Maybe we’ll get to the point. This news just shows us, that solar power can really be very impactful, even in not-so-sunny Germany. And that we’ve reached a turning point, where we can no longer ‘just’ put up more solar panels, but also start developping systems to store this excess energy in an economically feasible manner.

But actually, that’s nothing very new either. At least for home owners, who just put solar panels on their roofs, also investing in battery storage to use most of the produced energy themselves has been the economic strategy for a few years, since the price gap between what you got for putting energy into the grid, and what you had to pay for taking energy out of the grid was the only thing left that (economically) incentivized people to install solar power ever since the so called “Einspeisevergütung” subsidies have been dropped.
