Market Segmentation

Inverter Type Insight

The central inverters segment dominates the global market. The central inverter is a huge grid feeder. It is commonly used in solar photovoltaic systems with rated outputs greater than 100 kW. Typically, floor- or ground-mounted inverters convert the DC power generated by a solar array into AC power for grid connection. The power of these devices varies from around 50 kilowatts to 1 megawatt, and they are suitable for indoor and outdoor use. In general, a central inverter comprises a solitary step for converting direct current (DC) to alternating current (AC). Certain inverters are equipped with a supplementary DC-DC boost stage to augment their Maximum Power Point (MPP) voltage range. In some instances, low-frequency transformers increase the AC voltage and provide isolation at the output. This decreases efficiency and increases the inverter's size, weight, and price.

Application Insight

The utility-scale segment owns the highest market share. The number of utility-scale projects around the globe is increasing rapidly, and choosing the best inverter is increasingly important to efficiently generate a massive amount of energy for the solar PV project. Moreover, utility-scale solar has generated clean, reliable electricity at a stable cost for decades. Developing utility-scale solar power is amongst the quickest ways to reduce carbon emissions, which is one of the major drivers for the widespread installation of PV inverters over the forecast period.

• For instance, in 2022, under the Renewable Energy Power European Union (REPowerEU) plan, the European Commission aims to increase renewable energy, and solar energy will be the kingpin of this effort.
