Abstract
An experimental and numerical study was carried out on a storage solar collectors to verify its suitability for domestic use. These storage collectors can be used as storage water tanks to replace the ordinary cubical or cylindrical tank commonly used in Iraqi houses. The paper includes study the effect of the shape surface of absorber plate on performance of storage solar collector by construction of three-box type, built –in-storage water heaters with three different shape of front absorber plat, flat, wavy, and zigzag shapes. Experiments were conducted in summer and autumn seasons, and the results were comparable to the theoretical calculation. The results indicated clearly that the storage collector can be used for providing hot water for domestic uses, the zigzag storage collector was the best to obtain a high temperature than the other two designs, also the finite difference model proved to be useful for prediction of water temperatures under variable operating conditions.
