Abstract

Dual axis photovoltaic (PV) tracking system is considered in general to be a poor investment. This is mainly due to the substantial initial investment costs that these systems carry. However, in recent years, solar panels and accompanying component costs have decreased significantly. Additionally, electricity price hikes in South Africa have compelled most of the country’s citizens to reconsider their sources of electrical energy. A popular alternative to grid energy in South Africa is the use of photovoltaic systems. Careful consideration is required when choosing from the various systems available on the market. The main method for maximizing the output power of these systems is to introduce solar tracking systems. Therefore, in this paper, a model of a dual axis tracking system is developed and validated against a real-world plant in the Bloemfontein region in South Africa. The presented model was observed to be accurate to within an error rate of 6.39%. Additionally, the performance of the inverters of the PV tracking systems were evaluated and discussed. The validated model may prove to be an excellent tool for energy managers to determine the feasibility of such systems, compared to conventional photovoltaic setups.

双轴光伏跟踪系统的模型开发与验证:以南非为例

双轴光伏(PV)跟踪系统通常被认为是一个很差的投资。这主要是由于这些系统所携带的大量初始投资成本。然而，近年来，太阳能电池板和相关组件的成本大幅下降。此外，南非的电价上涨迫使该国大多数公民重新考虑他们的电力来源。在南非，一种流行的替代电网能源的方法是使用光伏系统。在选择市场上可用的各种系统时，需要仔细考虑。使这些系统的输出功率最大化的主要方法是引入太阳能跟踪系统。因此，本文开发了一个双轴跟踪系统模型，并针对南非布隆方丹地区的一个真实工厂进行了验证。结果表明，该模型的准确率在6.39%以内。此外，对光伏跟踪系统中逆变器的性能进行了评价和讨论。与传统的光伏装置相比，经过验证的模型可能被证明是能源管理人员确定此类系统可行性的绝佳工具。
