How to read the radiation value of photovoltaic panels

Measurement of Solar Radiation

In PV system design it is essential to know the amount of sunlight available at a particular location at a given time. The solar radiation may be characterized by the measured solar irradiance (power per area at a given moment) (or radiation) and by the solar insolation (the energy per area delivered over a specified time period).
