A dual solar cell pyranometer and a method of manufacturing the dual solar cell pyranometer. The pyranometer includes at least two transparent members, a plurality of encapsulation members, at least two solar cells, a sealing member, and a frame structure. The solar cells have the same size and technology, and have matching electrical specifications. The encapsulation members are adapted to bond the solar cells to the transparent members. The solar cells face the sky, and the other solar cell faces the ground. The dual solar cell pyranometer accurately measures the pyranometer value and eliminates errors in the measured pyranometer value due to a small temperature difference between the solar cells.

The present invention discloses a system and method for atmospheric observations. The system (100) comprises a sky observer (102) comprising a sky imager (104) to capture and communicate a sky image for analyzing cloud characteristics, a robotic sun photometer (106) to track and communicate the sun and measure aerosol properties, a pyranometer (108) with a shadowband (110) and a sensor unit (120) to measure environmental conditions and collect and communicate sensor data surrounding the sky observer (102). The system (100) comprises a communication network (114) communicatively connected to the sky observer (102) to collect aggregated atmospheric data comprising the sky image, aerosol properties, different components of solar irradiance and the sensor data and transmit the aggregated atmospheric data to a server (114). The server (114) receives and analyzes the aggregated atmospheric data to estimate impact of atmospheric conditions on solar energy production in a solar plant.

Disclosed is a system (100) for quantifying energy losses in a solar power plant due to malfunctioning solar trackers. The system (100) includes a processor (104) that filters tracker-day data (118) of the one or more solar trackers (116) based on predefined quality and quantity criteria to identify malfunctioning trackers. It determines whether energy losses are controllable or uncontrollable based on tracker mode information. Using a solar position and irradiance model, the system (100) estimates expected irradiance for each malfunctioning tracker. Energy loss is calculated by comparing the expected irradiance to the actual irradiance measured by a pyranometer on a properly functioning tracker, adjusted for the tracker's capacity. The system (100) categorizes the losses as controllable or uncontrollable and analyses these losses to identify patterns of the malfunctioning trackers, guiding appropriate maintenance actions.

The present disclosure relates to a pyranometer for measuring solar irradiance. In particular, the pyranometer comprises a dome (1), a thermopile-based sensor (2) comprising a receiving surface (22), a diffuser (3) configured to diffuse radiation passing through the dome (1) from outside the pyranometer towards the receiving surface (22) of the thermopile-based sensor (2), and at least one optical filter (4) arranged in the optical path of the radiation in front of the receiving surface (22) of the thermopile-based sensor (2) so as to modify the spectral composition of the radiation measured by the thermopile-based sensor (2).

The claimed invention relates to a pyranometer comprising: a dome, a thermopile-based sensor with a receiving surface, a diffuser configured to diffuse radiation from outside the pyranometer, passing through the dome, towards the receiving surface of the thermopile-based sensor, and at least one optical filter disposed in the optical path of the radiation opposite the receiving surface of the thermopile-based sensor to modify the spectral composition of the radiation measured by said sensor. According to the claimed invention, the distance of the optical path between the diffuser and the thermopile-based sensor is adjusted so that the radiation diffused by the diffuser onto the receiving surface of the thermopile-based sensor has a substantially conical shape.
