6 FAQs about [Water channel under photovoltaic panel]

Do photovoltaic panels reduce evaporation?

In addition, shade from the photovoltaic panels has been shown to mitigate evaporation and potentially mitigate aquatic weed growth. However, the evaporation savings and financial co-benefits have not been quantified across major canal systems.

What types of PV can be used for underwater applications?

Later in the future, other types of PVs can be considered for underwater such as Perovskite (Liu et al., 2022), DSSC, organic (Kong et al., 2019), and tandem structures PV. However, the other considered element for this type of application is high encapsulation which will stop penetrating the water into the material.

How do water-surface photovoltaic systems affect community composition?

We found that water-surface photovoltaic systems decreased water temperature, dissolved oxygen saturation and uncovered area of the water surface, which caused a reduction in plankton species and individual density, altering the community composition.

Are water-surface photovoltaic systems a source of renewable power?

The implementation of water-surface photovoltaic systems as a source of renewable power has expanded rapidly worldwide in recent decades. Water-surface photovoltaic avoids negative impacts on terrestrial ecosystems, while the impacts on aquatic physical and chemical properties and biodiversity are unclear.

What are the three areas of a photovoltaic system?

Each study site was classified into three areas: (1) photovoltaic area (PA), the area covered by photovoltaic modules; (2) NPA, the area adjacent to the PA in the same waterbody, and (3) control area (CA), a nearby waterbody with similar size but not connected with the waterbody of PA.

Do water-surface photovoltaic systems reduce plankton species diversity?

Plankton species richness and individual density, and bird diversity decreased where water-surface photovoltaic systems were installed, according to a field survey in the Yangtze River basin, China during the winter and summer of 2022.
