The study of Palaloi et al. (2023) evaluated the rooftop solar power system with the building''s low-voltage distribution grid system. The results show that the immediate PV power contribution ratio to the building''s load can reach 68.5%. PV modules also improve voltage, especially on public holidays.
The assessment methods of the impact of rooftop PVs on the distribution network have been the focus of the research community in recent years. The main challenge is to create a computational framework to deal with the uncertainty from PV system.

The excessive PV penetration also the root cause of voltage stability and has an adverse effect on protection system. The aim of this article is to extensively examines the impacts of rooftop PV on distribution network and evaluate possible solution methods in terms of the voltage quality, power quality, system protection and system stability.
The integration of rooftop PVs into low voltage feeders could potentially improve or deteriorate the VUR. The connected phase and the location of rooftop PVs are the determining factors on how PV generation will impact the voltage unbalance.
Because of the intermittent and unpredictable nature of the PV panels due to changing meteorological conditions and the variable supply/demand balance, rooftop PVs cause voltage and frequency changes in the network when they are integrated into the power system, especially when the penetration rate is high.
Many countries have experienced a surge in the level of the penetration of solar PV systems in the last decade. A huge portion of the newly deployed PV systems are connected to low voltage Grid. High Penetration of PVs at this level could potentially disrupt the normal operation of distribution network.
