Battery Storage Retrofit

Your solar makes power all day.
Make it work all night too.

Exporting for cents

The average feed-in tariff in Ireland is just 19c/kWh — yet you're buying that same electricity back for around 30c in the evening.

No solar after dark

Your panels stop producing at sunset. Without storage, you're 100% reliant on grid electricity for your highest-usage evening hours.

Prices keep rising

Irish electricity prices have risen over 60% since 2020. The gap between what you export and what you pay keeps widening.
