumer unit connection. I.S. 10101 compliance is not optional — it's a legal requirement for any notifiable electrical work, and Saunderson Solar treats it as the baseline standard for every installation we carry out.
Smart System Protection
Modern smart EV chargers include multiple layers of built-in protection — earth fault detection, over-current protection, temperature monitoring, and communication fault handling. We specify chargers with appropriate protection ratings for their installation environment — including IP65 or higher rated units for outdoor and farm installations — and verify all protective functions are operational during commissioning.
Safe Grid Integration
EV chargers connected to properties with solar generation must be integrated carefully to avoid islanding risks, supply interference, and consumer unit overloading. Our installations address all of these requirements as standard — including correct earthing for properties with solar inverters, appropriate RCD selection, and supply capacity verification to ensure your grid connection can safely support both solar generation and EV charging simultaneously.
