Аннотация: The ideal altitude angle for evacuated tube solar collectors, taking into account factors such as solar radiation availability, geographical location, seasonal variations, and collector tilt, is taken into account in this comparative analysis. This study focuses on obtaining the best thermal energy that can be obtained from the falling sunlight to increase the thermal efficiency of the solar collector. This model uses a Cartesian direction model (x, y, and z) and mathematical ordering methods to generate a 3D model. COMSOL 5.6 is then utilized to link the framework with mathematics and simulate the case. Solar radiation increases from March to June, peaking from 5-6 a.m. to 18-19 p.m. during the summer. The highest solar evaluation and azimuth occurred at 12 hV in the south direction. Temperature has a major impact on the performance of water heaters and vacuum tube solar collectors. The specific tilt angle analyzed is 40 degrees. The location where the analysis was done is Baghdad. The optimal tilt angle was found at 25° at the start of the day and reached 40° at 12 p.m. The best case was reached when the angle was 40 degrees. The magnitude of efficiency improvements was seen; the value of efficiency reached 78% compared to other cases. Where the difference is between it and the angle of 0 degrees altitude, at which the efficiency rate reached 64%, the amount of improvement is 14%.
