Effectiveness of solar panel positioning and grid tie inverter (GTI) in generating solar energy in Indonesian houses

In Indonesia, most electricity powers are based on non-renewable resources, which is not good for climate change. Therefore, the use of solar panels based on rooftops is an excellent alternative way to reduce electricity use. Thus, the objective of this paper is to analyze the effectiveness of solar panel positioning and Grid Tie Inverter (GTI) in generating solar energy for small- to medium-sized houses in Indonesia. Solar panel usage by residents living in the city may be limited, as the rooftop space in city houses is limited. GTIs can generate different types of power as they have different resources, this is good for climate change as no battery is needed In this research, two different solar panels with different positioning and angles, and connected to different types of GTI, were analyzed. The period of study was from 23rd July 2020 to 5th May 2021. The analysis was based on index comparison and movement of the sun during the said period. The result of the study indicates that the position and angle of solar panels affect the electricity generated by them. Solar panels placed in a horizontal position were observed to generate more power, and imported model inverters were observed to provide better electricity supply to homes.
