Drying is the most seasoned safeguarding strategy of rural items and it is a vitality serious procedure. High costs and deficiencies of petroleum products have expanded the accentuation on utilizing elective sustainable power source assets. This analytical research is for the structure of an appropriate sunlight based warm sight-seeing heating framework for drying grounds nuts and to build a run of the mill level plate sun powered authority. After attentive investigation and research, a spending amicable and a do it without anyone’s help sight-seeing thermal warming system for drying ground nuts was intended to permit anybody that is intrigued to put resources into its development and advantage from its utilization. A progression of examination demonstrates that the sun oriented warm air warming framework can decrease the dampness content inside the groundnuts as the analyses demonstrated that the normal last dampness inside the groundnuts were 10.575% and 8.4%. The drying proficiency for the two examinations were observed to be 39.125% and 30.9% separately.
