Current analysis has proven that floating PV vegetation could have superior technology capabilities in comparison with ground-mounted PV vegetation in lots of areas of Bangladesh. As well as, the research reveals that floating arrays within the nation can attain a levelized price of power from $0.0341/kWh to $0.0486/kWh relying on the situation.
Researchers on the Bangladesh College of Engineering and Know-how carried out a techno-economic evaluation to evaluate their nation’s potential for floating photo voltaic improvement primarily based on a collection of waters.
“The tactic for FPV plant commentary is utilized in seven synthetic lakes in several areas of Bangladesh,” mentioned the scientists, noting that the proposed technique may be generalized and can be utilized in any potential floating PV plant views. “The abundance of every plant is extensively evaluated when it comes to energy technology, financial influence, and contribution to the nationwide grid.”
The proposed technique works by the next six steps: 1) Collection of water our bodies; 2) Collection of PV panels; 3) Calculation of generated energy; 4) Plant design; 5) Financial Evaluation; 6) Comparability of ground-mounted PV vegetation.
The workforce additionally identified that it wants a “conservative method” as a result of it considers 15% of the entire lake space for floating PV set up. “Nonetheless, the research was additionally carried out for 20% and 25% of the entire space holding in thoughts the long run growth of the plant,” it added.
Of their evaluation, the teachers thought of three our bodies of water within the space of the nation’s capital Dhaka – the Dhanmondi Lake, the Hatirjheel Lake, and the Gulshan Lake. “These are the one man-made our bodies of water within the capital,” they specified.
Additionally they thought of Joydia Baor, Bukhbhara Haor, and Barapukuria Lakes situated outdoors Dhaka and mentioned these lakes have been really helpful by the Asian Improvement Financial institution (ADB) as potential websites for floating photo voltaic.
They used PVGIS-SARAH, a worldwide photo voltaic irradiation database, to find out the put in capability, the required floor, and the panel effectivity of a floating venture. They discovered that, among the many three lakes in Dhaka, Hatirjheel Lake has the potential to generate the best quantity of electrical energy at 19.3 MW and Dhanmondi Lake has the least at 5.1 MW, whereas Gulshan Lake can obtain or 17.1 MW.
Amongst different lakes, they discovered that Joydia Baor can deploy a floating PV capability of 34.30 MW, with Bukhbhara Haor and Barapukuria Lakes reaching 34.07 MW and 17.43 MW, respectively.
“The findings present that the proposed vegetation in Dhaka can meet 1.1% of the town’s complete demand, and that the one in Kaptai Lake can fulfill 7% in Chattogram, the port metropolis of the nation,” emphasised the scientists. “When it comes to financial analysis (LCOE, NPV, and IRR), every of the proposed vegetation reveals venture viability after implementation.”
The teachers additionally say that the simulated floating PV vegetation present extra producing capabilities in comparison with ground-mounted PV vegetation. The latter is alleged to have the potential to generate 4.0 kWh/m2 to six.5 kWh/m2 per day, whereas floating PV vegetation can attain as much as 8.3 kWh/m2. “Though the proposed FPV vegetation will initially price greater than the inland PV vegetation, the deliberate vegetation have extra income producing capabilities than the land counterparts,” they concluded.
As well as, the researchers discovered that the extent power prices of floating photo voltaic vegetation situated within the seven analyzed lakes can vary from $0.0341/kWh (Gulshan) to $0.0486/kWh (Dhanmondi).
Their findings are introduced within the research “Techno-economic evaluation of energy technology potential from floating photo voltaic photovoltaic programs in Bangladesh,” printed in Hellion.
