Summary / Abstract: Nowadays renewable energy is not an option anymore, rather it had become an essential source of energy. Among renewable energy, photovoltaic(PV) generation had drawn attention for past decade. The most of the existing PV systems were installed on ground but due to its land space consumption, installing PV system over water or sea is becoming new promising options. In this study two types of PV modules (Monofacial and Shingled) are installed at two different installation environments: on rooftop and on ocean body. Shingled module is also known as high density PV module, and it is capable of producing more electricity at given surface area of PV module by inserting more PV cells through cutting them into pieces and connecting them without Pb ribbons. Data were collected for two days in September for both installation condition and analyzed to see at which condition would shingled module be more favorable option. Generated power per surface area of each PV module was compared at both installation condition. Normalized values were compared, and the result showed that under rooftop condition, shingled PV module showed 7.07% more electricity generated than monofacial PV module whereas under marine condition, shingled PV module showed 12.68% more. This result would be because of cooling effect that could be achieved by environmental characteristics of water body. Therefore, shingled PV module would be more adaptive in marine PV system.
