Current analysis has proven that floating PV vegetation might have superior era capabilities in comparison with ground-mounted PV vegetation in lots of areas of Bangladesh. As well as, the examine 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 performed a techno-economic evaluation to evaluate their nation’s potential for floating photo voltaic improvement primarily based on a choice of waters.
“The strategy for FPV plant remark is utilized in seven synthetic lakes in several areas of Bangladesh,” stated the scientists, noting that the proposed methodology could 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 era, financial affect, and contribution to the nationwide grid.”
The proposed methodology works by way of the next six steps: 1) Choice of water our bodies; 2) Choice of PV panels; 3) Calculation of generated energy; 4) Plant design; 5) Financial Evaluation; 6) Comparability of ground-mounted PV vegetation.
The crew additionally identified that it wants a “conservative strategy” as a result of it considers 15% of the full lake space for floating PV set up. “Nevertheless, the examine was additionally carried out for 20% and 25% of the full space maintaining 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.
In addition they thought of Joydia Baor, Bukhbhara Haor, and Barapukuria Lakes positioned outdoors Dhaka and stated these lakes have been really helpful by the Asian Growth 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 challenge. They discovered that, among the many three lakes in Dhaka, Hatirjheel Lake has the potential to generate the very 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. “By way of financial analysis (LCOE, NPV, and IRR), every of the proposed vegetation reveals challenge 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 positioned within the seven analyzed lakes can vary from $0.0341/kWh (Gulshan) to $0.0486/kWh (Dhanmondi).
Their findings are introduced within the examine “Techno-economic evaluation of energy era potential from floating photo voltaic photovoltaic programs in Bangladesh,” revealed in Hellion.
