👉 Solarometer is a device used to measure sunlight intensity, usually in order to monitor the photovoltaic (PV) system's performance. It consists of a light source that emits photons at specific wavelengths and a detector that measures these photons based on their energy levels. The solarometer typically has a light-emitting diode (LED) or photodiode as its primary sensor component, which is sensitive to changes in the intensity of sunlight. The LED or photodiode converts the incident light into an
