Why Choose Battery Storage?
Use Solar Energy Anytime
Store excess solar energy during the day and use it in the evening when you need it most. Increase self-consumption from 50% to 80%+.
Reduce Grid Dependence
Rely less on expensive grid electricity. With a battery, you can use your own clean energy even when the sun isn't shining.
Backup Power Option
Some battery systems provide backup power during outages. Keep essential appliances running when the grid goes down.
Smart Energy Management
Modern batteries integrate with smart tariffs, charging from the grid during cheap periods and discharging during expensive times.
Maximise your solar investment with battery storage. Store excess energy generated during the day and use it when you need it, reducing your reliance on expensive grid electricity.
Why Add Battery Storage?
Without a battery, you export 40-60% of your solar generation for just 5-15p/kWh. With a battery, you use that energy yourself, offsetting grid electricity at 28p/kWh+.

Battery Storage Questions
Is battery storage worth it in Northern Ireland?
Battery storage increases your solar self-consumption from 50% to 80%+, significantly boosting savings. While payback periods are longer than solar alone (10-14 years), batteries provide energy security and maximise your solar investment.
Can I add a battery to existing solar panels?
Yes, batteries can be retrofitted to most existing solar systems. AC-coupled batteries like Tesla Powerwall or Enphase are easiest to add. Our installers will assess compatibility with your current setup.
How long do solar batteries last?
Most home batteries are warranted for 10 years and typically last 15-20 years. Performance gradually decreases over time, with most retaining 80% capacity after 10 years.
What battery brands do you recommend?
We work with leading brands including Tesla Powerwall, GivEnergy, Enphase, Puredrive, and others. The best choice depends on your specific needs, budget, and existing equipment.
