Your inputs
Your Property
Your Energy Usage
≈ 5.625 kWh / year at €0.32/kWh retail. We use this to size how much the battery can realistically shift.
Your System & Battery
How we estimate. Retail €0.32/kWh, export €0.10/kWh, so each kWh you store and use at night is worth about €0.22. We assume ~0.9 full cycles/day over 365 days, capped at 40% of your annual usage, a 900 €/kWh installed cost, and the Cyprus battery grant of €375/kWh (max €1,500). Figures are indicative estimates, not a quote — your real numbers depend on your roof, tariff and installer.
