Solar power storage becomes a megatrend

Solar power storage becomes a megatrend

More and more solar power storage systems are being installed in Germany. This summer their number reached the 200,000 mark, despite uncertainties against the backdrop of the Coronavirus pandemic. According to the German Solar Industry Association this represents a doubling in just two years. One reason for this megatrend is significantly lower prices for solar battery storage systems. Their costs have more than halved in recent years. It is estimated that more than half of solar power systems  are installed with the appropriate storage system. More is needed: To implement the German government's climate targets, avoid an electricity shortfall and balance out fluctuations in renewable energy generation, market researchers believe that the storage capacity of battery storage systems in Germany will need to increase tenfold to around 18 gigawatt hours (GWh) in the next ten years. In view of recent growth rates and in anticipation of further declines in system prices the goal appears feasible. "More and more citizens and companies want to generate as large a proportion of their own electricity requirements as possible in a climate-friendly and inexpensive way with the help of photovoltaics. For this reason, the installation of a solar battery is now usually included in new solar roofs," CEO of the Bundesverband Solarwirtschaft (BSW) Carsten Körnig is pleased to report. "The trend is clearly toward solar, worry-free packages, consisting of a solar system on the roof, a solar storage tank in the basement and a solar filling station on the doorstep."
