How we calculate this
- • Electricity price: €0.35/kWh. Savings are estimated as a share of your bill, +15% if you charge an EV.
- • Generation cap: savings can't exceed what your system makes, estimated array size × ~900 kWh per kWp per year (typical Irish yield).
- • SEAI grant: solar PV grant up to €1,800, tiered by system size.
- • CO₂: 0.295 kg per kWh (Irish grid average).
