The station is fully functional except of the DHI pyranometer ventilation unit. The pyrheliometer and pyranometers showed no significant increase in their Irradiation signal upon cleaning of the sensor head. It is recommended to clean the sensors on a daily basis in order to reduce the influ- ence of sensor soiling on the irradiance data. ESMAP Report 3 Pk-Isb-151215_CSPS_MaintenanceReport CSPS CSPS Tier1 Maintenance Report Concentrating Solar Power Services Completed Tasks  Foundations checked for integrity.  All parts and sensors of the station examined for damage, dust or condensed humidity, current status recorded and equipment cleaned where necessary.  Vertical alignment of wind mast checked, wind mast anchorage and wind mast guying ropes checked for stability, secure fixation to the ground and tightness.  Sun tracker alignment adjusted and fine-tuned, no perceptible influence on the irradiance data stated.  Irradiance sensor alignment and leveling adjusted and fine-tuned, no perceptible influence on the irradiance data stated.  CVF4 ventilation unit filters exchanged, GHI CVF4 ventilation unit repaired  Solar irradiation sensors checked for proper operation and functionality; sensors cleaned, impact of cleaning on data recorded.  Sensor cables on sun tracker checked.  Batteries Box and ACDC Converter inspected and correct operation of 12 VDC and 24 VDC circuits verified.  Maintenance platform checked.  Datalogger program correct operation verified.  Measured quantities checked for proper operation and correct values.  Cleaning inspection button checked for proper functioning.  Fuses, electrical components and wiring checked. Pending Tasks / Recommended Tasks for next Maintenance Visit  Repair or replace DHI ventilation unit fan (cables oxidized at connection point).

As can be seen from the panoramic view in Figure 21, these buildings block out the sun in the early morning between February and October and in the evening before sunset during the entire year. Figure 22: Shading occurences for all sun elevations Figure 22 shows that in the morning, this new building blocks the sun for almost an hour after sunrise during the months of March to October. The buildings in the west also cast some shadow on the sensors in the evening throughout the entire year. ESMAP Report 11 Pk-Isb-151215_CSPS_MaintenanceReport CSPS CSPS Tier1 Maintenance Report Concentrating Solar Power Services Figure 23: Shading occurences for all sun elevations >5° above horizon Figure 23 shows that after excluding sun elevations smaller than 5° above horizon, the new building in the east has some shading impact on the measurement data in the morning. As there is no way to avoid these obstacles now, the influence on the data will be considered in the evaluations. ESMAP Report 12 Pk-Isb-151215_CSPS_MaintenanceReport
