“…They found that the 90o tilt angle gave the maximum output [6]. Patanasemakul et al in 2017 used reflective secondary optic to improve radiation uniformity in concentrating sun incident and improve the fill factors up to 5-15%, and maximum power up to 10% improvement [7]. However, the reflective mirror does not apply for PV system applications that required motion, such as PV panels to power a mobile robot applied in agriculture.…”

Indonesia has a high potential for renewable energy, especially solar power, due to its location in the equator and blessed with an abundance of sunlight. However, the energy potential from the sun is not maximally utilized. One of the efforts to increase the generated electricity and efficiency is by applied the panels in arches setting. This setting is made possible by the availability of the semi-flexible monocrystalline solar panel. This paper investigates the increment of harvested power and efficiency by arranging the solar panel in concave, convex, and plane settings. The data were taken in August 2019, where Palembang experiences the dry season and January 2020 during the rainy season. The highest power produced (20.27 Watt) and efficiency (13.14%) were achieved in a concave setting during the dry season. The convex setting produced more power and efficiency (13.26 Watt and 9.30%) compared to the plane setting (10.24 Watt and 9.71%). These results show that arches setting are more efficient to harvest solar power and give more extensive applications such as to power a dynamics mobile robot applied in agriculture.

This paper presents the design and fabrication of a micro-optic concentrator for optical radiation based on coupled micro-lenses and micro-prism (micro – mirrors) arrays. This type of micro-optic concentrator is suitable for both terrestrial and spatial applications where optical radiation is redirected and coupled to small area photovoltaic cells or detection devices located in front of the waveguide edges. Analysis and design were performed for the 0.4-1.06µm spectral range using the COMSOL Multiphysics program and the Ray Optics geometric optics module. Simulations for ray-tracing have been modeled in order to optimize the geometries of micro-optics elements taking into account the optical parameters of the materials to be used (polymers and glass) in the process of micro-optic concentrator fabrication. Micro-lenses and micro-prism arrays were fabricated by the technique of molding in silicon molds and replication in polymeric materials using OrmoClear30 elastomer (n=1.56, UV exposure) and in UV-PDMS, KER4690 polymer, respectively. Assembling and the fabrication process of micro-optic concentrator allowed the achievement of an optical efficiency of 70 % efficiency.
