Star Semiconductor's IGBTs: The Core Force Driving the Efficient Development of the Photovoltaic Industry

With the promotion of global energy transition and sustainable development strategy, photovoltaic power generation as an important part of clean energy, is ushering in a golden period of vigorous development. In this context, the importance of IGBT semiconductor as the core device of PV inverter is becoming more and more prominent. This article will take the IGBT products of Starpower Semiconductor in photovoltaic inverters as an entry point to discuss the prospects of the photovoltaic market and the significance of the development, and to further introduce the Starpower semiconductor in the field of power semiconductor layout and development.

Wide prospect of photovoltaic market

Photovoltaic industry is in a rapid growth stage, the market outlook is very broad. In recent years, the global installed capacity of photovoltaic continues to grow rapidly. According to the forecast of International Renewable Energy Agency (IRENA), by 2030, the cumulative installed capacity of global photovoltaic will reach 3,000GW, an increase of nearly three times compared with 2020. The development of photovoltaic industry is of great significance for optimising energy structure, coping with climate change and promoting sustainable economic development. As a clean and renewable energy source, PV power generation can effectively reduce greenhouse gas emissions and ease environmental pressure.

Synergistic development of photovoltaic and energy storage

The combination of photovoltaic and energy storage technology is becoming a new trend in the industry. Photovoltaic storage systems can effectively solve the problem of intermittency and instability of photovoltaic power generation by combining photovoltaic power generation with energy storage equipment. According to Bloomberg New Energy Finance (BNEF) predicts that by 2030, the global installed capacity of photovoltaic + storage system will reach 1,028 GW. This synergistic model not only improves the efficiency of photovoltaic power generation, but also provides a more stable supply of electricity for the grid, further promoting the large-scale application of new energy.

Starpower Semiconductor IGBT products in the application of photovoltaic inverters

In the photovoltaic power generation system, the inverter is the key equipment connecting the solar panels and the power grid, and IGBT as the core device of the inverter, in which plays a vital role. As a leading IGBT supplier in China, Starpower Semiconductor's products have been widely used in the field of PV inverters.
