## 1. Introduction

^{3}, with a total net present cost (NPC) of USD 0.813 million. Rezzouk and Mellit [9] carried out the techno-economic feasibility and sensitivity analysis of a PV-Diesel-Battery-operated HRES, with the penetration of PV varying from 0% to 100%. From the results, it can be observed that system stability and optimum performance can be achieved with 25% PV penetration. A sensitivity analysis showed that global radiation has a significant effect on the NPC and CoE of the system. Rahman et al. [10] showed that biogas and solar systems can be integrated to develop a hybrid energy system that can meet both electrical load and thermal (cooking) demands, and can efficiently replace conventional facilities. The results also show that monetary savings worth USD 309 to 412 per year can be achieved by using the proposed hybrid renewable energy system. Considering climate diversity and the energy efficiency of buildings, Mokhtara et al. [11] investigated the optimal sizing and mapping of hybrid renewable energy systems for an off-grid building at seven different locations in Algeria. The results show that climate zone and the energy performance of the building have significant effects on the optimal sizing of the HRES. The study makes recommendations related to efficient energy management between energy sources, stored energy and load demand for the optimization of the overall HRES. Baruah et al. [12] carried out techno-economic feasibility analyses of an HRES for the academic township in Sikkim, India, using HOMER. The results show that the optimum system is a PV-Wind-Biogas-Syngas-Hydrokinetic-Battery-based system with an LCOE of USD 0.095/kWh. Al-bonsrulah et al. [13] carried out an analysis of a hybrid system for the Bahr Al-Najaf region. The results show that the energy contributions of fuel cell, wind turbine and PV are 4.38%, 26.3% and 69.3%, respectively. Katsivelakis et al. [14] performed a techno-economic analysis of a hybrid renewable energy system on Donoussa Island, Greece, by varying the contributions (20%, 50% and 100%) of renewable energy resources. The results show that with a 50% renewable energy contribution, a system can be obtained with 0% excess energy, an NPC of EUR 4,031,102.3 and a COE of EUR 0.2401/kWh. Kanase-Patil et al. [15] showed that an HRES with micro hydropower, biomass, biogas, solar energy, wind and energy plantation, with individual contributions of 44.99%, 30.07%, 5.19%, 4.16%, 1.27% and 12.33%, respectively, can provide for the electrical and cooking needs of seven off-grid villages in Uttarakhand, India. The results also showed that the optimal HRES system had 0.95 energy index ratio, at the optimized cost of Rs 19.44 lacs and a COE of Rs 3.36 per unit.

_{2}O) as the PCM, showed that the electrical efficiency of the PV panel was increased by 10% due to a reduction in its operating temperature by 8 °C. Stropnik and Stritih [23] showed that, with PCM, the surface temperature of the PV panel can be lowered by a maximum of 35.6 °C, resulting in 9.2% additional power compared to a conventional PV panel. Khanna et al. [24] analyzed a finned PCM integrated PV panel, showing that the power produced by the PV panel in a warmer climate increases in the range of 10.1% to 12.1%, and in colder climates it increases in the range of 5.4% to 6.7%, as compared to the reference PV panel.
