摘要

小型太阳能光伏(PV)支架的高昂成本降低了光伏的采用速度。为了克服这些成本挑战,我们采用开放式硬件设计方法开发了两种新型可变倾斜支架设计。这是首款可通过改变电缆长度手动改变倾斜角度(从零度到 90 度)的支架设计。货架的设计采用了加拿大的自重、风荷载和雪荷载计算结果,作为世界其他大部分地区的保守设计。然后确定木质构件的结构承载力,并计算出其抗弯矩、抗剪力、抗拉力和抗压强度。进行结构和桁架分析,以确保货架设计能够承受适用的力。此外,还确定了改变倾斜角度对用于构建系统的木质构件/电缆的影响。与市场上的替代品相比,这些系统可节省三分之一到三分之二的资本支出,经济效益十分可观。此外,货架设计易于建造,只需最少的制造操作,这也增加了它们的可用性。棚架式设计可用于农业光伏设施,同时还能为农场工人提供符合人体工程学的遮阳通道,以便他们进行播种、除草和收割。

Wood- and Cable-Based Variable Tilt Stilt-Mounted Solar Photovoltaic Racking System
The prohibitive costs of small-scale solar photovoltaic (PV) racks decrease PV adoption velocity. To overcome these costs challenges, an open hardware design method is used to develop two novel variable tilt racking designs. These are the first stilt-mounted racking designs that allow for the manual change of the tilt angle from zero to 90 degrees by varying the length of cables. The racks are designed using the calculated dead, wind, and snow loads for Canada as a conservative design for most of the rest of the world. Structural capacities of the wooden members are then ascertained and the resisting bending moment, shear force, tensile force, and compressive force is calculated for them. A structural and truss analysis is performed to ensure that the racking design withstands the applicable forces. Moreover, the implications of changing the tilt angle on the wooden members/cables used to build the system are also determined. The systems offer significant economic savings ranging from one third to two thirds of the capital expenses of the commercially available alternatives. In addition, the racking designs are easy-to-build and require minimal manufacturing operations, which increases their accessibility. The stilt-mounted designs can be employed for agrivoltaic settings while allowing farm workers shaded, ergonomic access to perform planting, weeding, and harvesting.
