Problems solved by technology

However, there are the following defects: the temperature of hot water output by traditional solar photovoltaic photothermal integrated components is not enough for direct use, especially in rainy weather with insufficient sunlight, so it must be continuously heated with the help of other auxiliary energy sources such as electricity; It can output hot water at a higher temperature, but it cannot generate electricity because it does not contain photovoltaic modules
