Solar MEMS has established itself as one of the main suppliers for solar sensors in the global aerospace market. This success has been founded on technology that has constantly advanced, and a development team that is fully dedicated to meeting the challenges that are set for it. Today we are focusing on Production Manager Isaac Fernández, a man who thrives on the day-to-day challenges of ...
Discharge lamps are lamps that produce light thanks to the ionization of gas by means of electric voltage. The mains voltage is not sufficient to strike discharge lamps, therefore, it is necessary to make use of particular electrical components called “Igniters”. For over 70 years IREM has been a leading company in the field of power supply and ignition of discharge lamps. Thanks to ...
Solar Simulator or Xenon Light Source There are many companies in the market place that claim to sell solar simulators, yet what they are really selling is a xenon light source. ...
Learn about how the Eclipse X solar car team uses solar forecasting in its race strategy! Solar forecasting for the Eclipse X Solar Car This week, we have a guest blog post from the Eclipse X solar car team, who are accessing the Solcast API to support their race ...

To evaluate the performance of zeolite-supported carbon-doped TiO2 composite catalysts toward target pollutants under solar light irradiation, the adsorption and photocatalytic degradation of 18 pharmaceuticals and pesticides with distinguishing features (molecular size and volume, and photolysis) were investigated using mordenite zeolites with SiO2/Al2O3 ratios of 18 and ...
The photocatalytic activity of the N-doped ZnO/HNTs catalysts was evaluated by the degradation of methyl orange (MO) solution with the concentration of 20 mg/L under the simulated solar-light irradiation. The result showed that the N-doped ZnO/HNTs catalyst exhibited a desirable solar-light photocatalytic activity. ...
Ag speciation in a chloride medium was dependent upon the Cl/Ag ratio after releasing into surface water. In this study, the photoreaction of in situ formed Ag–Cl species and their effects on aniline photochlorination were systematically investigated. Our results suggested that formation of chloroaniline was strongly relevant to the Cl/Ag ratio and could be interpreted using the ...

Estimation of solar radiation from measured air temperature offers an important alternative in the absence of measured solar radiation because of the wide availability of air temperature data. Solar radiation is considered as the most important parameter in meteorology, solar conversion, and renewable energy applications. ...
A linear Fresnel reflector solar concentrator (LFRSC) system is used nowadays for operation at intermediate temperature ranges by using solar energy. Considerable attention is being paid to the design, fabrication and testing of solar concentrators. The performance of the system depends on the design parameters, mass flow rate, desired ...
Artificial neural networks have been used by the author in the field of solar energy for the estimation of solar radiation data. The main objective of this paper is to present an overview of the AI–techniques for prediction of solar radiation data. Published literature presented in this paper show the potential of AI as a design tool for the ...
Optimization of the CPV existing technologies The DA and the PF systems have been first optimized starting from the core of such technologies: the solar cell. The main aim is to reduce the overall CPV-Cell Economical Performance Index, that is, to get solar cell with higher efficiency, concentrator factor and yield at reduced cost. ...
Most conventional solar thermal radiation concentrators have some sort of symmetry which allows them to concentrate solar thermal energy for their operation. We report a new system that utilises the symmetry of a cone and a cylinder combination to simulate the concentration of solar radiation on a ring containing a fluid (water). ...
The fundamentals for direct steam generation in parabolic troughs have been developed in recent years, the feasibility was successfully demonstrated at a solar powered test facility reaching steam temperatures of 400°C at a maximum pressure of 100 bar. ...
This paper presents high performance setup developed at the SolarLab to measure curient-voltage (I—V) curves of solar cells. The core of a setup is a steady light solar simulator of class A, according to specifications oflEC 60904-9 andASTM E927 standards. Available range of measurements enables us to characterise not only all kinds of ...
