Ireland Household Energy Storage Project

This 10kW hybrid solar system for an Irish household maximizes self-consumption of rooftop solar energy while exporting surplus power to the grid. A hybrid solar inverter, a 15kWh lithium battery and a 10kW LONGi all-black panel array work together to cut electricity bills, provide backup during outages and keep generating reliably through Ireland's changeable maritime weather.

System Configuration

System Components

1. Hybrid Solar Inverter

The hybrid inverter manages solar generation, household loads and battery charging in one unit. It prioritizes using solar power directly, stores any excess in the battery, and exports remaining surplus to the grid — switching automatically to backup mode if the grid fails. 3-year warranty.

2. 15kWh Lithium Battery

The 15kWh lithium battery holds surplus daytime solar energy for evening and night-time use, reducing the need to import expensive grid electricity. Built-in BMS protects and balances every cell for long cycle life and safe operation. 3-year warranty, CE / IEC / UN38.3 certified. View battery details →

3. LONGi All-Black Solar Panels

The 10kW rooftop array uses LONGi all-black modules, which deliver strong low-light and diffuse-light performance — important under Irish cloud cover — while their uniform black finish gives the roof a clean, premium appearance.

Why This System Fits Irish Homes

• Lower bills against high electricity prices — self-consumption shifts daytime solar energy into evening peak hours when grid tariffs are most expensive
• Income from surplus export — power the home cannot use or store is fed back to the grid instead of being wasted
• Reliable in a cloudy climate — all-black LONGi modules harvest diffuse light well and keep generating on overcast days
• Backup during outages — the battery and hybrid inverter keep essential loads running if the grid supply is interrupted

Frequently Asked Questions

How much of an Irish home's electricity can this system cover?

With a 10kW array and 15kWh battery, a typical household can cover a large share of its annual consumption — using solar directly by day and stored energy in the evening, with only shortfalls in very dark winter periods drawn from the grid.

What happens to surplus solar electricity?

The system first powers the home, then charges the battery, and any energy still left over is exported to the grid under Ireland's micro-generation arrangements, reducing overall energy costs.

Do solar panels work during an Irish winter?

Yes. Output is lower in short winter days, but the all-black panels perform well in diffuse light and cool temperatures. The battery stores whatever is generated, and the grid remains available as backup.

What warranty is included?

The inverter and lithium battery carry a 3-year warranty. GreenMore and its Irish installation partners provide monitoring, maintenance and spare parts support.
