The installation of a Solar Power System (PLTS) within the ideal conditions still uses the type of solar module with the same current and voltage characteristics. However, these ideal conditions can be different if the modules which are commonly used are no longer available on the market. Once there is damage or interference in the operation system such as cracks in the module plate, it will take significantly a long time to replace. This particular condition can obstruct the distribution of electrical power to its intended loads in the other end, therefore in order for solar panel system to be able to operate at its maximum capacity, it requires an alternative or approach to find such similar module replacement thus it can help preserving the sustainability of energy availability within the solar panel system. This study aims to analyze the mismatch characteristics effects of current and voltage in a certain solar panel installation towards the power output as well as to reconfigure solar module to improve its maximum power capacity. The method is to create the mismatch condition of the current and voltage on the solar module in the Series, Series-Parallel and Honey Combination configurations. The simulation is carried out by replacing the main solar module with a replacement solar module from 5% to 100%. The results shows that in I-V mismatch the power generated was 2,32% apparently doesn’t sicnificant affected towards the solar panel system (less 3% can be denied). However by reconfiguring solar modul from Series configuration to Series-Parallel configuration and Honey Combination, the maximum power loss from the mismatch condition can be inprofed by Series-Parallel configuration and the maximum power which can be sustained with Series-Parallel configuration reached up to 40% od the originally replaced module.
