Automated dual‐axis planar solar tracker with controllable vertical displacement for concentrating solar microcell arrays

Abstract: Concentrator photovoltaics are able to maintain power output for extended hours while reducing the quantity of expensive high performance compound semiconductor solar materials. One of the limitations in concentrator photovoltaics is the bulky and heavy form factors of solar tracking systems which usually require dedicated installation locations and resistance to wind loading. This paper describes a planar solar tracker that requires only micro or millimeter scale lateral and vertical displacements of a microl… Show more

“…[14,27] Furthermore, micro-CPV enables the tracker integration in a module by moving internal subcomponents to continuously capture concentrated sunlight, with displacements of only a few millimeters needed. [34][35][36][37][38][39][40][41] A salient example is the integrated tracking approach from Insolight S.A. using a high acceptance double convex optic and a movable cell-plane. A measured electrical efficiency of 29% was achieved, and the technology is currently being commercially deployed.…”

“… Illustration of the accuracy of solar tracking by using CPV technology (Image ( a ): (1) solar cell, Ø = 3 mm; (2) heat sink; (3) direct, focused solar radiation (focal point [ 61 ]) set incorrectly; Image ( b ): (4) direct, focused solar radiation (focal point [ 61 ]) set precisely). …”

“…Other mechanisms that pursue the same objective have been published in the literature. 7,8 The planar micro-tracking enables Insolight modules to be installed at a fixed tilt in a static frame (Figure 1A). Direct sunlight is focused by a polymer lens array onto III-V triple-junction cells with a concentration factor of 180×.…”
