🌞 short version:

"Germany deploys 16.2 GW of PV in 2024"

Why and for whom? For anyone interested in concrete figures - here are the figures for Germany for the year 2024 (just for a helpful comparison and to make Europe even less dependent on fossil fuels in the future):

🌞 here comes the longer version:

"At 16.2 gigawatts, the expansion of solar capacity in 2024 was again slightly higher than in the previous year. ... At the end of 2024, the total installed solar capacity in Germany was 99.3 gigawatts."

Overview for DE:

"The installed output of renewable energy systems rose by almost 20 gigawatts to a total output of just under 190 gigawatts. Compared to the previous year, this corresponds to an increase of 12 per cent. The main contributors to this development are solar and wind energy."

Is there some information about the energy storage systems being installed in Germany to balance the solar and wind powers?

So currently roughly 20% of the total electricity consumption (~500TWh) would be produced by the renewables in Germany. If the increase in renewables stays roughly the same as in 2024, the 50% renewables production is reached around 2033 and around 80% in 2040.. There is immense need for energy storage though.

You're right (without having verified your figures) - the problems of grid & storage expansion (short-term over hours & long-term over days) are well known:

"A slight increase in the average gross capacity of the storage facilities can be observed in 2024. In addition, the commissioning of a large storage facility ... with a capacity of 174 megawatts was realised. Further commissioning of large storage facilities has already been noted in the register for 2025."¹

"The Fraunhofer Institute for Solar Energy Systems (ISE) has shown in a study that battery storage capacity ... must be expanded to 83 gigawatt hours by 2030 in order to fulfil the increasing requirements. This figure is almost 200 times higher than the current capacity. The urgency of this expansion becomes all the clearer when you consider the ... targets: at least 65% of energy is to come from renewable sources by 2030."²

Battery systems are somewhat fast to build, assuming that the actual batteries are commercially available. Based on some recent price estimates (like here: https://www.nrel.gov/docs/fy23osti/85332.pdf) the needed 90GWh of battery storage would cost around 27G€ to build (I used 300€/kWh cost estimate). Not impossible in any way, but certainly not insignificant either. Interesting to see what is the pace of these investments..
