Is already happening for over a year. PV sales is down by 90%, last year there was a sellout of PV companies on brookz.nl and this year they are going mostly bankrupt.

Consumers are now having a PV problem because they have to pay for their panels (I was asked to pay 800 euro per year). So, there is the incentive for many consumers willing to purchase a battery.

An alternative solution is the position of the panels. It is useless to have panels facing south, and don't use the roof, use the facade to improve the off season performance.
