Conventional energy supply has not been able to meet the energy needs of most developing nations. This calls for the need to invest in renewable energy systems which are not only sustainable but clean, abundant, and easily assessable. This research presents a study of wind variability by using wind data got from a weather station to design and fabricate a small-scale horizontal axis wind turbine (HAWT). This was done by using locally sourced materials for a Hybrid Solar-Wind power system for irrigation purposes, as a performance evaluation of the turbine. The materials used in the fabrication of the turbine include wood, polyvinyl chloride plastic, acrylic glass, Teflon, and steel all sourced locally. From the evaluation, the power capacity of the wind turbine was derived to be 40 W, 41 W and 43 W from the voltage and current output reading on the multi-meter from three average wind speed variations of 5 m/s, 10 m/s and 15 m/s measured from handheld digital anemometers respectively. A regression analysis of the relationship between the turbine's power capacity and the wind speed showed that the turbine operates best at low speed of 5 m/s, with an R value of 0.9602. The fabricated wind turbine was connected to a hybrid power system with the second energy source consisting of a 40 W solar tracking system to give a more stable power supply. The system was used for soil monitoring irrigation purposes. The design of the HAWT indicates a cheap, alternative and sustainable energy source that is more stable and suitable for smart solar panel irrigation system.
传统能源供应已无法满足大多数发展中国家的能源需求。这就需要投资于可再生能源系统，这些系统不仅可持续，而且清洁、丰富且易于获取。本研究通过使用从气象站获取的风力数据来设计和制造一台小型水平轴风力涡轮机（HAWT），对风力变化进行了研究。这是通过使用本地采购的材料构建一个用于灌溉目的的混合太阳能 - 风能发电系统来完成的，以此作为对该涡轮机的性能评估。制造该涡轮机所使用的材料包括木材、聚氯乙烯塑料、丙烯酸玻璃、特氟龙和钢材，均在本地采购。通过评估，根据手持数字风速仪分别测量的5米/秒、10米/秒和15米/秒这三种平均风速变化，从万用表上读取的电压和电流输出读数得出该风力涡轮机的功率容量分别为40瓦、41瓦和43瓦。对涡轮机功率容量与风速之间关系的回归分析表明，该涡轮机在5米/秒的低速下运行最佳，R值为0.9602。制造的风力涡轮机与一个混合电力系统相连，第二个能源由一个40瓦的太阳能跟踪系统组成，以提供更稳定的电力供应。该系统用于土壤监测灌溉目的。水平轴风力涡轮机的设计表明这是一种廉价、替代且可持续的能源，更稳定且适合智能太阳能板灌溉系统。
