Can the Solar Hourglass serve as a CSP landmark?

by Wind Energy Update - part of the FC Business Intelligence Ltd group  (Nov. 11, 2014)

A CSP project proposal has won first place in the 2014 Land Art Generator Initiative (LAGI) competition, but can the design make it beyond paper? By Heba Hashem October was an eventful month for Santiago Muros Cortés. The Argentina-based architect impressed the jury in Copenhagen with his plan for a Solar Hourglass that ...

Solar Thermal System: Benefits Vs Problems?

by Greenshine New Energy LLC  (May 26, 2014)

Solar thermal systems are the latest green renewable technology that derives energy from the sun to produce heat. This heat is then transferred to warm water for utilization or regulates temperatures within households, offices and even industries. Varying qualities of equipment results in variation of performance in terms of efficiency and ...

Performance comparisons of grid connected SPV system with different MPPT algorithms

by Inderscience Publishers  (Feb. 19, 2015)

This paper presents a performance analysis of grid connected SPV system for different maximum power point tracking (MPPT) algorithms. The detailed mathematical model of grid connected three–phase solar photovoltaic (SPV) system with parametric model of SPV cell, thermal modelling and switching loss calculation of switching devices are discussed. ...

Exergy analysis of DSG parabolic trough collectors for the optimal integration with a combined cycle

by Inderscience Publishers  (Feb. 4, 2015)

A comprehensive energy and exergy analysis was conducted for various components of a direct steam generation (DSG) parabolic trough solar collector field under nominal operating conditions to assess performance of the components and to optimally integrate them with a thermal system. The solar field was modelled mathematically to compute thermal ...

Solar exergy maps for photovoltaic/thermal systems

by Inderscience Publishers  (Apr. 9, 2014)

In this paper, the thermal and electrical exergies and the exergy destructions are calculated for a photovoltaic thermal (PV/T) system based on solar exergy rates for some Indian climates namely Bangalore, Jodhpur, Mumbai, New Delhi and Srinagar for a year and for different US climates namely Chicago, Las Vegas, Miami, New York, Portland, San ...

by Inderscience Publishers  (Nov. 4, 2014)

The familiar umbrella has been redesigned for power harvesting from renewable energy sources resulting in the Eco-Brella . Several engineering technologies are utilised: aerodynamics for fin design, mechatronics for power management, materials for thermoelectric and solar film, CAD for the layout, and heat transfer for human comfort. The ...

Energy and exergy analyses of solar ponds in the Indian climatic conditions

by Inderscience Publishers  (Nov. 4, 2014)

Energy and exergy analyses of a salinity–gradient solar pond (SGSP) (100 × 100 m²) are carried out in the Indian climatic conditions. It has been found that the highest amount of useful low–grade thermal energy, i.e., 24,260 and 28,119 MJ, can be extracted at 80 and 85°C temperature from heat storage zone (HSZ) of the solar ponds at New Delhi and ...
