Português ES-S228S silicon-based radiometer is a solar irradiance measurement sensor specifically developed by our company for the photovoltaic power generation industry. It utilizes a silicon-based material with a structure similar to that of solar panels. This silicon-based material features high sensitivity, high resolution, and fast response. Furthermore, its spectral response and tilt error are extremely similar to those of solar panels, enabling it to accurately reflect the irradiance data of solar panels.
