Can a floating PV system be used in water reservoirs?

This paper presents the development of a new floating PV system for use in water reservoirs. The innovative floating system is modular in design, comprising interconnected floating modules. An innovative standardised floating module has been proposed.

How do floating PV panels work?

The attachment to the floating modules is secured by means of bolt and nut connection. The pillow structure elevates the PV panel at one side so that a 10-degree tilt is obtained. As explained earlier, the tilt is needed to allow rainwater to wash off dust and bird droppings in order to maintain efficiency of PV panels. Fig. 4. Pillow module.

How much power can a floating PV system generate?

The floating PV system should meet a power generating capacity of 100 kWp. High density polyethylene (HDPE) material is chosen for the design of the floating modules in view of its material strength and durability in water bodies. Floating modules shall be able to support 1.65 m long by 1.00 m wide 270 Wp double glass solar panels.

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.

Does hydraulic cooling improve the optical efficiency of PV panels?

Bhakre et al. reviewed a performance evaluation of PV panel surfaces under hydraulic cooling. They found that continuous water flow over the top surface significantly cools the PV panel and cleans its surface. Hence, the optical efficiency of the PV panel is increased.

How do floating solar mounting systems work?

By harnessing the synergy of water and photovoltaics, floating solar mounting systems not only optimize unused water surfaces but also enhance the efficiency of solar panels by cooling them.
