Heat pipe, being a passive energy system with a high heat transfer rate ability, can aid in ameliorating the performance of solar collectors as well as photovoltaic panels.
The heat loss resulted in solar thermal energy harvesting application, and the heat accumulation resulting in solar PV application can be minimized only with an effective heat-transferring system. Heat pipe, a passive heat transfer system, is well-becoming to address the aforementioned issues in the solar energy systems.
The utilization of heat from the PV cooling makes the current system a hybrid system where panel cooling and energy recovery are possible. The heat pipe applications are also suitable for the concentrated heat flux solar applications owing to the need for a high heat transfer rate ( Singh, and Reddy, 2020 ).

A current is generated under this voltage stress, known as leakage current., Na+) on the solar cell surface leads to potential induced degradation (PID). This results in the degradation in the performance of a solar cell.
There are two distinct methods to eliminate the leakage current in the solar PV array system: (i) obstruct the leakage current, (ii) reduce the variation/constant common-mode voltage. The additional diodes/switches are incorporated in the system to obstruct the leakage current by disconnecting the PV array from the grid side network.
The additional diodes/switches are incorporated in the system to obstruct the leakage current by disconnecting the PV array from the grid side network. The second approach involves the elimination of zero switching states . To address the aforementioned issues, the transformerless SECS is presented in .
The leakage current is induced in the SECS because of having a variation in the common-mode voltage. The typical r.m.s. value of the leakage current is 1.75 A, which is higher than recommended limit of 300 mA, thereby, it violates the VDE-00126-01 standard.
The solar PV array current is not varied, which evinces that maximum power generation is not varied. The grid currents are well-balanced and sinusoidal, which illustrates that the negative sequence power is not injected from the SECS. Fig. 14d shows the waveforms of VCM, ILeak, isa, iLaa.
However, it is unable to suppress the leakage current as a common-mode voltage is not maintained constant throughout the system operation. In this study, a three-phase SECS is presented herein to ameliorate the PQ of the grid and to suppress the leakage current.
Owing to the presence of stray capacitance between solar photovoltaic (PV) array and the ground, the variation in common-mode voltage across stray capacitance leads to potential safety issues, electromagnetic interference, and distortion into the injected grid currents.
Recharging batteries with solar energy by means of solar cells can offer a convenient option for smart consumer electronics. Meanwhile, batteries can be used to address the intermittency concern of photovoltaics. This perspective discusses the advances in battery charging using solar energy.
Solar energy offers the potential to support the battery electric vehicles (BEV) charging station, which promotes sustainability and low carbon emission.
Solar or photovoltaics (PV) provide the convenience for battery charging, owing to the high available power density of 100 mW cm −2 in sunlight outdoors. Sustainable, clean energy has driven the development of advanced technologies such as battery-based electric vehicles, renewables, and smart grids.
In a world reliant on smartphones, iPods, and smart watches, the persistent need for battery charging, particularly in areas devoid of electrical infrastructure, poses a formidable challenge. Solar power, a renewable energy source, emerges as a promising solution for mobile device charging, tapping into the sun's limitless energy potential.
The current technical limitations of solar energy-powered industrial BEV charging stations include the intermittency of solar energy with the needs of energy storage and the issues of carbon emission and maintenance of solar arrays.
In a study by Bhadra et al., design and development of a charging station feed with solar power and grid was focused. They applied an advance high gain boost converter instead of transformer for feeding the solar power with low voltage to the grid, which is used in general in other similar systems.
Solar energy charging for EVs is also deployed in two Scandinavian cities with scenario-based modelling . EVs include the commercial and private usage types, namely private electric vehicles (PREVs) and electric taxis (ETs), which are very common in developing and developed cities .
