Prospects of photovoltaic inverter chips

Will photovoltaic inverters be the first choice for energy generation?

This paper presents a comprehensive review of photovoltaic (PV) systems with more focus on PV inverters. At this stage, there is no consensus that this technology will play a major role or will be the first choice for energy generation in the future because of many reasons, the most important of which is its lack of efficiency.

Which country installed the most solar PV inverter in 2018?

With 44.4 GW of annual installations and 48.7% of the global market, China was the most prominent country in the global solar PV inverter market in 2018. After China, the United States registered annual installation of 10.9 GW, representing 12% of global solar PV inverters installed in 2018.

What features are required for future PV inverters?

Cost reduction, higher reliability, higher efficiency, multi functionality and new topologies are the main features required for future PV inverters.

How much does a PV inverter cost?

PV inverter price is around 8%-12% of the total PV system cost (Xue et al., 2011). Impressive progress has been made in the last decade in reducing both PV inverter and PV module/cell costs (Raugei and Frankl, 2009, Fraunhofer ISE, 2015b). In 1990, the PV inverter cost was 1 EUR/Wpand this was reduced to almost 0.1 EUR/Wpin 2014.

What are the challenges of SiC-based PV inverter?

However, the SiC-based PV inverter is challenged by many issues, as shown in Fig. 12. Due to the very fast switching speed, high dv / dt, and di / dt, the employed SiC devices cause serious ringing, cross-talk, etc. These issues are discussed in detail as follows. Fig. 12. Configuration of SiC-based PV inverter with challenges. 4.1.

How long do PV inverters last?

For reliability, the statistical failure rate and designed life expectancy of PV inverters are 0.9/year and 15 years, respectively . The inverters is generally considered one of the weakest points in a PV generation system. The output power of a PV module fluctuates and is random.
