Solid particles impair the performance of the photovoltaic (PV) modules. This results in power losses which lower the efficiency of the system as well as the increases of temperature which additionally decreases the performance and lifetime. The deposited dust chemical composition. concentration and formation of a dust layer on the …

This book presents essential new governance structures to embrace and regulate smart mobility modes. Drawing on a range of case studies. it paves the way for new approaches to governing future transportation systems.    Over the past decades. Information and Communication Technologies have enabled the development of new mobility solutions …

The paper reports use of silicone oil as spectrum filter and heat absorber for photovoltaic thermal systems. The terrestrial solar spectrum is in the wavelength range of 0.25 to 2.5 μm. The response range of C-Si solar cell is 0.75 to 1.125 μm. In the current study. the feasibility of …

Purpose– Faults in the actual outdoor performance of Building Integrated Photovoltaic (BIPV) systems can go unnoticed for several months since the energy productions are subject to significant variations that could mask faulty behaviors. Even large BIPV energy deficits could be hard to detect. The purpose of this paper is to …

This book discusses major technological advances in the treatment and re-use of wastewater. Its focus is on both novel treatment strategies and the modifications and adaptions of conventional processes to optimize the treatment of a complex variety of pollutants. including organic matter. chemicals and micropollutants in different water resources. as …

The basic component of two-circuit geothermal systems is the heat exchanger. When used in geothermal power systems. conventional shell-and-tube and plate heat exchangers cause problems related to the cleaning of the latter from salt-deposition and corrosion products. Their lifetime does not exceed. as a rule. 1 year. To utilize the …

Lifetime of wind turbine inverters is below expectations therefore. novel design and drive strategies are timely required to achieve optimum life span. In this work. a novel driving strategy to mitigate stresses on inverters is proposed. First. an electro thermal analysis was carried out using finite element modelling methods. Subsequently. …

A practical guide to facilitate statistically well-founded decisions in the management of assets of an electricity grid Effective and economic electric grid asset management and incident management involve many complex decisions on inspection. maintenance. repair and replacement. This timely reference provides statistically well-founded. tried and tested analysis methodologies for improved …

This paper presents the design and test of a single phase and thermoelectric cooling Micro-Inverter using a DC-DC interleaved isolated boost. It focuses on the optimization of (DC-DC and DC-AC) converters performances and its physical dimensions. and presents an efficient method to track the maximum power point and the load …

The characterized wind electricity generation systems were statistically evaluated to assess the reduction in life cycle GHG emissions. A total of five unique categorization codes (HAWT-ON-S. HAWT-ON-I. HAWT-ON-L. HAWT- OFF-L. VAWT-ON-S) were designated to the 29 wind electricity generation LCA studies (representing 74 wind system cases) using the proposed categorization …
