Special Issue Information

Dear Colleagues,

Energy is considered one of the main parameters of any country’s socio-economic development. Over the years, conventional energy sources have been used to meet growing energy demands. The production of electricity is mainly dependent on conventional energy sources. An uncontrolled harnessing of limited sources will cause depletion of global oil and gas. One of the major challenges facing the world today is the increase in concentrations of greenhouse gases in the environment, which is generally caused by the substantial use of fossil fuels. Due to the limited availability of fossil fuels and rising air pollution, the replacement of fossil resources by renewable energy has become inevitable. Therefore, conservation of fossil fuels and exploration of possible alternatives are the prime challenges. Solar energy is a clean and abundant source of renewable energy. High levels of solar irradiance over a wide area of the globe make this energy a suitable source for power generation from solar photovoltaic (PV) and hybrid photovoltaic/ thermal (PV/T) systems. In fact, PV/T technology is the most significant innovation of recent times and can simultaneously generate heat and electricity from sunlight.

This Special Issue, entitled “New Insights into Techno-Economic and Environmental Assessment of Photovoltaic/Thermal Systems”, will discuss the energy potential and economic viability of the PV/T system as an alternative to fossil fuels for addressing critical environmental issues. Research topics include, but are not limited to, nanotechnology, phase change materials, thermal storage systems, new/novel working fluids, and materials for the solar systems. We are interested in the most recent PV/T technologies and their applications to residential, industrial, agricultural, and other potential sectors with particular interest in environmental assessments and global-scale economic competitiveness. Research and review papers, case studies, experimental, and analytical and numerical studies are welcome.

In this study, for the first time an advanced exergy analysis was applied to a solar hybrid food dehydrator to find out the causes of the inefficacies and to assess the actual improvement potential. The dryer was integrated with an evacuated solar tube collector and gas burner as a heating sources. Drying experiments were performed using bell pepper at 55 °C under three heating options i.e., gas, solar and dual. The rates of exergy destructions were split into unavoidable (EdUN) and avoidable (EdAV) which further split into four parameters termed unavoidable endogenous (EdUN,EN), unavoidable exogenous (EdUN,EX), avoidable endogenous (EdAV,EX) and avoidable exogenous (EdAV,EN). Conventional exergy analysis revealed that drying chamber possess lower improvement potential rate (IP) than heating components while outcomes of advanced exergy analysis showed that both the design and system components interaction of heating unit imparted a major effect on its efficiency. Optimizing the operating conditions of the heating sources could reduce their higher amount of inefficiencies. The values of exergy efficiency for the overall system were calculated to be 86.66%, 84.18%, 83.74% (conventional) and 97.41%, 95.99%, 96.16% (advanced) under gas, dual and solar heating modes respectively.

This paper presents the results of a field study undertaken all over the Punjab, Pakistan, to evaluate the socio-economic and climatic impact of photovoltaic-operated high-efficiency irrigation systems (HEIS), i.e., drip and sprinkler irrigation systems. Nearly half of the rural population relies on agriculture for a living, and the recent energy crisis has had a negative impact on rural communities. Farmers’ reliance on fossil fuels for the operation of irrigation systems has increased exponentially, resulting in the high costs of agricultural production. Primary data regarding on-farm agriculture and irrigation practices used in this study were collected through an intensive on-farm survey, while secondary data were taken from published reports and statistics. The results of the current investigation show that the installation of PV systems has resulted in the increased adoption of high-efficiency irrigation systems, a reduction in the high operational costs incurred on account of old diesel-powered pumping systems (with an annual saving of 6.6 million liters of diesel), a 100% increase in farmer’s income, a reduction of 17,622 tons of CO2 emissions per annum, and 41% savings in water. The unit cost of PV-powered HEIS was found to be 0.1219 USD/kWh, which was 4% and 66% less than subsidized electricity cost and diesel cost, respectively. Full article
