Climate change, energy transition, decarbonization: Photovoltaics is currently experiencing the greatest momentum in its history globally and has been growing continuously for years. Within a few decades, a space technology in the kilowatt range has become a main pillar of our energy generation in megawatt power plant format. As well in Germany, the solar industry is finally achieving the relevance it deserves as a result of the recent energy and raw materials crisis. However, for a successful energy transition, ambitions must keep growing: the energy system and power grid need a renewal, and the rate of photovoltaic expansion should also be rethought. And it should be on the order of gigawatts per month.
