Cost analysis of solar parabolic trough collector for cooking in Indian hostel – a case study. Issue 1 (31st December 2022) - Motwani, Karan
Abstract : The primary fuel used for cooking in most of the hostels in India is LPG which costs around 700–1500 rupees per cylinder. The temperature requirement for most of the meals to be prepared is in the range of 60–100°C, and majorly all of them require heating in the form of boiled water or steam approximately ≥ (100°C) for cooking. In the present case study, a sample of 1000 students is taken, consuming meals of two times. The integration of conventional LPG system with parabolic trough solar collector is studied and detailed cost analysis is carried out. Based on the above case study, the parabolic trough solar collector integrated system with LPG leads to a reduction in 15 tonnes of CO2 /year with a suggestable payback period of 2 years.
