Hot-spotting is a common problem in solar panel configurations that can potentially damage photovoltaic cells by forcing the conduction of reverse current in shaded or dysfunctional cells. The proposed invention offers a solution at the modular level by incorporating the photovoltaic panel into an open circuit to prevent hot-spotting. As a result, other panels in the photovoltaic string will remain functional under all adverse conditions.
Researchers from the University of Illinois have developed a method and apparatus to protect solar cells from hot spotting and damage resulting from arc faults. This device would also provide a way to shut off the solar array remotely. By preventing the damage caused by hot spotting and arc faults this device increases the longevity of solar arrays. It also reduces the risk of fire and provides a remote way to cut the power in cases of emergency.
Researchers from the University of Illinois have developed a new method to reduce the distortion in the output c urrent of multiple inverters used in DC to AC power conversion. This new technology helps to reduce the size and cost of the power electronic components currently used in power conversion. Also, this method is scalable and so this concept can be implemented on micro-scale systems.
