“…The corrosion current (I cor ) was then derived from the well-known Thus, when compared to Magnelis® material, hot-dip Zn coating is characterized by signifi cantly increased corrosion current-densities (on the order of 9 and 14 μA cm -2 for fresh and the corrosion-tested samples, respectively) and the reduced values of the R p parameter -around 2860 and 1840 Ω cm 2 , correspondingly (see Table 2). Obtained corrosion current-densities could then be re--calculated to linear corrosion rates (V L ), according to equation 2 below: (2) where: k Zn is the electrochemical equivalent for Zn in /g A -1 h -1 /, I cor is measured corrosion current in /A/, S A is electrode's geometrical surface area in /m 2 / and d Zn is density of zinc in /kg m -3 /. Hence, the linear corrosion rates assessed at an initial stage of the corrosion process in sodium chloride solution came to about 64 and 137 μm year -1 for Magnelis® type and hot-dip Zn coatings, correspondingly.…”

This communication reports on the concerns associated with possible generation of galvanic coupling effects for construction materials that are used to manufacture mounting assemblies for ground-mounted photovoltaic (PV) power stations. For this purpose, six macro-corrosion galvanic cells were assembled, including: hot-dip Zn/ Magnelis®-coated steel/Al and stainless steel (SS)/Al cells. Corrosion experiments involved continuous, ca. threemonth exposure of these couplings in 3 wt.% NaCl solution, conducted at room temperature for a stable pH value of around 8. All corrosion cells were subjected to regular assessment of galvanic current-density and potential parameters, where special consideration was given to compare the corrosion behaviour of Zn-coated steel samples with that of Magnelis®-coated electrodes. Characterization of surface condition and elemental composition for examined materials was carried-out by means of SEM and EDX spectroscopy techniques.

“…In the last decade, the life cycle analysis (LCA) method has been applied to the systematic assessment of environmental issues in the PV supply chain by following a cradle-to-grave or cradle-to-cradle approach, in order to realize a "closure of the loop" [47][48][49][50][51].…”

Abstract:The purpose of this work is to carry out a review of the main technical-economic and environmental implications associated with the production of photovoltaic (PV) energy, one of the renewable sources for the production of electricity which currently presents the highest rate of growth worldwide-particularly in Europe and in Italy. The review provides a detailed exploration of the most important initiatives taken at the national level for the end-of-life management of the modules, and highlights issues associated with the disposal and/or recycling of obsolete photovoltaic panels in terms of techno-economic and socio-environmental sustainability. The paper highlights the main critical elements and potential opportunities deriving from the technological, managerial, and organizational options available to enhance recovery and recycling rates of PV panels in Italy. Results point out the importance of a circular economy perspective, through the involvement and awareness of the actors in the process, in order to render an even greener photovoltaic energy life cycle.

Exergy concepts and exergy based methods are applied to energy systems to evaluate their level of sustainability. Life Cycle Exergy Analysis (LCEA) is a method that combines LCA with exergy, and it is applied to solar energy systems. It offers an excellent visualization of the exergy flows involved over the complete life cycle of a product or service. The energy and exergy used in production, operation and destruction must be paid back during life time in order to be sustainable. The exergy of the material that is being engaged by the system will turn up as a product and available for recycling in the destruction stage. LCEA shows that solar thermal plants have much longer exergy payback time than energy payback time, 15.4 and 3.5 years respectively. Energy based analysis may lead to false assumptions in the evaluation of the sustainability of renewable energy systems. This concludes that LCEA is an effective tool for the design and evaluation of solar energy systems in order to be more sustainable.
