    The technology of solar energy power conversion has gained its importance in industries, agriculture as well as for domestic purpose. It therefore important for technician and an engineer to have good knowledge of solar power, its generation and its utilization. The solar energy received in the form of solar radiation(diffuse or beam radiation) is converted by direct or indirect energy conversions method. In this project, solar power is absorbed in sheet roof plate which is used for drying of vegetable and fruits. An forced convection solar drier and tested its performance for drying chili under the metrological conditions. The system consists of a sheet metal roof solar collectors used for air heating with a drying chamber, and a centrifugal vane blower. Drying experiments have been performed at an constant air flow rate. Keywords: Solar dryer, Forced convection, Sheet metal roof collector.

    The emerging process of utilizing the renewable energy resources is much more essential and need for human life cycle. In such a way of utilizing these energy forms we get the efficient product with the proper processing condition. Hereby the main renewable energy source used by the industries and farmers are considered as solar energy. Whereas the form of heat is utilized for drying the agro products can significantly reduce to reduce or eliminate product wastage, food poisoning and at the sometime enhance productivity of the farmers towards better revenue derived. In order to produce process heat for drying of agricultural, marine products, etc., solar energy is one of the promising heat sources for meeting energy demand without putti ng adverse impact of environment. Hence it plays a key role for sustainable development. Solar energy is intermittent in nature and time dependent energy source. In this project, solar power is absorbed in sheet roof plate which is used for drying of vegetable and fruits. An forced convection solar drier and tested its performance for drying chili under the metrological conditions. The system consists of a flat plate solar air collector used for air heating with a drying chamber, and a centrifugal vane blower. Drying experiments have been performed at an constant air flow rate. And the efficiency of the collector were achieved as up to 44.52%. Keywords: Solar energy, Solar dryer, Forced convective mode, Flat plate collector.
