Description
Seven Cloud Sensor (3S-CS-MB)
-
Purpose: Measures cloud ratio to assess cloud impact on solar panel energy production, improving efficiency in PV systems, especially Tracker Systems.
-
Working Principle:
-
Contains two irradiance sensors:
-
One permanently shaded with a shading band to measure diffuse irradiance according to IEC 61724.
-
One fully exposed to sunlight to measure Plane of Array (POA) irradiance.
-
-
Cloudiness ratio is calculated from the ratio of these two irradiance measurements.
-
-
Advantages:
-
Determines whether panels should stay fixed or track the sun.
-
Reduces unnecessary tracker movement on cloudy days.
-
Optimizes energy output under low direct irradiance conditions.
-
Designed specifically for Tracker Solar Energy Systems.
-
-
Connection: Modbus RTU for integration with Datalogger or SCADA.
-
Installation Guidelines:
-
Mount on Shadow Tracker Sensor arm synchronized with the tracker system.
-
Avoid nearby heat sources for accurate readings.
-
-
Use Case: Enhances PV system efficiency and prevents energy loss on cloudy/overcast days.
