Solar energy is playing an increasingly dominant role in the energy industry. Forecasts for 2018 anticipated that new solar power systems with a capacity of around 100 GW would be installed worldwide. The trade association SolarPower Europe even predicts that, within the next five years, more than 1,000 GW of PV power will be installed. The outlook for the storage market is equally promising. Bloomberg New Energy Finance predicts that the annual installation rate of stationary storage devices will increase significantly by 2030. The combination of a booming market, pressure to innovate, and plans for new production plants around the world means that manufacturers now need to expand production and utilize the latest technologies.
