Solar Energy Systems

Wolfspeed's devices offer field-proven reliability and higher efficiency than traditional silicon devices.

Powering Everything Under the Sun

Affordable, widely available and increasingly efficient, solar power is one of the fastest-growing renewable energy options for residential, commercial, industrial and utility-scale applications. However, harnessing the sun’s power takes efficiency and reliability, which makes Wolfspeed Silicon Carbide (SiC) an excellent choice for solar energy systems to make smaller, lighter and more efficient systems.

Wolfspeed WolfPACK with pre-applied TIM reduces TJ by 40°C or can increase current capability by 60% over standard grease solutions.

Build a Better Inverter with Wolfspeed Silicon Carbide

Photovoltaic solar panels are the most visible part of the solar energy system but connected to the panels is another critical component: the solar inverter. Solar inverters are responsible for converting DC current into grid-ready AC current quickly, efficiently and with minimal energy loss. Using Wolfspeed Silicon Carbide in your inverter can significantly improve efficiency and drastically increase switching frequency resulting in smaller, lighter, lower cost systems.

Power Optimizers Boost Output Voltage

The amount of power generated with individual photovoltaic panels in a solar array can vary, leading to reduced overall system output. Whether implemented in distributed Power Optimizers, or as the first stage of a solar string inverter, Silicon carbide devices can enhance the efficiency and switching speed of the Maximum Power Point Tracking (MPPT) circuit to boost power into a constant, higher voltage to the internal bus. This DC is then converted to grid-standard AC by the inverter circuit. Using Wolfspeed Silicon Carbide MOSFETS and Schottky diodes in MPPT boost designs is a cost-effective way to maximize performance and get the most power out of your solar energy system.
