The Problem: Rising Energy Costs and Grid Dependency

Impact of Rising Electricity Prices

Families in Northern Ireland are grappling with soaring electricity bills, often averaging around £200 per month. For electric vehicle (EV) owners, this adds another layer of expense, especially during peak grid usage hours when rates are higher.

Businesses aren’t immune to these challenges either. Commercial fleets reliant on grid-based charging are seeing operational costs climb as electricity prices rise.

Take Lynsey from Belfast, a customer of EECO Energy, as an example. After switching to solar power, her monthly electricity bill plummeted from approximately £200 to just £20.

"My monthly bill is down 90% from ~£200 per month to £20 per month. It’s had a huge impact on our family." – Lynsey, EECO Energy Customer

These rising costs aren’t just a financial strain – they also come with environmental consequences. Dependence on the grid remains a significant source of carbon emissions, undermining the green potential of EVs.

Carbon Impact of Grid Dependency

Charging EVs with grid electricity often negates their environmental advantages. Northern Ireland’s electricity grid still relies heavily on fossil fuels, meaning each EV charging session contributes to carbon emissions rather than reducing them.

If you’ve invested in an electric vehicle to cut your carbon footprint, this reliance on a fossil-fuel-driven grid means you’re still indirectly burning non-renewable resources every time you charge. The grid’s current energy mix makes "clean" electric transport less environmentally friendly than it could be.

The Northern Ireland Energy Strategy acknowledges this issue and is working to expand renewable energy sources to combat climate change. However, the transition to greener energy is progressing slowly, leaving EV owners dependent on less sustainable grid electricity in the meantime.

This is particularly problematic for businesses striving to meet sustainability targets. Companies that have adopted EV fleets to showcase their environmental commitment still find themselves contributing to carbon emissions through grid-based charging.

The urgency is clear. As EV adoption grows across Northern Ireland, the strain on the grid increases. Without a move towards renewable charging alternatives, the widespread shift to EVs could paradoxically lead to higher overall carbon emissions instead of reducing them.

How Solar EV Charging Works

Solar EV charging systems bring together solar panels, smart chargers, and battery storage to create a seamless, energy-efficient solution that saves on costs and reduces reliance on the grid.

Key Components of a Solar EV Charging System

At the core of a solar EV charging system are several interconnected components. Solar panels are the starting point, converting sunlight into direct current (DC) electricity. This DC power is then converted into alternating current (AC) electricity by an inverter, making it suitable for use in your home and EV charger.

A solar-compatible EV charger, often referred to as a ‘smart charger’, is central to the system’s efficiency. These chargers let you control when your vehicle charges and can prioritise using only solar-generated electricity. They automatically activate charging when there’s surplus energy from the panels.

Adding a battery storage system can significantly enhance the system’s efficiency. For example, EECO Energy’s Duracell battery systems store excess solar energy for later use. A 10kWh battery is sufficient for basic needs, while larger capacities, such as 15–20kWh, offer more flexibility depending on energy demands and weather conditions.

Since EVs require a minimum charging rate of 1.44kW, your solar panels must generate enough surplus energy to meet this requirement. Advanced chargers can bridge the gap by supplementing solar power with grid electricity when solar output is insufficient.

These components make solar EV charging systems adaptable for both homes and businesses, offering tailored solutions to meet diverse energy needs.

System Setup for Homes and Businesses

The setup of solar EV charging systems varies depending on whether it’s for a home or a commercial property, ensuring it meets specific energy requirements.

For domestic installations, careful planning is essential. Ideally, your roof should offer 20–30 square metres of unshaded space with southern exposure for optimal solar panel performance. If roof space isn’t suitable, ground-mounted systems are a practical alternative.

EECO Energy oversees the entire installation process, including notifying the local Distribution Network Operator (DNO). In some cases, the DNO may recommend upgrading the main fuse to handle the increased load. All installations adhere to UK microgeneration standards and the Microgeneration Certification Scheme (MCS).

The combination of solar panels and EV charging is becoming increasingly popular. According to a 2023 Zapmap survey, 29% of EV drivers in the UK have solar panels, a figure six times higher than the national average. By June 2025, over 450,000 UK homes are expected to have both an EV and solar panels.

For commercial properties, scalable and efficient solutions are available. Prefabricated units, like the 3ti Papilio3, integrate solar panels, battery storage, and multiple EV charge points into a single system. These units can support 12 x 22kW charge points and generate approximately 18 MWh of solar electricity annually.

Commercial systems are designed for quick deployment, with installation and commissioning often completed in just one day. This minimises disruption to business operations while providing a reliable charging infrastructure.

For context, a typical household solar PV system (1–4kWp) can fully charge a 40kWh EV battery in about eight hours. On average, annual EV energy needs are around 2,118kWh, much of which can be supplied by solar power.

For businesses, the technical benefits are clear. Commercial solar EV charging systems offer substantial energy capacity and can be expanded as fleet sizes grow, making them a practical choice for long-term energy solutions.
