Studies on Utilization of Solar Energy in Tasar Post Cocoon Technology Operations
摘要
Solar radiation varies between 600 and 1200 W/m2 during September–May and adequate radiation is available from morning 10 AM to afternoon 1 PM. Due to cloudy weather in rainy seasons during June–August, minimum value of solar radiation 400–600 W/m2 was found. Solar radiation 600 W/m2 and more is essential for effective electricity generation. Since minimum 0.25 HP/0.18KW power is required to operate each reeling or spinning machine, so solar plant generated electricity can be effectively utilized in tasar post cocoon sectors. About 45% solar energy can be utilized during November–March and 30% during April, May, September and October in a year whereas in rainy seasons (June–August) only 15% can be achieved. Effective generation of electricity was found between 10 AM and 1 PM as evaluated by principal component analysis and solar radiation during this time contributes about 93% whereas 5% only exists at 4 PM. Hence the electricity produced from solar power plant can be used as supporting in tasar post cocoon reeling and spinning processes. Besides utilization as supporting source of energy, it does not create environmental pollution like burning of coal, rice husk etc.
