Recently, renewable energy has become increasingly important and the share of solar energy in particular has risen sharply. The increasing connection of alternative energy sources to the low or medium voltage grid requires new regulations. In  10 trends in the solar sector up to 2025 were compiled, from which potential requirements for power electronics and module manufacturers can be derived. This paper considers 3-Level topologies from the point of view of some of these requirements and potential trends. These include: - the increasing requirements regarding reduced harmonic content and Low Voltage Ride Through (LVRT), - the potentially higher usage of wide bandgap semiconductors, - the energy storage capability and the associated extended power factor range.
