Operation and maintenance (O&M) cost will be the key to the economic viability of large offshore wind farms planned worldwide. In order to support investment decisions a systematic mathematical approach to the O&M cost contributions is required prior to detailed engineering or even construction...

The accurate simulation of a photovoltaic solar cell requires the precise determination of modelling parameters specific to the device under study. For the case of the single diode model, five parameters must be determined; Iph, I0, Rs, Rsh, and n. Generally speaking these values may be calculated...

This paper characterizes and compares the degradation observed in thin-film module performance. Three commercially available thin-film modules comprising a-Si:H, a-Si:H/a-SiGe:H/a-SiGe:H and CuInSe2 technologies were used in this study. After an initial indoor assessment the modules were...

Until now, there is no internationally accepted guideline for the measurement, data exchange and analysis of PV–Wind Hybrid Systems. As there is a need for such a tool, so as to overcome the barrier that the lack of confidence due to the absence of reliability means for the development of the...

The analysis in steady state of the different modelizations made on solar flat-plate functioning in low and average temperatures (especially the bridges of surface water) has allowed us to develop a simple linear model. By a swift experimental way, this model is able to approximate the thermal...

This paper investigates the micro-structural, chemical and crystalline properties of yttrium-stabilized zirconia (YSZ) thin films by using pulsed laser deposition (PLD), atomic layer deposition (ALD) and sputter. Atomic ratio of Y:Zr of YSZ thin films fabricated by three different deposition...
