Install the radiation meter base and adjust the angle of the radiation base.
Fix the collector case to the tripod main pole with the hoop.
Install the radiation transmitter.
Install sensors: The total solar radiation sensor should be installed facing south. The PV substrate component temperature sensor should be bonded to the back of the PV panel with silicone.
Tripod fixing: Dig a pit according to the actual anchor hole positions, pour concrete with cement and sand, and fix with M10 expansion bolts.
Routine Maintenance
Regularly clean sensor surfaces, such as the global radiation sensor, wind speed and wind direction sensor.
In bad weather such as hail and frost, cover the protective cover of the global radiation sensor in time.
At extremely low temperatures, the wind speed or wind direction sensor may freeze. Clean it in time when the weather improves.
In strong lightning weather, turn off the system power. If there is a professional lightning protection system near the monitoring station, it is recommended to connect the station to it.
The equipment and system require regular maintenance to ensure long-term stable operation.
