“…Hence, further experiments were limited to the PCWC samples only (i.e., groups S1-S4). The dielectric strengths of the PCCs from this study showed values between 6.1 and 16.5 kV/mm, which are within the ranges obtained for common insulating materials such as glass (5-10 kV/mm) and electro-ceramics (8-15 kV/mm) [33]. Other studies also indicated that PCCs incorporating acrylic and vinyl ester have dielectric strengths between 6 and 9 kV/mm [34,35].…”

This paper investigates the electrical, thermal and mechanical properties as well as the environmental performance of polymer cementitious composites (PCCs) as sustainable coating materials for underground power cables and as high-voltage insulators. Particular focus is placed on the optimised mix design and the effect of the manufacturing method on the performance of PCCs, incorporating liquid styrene and acrylic (SA) monomers, wollastonite and muscovite. Microstructural investigations, together with results from strength tests, indicate that the manufacturing method is a key performance parameter. Experimental results show that PCC mixes containing 25% SA emulsion, 12.5% wollastonite and no muscovite provide the most favourable dielectric properties from the mixes investigated. The PCC material has a dielectric strength up to 16.5 kV/mm and a dielectric loss factor lower than 0.12. Additional experiments also show that PCC has good thermal stability and thermal conductivity. The mechanical strength tests indicate that PCC specimens possess reliable strengths which are applicable in structural design. Environmental assessments also show that PCCs possess significantly lower embodied energy and embodied carbon than conventional plastic insulating materials.

“…Without having enough information regarding the panels behavior one cannot effectively size and design the photovoltaic systems. Intensive literature review reveals that in order to understand the performance of solar cells under variable light intensity and temperature, researchers have utilized solar simulators, and/or filtered lamp intensities in the laboratories (indoor condition) [7][8][9][10][11][12][13]. However, little attention has been paid on the practical investigation of inorganic solar panels under different sunlight intensities and temperatures in outdoor situations.…”

Abstract:In this work the impact of sunlight intensity and ambient temperature on the inorganic solar panels in winter climate (22 November 2015) at Sarwchawa, Kurdistan Region, Iraq was carried out. A maximum intensity of sunlight (106.25 klux) was reached at 12:00 PM. However, beyond 12:00 PM the intensity showed a non-monotonic change behavior. This was ascribed to the change of sun position, its orientation and the direction at which the surface of the panel is illuminated. Results showed that the increase of sunlight intensity has made I sc to increase, while that of the V oc remains relatively unchanged. The reason why I sc is more affected by the sunlight intensity was understood from the fact that charge carriers acquire enough kinetic energy to move towards their corresponding electrodes before they relapse or recombine together, while as V oc is mostly correlated to the energy gap. There was a trivial decrement of efficiency with the increase of temperature. This was where the FF showed a reverse trend of increment with the increase of temperature. Noteworthy, at the points where the fill factor was decreased the efficiency was increased and vice versa.
