摘要：The Flat-plate solar collector is the heart of any solar energy collection system designed for operation in the low temperature range (ambient 60 0 C) or in medium temperature range (ambient 100 0 C). It is used to absorb the solar energy, convert it into heat and then transfer the heat into the stream of liquid or gas. It absorbs both the beam and diffused radiation, and is usually planted on the top of the building or other structures. It does not require tracking of sun and requires little maintenance. Thermal efficiency is the, ratio of useful gain to the incident energy over the same period of time. It is the basic parameter on which generally the effectiveness of a flat plat collector lies or is calculated. India is basically divided into six major climatic zones as follows: Hot & Dry, Warm & Humid, Temperate, Cold & Sunny, Could & Cloudy and Composite. The present study is carried out into cold & cloudy zone which covers major parts of northern India (Jammu & Kashmir, Parts of Himachal and Parts of Uttarakhand). It is noted that the coldest month of year in these parts is January with the lowest values of solar irradiation, so the climatic parameters of January are taken for the study.
