Monitoring PV Panels on Jin Jeop Library

Two Apogee Instruments SP-110 Silicon-cell Pyranometers have been integrated by Daeyeon CNI as part of a PV monitoring system at the Jin Jeop library located in Namyangju city, Gyunggido, Korea. The library has a PV power generation facility on the roof of the building that is converting DC voltage to AC voltage and suppling power to the building for electric lamps, air conditioning, and water heaters. Jin Jeop Library in Namyangju City, Gyunggido, Korea The two SP-110 pyranometers are mounted to the side of the PV panels. One pyranometer is mounted horizontal to measure the global solar irradiance, and the other is mounted tilted in the plane-of-array to measure global tilted irradiance or plane-of-array irradiance. Although the pyranometer measuring plane-of-array irradiance is mounted at the same angle as the PV panels and is measuring the irradiance the panels are receiving, both pyranometers are being used to monitor the system. Top pyranometer is measuring plane-of-array irradiance. Bottom pyranometer is measuring global horizontal irradiance. The data from the SP-110 sensors allow the integrator to see when irradiance measurements for the PV panels are below the accepted threshold to maintain the PV system. They are then able to use the data from the pyranometers and other instruments that are providing panel temperature, current, and voltage data to investigate the system and fix or replace bad electronic parts and PV panels. Apogee Instruments SP-110 Silicon-cell Pyranometers collect global horizontal irradiance and plane-of-array data to monitor the PV system at Jin Jeop Library in Korea.

Solar Power on Lakes and Dams

Korea Water Resource Corporation (K-water) is the number one clean energy producer in Korea. The company operates several clean energy plants including hydropower, tidal power, wind power, and solar photovoltaic power. More recently K-water developed the world’s first ecofriendly floating solar photovoltaic power system called SOLATUS, which was installed at Hapcheon Dam. The company plans to install additional floating photovoltaic power plants on dams and lakes in Korea by 2022. Part of the installation process is determining the best location for the power plant. To find these locations K-water is studying solar radiation at different angles, using a configuration of eight Apogee SP-110 Silicon-cell Pyranometers, and weather data, using wind, temperature, and humidity sensors.   Once K-water has collected all of the data from the sensors it will be reviewed to find the best location for the new power plants and the optimal angles for the solar panels to collect power throughout the day.
