Abstract

Pakistan is located on the world map where enough solar irradiance value strikes the ground that can be harnessed to vanish the existing blackout problems of the country. Government is focusing towards renewable integration, especially solar photovoltaic (PV) technology. This work is focused to assess the techno-economic viability of different PV technologies with aim of recommending the most optimum type for domestic sector in high solar irradiance region of the country. For this purpose, standalone PV systems are installed using monocrystalline (m-Si), polycrystalline (p-Si), and amorphous crystalline (a-Si) modules on the rooftop at 31.4 oN latitude position. The performance of PV modules is evaluated based on, average output power, normalized power output efficiency, module conversion efficiency, and performance ratio. Results elaborated that m-Si module is the optimum type for the application with 23.01% average normalized power output efficiency. Economics of the system has also been evaluated in terms of the price of power value produced by PV modules with respect to the consumption of that power value from grid source in base case. Integration of such type of domestic PV systems are a need of time to make the future sustainable.

Highlights

  • Energy is the main driving force behind the dynamics of the world

  • The standalone PV system is a type of off-grid system that generates direct current (DC) electric power

  • A standalone PV system setup was installed at the rooftop of Faisalabad, Pakistan

Summary

Introduction

Energy is the main driving force behind the dynamics of the world. The whole world is running after energy sources to make the future brighter and sustainable. With scientific technology advancement in 21st century, innovative techniques and inexhaustible energy sources are making their way to meet new standards. In this context, renewable energy sources (RESs) are the focus as they are everlasting and are not associated with threat of being extinct, as fossil fuels are. Significant amount of energy security, climate change mitigation, and certain economic benefits can be achieved by the speedy deployment of RESs [1,2,3]
