Tracking is important in a system that harnesses solar energy. Single axis tracking mechanism is cheaper and simple to develop but because of the limitation of tracking axis, this system is less efficient than dual axis. Dual-axis tracking systems necessitate a large number of equipment, sensors, motors, and a lengthy computer program to function properly. Therefore, in the present study, a novel method of solar tracking has been discussed where each tracking point has the impact of both the azimuth and altitude angle at a single point. This method is an average axis tracking method (AATM). HelioScope software was used to extract the hourly solar altitude and azimuth angles for each day and month for the site of Bhopal, India. The average method was then used to get the hourly average solar tracking angle (ASTA) for each month. The parabolic dish concentrator was designed in SolidWorks to apply and simulate the newly developed tracking points on SolTrace software. The graphical analysis was presented along with proper validation of the proposed method, and the single and dual axes were compared with AATM. The graphical study shows that the average axis tracking points have a smoother slop of wave than the single axis. From June to September, the proposed method's error was estimated between 0.85 and 0.95. It can be concluded that by making slight adjustments to the seasonal angle, this error could be minimized and the concept could be successfully applied to a parabolic dish or a solar PV system.
在利用太阳能的系统中,跟踪是很重要的。单轴跟踪机构价格便宜且易于开发,但由于跟踪轴的限制,该系统的效率低于双轴。双轴跟踪系统需要大量的设备、传感器、电机和一个冗长的计算机程序才能正常运行。因此,在本研究中,讨论了一种新的太阳能跟踪方法,其中每个跟踪点在单点上具有方位角和高度角的影响。这种方法是平均轴跟踪方法(AATM)。使用 HelioScope 软件提取了印度博帕尔地点每天和每月的每小时太阳高度和方位角。然后使用平均方法获得每个月的每小时平均太阳跟踪角(ASTA)。在 SolidWorks 中设计了抛物面碟形聚光器,以在 SolTrace 软件上应用和模拟新开发的跟踪点。提出了图形分析,并对所提出的方法进行了适当的验证,比较了单轴和双轴与 AATM。图形研究表明,平均轴跟踪点的波斜率比单轴更平滑。从 6 月到 9 月,所提出的方法的误差估计在 0.85 到 0.95 之间。可以得出结论,通过对季节角进行微小调整,可以最小化该误差,并成功将该概念应用于抛物面碟形聚光器或太阳能光伏系统。
