Sistema autónomo para registrar la irradiancia solar

Kurzfassung

We present a low maintenance system to record the solar irradiance in remote places or difficult access, with a ventilated thermal pyranometer, a rotating shadowband and a structure with movable supports. It is designed to work autonomously with a cleaning device that cleans the spherical glass of the sensor by blowing with compressed air and brushing; a rotating shadowband and a protection arm; a power supply comprising a battery and a solar panel; a control device with an electronic card coupled with the guiding means to establish the position of the shading band with respect to the sensor and to establish measurement intervals in sun and shadow conditions, according to geographical location, date, time of day and response time of the pyranometer. A data acquisition device records the measurements made and these are stored in Memory.
