The article deals with the optimization of the azimuthal tracking mechanism for a photovoltaic (PV) platform, which uses linear actuators as actuation elements for both movements (diurnal and elevation). In the case of diurnal movement, where the platform’s angular field of orientation is large, a mechanism with a relatively simple structure is used for amplifying the actuator’s stroke and avoiding the risk of the system locking itself (by limiting the values of the transmission angle). The optimization study targets the mechanical device, the control device, and the bi-axial tracking program (embodied by the laws of motion in time for the platform’s diurnal and elevation angles) with the purpose of obtaining a high input of solar radiation, with a minimal energy consumption to achieve tracking. The study is carried out by using a virtual prototyping platform, which includes Computer Aided Design (CAD), Multi-Body Systems (MBS), and Design for Control (DFC) computer applications. The mechanical and control devices of the solar tracker are integrated and tested in mechatronic concept. The simulations’ results, which were performed for a set of representative days throughout the year, prove the effectiveness of the proposed design.

In this article, we have designed and fabricated the gamma-type Stirling engine based on the compression ratio technique. This engine is attached on a parabolic dish of a solar collector. The engine shows a good performance in terms of compression ratio, external work, total pressure, and engine’s speed. Our engine offers the thermal efficiency of 30.59 % so that it can reach the output mechanical power of 0.934. The temperature difference of 137 K can maintain very well for the heat collection of the solar collector even when the weather conditions are poor. Furthermore, our materials are environmentally friendly and this design is expected to be in the applications of the solar tracker in the future.

Abstract. A portable Fourier transform spectrometer (FTS), model EM27/SUN, was deployed onboard the research vessel Polarstern to measure the column-average dry air mole fractions of carbon dioxide (XCO2) and methane (XCH4) by means of direct sunlight absorption spectrometry. We report on technical developments as well as data calibration and reduction measures required to achieve the targeted accuracy of fractions of a percent in retrieved XCO2 and XCH4 while operating the instrument under field conditions onboard the moving platform during a 6-week cruise on the Atlantic from Cape Town (South Africa, 34° S, 18° E; 5 March 2014) to Bremerhaven (Germany, 54° N, 19° E; 14 April 2014). We demonstrate that our solar tracker typically achieved a tracking precision of better than 0.05° toward the center of the sun throughout the ship cruise which facilitates accurate XCO2 and XCH4 retrievals even under harsh ambient wind conditions. We define several quality filters that screen spectra, e.g., when the field of view was partially obstructed by ship structures or when the lines-of-sight crossed the ship exhaust plume. The measurements in clean oceanic air, can be used to characterize a spurious air-mass dependency. After the campaign, deployment of the spectrometer alongside the TCCON (Total Carbon Column Observing Network) instrument at Karlsruhe, Germany, allowed for determining a calibration factor that makes the entire campaign record traceable to World Meteorological Organization (WMO) standards. Comparisons to observations of the GOSAT satellite and concentration fields modeled by the European Centre for Medium-Range Weather Forecasts (ECMWF) Copernicus Atmosphere Monitoring Service (CAMS) demonstrate that the observational setup is well suited to provide validation opportunities above the ocean and along interhemispheric transects.

This paper will discuss about the design of a portable photo voltaic electric generator capable of tracking sunlight in all directions. Such power generator is designed for disaster affected area with power outage, such as during major floods like Jakarta in 2012, or strong earthquake such as Yogyakarta in 2006 and Japan in 2011 (Tohoku) and 2016 (Kumamoto). Such occurence usually results in disruptions of public service, especially power grids. The system consists of a 10 Wp PV solar panels capable in two axes movement, which is 120° horizontal and 360° azimuth movement with ATMega8535 micro controller as the main controller. Two-axis movement is based on two types of sensors, 360° directional movement is based on the HMC5883 compass sensor. This compass sensor panel also be configured to always directs towards the sun so that if the direction of the base plate was changed, it will automatically direct the panel to the direction of the sun. While 120° vertical movement based on three pieces of LDR (Light Dependent Resistor) as sun sensors. The purpose of this system is to maximize the amount of light received by the panel so the panel power output is also maximized so it can generate emergency electrical supply for lighting and other basic needs.
