Prices for German solar power storage systems have reportedly fallen 25% since the spring. The data come from the German Solar Industry Association (BSW-Solar).
Also according to BSW-Solar, approximately 15,000 German households now use battery storage combined with solar power, and that number has been growing faster and faster as the costs have come down. As an example of that, KfW, Germany’s development bank, approved 32% more funding applications for home storage in the third quarter of this year than in the second. Needless to say, I think word is getting around that this is a smart move for many now that storage costs have fallen.
