Within a floating solar mounting structure, solar modules are engineered to float upon water surfaces. These panels generate energy, which is then conveyed to a transmission tower via submerged cables. A significant rationale for the preference of this solar technology by numerous countries is the enhanced productivity it offers in comparison to conventional ground-mounted or roof-mounted photovoltaic panels.
What is a Floating Solar Power Plant?
Floating solar power plants are designed to float on the surface of reservoirs, quarry lakes, irrigation canals, tailing ponds, and other bodies of water.
The floating mounting structure is coated with a magnesium alloy to provide resistance against corrosion, while buoyancy is achieved by using polyethylene. Moreover, these panels exhibit a high humidity resistance and are lead- and dust-free.
The components integral to a floating photovoltaic project include PV panels, Floaters, Combiner boxes, a Mooring system, an Inverter, a Transformer, a Cable network, a Transmission System, and Floating walkways.
The photovoltaic panels are designed to capture solar radiation, which is then converted into usable energy. The interlinked plastic rafts on which these PV panels are mounted are called Floaters.
The mooring system employs anchors to secure these floating solar panels above the water surface.
Significantly, the combiner box aggregates the energy harvested from all the panels dispersed across the floating solar farm, directing it to the central inverter.
The central inverter transitions the DC electricity into AC electricity for utilization. Subsequently, this power is stepped down for transmission through the transformer.
A comprehensive network of cables acts as a conduit, coordinating the solar panels, combiner boxes, inverters, and transformers.
An inland connection line, identified as the transmission system, facilitates power transportation to the requisite locations. Conclusively, the floating walkways establish access points from the inland side.
Benefits of Floating Solar Plants
1. Land Conservation: Floating solar plants utilize water bodies for installation, thereby conserving precious land resources which can be used for agriculture or other developmental activities.
2. Water Conservation: By covering a portion of the water surface, these installations reduce water evaporation from reservoirs, lakes, or ponds, which is especially beneficial in arid regions.
3. Improved Efficiency: The cooling effect of water helps in maintaining a lower operational temperature for the solar panels, which can enhance their efficiency and longevity.
4. Reduced Algae Growth: By blocking sunlight, floating solar plants can inhibit the growth of harmful algae in water bodies, which in turn improves water quality.
5. Enhanced Energy Production: The reflectivity of water can potentially increase the amount of solar energy that the panels can capture, leading to higher energy production.
6. Compatibility with Existing Infrastructure: Floating solar plants can be integrated with existing hydroelectric power plants, allowing for hybrid systems that can generate power more consistently.
7. Reduced Installation Costs: In some cases, the costs of installing floating solar systems can be lower than land-based systems as there's no need for land leveling or foundation construction.
8. Aesthetically Pleasing: Floating solar installations can be aesthetically pleasing and can be designed to blend with the natural surroundings, thereby reducing visual pollution.
9. Reduced Transmission Costs: If floating solar plants are located near demand centers, they can help in reducing transmission and distribution losses, thereby reducing the cost of electricity delivery.
Floating solar plants are a testament to the innovation within the renewable energy sector, providing solutions that not only generate clean energy but also address land and water conservation concerns.
