My bill was €316 bimonthly at €0.31/kWh before I put in panels. Last bill covering the two sunniest months I've ever seen in Western Europe was €100 exactly, of which in excess of €50 was the standing charge that is due regardless. The remaining ~€25/mo overage is the delta of our demand and the inverter's peak output. Next purchase will be more panels; another inverter would offer only marginal gains.
