This paper stories on the optimization of thin-film coating-assisted, self-sustainable, off-grid hybrid energy era techniques for cattle farming in rural areas of Bangladesh. Bangladesh is a decrease middle-income nation with declining charges of poverty amongst its 160 million individuals as a result of persistent financial development together with balanced agricultural enhancements. Many of the rural households undertake a blended farming system by cultivating crops and concurrently rearing livestock. Among the many animals raised, cattle are thought-about as probably the most priceless asset for the small-/medium-scale farmers when it comes to their meat and milk manufacturing. Presently, together with the key well being concern, the COVID-19 pandemic is hindering the world’s financial development and has thrust tens of millions into unemployment; Bangladesh can also be on this loop. Nevertheless, pure disasters akin to COVID-19 pandemic and floods, largely constrain rural smallholder cattle farmers from climbing out of their poverty. Specifically, small- and medium-scale cattle farmers face many points that impede them from benefiting from market alternatives and imposing a better burden on their households and incomes. An applicable measure may give a method to make these cattle farmers’ companies each worthwhile and sustainable. Optimization of thin-film coating-assisted, self-sustainable, off-grid hybrid energy era system for cattle farming is a brand new and forward-looking method for sustainable improvement of the livestock sector. On this research, we design and optimize a thin-film coating-assisted hybrid (photovoltaic battery generator) energy system by utilizing the Hybrid Optimization of A number of Vitality Assets (HOMER, Model 3.14.0) simulation instrument. An evaluation of the outcomes has prompt that the off-grid hybrid system is extra possible for small- and medium-scale cattle farming techniques with long-term sustainability to beat the numerous challenges confronted by smallholder cattle farmers in Bangladesh.
