How Solar Panels and EV Chargers Work Together
Solar panels and EV chargers complement each other to maximise energy efficiency. The process involves converting sunlight into electricity, managing that energy effectively, and funnelling it where it’s needed – whether that’s to power your home, charge your electric vehicle (EV), or send excess energy back to the grid.
Here’s a closer look at how energy flows from the sun to your EV.
The Basics of Solar Energy Flow
When sunlight hits the photovoltaic cells in solar panels, they generate direct current (DC) electricity. This energy is then prioritised. First, it powers your home’s immediate needs, such as lighting, appliances, or heating. Any leftover energy can then charge your EV, provided it’s plugged in. If there’s still surplus energy after that, it can either be stored in a battery system or exported back to the grid under the Smart Export Guarantee (SEG).
Smart chargers play a key role here, adjusting the charging speed based on how much solar power is being generated. For example, they can increase charging during bright, sunny periods and slow it down when the weather turns cloudy.
Battery storage adds even more flexibility. A system like the Dyness 10kWh battery, available for £2,400 from EECO Energy, can store the extra energy generated during peak sunlight hours. This stored energy can then be used later – whether to charge your EV overnight or to power your home when grid electricity is more expensive.
Time-of-use tariffs, which charge higher rates during peak hours (e.g., 4–7 PM), make this setup even more practical. Smart chargers and battery storage allow you to shift EV charging to off-peak times, saving you money.
Grid-Tied vs Off-Grid Systems
Grid-Tied Systems
Grid-tied systems are connected to the national electricity network, making them a practical choice for most UK homeowners. These systems let you draw power from the grid when your solar panels aren’t producing enough electricity – such as during the winter or extended cloudy periods – and export surplus energy under SEG schemes to help lower your electricity bills.
For EV charging, grid-tied systems provide reliability. Even during grey, overcast days in November, you can charge your car using grid electricity. The system seamlessly switches between solar and grid power as needed, ensuring a consistent energy supply.
Off-Grid Systems
Off-grid systems, on the other hand, operate independently of the national network. While grid-tied systems use the national network as a backup, off-grid setups rely entirely on battery storage. This means they require larger and more expensive battery banks. For context, a typical EV might need between 7kWh and 15kWh of electricity for daily use. An off-grid system would need around 30kWh of battery capacity to ensure several days of power, significantly increasing costs.
Maintenance is another factor to consider. Grid-tied systems benefit from the support of the national network, which eases the load on battery storage and can extend its lifespan. Off-grid systems, however, often require more frequent battery replacements, adding to long-term expenses.
For homeowners in Northern Ireland, grid-tied systems are usually the most practical option. They balance reliability, cost-efficiency, and ease of use, especially given the region’s existing electricity infrastructure and renewable energy incentives. This approach offers a solid foundation for integrating solar panels with EV charging in the area.
