Solar EV Charging System Components
Understanding the essential components of a solar EV charging system helps you make smart installation choices and keep performance high.
Solar Panels and Inverters
Solar panels and inverters are at the heart of the system, converting sunlight into usable power. Solar panels capture sunlight and turn it into direct current (DC) electricity. Modern PV panels typically produce 400–450 W each with 22–24% efficiency. To meet the energy needs of a household and an electric vehicle, around 12–20 panels are usually required (roof, usage and orientation dependent).
The inverter then converts the DC from the panels to alternating current (AC) for household use and EV charging. String inverters are common; where shading is a risk, power optimisers or microinverters can improve yield and monitoring. Most inverters now include app-based monitoring so you can schedule charging for peak solar hours.
Battery storage Systems
Adding battery storage turns your solar EV setup into a 24/7 energy solution. Residential capacities typically range from 5–20 kWh, and can scale comfortably up to ~100 kWh for high-end users. As a real-world guide, a 10 kWh battery can add roughly 35–45 miles of EV range, depending on vehicle efficiency.
Duracell battery systems are known for reliability and extensive warranty coverage. They integrate smoothly with solar, provide backup during outages, and use advanced management to optimise charge cycles — often lasting 15–20 years. Duracell batteries come with a 10,000-cycle guarantee.
EV Charge Points and Smart controllers
Most home EV chargers are 7 kW (single-phase), with 22 kW options for three-phase supplies.
Smart controllers act as the brains of the system — monitoring solar production, household load, battery state and EV demand in real time. They automatically prioritise energy flows (home → batteries → EV) and can respond to tariffs or forecasts to maximise savings and self-consumption.
Planning and Legal Requirements for Solar EV Charging in NI
