effect of temperature coefficient and efficiency of pv technologies on 3e performance and hydrogen production of on-grid pv system in a very hot and humid climate

Although hydrogen is in its early stages in iran, its development capacity is high. considering the importance of these issues, this paper examines for the first time the production of hydrogen from solar energy in the hot and humid climate of iran. for this purpose, five stations have been selected in khuzestan province, and using homer v2.81 software, the annual solar electricity production of a 20 kw power plant connected to the grid has been calculated considering five types of solar panels (mono-crystalline, poly-crystalline, cigs, cdte, amorphous). then, using analytical equations and a solid oxide electrolyzer, the annual hydrogen production has been calculated. the results showed that amorphous technology is the most suitable in terms of cost, and cdte technology is the most suitable in terms of energy production and pollutant reduction. in total, among the studied stations, masjed-e soleyman city had the highest electricity production, highest hydrogen production, highest co2 emission reduction prevention, and lowest cost per kwh produced with values of 37,492 kwh/year, 1,254.4 kg/year, 1,768 kg/year and $0.072/year respectively. among the studied stations, ahwaz was found to be the least suitable station.
