“…The standard value was assigned for some cost elements. They were 1) maintenance cost: 1% of capital cost [12] 2) salvage value: 5% of capital cost [17], 3) inverter replacement: 10% of the capital cost incurred every 10 years 4) degradation rate: 0.5% [17]. The electricity rates of the project commissioned year for different countries were taken from published material such as PORDATA [29] and [30].…”

“…This study used environmental and societal advantages and building material benefits in estimating the lifecycle cost of the system. Weerasinghe, Yang, Wakefield, Too, Le, Corkish, Chen and Wang [17] identified the economic performance of real 45 BIPV projects in Australia, North America, and Europe. The results revealed that BIPV possible be favourable when both direct and indirect benefits are counted.…”

“…LCOE is generally compared with retail electricity prices [18]. The lifecycle costs elements are included as capital cost, material replacement cost, maintenance and operation cost, salvage value, incentives, and inverter replacement cost [17,[19][20][21]. The capital cost represents the cost of modules, balance of system (BOS), installation, and procurement that is spent at the initial investment [18].…”

Building Integrated Photovoltaic (BIPV) which can be applied to various parts of the building envelope such as walls, roofs, windows, and facades provides untapped opportunities to produce green energy even to meet total building’s energy need. Although, there are buildings with successful applications, the growth of the BIPV among both PV and building industries is inadequate due to various reasons particularly technical complexities. However, currently, many technological advancements have been emerged meeting market expectations, eliminating the current obstacles. System performances always lead to the decision of BIPV adoption are varied continuously. This paper aims to investigate the impact of technology developments on the multiple performances: economic; structural substitutable; environmental of 46 BIPV projects in non-domestic buildings in western countries using levelised cost of energy, net present value, material offset and greenhouse gas emission savings. Sensitivity analysis identifies generate four scenarios i) capital cost, 2) electricity conversion efficiency, 3) share of grid supply and 4) lifetime. The results revealed that capital cost has substantial influence than others to uplift the performances. It is significant to optimise the share of grid supply and onsite consumption for favourable performances. The outcome empowers stakeholders to explore the significance of technology deployment.

“…8 The feasibility of using photovoltaic panels to provide part or all of the electricity required by buildings has been investigated in various studies. 9 However, in hybrid usage, the PVT system has been employed recently as a simultaneous way of electrical and thermal energy production in buildings. 10 The thermal collector under the PV modules is utilized to preheat or precool the air/water required by the building.…”

In this study, a multicriteria optimization is developed for a hybrid building integrated photovoltaic/thermal (BIPVT) system with a sensible rotary heat exchanger (SRHX) for both heating and cooling purposes. The BIPVT system is considered with and without considering the glass cover. Both the heat and electricity produced by the BIPVT-SRHX system are determined according to the energy and exergy phenomena. The objective functions aimed to be maximized are the annual total amount of generated energy and exergy. The length and depth of SRHX, geometrical parameters of PV modules, and the air mass flow rate are the parameters considered in the optimization. The results reveal a high amount of produced energy for the optimized design; however, the total amount of generated exergy is low. The system with the glass cover shows a higher amount of gained heat and less generated electricity compared with the system without the glass cover. The total energy produced by the system with and without the glass cover is about 227 and 220 MWh, respectively, and the total produced exergy by the systems with and without the glass cover is 1207 and 1585 kWh for the optimized design, respectively.

Towards Improving the Durability and Overall Performance of PV-ETICS by Application of a PCM Layer

et al. 2021

The main goal of the paper was to numerically analyse the risk of overheating of the Energy Activated External Thermal Insulation Composite System (En-ActivETICS) as an example of Building Integrated Photovoltaics (BIPV). The analyses were conducted with the coupled power flow method (thermal and electrical) for 20 European cities. All locations were analysed considering the local climate in the context of building performance simulation as well as electricity production. The obtained results allowed for the determination of the risk of overheating, which can influence system durability, accelerated thermal ageing, and overall performance. It was revealed that the risk of overheating above 80 °C is possible in almost all locations; however, the intensity considerably differs between southern and northern Europe. The effect of latent heat storage for better thermal stabilization and overall performance was determined numerically for all locations. Finally, the improved solution with a phase change material (PCM) layer beside the PV panel was proposed individually for specific climatic zones, considering the required heat capacity. The maximum panel temperature for improved En-ActivETICS does not exceed 85 °C for any location.
