- 1. DEVELOPMENT OF FLOATING SOLAR PV SYSTEM IN INDIA- 2024 (DFSPVI-2024) PRESENTED BY Prof(Dr.)Bijaya Kumar Mohapatra Associate Professor EEE Department. Einstein Academy of Technology and Management(EATM), Khordha. SWAMI VIVEKANANDA SCHOOL OF ENGINEERING & TECHNOLOGY, MADANPUR, KHORDHA 1st NATIONAL SEMINAR ON Date:- 06th APRIL,2024
- 2. INTRODUCTION Ever increasing power demand and depletion of fuels. Leads to shift our focus to renewable energy sources. Wind and hydro RE sources are area specific. PC can be installed an any place. Floating solar PV results is decrease in cost. Major issue of solar PV is requirement of land. But floating solar can be installed on any water bodies.
- 3. CONCEPT OF FLOATING PV
- 4. Major Components of FPV Technology I. Pontoon: For installation of floating PV plant, firstly, pontoon (floating structure) is constructed which easily and safely holds solar panels. It is a sturdy structure which is placed on water surface carrying panels and other electrical equipment's. PV panels are fitted on these pontoons maintaining suitable inclination to receive highest possible solar radiation. II. Mooring and anchoring system: The pontoon or floating structure is held securely with mooring and anchoring system. With the help of this system. floating structure can freely move or stay in a suitable position. III. Waterproof cable and connector: All cables remain on water, and the cabling is designed to be shock and waterproof. IV. PV system components: It includes PV panels, string inverter and other electrical equipment's which are essential for transmitting electricity.

- 6. FLOATING PV STRUCTURE Oceans Rivers Modular design on Flat water surface. Row spacing determined by floating structure. Consist of floating Islands. Anchoring and mooring system in essential. Need to provide maintenance walkways the water Floating platform Experiences forces form winds, snow, waves, and water currents. Cable routing to protects cables and connectors against the high-moisture environment. Ease and speed of the deployment given the side conditions and access the water. Maximize evaporative cooling effect of the PV modules for lower operating temperature and hence higher yield, or Minimize evaporation to conserve reservoir water.
- 7. BENEFITS OF FPV PLANT:- Arable land can be conserved by using water body. Unused water body can be converted into useful profitable renewable energy generation area. There is no land acquisition issue. More power can be generated by increasing the efficiency of PV panel. Floating PV panels require low maintenance cost. Cleaning process of PV panels is very easy. Water is conserved by reducing evaporation. Reduced water evaporation decreases the possibility of drought in the near area. Water clarity can be improved by reducing algae formation due to the constant shade on water surface.
- 8. CHALLENGES:- As the FPV system design is complicated, its installation requires much more investment cost and long payback period than the regular PV system. As entire FPV system remains on water surface, moisture content can affect on system components. FPV plant is always prone to natural calamities like heavy wind, storm, cyclone, flood and tsunami. Securing profitability is a challenging task as per unit generation cost is more than the regular PV plant. FPV system component's life span and durability can be affected by stress and vibration caused by water along with other environmental conditions. Selected site's water surface should be clean and dirt free else it can affect the system. The system installation in a sea is difficult. Aquatic system's biodiversity may be affected.
- 9. Environment and Social Impact Impact on local marine aquaculture due to the reduction in sunlight reaching the water surface. Impact on the fishing pattern. Impacts of shading of water surface on temperature stratification and dissolved oxygen levels. Impact on water quality. Inhibits the breakdown of chemicals by prompting high dissolved organic carbon concentrations potentially increasing the costs of water treatment. Impact due to leaching from materials. Impact due to exposure to electromagnetic fields associated with underwater electrical cables. Impact on hunting grounds of surface-diving birds. Impact on migratory birds habitats.

Comparison of development of floating and land-based photovoltaic projects Item Floating PV Land-based PV Terrain type may vary• Albedo depends on ground type• No move vary• Albedo depends on ground type• No movement j Operating environment Losses Performance i. Open and flat surface. ii. Low reflected diffuse light from water surface. iii. General presence of evaporative cooling and higher wind iv. speed. v. Presence of dynamic movement. i. Lower module temperatures (effect is dependent on climate) ii. Nearly no shading form near by objects. iii. Less soiling form dust, but potentially more form bird droppings. i. Overall higher initial performance ratio (5-10 %, climate specific) ii. Long-term degradation (e.g., potential induced degradation) is still uncertain. i. Albedo depends on ground type. ii. No movement. i. More temperature losses in hot and arid climates. ii. More source of shading and string mismatch. i. Yield prediction is better established.

- 14. CONCLUSION FPV system is a very effective renewable power generation system in the current scenario when fossil fuel is constantly reducing. This system, unlike the regular PV systems, is an eco-friendly power generation system for its efficiency in reducing water evaporation rate and thus helping in water conservation. It also can solve the persistent problem of land availability for installation of solar PV. Though its initial cost is higher than the regular PV system, a floating PV system generates almost 25% more power compared to the regular PV system.
