East Asia Solar Monitoring Power Supply System

The global average, barring China, is over twice that of ASEAN countries, at 7% prospective capacity under construction. ASEAN countries have over 28 GW of operating utility-scale solar and wind capacity and a 20% increase in operating capacity since January 2023 and make up 9% of ASEAN countries' total electrical capacity.

The aims of research is to provide a direct and real time monitoring. This research has been carried out in solar power plants at Engineering Physics Department, FTI-ITS. The design of an ATmega32 microcontroller-based system that is integrated with Raspberry-pi as a data acquisition system.

Thailand is one of the largest producers of utility-scale solar and wind power in ASEAN, with over 3 GW of renewable capacity. Two-thirds of this capacity comes from onshore wind power. Thailand's national energy targets include 10 GW of solar and 4 GW of wind in operation by 2030 and net zero emissions goals for 2065.

A solar power plant monitoring website was successfully developed, which is used to display data or monitor the PV-VP performance, that can be seen on Figure 4. The real-time data is collected from the sensor installed in the solar power plant site. A web-server interface is included to provide external client connection and monitoring.

There are researcher who proposed a microcontroller based solar monitoring system. Kabalci, Gorgun and Kabalci introduces a real-time monitoring system of a renewable energy generation plant that is constituted with a wind turbine and solar panel arrays. The monitoring platform is based on current and voltage measurements.

Due to high influence of solar iradiance, PV temperature and the ambient temperature on the PV performance, this parameter should be monitored and analysis to get the best operating condition. The designed monitoring system is able to collect and represent the effect of this parameter on PV perfomance.
