Punch in your current bill and we'll show you, side by side, what staying on the grid costs over the next 12 months versus going solar with battery storage.
See how all 9 Irish suppliers rank on your exact usage, your recommended system size, and whether you qualify for this month's 2-for-1 panels + free second battery offer.
System size: – kWp · Estimated generation: – kWh/yr
Figures use each supplier's published new-customer discounted 24-hour urban rate, last checked 2 July 2026 — not their standard/out-of-contract rate, which is typically 20–40% higher and is what you'd revert to after 12 months. Rates change monthly and vary by meter type; check the supplier's own site for the live price before switching.
Annual usage of – kWh derived from your bill and current supplier's rate. Generation is modelled from your panel count (440W panels, ~900 kWh/kWp/yr for a well-oriented Leinster roof, adjusted for orientation). Self-consumption is modelled from your battery capacity. All figures are estimates — a surveyor will confirm exact panel layout, generation and pricing on site.
