“…It is necessary to take precautions to prevent overcharging and excessive battery discharge. In this research, it is recommended to use a solar charge controller with a solar inverter in order to (a) charge the battery as effectively as possible without overcharging and (b) stop the battery from nighttime back feeding into the solar panel (Grebenchikov et al, 2020). Solar charge controller prevents overcharging and excessive battery discharge.…”

In Bangladesh, there are roughly 31 marine passenger ships that are in operation. These ships might be a good location for solar photovoltaic (PV) plants since solar energy is the best renewable energy to replace the fossil fuel used in the ships. A “tower rounded flower-shaped solar PV” system of PV panel arrangement—just looks like a “sunflower,” is proposed in this research. To harness maximum power, solar towers are designed in such a way that they may be freely rotated on their vertical axes and that the tilt angles of their solar panels can be adjusted from 0° to 50° on their horizontal axes freely. The “tower rounded flower-shaped solar PV” architecture of the PV array atop a maritime vessel is presented in this research along with a unique method for calculating the PV system's anticipated energy production. Finally calculated the realistic CO2 emission reduction by using this approach for a sustainable future. Applying globalsolaratlas (for horizon and sun's path estimation); PVsyst 7.2, HOMER Pro, and NREL's PVWatt calculator (for solar radiation calculation); vesselfinder (for the number of vessels analysis); shiptraffic (for vessels path analysis), this research suggests that marine passenger vessels are one of the best places to construct a proposed “tower rounded flower-shaped solar PV” power plant. According to estimates, 17 passenger ships can produce roughly 1240 MW of electricity per year and may save approximately 325.56 tons of CO2 gas emissions annually to the environment per year as compared to using fossil fuel-based power plants to produce electricity.

This article provides a comparative analysis of various energy storage devices. A detailed review and analysis of molecular energy storage units is carried out, their main characteristics and parame-ters, as well as their application areas, are determined. The main types of molecular energy storage are determined: electric double layer capacitors, pseudo capacitors, hybrid capacitors. Comparison of the characteristics of various batteries is given. The parameters of various energy storage devices are presented. The analysis of molecular energy storage devices and accumulators is carried out. Ttheir advantages and disadvantages are revealed. It has been shown that molecular energy storage or double layer electrochemical capacitors are ideal energy storage systems due to their high specific energy, fast charging and long life compared to conventional capacitors. The article presents oscillograms of a lithium-ion battery with a voltage of 10.8 V at a pulsed load current of 2A of a laptop with and without a molecular energy storage device, as well as oscil-lograms of a laptop with DVD lithium-ion battery with a voltage of 10.8 V with a parallel shutdown of a molecular energy storage device with a capacity of 7 F and without it. The comparative analysis shows that when the molecular energy storage unit with a 7 F capacity is switched on and off, transient processes are significantly improved and there are no supply voltage dips. The dependenc-es of the operating time of a 3.6 V 600 mAh lithium-ion battery at a load of 2 A for powering mo-bile cellular devices with and without a molecular energy storage are given. It is shown that when the molecular energy storage device is switched on, the battery operation time increases by almost 20%.
