7. TENTATIVE RESEARCH AREA SOLAR ENERY Energy from the Sun is referred to as solar energy. Solar energy is a renewable form of energy. It is obtained by capturing heat and light from the Sun. Solar energy is abundantly available and has been utilized since long both as electricity and as a source of heat. Solar technology can be broadly classified as (1) Active Solar − Active solar techniques include the use of photovoltaic systems, concentrated solar power and solar water heating to harness the energy. Active solar is directly consumed in activities such as drying clothes and warming of air. (2) Passive Solar − Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light-dispersing properties, and designing spaces that naturally circulate air.

8. INTRODUCTION Solar drier Solar dryers are devices that use solar energy to dry substances, especially food. There are two general types of solar dryers: Direct and indirect

9. INTRODUCTION Types of Solar Dryer Direct Solar Dryer –In this type of drier item or food is exposed directly to solar radiation through a transparent material that covers the structure. The heat generated from the solar energy is used to dry the crops or food items and also heats up the surroundings. The main disadvantage of using the direct mode is that the heat that will be absorbed by the item cannot be controlled. Indirect Solar Dryer – As the name suggests, this method does not expose the crop directly to the sunlight. The solar radiation is absorbed and converted into heat by another surface (like a black top) usually called the collector. Air that will be used for drying is passed over this surface and gets heated, which is then used to dry the food item inside the dryer. The main advantage of indirect mode of drying is that the temperatures can be controlled.
