Grid - connected photovoltaic power generation many people will have misunderstandings and think that power generation will generate radiation, but not so. Grid - connected photovoltaic power generation is the generator principle of solar module, which converts solar energy into electric energy and performs energy conversion in the visible light range. In this process, no other substance will generate, let alone radiation. The grid-connected photovoltaic power generation system utilizes the photovoltaic effect of solar panels, and the photovoltaic power generation system is connected to the grid to operate without the function of battery, which is also the advantage of grid-connected photovoltaic power generation and saves more energy. Grid - connected photovoltaic power generation not only can greatly reduce the cost, but also has high power generation efficiency and better environmental protection performance, which is very in line with the concept of modern sustainable development and applies energy conservation and environmental protection to various fields. Photovoltaic power generation directly converts light energy into direct current energy through the characteristics of semiconductors, and then converts direct current into usable alternating current through inverters, all of which have metal shields and conform to the electromagnetic compatibility certification stipulated by the world.
