How does salt spray affect a PV system?

The impact of salt spray and seawater on a PV system is described by the academics as a dynamic process through which salt spray creates a layer on the module, thus forming a water film on its surface. “At the same time, the seawater will also cover the surface of the PV module,” they emphasized.

Does salt spray reduce solar radiation?

The combined influence of salt particles, as a heating agent and a factor reducing solar radiation, resulted in a 10% yield reduction for the experimental PV system. The scientists concluded that more research is needed to understand completely the dynamics of the coexistence between salt spray and seawater.

Do salt particles affect solar power performance on ships?

Researchers in China have analyzed how the marine environment influences the performance of PV modules deployed on ships, and have found that salt particles can be detrimental to their performance as these act as both heating agents and a factor reducing solar irradiance.

Does salt spray increase solar irradiance?

When no more salt spray was sprayed, the solar radiation levels on the panels increased again, which shows, they went on to say, that the effect of salt spray is greater on solar irradiance than on temperature.

Does water spray affect electrical output characteristics of a PV module?

“The combined influence of water spray on the electrical output characteristics of [a] PV module manifests as a maximum power reduction of about 6%,” the research team further explained.

What are the advantages of Floating photovoltaic systems on water?

Floating photovoltaic systems on water have many advantages. The PV modules are placed on the water surface, because the water body has a good cooling effect on the modules, which can reduce the temperature of the module surface and increase the power generation of the modules.
