Photovoltaic (PV) panels in marine environments are often exposed to seawater wave-splash, salt spray, high humidity, strong winds that can decrease system performance, service life and reliability. When seawater splash on PV panels, after evaporation salt crystals are left behind on panels' front surface. Seawater distribution and salt accumulation depend on PV system construction and wave conditions. Also, certain environmental factors can make additional influence (e.g. higher wind speed lowers PV panels temperature, higher relative humidity has influence on solar radiation scattering and can decrease it). Although PV panels in marine environments experience specific challenges, in available literature there are not many papers examining PV power loss dependence on sea salt deposition. At the Faculty of Maritime Studies Kotor, University of Montenegro outdoor experiment was conducted in order to determine seawater influence on PV panels power. The experiment was performed outdoors, on the roof of the faculty building with no shadows where two identical flexible monocrystalline silicon PV panels power of 300 Wp were placed one beside the other. One PV panel remained clean during the experiment and the other one was sprayed with seawater taken from the Boka Bay in front of the faculty building. Spraying of seawater was performed evenly on the PV panel surface, as much as possible. After seawater deposition on the PV panel and seawater evaporation, electrical parameters of both PV panels were measured with SOLAR I-Ve 1500 V multifunction I-V curve tracer. Power of the PV panel covered with seawater salt crystals was on average 6.17% lower compared to the clean PV panel. Even after several depositions of seawater, power decrease was similar. Upon every next seawater application, some of the salt crystals were removed due to spraying of new seawater quantity. Similar happens in cases with wave-splashing, since waves remove evaporated salt crystals. Conducted experiments showed that repeated seawater splashing and salt crystals appearance after seawater evaporation do not have significant influence on PV panel’s power.
