Analysis of the Solar Energy Collection for In-Plane Rotation Two Axes Micro-Tracking Systems
Concentrator photovoltaic technologies (CPV) have long been regarded as the obvious way to increase the solar power collection efficiency but the use of bulky two axes tracking systems has been proven to be a fatal handicap for both economic and technical reasons. On the other hand, the continuous development of multijunction high efficiency solar cells encourages the research of novel CPV architectures that can leverage the new cells potential. Here we present a study on the solar energy collection of an ideal hybrid two axes micro-tracking system suitable for rooftop installations. In this study, we analyze in detail the optimal installation angle in relation to the latitude and the partial shading effect on modules of the same solar panel. The study is focused on optimizing the average collection efficiency over the astronomical year period as opposed to maximize the collection on any given day of the year. Additionally, we conducted a techno-economic analysis of the hybrid In-Plane Micro Tracker, using “Bottom-Up” methodology for determining the cost of the micro-tracking concept where the materials, assembly, utilities, maintenance costs are included for each step of the manufacturing process.
