AI Technical Summary

Benefits of technology

This patented technology allows for efficient use of solar energy by converting sunlight into electrical current through specialized materials that can be used to store or release it effectively at different times during each day without losing its effectiveness due to excessive heat caused by lightning strikes. It also includes a system called a photoelectric control device (PC) which helps protect against damage from external factors such as weather conditions when turning off devices connected to main circuits. Overall this innovation improves efficiency and reliability of electricity generation systems while reducing their risk of failures.

Problems solved by technology

Technological Problem: Current Power Converting (PCC) systems used in PV applications require large voltages at different levels during their lifespan due to variations in brightness caused by environmental conditions such as cloud cover or shading on the surface being exposed to direct rays from the Sun's lens overcasting them onto surfaces like buildings. These technical problem addressed by this patented technology include ensuring reliable performance despite extreme weather conditions while reducing power usage and improving security measures when connecting multiple devices together through an AC/AC converter interface.
