Here in the Netherlands, net metering is almost phased out. Now you are seen as an energy producer and pushing electricity out into the net will carry a charge, like for any other producer. Also your production will not be counted against your usage 1 on 1, but less favorable (and in time at real time prices) This means you can be net paying at peak solar production (less your usage at the same time). Storage capacity is rising as a result. As a consequence I concluded a few years ago that if we put solar on our house, it only makes sense with ampls storage
