CENTER 533 can measure the energy and radiation that comes from the sun. It can quantify the sun’s energy on a specific surface accurately to optimize PV performance.
Solar energy measurement unit is solar irradiance W/m2 or simply watts per square meter. The measuring data can help to build the PV plant with an optimal size and at the best location/ angle/ orientation.
