Solar power provides a renewable, clean source of electricity. Solar power is also scalable meaning that it can be used to power a single household, or it can be deployed on an industrial scale. Solar applications need to guarantee long lifetimes of greater than 20 years, excellent thermal behavior, and high-power density to increase power in the same form factor or to enable integration with the panel. GaN devices are being widely adopted for solar applications because they offer significant benefits for efficiency, size, weight, and long lifetime.
