Abstract
PV systems require continuous maintenance to ensure maximum performance.
This requires continuous monitoring and data logging. Current PV data log-
gers are either expensive, not fully automated, or do not log all needed data.
Our project aims to develop a relatively low-cost PV data logger that enables
the automated logging of all the needed data related to a PV panel. The data
that will be collected include irradiance using pyranometer sensor, PV body
temperature using type K Thermocouple sensor, PV current, PV voltage, hu-
midity, and pressure. The data need to be stored along with the date and time
which requires the use of RTC (real time clock) and SD card module. The auto-
mated logger should have the ability to store data o_ine and online on a remote
database when there is a WIFI connection. In order for the automated logger to
measure data correctly it must perform an automated real-time matching with
the load. This will be done by controlling a customized DC-DC converter using
a digital potentiometer. Moreover, in order to make the measurements without
interfering with the PV output power, the system will run on a rechargeable
battery that will charge using a separate solar panel.
