摘要

平面微跟踪聚光光伏系统允许在面积受限的应用中产生更高的功率。为了保持传统太阳能电池板的外形，需要一个高精度的集成横向微跟踪系统。我们构建了一种基于形状记忆合金的致动器，该致动器可以利用少量的微单元偏移作为反馈，实现微单元在反射透镜阵列对之间的平移。这种无电机方法提供了一个简单的机械微跟踪系统，在14mm的投掷范围内具有10~\mu \math {m}$的精度，由$ < 1$ %的面板产生的功率提供动力。

Motorless Microtracking for Rooftop CPV

Planar microtracking concentrating photovoltaic systems allow higher power generation in area-constrained applications. Maintaining the form factor of traditional solar panels requires a high-accuracy integrated lateral-microtracking system. We constructed a shape memory alloy-based actuator which can translate the microcells between a catadioptric pair of lenslet arrays using a few of the cells offset for feedback. This motorless approach provides a simple mechanical microtracking system with $10~\mu \mathrm {m}$ precision over a 14mm throw powered by $ < 1$ % of the panel-generated power.
