The energy transition from fossil fuels to new and renewable energy is on the rise as the Earth's surface temperature is increasing. This makes the use of renewable energy power plants also increase. Indonesia as a tropical country has high potential in the field of renewable energy based on solar energy. This potential is utilised with the use of solar power generation systems. The performance of solar power generation systems is affected by module temperature and sunlight irradiance. An increase in PV module temperature can reduce the performance of the solar power generation system. Solar power plants as a technology in general can experience failures that can damage their components. One of the causes of this failure is the presence of shading. Both conditions can result in reduced performance of the solar power plant. This research will simulate PV module strings under normal and shaded conditions with different PV module temperature and iradiance variations. The simulation is done by modelling the PV module string using Simulink in MATLAB software. This simulation data is then analysed to see the type of relationship between the PV module temperature under shaded conditions and the performance of the solar power generation system and to see the effects that occur in the solar power generation system based on the calculation of the performance ratio and fill factor. The effect can also be seen from the characteristics of the I-V curve of the PV module string. The PV module string model has been successfully created and can produce simulation data with acceptable precision and accuracy values. The simulation data shows that the PV module temperature has an inversely proportional relationship with the performance of the solar power generation system. In addition, the performance ratio value of the solar power generation system can drop below 80% when 25% of the PV modules are covered by shade. This research is expected to increase efforts in monitoring and maintaining the condition of the solar power generation system.
