Why Sunsathi Solar Uses SiC MOSFET Over IGBT – When it comes to solar inverters, choosing the right switching technology is crucial for ensuring high performance and efficiency. This is why Sunsathi Solar chooses SiC MOSFET over IGBT—because it offers several key advantages that make SiC MOSFETs (Silicon Carbide Metal-Oxide-Semiconductor Field-Effect Transistors) far superior to IGBTs (Insulated Gate Bipolar Transistors) in solar energy systems.
As a result, Sunsathi Solar leverages SiC MOSFET technology to achieve higher efficiency, reduced power losses, and improved thermal management. To illustrate this further, below is a point-wise comparison between the two technologies and how Sunsathi Solar benefits from using SiC MOSFETs over IGBTs in its inverters.

5.Thermal Performance
SiC MOSFET: Has superior thermal performance, capable of operating at higher temperatures (up to 200°C), making it more reliable in hot climates.
IGBT: Operates at lower temperatures (up to 150°C).
6.Cost
SiC MOSFET: Higher upfront cost, but the long-term benefits (higher efficiency, reliability, and longer lifespan) make it more cost-effective over time.
IGBT: Relatively lower cost, making it a budget-friendly option for general applications.
7.Applications
SiC MOSFET: Ideal for renewable energy systems, electric vehicles, and high-efficiency systems like solar inverters.
IGBT: Commonly used in motor drives, power supplies, and general inverters
