Photovoltaic regulation due to incentives

For us, the feed-in limitation applies only for 5 years and the subsidy is 3 times higher. I once did a rough calculation, and you should actively counteract this with consumption optimization and charging forecasts. 20 years is actually unreasonable, especially since no one can predict whether the storage will fail after 10+x years. Then you have no storage anymore and still the throttle. I would definitely forgo the subsidy in that case.
