The growing demand for renewable sources to supply electricity along with the widespread adoption of string inverters across the commercial and residential sectors will stimulate the string inverter market expansion. Several government measures to implement renewable power generation to reduce carbon footprints will encourage the industry value.

There has been a significant impact of the COVID-19 outbreak on the global economy. In recent years, the pandemic has disrupted supply chains; therefore, increasing the cost of components & raw materials. However, the solar industry experienced a considerable surge in the shipment of string inverters due to the favorable government policies coupled with rising solar installations.

An inclining trend toward 1.5 kV solar systems to increase the PV power plant size in the utility and large commercial installations will fuel the usage of three-phase inverters

Three-phase inverters are used in all sectors including residential, commercial, and utility. These components are largely installed in the utility sector for applications in systems requiring below 1,500 volts on account of easy handling, better efficiency, and low maintenance compared to central inverters.

Growing regulatory concerns regarding the establishment of effective interconnection with grid-tied solar installations will increase the product penetration potential compared to its counterparts. Clean energy targets coupled with various government investments have bolstered the string inverter market revenue.

Increased reliability, affordability, and efficient features of string inverters will aid market demand in the residential sector

The string inverter market growth is attributed to the reduction in taxes combined with various government policies in countries including India, China, and ASEAN to promote the use of solar. For instance, in June 2021, China announced its plans for a new policy program to augment the rooftop development in pilot provinces including Hebei, Henan, and Shandong, which consist of over 20% rural residences. Various government initiatives along with the expiring Feed-in-Tariffs (FiTs) will positively influence the acceptance of string inverters in the residential sector. An increasing shift toward the integration of renewable energy sources and meticulous energy efficiency concord will foster the industry expansion.

In addition, an increase in large-scale PV projects in several nations to establish an affordable and sustainable power generation source will encourage the demand for these systems in the utility sector. Inverter designs equipped with Silicon Carbide (SiC) and Gallium Nitride (GaN) components increase power densities and reduce cooling requirements, thus reducing the overall system cost and weight, in turn, boosting the string inverter market progression.
