Manual Soiling Sensor Manual Soiling Sensor SEVEN Soiling Sensor is designed to measure the loss of energy production due to pollution caused by environmental factors in photovoltaic panels. The Soiling sensor, which is suitable for commercial, utility, industrial and rooftop projects, notifies the user of production losses due to pollution. If soiling ratio read from the sensor is 10%, it means that there is 10% energy loss in the facility. PV Soiling = Energy Loss SEVEN Soiling Sensor calculates the soiling ratio of the PV system by comparing the irradiance values received from the two clean and dirty irradiance sensors. While the dirty irradiance sensor in the system is exposed to contamination in the same way as the panels, the clean irradiance sensor is cleaned manually by the user with a wet cloth. SEVEN Sensor has a 3S-SMS-MB model that performs this cleaning process automatically. Monitoring systems give the user energy loss by comparing the two irradiance values according to the data received from the cleaned and dirty irradiance sensors. Normalized Irradiance Normalized Irradiance(Clean Cell) According to IEC 61724-1, the soiling ratio should be calculated as a single soiling ratio with a daily average. It is recommended to calculate only one soiling ratio per day for the system because although SEVEN provides instantaneous soiling ratio values, frequent measurements are affected by irradiation fluctuations. According to the IEC 61724-1 standard, low irradiation values and unstable weather conditions should not be included in the calculation. In addition, these measurements must be made within ±2 hours from local noon time. The user decides on the cleaning of the module by checking the soiling ratio to avoid loss of production and increase the efficiency of the PV system. • Economic Solution • Fast & Simple to Install • Manual Cleaning of Dirty Sensor • Free Software Update • SunSpec Compliant • SEVEN Remote Setup Service • SEVEN Customer Support Pinarcay OSB Mahallesi Organize Sanayi Tesisleri Teknokent Idare Binasi No: 7, D:1, 19100 Merkez / Corum / Turkiye • Phone: +90 364 230 1233 • Website: www.sevensensor.com • Email: [email protected]
